How many squares are in the isover insulation. Technical characteristics of thermal insulation isover

"Izover" is a heater, the technical characteristics of which make it possible to judge it as one of the most effective materials to date. He has very broad scope applications. It is made of fiberglass and comes in the form of easy-to-mount plates and mats. It is used both to isolate small private houses, and high-rise buildings or industrial buildings. Also, this type of insulation is very well suited for protecting water pipes and other household communication systems from the cold.

How is it made

So, what is the Isover insulation? The characteristics of any depend primarily on how accurately the required technologies will be observed in the process of its production. Isover insulation is made as follows:

• Broken glass, limestone, and other minerals are pre-mixed thoroughly.
• The resulting mixture is melted at a temperature of 1300 gr. until a homogeneous fluid plastic mass is obtained.
• In a special installation, this liquid glass is fed from a great height onto a bowl rotating at high speed, in the walls of which there are small holes. Under the influence centrifugal force hot mass is squeezed out in the form of long thin threads.
• The fibers are mixed with a yellow polymer adhesive.
• The resulting sticky mass is fed into a special furnace, where it is rolled between steel shafts and blown with hot air. As a result, the glue seizes, and the layer itself is leveled.
• Finished glass wool goes under the circular saws for cutting into slabs of the required size.

Material advantages

The advantages of the Izover insulation (the characteristics of which will be discussed below) include primarily:

• ease of installation;
• low degree of thermal conductivity;
• high degree of fire resistance;
• universality;
• light weight;
• excellent soundproof qualities;
• low cost.

Insulation disadvantages

Of course, like any other building material, Izover plates also have certain disadvantages. These include:

• questionable environmental safety;
• the need to use protective clothing during installation.

All fibrous materials, including Izover (whose otherwise very good characteristics), absorb water well, which is why they lose a significant part of their heat-preserving qualities.

Scope of application

• wall insulation;
• heat and sound insulation internal partitions;
• stone and wooden houses in a warming cake;
• wall cladding from the inside;
• insulation of floors both from above and from below;
• roof insulation in houses residential attics and attics;
• winding pipes of communications.

Foundations are usually insulated with polystyrene foam. When using Isover for this purpose, it is necessary to additionally arrange very high-quality waterproofing.

"Izover": characteristics

Of course, before choosing this material for home insulation, you should find out what specific properties it has. There are several varieties of Isover insulator. They are all slightly different in features. Materials of this brand are produced with different indicators of density and thermal conductivity.

Insulation "Isover Classic" characteristics, for example, has the following:

This type of Isover insulation is on this moment the most popular. Other types of insulators of this brand also have good qualities.

Isover is supplied, the characteristics of which, therefore, make it possible to judge it as a really effective insulation, in slabs and mats that are convenient for installation.

Mounting Features

The frame for "Izover" can be assembled both from a wooden bursa and from a metal profile. The distance between the individual elements of the crate should be slightly less than the width of the insulation boards. This allows you to install them by surprise.

Of course, Isover, the technical characteristics of which we have described, when used as a heat or sound insulator, must be protected from moisture. In order to prevent it from getting wet, vapor and waterproofing films are used. When assembling a wall or roof pie, in this case, a certain order of installation of materials is observed. The vapor barrier is mounted from the inside. Due to the difference in temperature, the humidity in rooms and attics is usually higher than outside. Therefore, condensation forms on the walls and ceiling. The use of a vapor barrier prevents it from getting on the insulation. It is mounted outside. It protects the Izover from getting wet during rain or melting snow.

Additional fasteners when installing plates, as already mentioned, are not used. They are only needed when mounting the material on the ceiling. In order to completely exclude their loss, in this case, special dowels-"fungi" are used.

Since the material is capable, albeit in small quantities, of emitting substances harmful to human health, when installing it from inside the premises, it is necessary to carefully monitor the tightness of all seams of the fine finish.

Varieties

"Izover" - a heater, the technical characteristics of which we examined above - is classified into several popular types. In private housing construction, as already mentioned, the most commonly used material is "Classic", marked with the letter "K". It, in turn, is divided into:

• "Isover KL 34" - very soft plates with high heat-shielding properties, used for insulating surfaces without loads.
• "Isover KL 35" is a material with a slightly higher density. It is usually used for the same purposes as the 34th variety, that is, for walls and partitions.
• "Isover 37" is most often used to insulate floors, roofs and ceilings.
• "Izover KT" is usually used for warming basements or attics.

Such a type as Izover Classic Plus is also very popular. Its characteristics are exactly the same as those of the usual "Classic". These two varieties differ only in thickness. "Classic", as you can see from the table, is supplied in 50 mm mats. For "Classic Plus" this figure is 100 mm. There are other varieties of Isover material designed for a variety of purposes (Isover RKL, Isover OL, etc.).

Conclusion

Thus, the Isover insulation, the technical characteristics of which were discussed in detail in this article, is a very warm and high-quality material. It is possible to protect the house from the cold with its use as efficiently as possible. This, as well as not too high cost, explains its extraordinary popularity both among private traders and among small and large developers.

is one of the leading manufacturers of mineral wool fiberglass thermal insulation materials in the world. These heaters have established themselves as high-quality products with an optimal ratio of price and performance.

From this article you will learn what types of Izover thermal insulation exist, their characteristics, and how they differ from each other. We will also study the reviews and find out why these mineral wool heaters are better than similar products on the market.

1 Scope of thermal insulation Izover

Thermal insulation materials from the French company Isover, in addition to excellent insulating abilities, also have good noise-reducing properties, which greatly expands their scope.

3 Isover KL 34

Plate insulation, the thickness of which can be 5 or 10 centimeters. This material is intended for frame mounting, and does not require mandatory fixing with dowels. Model KL34, according to reviews, is characterized by high elasticity, which makes it possible to install it on any surface.

KL34 boards are delivered in double-pressed packages, after opening which, the material immediately takes its original shape. The thermal conductivity of Izover KL34 is 0.034 W / mk, the vapor permeability is 0.53 mg / mchPa.

Among the advantages of this model, it is worth highlighting the restoration after any deformation and resistance to shrinkage. The nominal compressibility of KL34 under a specific load of 2000 Pa is 60% as in , and the return after compressive loads is 98%.

KL34 corresponds to the flammability class NG - completely non-combustible material, and can be operated in the temperature range from -70 to +250 degrees. Moisture absorption KL34 when fully immersed in water for 72 hours is 5% of the total weight of the board, with partial immersion for 24 hours - 1%.

4 "Pitched Roof"

A material designed to insulate the inner surface of the roof of a house. Release form - plates with a thickness of 5 or 10 centimeters, a length of 117, and a width of 61 cm.

The advantages of Pitched Roof wool include high hydrophobicity - the material practically does not absorb moisture even when completely immersed in water for a long time, which allows it to be effectively used in difficult wet conditions in which other heaters would lose their thermal insulation abilities.

The technical characteristics of Izover "Pitched Roof" are as follows:

• thermal conductivity coefficient - 0.035 W / mK as y;
• steam conductivity coefficient - 0.55 mg / mchPa;
• Moisture absorption with partial immersion in 25 hours - 0.08 kg / m².

5 Isover KT37

Izover KT37 is a rolled thermal insulation material for insulating the internal parts of buildings made of concrete, brick, wood and aerated concrete. Consumer reviews indicate that it is perfect for insulating walls from the inside, attic or interfloor ceilings and lag floors.

KT37 belongs to the category of soft thermal insulation, the material has a density of 15 kg / m3, which does not allow the use of this material on surfaces that experience serious mechanical stress.

Compared with the initial volume of the roll, the packed KT37 is compressed almost 2 times, which greatly simplifies its transportation, the volume of one package is 0.16 cubic meters, after opening - 0.71 cubic meters.

The thermal conductivity of Izover KT37, as well as comparable with other heaters of this company, it is 37 W / mk, which makes even single-layer insulation with this mineral wool quite effective.

The thickness of the KT37 roll can be 50 or 100 mm, length - 630 cm, width - 60 cm. roll form insulation makes it possible to cover large surfaces much faster than it can be done with plate material. In terms of combustibility, the product is classified according to the European standard A1, which corresponds to our NG class (non-combustible material).

6 Isover KT40

Izover KT40 is a two-layer heat-insulating material produced in the form of a roll, designed for wall insulation. frame houses, installation in the middle of false walls and thermal insulation of free space inside hollow brick walls.

The thickness of the roll KT40 is 100 mm, while due to the two-layer design, the product can be divided into two rolls of 50 mm. The overall characteristics of KT40 are as follows: roll length - 700 cm, width - 61 cm, the area of ​​\u200b\u200bone package of insulation is 17.08 m².

In terms of thermal insulation properties, KT40 is somewhat inferior to the rest of the company's products; its thermal conductivity coefficient is 0.04 W / mk. The material has a high vapor permeability (about 0.5 Mg / MPa), which makes it the best option for wall insulation of wooden and frame houses.

According to the standards of combustibility GOST 30225 KT40 belongs to the class of non-combustible materials NG. This mineral wool is not intended for thermal insulation of surfaces with difficult wet conditions.

Moisture absorption of the material during partial immersion is about 15% of the total mass, as a result of which it is better to install an additional waterproofing layer when installing KT40.

On the market building materials Nowadays, such a wide variety of insulation materials is presented that it often even makes it difficult to choose. They differ in the base material and the form of manufacture, in the field of application and, of course, in the reputation of the manufacturer. The cost of heaters is often quite considerable, so the desire of consumers to give their money for a guaranteed quality product is quite understandable. And this means that it is best to stop the choice on the original products of well-known brands, among which "Isover" (in Russian transcription - "Isover") takes one of the leading places in terms of the effectiveness of thermal and sound insulation of buildings, in terms of its reliability and durability.

Isover insulation, the technical characteristics of which will be further discussed in this publication, is widely used in various fields. The materials of this brand are famous for the effective protection of residential, public, industrial, utility buildings and structures from cold, heat and external noise, and there is no doubt about their high quality.

A few words about the manufacturer of insulation "Isover"

The Isover manufacturer is a company that is part of the largest international association Saint Gobain, which manufactures a huge and comprehensive range of modern building materials. "Saint Gobain" brings together more than a hundred industrial companies and organizations involved in innovative developments in the construction industry. It's hard to even imagine, but the history of the emergence of this manufacturer dates back to XVII century– are there many companies in the world that would have already celebrated their 350th anniversary?!

Huge, centuries-old experience, the ability to properly organize the activities of all links, the constant independent development of innovative technologies and much more - all this is the basis for the fact that the manufacturer has become the undisputed leader in the manufacture of materials that allow you to create zones of the most comfortable living space.

"Saint Gobain" works in various directions. These are high-tech materials, ordinary flat glass and glass designed for special applications, building products, which include insulation, drywall and other gypsum-based products, building mixtures, tiles and facade cladding, acoustic panels for walls and ceilings, integrated drainage systems, plumbing and sewer pipes, and much more.

In addition to the Isover heaters discussed in this publication, which are produced in various modifications, the company also produces technical thermal and sound insulation materials under the Isotec and Isoroc brands.

The company has been operating in Russia for more than 20 years, producing various building materials, including mineral insulation based on basalt and fiberglass. The plant for their manufacture has been operating for more than 10 years in the city of Yegoryevsk (Moscow region), and in 2011, as part of the business expansion strategy, Saint Gobain acquired the Minvata plant in Chelyabinsk, which, after a radical re-equipment, now insulation is made on the basis of stone fibers.

All enterprises of this association successfully pass certification international standard environmental management, so heaters are considered environmentally friendly products. The company places its products in the same environmental group as linen and cotton, and they comply with European and international standards - EN 13162 - ISO 9001, as well as Saint Gobain's own extremely stringent standards.

The main types of thermal insulation "Isover"

So, the insulation materials of this manufacturer can be made from glass or basalt fibers. Such specific structures are obtained as a result of processing quartz sand, cullet or mineral rocks basalt group - their melting followed by drawing using the TEL fiberization technology. The resulting thinnest, almost microscopic threads with a thickness of 4 ÷ 5 microns and a length of 110 ÷ 150 microns are interconnected with special resins.

Mineral heaters "Isover" are produced in mats, which are then rolled up, and in slabs. Both of them can have different thicknesses and several linear dimensions, depending on their purpose and the recommended laying technology.

The main lines of this material are divided into types according to their areas of application in construction and universal. For example, the purpose of many heaters is clear from the name:

• "Isover Warm House Stove"
• "Isover Warm House"
• "Isover Warm Walls"
• "Isover Warm Roof"
• "Isover Sauna"

And the following types can be safely attributed to the materials of universal purpose:

• "Isover Optimal"
• "Isover Pro"
• "Isover Classic"
• "Isover Extra"

Each of the above heaters has its own characteristics that correspond to its area of ​​​​application. They will be discussed below.

In addition, "Isover" produces heat and sound insulators for the floor, interior partitions, ceilings and suspension systems, and wall materials are divided into those used for interior surfaces and for building facades.

There is one more criterion for the division of insulation materials "Isover" - by rigidity. The designation has an alphabetic symbolism applied to the package, and its decoding is given in the table below. This parameter is closely related to such characteristics as the density of the material, its thermal conductivity, and the degree of its compression in the original packaging (many types after opening the package increase significantly in the thickness of the slab or mat).

Table of division of heaters "Isover" according to the degree of rigidity:

Insulation marking	Average density, kg/m³	Thermal conductivity coefficient, W/m×°K	Compression ratio in factory packaging
CT-II– elastic mats in a roll	11÷13	0,041	1:4
CT– elastic mats in a roll	17	0,036	1:4
KL-A- flexible plate	17	0,041	1:1,5
KL- flexible plate	19	0,033	1:1,4
RKL– rigid board reinforced with fiberglass on both sides	60	0,030	No
RKL-A– windproof rigid plate (with tongue and groove connection)	60	0,030	No
RKL-EJ– a plate of increased rigidity (with tongue-and-groove connection)	95	0,031	No
SKL- semi-rigid plate	50	0,031	No
VKL- hard plate	130	0,032	No

General advantages and disadvantages of Isover heaters

Before proceeding to a detailed review of the technical characteristics of each type of Isover insulation, it makes sense to obtain information about their common features that are inherent in each of these products.

The positive characteristics of this material include the following qualities:

• Low thermal conductivity allows you to keep the heat generated by the heating units in the house for as long as possible, which means that less fuel will be spent on heating the building, and the owner will save a decent amount on paying for it.
• A high level of absorption of sound waves - this quality will reliably protect the house from external noise, and the rooms (when using the material in the construction of partitions) - from extraneous internal sounds. Good is achieved due to the structure of the material, since the air gap between the fibers is able to absorb vibrations. Any, in fact, from Isover heaters performs two functions at once: it thermally insulates the room and makes it as quiet as possible. But in addition, the manufacturer produces a material specifically designed specifically for noise protection.
• A high level of vapor permeability is one of the most important qualities for a heater. Such a material is also called "breathable", since it does not collect and does not retain moisture in its structure, which means that it will not create a favorable environment for the appearance of pathogenic microflora, the walls will not become damp. In addition, the ability to freely pass water vapor makes the insulation more durable in its direct functionality, since the waterlogged material has a sharp increase in thermal conductivity, and it becomes unable to provide proper thermal insulation. building structures.
• The incombustibility of Isover heat insulators makes them absolutely safe. The material is classified according to the NG combustibility scale, that is, according to the highest degree of resistance to fire, which means that it can be safely used in the construction of frame, block and log houses.
• "Isover" - slabs and mats are lightweight, so they can be used to insulate buildings in which excessive load on the supporting structures is unacceptable.
• The service life of the insulation, subject to the installation technology and operating rules, is 50 years or more.
• Isover heaters are treated with water repellents, that is, water-repellent compounds, so they have a fairly high moisture resistance.
• Affordable cost. Compared to other similar materials, Isover products have a price that is quite acceptable for a family with an average income.

True, the heat insulators of this manufacturer also have their own “minuses”, which for some may turn out to be significant, so they also need to be mentioned:

• Since the binders for basalt and glass fibers are usually phenol-formaldehyde resins, the material cannot be called absolutely clean from an environmental point of view. The fact is that over time, such compounds are able to begin to release into environment toxic fumes hazardous to human health.

Despite the fact that the manufacturer positions its products as absolutely “clean”, this still has to be treated with a certain amount of distrust. Binder resins have not yet been eliminated - and although formaldehyde emission is indeed reduced to a possible minimum, it is too early to talk about its complete absence.

It should also be noted here that almost all heaters of this type include precisely these binders. There are certain exceptions, but they are still so expensive in cost that not every homeowner can afford such thermal insulation.

• Despite the rather high moisture resistance, it is impossible to exclude waterlogging of the material in direct contact with water. Thus, a thermally insulating structure, for example, on a facade or on a roof, must necessarily provide for a reliable waterproofing layer.
• Since for the manufacture of any mineral wool, the finest fiber is used, which has relative rigidity, during installation, its smallest particles can get into Airways and eyes, as well as sticking into exposed areas of the skin. Therefore, this factor somewhat complicates the installation process due to the need to use protective equipment.

In addition, when insulating the house internally, mineral wool must be hermetically sealed with a dust-proof material so that fiber particles do not enter the air of residential premises.

• The manufacturer calls the advantage of heaters their incombustibility. However, it should be noted that some types of insulation (this applies to foil to a greater extent) are not non-combustible, but self-extinguishing, that is, they do not allow fire to spread. They can be used for buildings raised from any material, but at the same time observing the requirements for ensuring fire safety prescribed in SNiP 21-01-97.

Characteristics of thermal insulation materials "Isover" and recommendations for their use

Now, having familiarized ourselves with the information about the main "pluses" and "minuses" of Isover thermal and sound insulators, we can proceed to consider the detailed technical characteristics of each of them.

Prices for insulation "Isover"

Universal heaters "Isover"

The company produces not only narrow-purpose heaters, but also universal ones, which can be used for different building structures. Such materials include: "Optimal", "Profi", "Classic" and "Extra", as well as "Warm House Stove" and "Warm House".

Their technical and operational characteristics are given in the table:

	"Isover Optimal" (stove)	"Isover Profi" (mats in rolls)	"Isover Classic" (plates)	"Isover Classic" (mats in rolls)	"Isover Extra" (stove)

"Isover Optimal"

"Isover Optimal" is a universal material made of basalt fibers, which is used for insulation and soundproofing of all departments of the frame house structure, except for the foundation - this is the roof, ceilings, walls, partitions and floors along the logs.

In this option, in accordance with its name, we found the optimal combination of various qualities of the material:

- low thermal conductivity and excellent elasticity;

— simple installation that does not require additional fasteners;

— versatility of use;

• The first step is to install racks of timber with a step of 590 mm on the insulated surface or in the frame. Such a distance "in the light" will help the plates of heat and sound insulating material to securely fasten by surprise. The thickness of the timber racks or lag should be equal to the thickness of the heat insulator.

• The next step between the elements of the crate in one or two layers, insulation plates are installed, which must be pressed at the ends.
• If the wall of a frame house is insulated, then from the outside the insulation is tightened with a wind-waterproof membrane, and from the inside - with a vapor barrier film. These materials are stretched horizontally along the frame, starting from the bottom line of the wall, and fixed to the frame posts with staples and a stapler. The top sheet must be overlapped on the bottom sheet by 120÷150 mm, the joints of the membranes must be sealed by sticking a moisture-resistant adhesive tape on them.
• After that, a counter-lattice is fixed on the frame, on top of the film, on which the facing material will already be fixed. Thanks to this approach, between the heater and decorative trim a ventilation gap is created that contributes to the spontaneous removal of water vapor and the evaporation of condensate.
• The final stage is fixed on the frame structure, first from the side of the street, then from the inside of the house.

"Isover Pro"

"Isover Profi" is made of fiberglass in the form of mats rolled into rolls. This insulation is also universal, as it can be used for thermal insulation of roofs. various shapes, walls inside and outside, frame walls, attic ceilings, floors, suspended ceilings, as well as soundproofing of interior partitions.

This insulation has its own advantages that distinguish it from other Isover products:

• "Isover Profi" has one of the lowest thermal conductivity of all materials from this manufacturer.
• Due to the fact that special markings are applied to the mat, it is convenient to cut it. At the same time, even if it is insulated custom design, from the material there is a minimum of waste.
• The insulation is produced in different thicknesses - 150, 100 and 50 mm.
• This version of the heat insulator belongs to the "NG" group in terms of flammability.
• The manufacturer positions it as a material safe for human health.

Installation work using such material is easy and fast, since the roll on the package has the markings necessary for cutting. Therefore, the mats are cut to the desired width without unrolling the roll.

• The first step is to install racks with a standard step of 600 mm for the crate. The width of the roll is 1220 mm, it is cut in half and two strips 610 mm wide are obtained. Thanks to this size, the mats will be tightly installed between the posts or stacked between the lag by surprise.
• The cut roll is released from packaging, unrolled and installed between the frame elements. If the strip of insulation is not additionally cut into plates across, this will help to avoid the formation of cold bridges.
• The non-standard arrangement of the racks of the frame will complicate the installation. In this case, before cutting the mat, it is necessary to measure the distance between the frame elements, not forgetting to add 5 mm to the resulting distance for spreading on each side.
• If the attic structure is also insulated, then before installing the insulation, a windproof film is fixed on the outside of the roof.
• After the Isover insulation is installed, it must be tightened from the inside with a vapor barrier, the membrane of which is stretched horizontally, starting from the floor of the attic floor.

"Isover Classic"

Due to the fact that "Isover Classic" is universal, it can be used to insulate almost all building structures, excluding the plinth, foundation and surfaces that receive a high load. They are heat and sound insulated with frame structures - partitions and external walls, roofs and ceilings, ventilated facades and floors along logs.

"Isover Classic" is fiberglass insulation, produced in the form of mats in rolls and plates, with low rigidity. This means that it has a pronounced porous structure, which makes this material a good insulator.

However, this type of insulation does not have high strength characteristics, therefore not suitable for mounting under a screed and for finishing walls with plaster. If it is planned to be used for facade insulation, then only for materials such as siding, lining or plates fixed on the crate.

"Isover Classic" has the following distinctive features:

• A layer of this insulation with a thickness of 50 mm is equivalent in terms of heat saving to brickwork with a thickness of 950 mm.
• Using "Isover Classic" as a home insulation, you can reduce the cost of heating the building by 40÷45%.
• The material performs two functions at once - protecting the house from the cold and external noise.
• Installation of plates is carried out without the use of additional fasteners - it is installed at a distance between the elements of the crate or lags, adjoins them tightly, excluding the occurrence of cold bridges.

• If the floor is insulated along the lags, then it is recommended to fix them on glassine pre-spread on the base.
• The width of the "Isover Classic" slabs is 610 mm, and the mats are 1220 mm, so the distance between the floor joists or the racks of the crate should be 600 mm.
• The roll is cut across in the packaged form in half. The manufacturer prudently applies markings on the packaging, which will be easy to navigate when cutting the material.
• Then, the insulation boards are laid, and the mats are rolled out between the wooden structural elements. Due to the fact that the heat insulator has a width greater than the distance between the lags by 10 mm, it will fit snugly between them.
• The insulation must fill all the space between the timber. Only in this case, it is possible to achieve the desired effect of keeping warm and protecting from outside noise.
• If the insulation is installed in two layers, then the mats of the second layer must be laid or installed with an offset of their joints by 120 ÷ 150 mm relative to the first.
• The material is recommended to be used in combination with a wind and hydroprotective film and a vapor barrier membrane.

"Isover Extra"

"Isover Extra" is a fiberglass insulation in the form of plates with increased elasticity with a 3D effect, which allows the material to straighten out after it is compressed, filling all free space between timber or metal profiles in drywall systems. In addition, the plates fit snugly against the wall when insulating vertical surfaces, and are also tightly connected to each other at the joints, which completely eliminates the appearance of cold bridges.

Thanks to these features, Isover Extra insulation is universal and is used for thermal insulation of walls from the inside of rooms, facade surfaces for cladding them with bricks, siding, clapboard and decorative plates, roofs of various modifications.

"Isover Extra" has a thermal conductivity coefficient of 0.034, which makes it one of the most effective materials from the heaters presented by "Isover" in terms of heat saving - its use reduces heat loss to a minimum.

Installation of this type of insulation is carried out according to the manufacturer's recommendations given above, taking into account the width of the plates and the distance between the frame elements. The only thing I would like to add is that, thanks to the 3D effect, there is no need to level the surface to be insulated for the installation of Isover Extra - due to expansion, it will fit snugly against it.

"Isover Warm House Stove" and "Isover Warm House"

These two thermal insulation materials can also be called universal, as they are suitable for installation in most construction sites. Their main characteristics, slightly different from each other, are shown in the table:

The main parameters of the insulation	"Isover Warm House"	"Isover Warm House Stove"

"Isover Warm House Stove" and "Isover Warm House", as can be seen from the table above, have the same physical and operational characteristics and differ only in linear dimensions and volume. Both materials are made from fiberglass obtained from the processing of a specially selected mixture of limestone, sand and soda. However, plates are more convenient to use for insulation in one area, and mats in another.

• "Isover Warm House Stove", as the name implies, it is produced in slabs, which are more convenient to use for thermal insulation of vertical surfaces, both from the inside and outside, as well as to insulate them

• "Isover Warm House" It is produced in the form of mats and goes on sale in rolls. This modification of the insulation is perfect for laying on horizontal surfaces. So, they isolate the interfloor ceilings, they will insulate the floors well above the cold basement, but they are mounted only between the logs, and this material is not suitable for screeding.

Having dealt with the universal insulation "Isover", you can proceed to consider those that are designed for specific areas of the structure.

Isover mineral wool for specific applications

For individual sections of thermal insulation of buildings, the manufacturer has developed several types of specific materials. Therefore, to make it easier to understand their models, they should be combined into groups.

Facade insulation for further plastering

To insulate this part of the building, several Isover materials are used - these are Facade-Master, Plaster Facade, Facade and Facade-Light. Each of them is designed for specific surfaces, so their characteristics differ from each other:

The main parameters of the insulation	"Isover Facade-Master" (plate)	"Isover Stucco Facade" (slab)	"Isover Facade" (plate)	"Isover Facade-Light" (plate)
Thermal conductivity coefficient, at 10˚С, W/m×˚С	0.036÷0.040	0.038÷0.040	0.037÷0.042	0,034

• - this is a heater made of basalt fiber (stone wool), it goes on sale in slabs of different thicknesses. The material is intended for insulation of the facade of residential buildings up to 16 meters high, under thin-layer plaster.

Prices for plaster "Facade-master"

facade master

• produced in glass fiber slabs and is an innovative material for thermal insulation of a building from the outside. This material has a more affordable price than the previous one, but is also intended for installation under the finish plaster mortars which will be applied to their surface in a thin layer.

• produced in the form of slabs of basalt fiber, and is intended for facade insulation. The material is usually laid with the expectation of subsequent finishing with decorative plaster.

• - this version of fiberglass facade insulation is used for low-rise buildings and is installed under the finish with a thin plaster layer. The material is well suited for warming country houses and cottages. Insulation is different high strength and rigidity, however, has a lower weight compared to heaters of a similar purpose.

• Work on the insulation of the facade using the "wet facade" technology, that is, with subsequent plastering, must be carried out at a temperature of at least +5 degrees, having previously protected the walls from possible direct ingress of water. Usually, a temporary structure made of timber or metal profiles is installed for this, which serves as a frame for a plastic film.
• Installation of insulation starts from the bottom of the wall. Fix the plates on a pre-primed and dried wall, on an adhesive solution. The solution must be applied to the surface of the slab so that contact is ensured over at least 40% of the total area of ​​the slab.

• The plates are glued to the wall, pressing tightly against each other. If between them, due to the incorrect "geometry" of the walls, gaps of more than 2 mm are formed, they must be filled with strips of the same insulation.

• After the glue dries, the insulation is additionally fixed on the wall with special fasteners, the so-called "fungi".

• The next step is to cover the insulated surface of the wall with a thin layer of adhesive, so that the relief of the plates can be seen through it. Usually the same glue is used as when installing the plates. After that, a thicker layer is applied, about 3 ÷ 5 mm, and it is recommended to walk over it with a notched trowel with a low comb.

• After that, without a pause, a reinforcing fiberglass mesh is fixed on the prepared surface, which is sunk into the distributed solution with a spatula (trowel). The mesh must be completely immersed in the solution.
• Next, proceed to the application of a thin (about 3 ÷ 4 mm) base plaster layer. This may be a special composition designed specifically for the “wet facade”, or again the same assembly adhesive for mineral wool. This layer is leveled, smoothed, and when ready, it is primed with a special compound for a specific type of decorative plaster.
• After the base plaster layer dries, decorative plaster can be applied on it.

Wall insulation materials inside and out

The next line of insulation "Isover" includes products designed for thermal and sound insulation of walls both from the inside and outside. These include universal materials such as "Isover Profi" and "Isover Classic Slab", the characteristics of which are described above, as well as "Isover Warm Walls", "Isover Warm and Quiet Wall" and "Isover Standard", the parameters of which are presented in the following table:

The main parameters of the insulation	"Isover Warm Walls" (stove)	"Isover Warm and Quiet Wall" (mats in rolls)	"Isover Warm and Quiet Wall" (plates)	"Isover Warm and Quiet Wall Plus" (plates)	"Isover Standard" (plates)

"Isover Standard"

"Isover Standard" - these are plates made from basalt fibers, which are used in multilayer insulating structures, in which a block house, siding, lining, facing brick, and other similar materials act as a decorative finish. In addition, "Standard" slabs are suitable for thermal insulation of frame structures, as well as for attic and pitched roof.

• The material has an average density, therefore it is not suitable for installation under plastering walls.
• The good elasticity of the insulation ensures its snug fit to the surfaces of the walls and the frame structure.
• Increased tensile and strength parameters provide reliable fixation of the plates with the help of special clamping fasteners - "fungi".

"Isover Warm Walls"

"Isover Warm Walls" are heat and sound insulating boards made of glass fibers, reinforced with a water-repellent treatment.

This version of the insulation is used for thermal insulation of walls from the inside of the building and for outdoor installation under sheathing with siding, decorative plates, clapboard or facing bricks, as well as for installation in frame structures. In addition, the material is suitable for insulating roofs of various configurations, as well as loggias and balconies.

• Insulation plates are sufficiently resilient and elastic, so they hold well between the racks of the frame, do not slip or break during installation.
• Increased moisture resistance allows the use of material for insulation of roofs and balconies.

"Isover Warm and Quiet Wall"

"Isover Warm and Quiet Wall" is made of fiberglass in the form of plates and mats. Due to its porous structure, the material is able to perform two functions, which are reflected in its name.

This version of "Isover" is used for internal and external wall insulation, as well as for frame buildings.

• "Isover Heat and Quiet Walls" has an increased vapor permeability parameter compared to other heaters, which allows it to "breathe". Thanks to this quality, a favorable microclimate is created in the premises of the house.
• The materials have high elasticity, so they quickly straighten out in the frame, filling all the free space.
• When installing slabs or mats in any frame, they do not need to be additionally fixed, since they are perfectly held due to the expansion during self-expansion.

"Isover Warm and Quiet Wall Plus"

This version of wall insulation is produced in fiberglass slabs and has characteristics similar to the materials presented above. But its distinctive feature is a lower thermal conductivity and an increased sound insulation index.

"Isover Heat and Quiet Wall Plus" is designed to insulate walls from the inside of the building, as well as from the outside under the decorative layer of siding, slabs, lining or facing bricks. In addition, using additional protective materials, such as wind-waterproofing and vapor barrier membranes, these boards can also be used to insulate frame structures.

Recommendations for internal wall insulation from the manufacturer

Work on the installation of insulation mats or plates on the walls between wooden racks or metal profiles is quite simple, with the correct marking and installation of the elements of the crate.

• The first step is to fix the crate on the marked wall. Racks are installed at a distance from each other, depending on the width of the insulation material. So, if the width of the plate is 600 mm, then the racks must be fixed in increments of 590 mm.
• Further, insulation material is installed between the fixed racks. It can be mounted in one or two layers, depending on the required thickness.
• If a metal profile is used for the frame, it may be necessary to additionally fix the plates on the wall with dish-shaped dowels - “fungi”. When installing a crate from a bar, there is usually no need for additional fixation of the insulation, since it is securely held due to self-expansion.

• After all the insulation is installed in its place, it must be tightened from the side of the room with a vapor barrier membrane, which will additionally become a layer that will delay the spread of dust, and small particles from mineral wool fibers will not enter the airspace of the premises. The membrane sheets are stretched horizontally, starting from the floor, each subsequent strip is overlapped by 120 ÷ 150 mm on the bottom, and their joints are sealed with adhesive tape.
• Further, drywall plates, one of the types of lining or decorative plates are fixed to the frame elements.

When installing insulation using this technology on the outer surfaces of the walls, work is carried out the same way, with some exceptions. For example, instead of a vapor barrier, a wind-damp-proof diffuse membrane is stretched over the insulation (which passes water vapor well), and on top of it, counter-battens are fixed to the racks, which will create a ventilated gap between the insulation and the decorative sheathing. Thus, moisture will freely evaporate into the atmosphere.

Isover materials for roof insulation

To insulate the roof, Isover also provided several heat-insulating materials, and some of them have already been described above - these are the Optimal and Profi station wagons. In addition to them, there are also highly specialized heaters "Isover Warm Roof" and "Isover Pitched Roofs and Attics", the characteristics of which will be discussed further.

The main parameters of the insulation	"Isover Warm Roof" (mats in rolls)	"Isover Pitched Roofs" (slabs)

"Isover Warm Roof" and "Isover Pitched Roofs"

Both materials are designed to insulate roof slopes. different configurations, but have different characteristics, in the form of release, linear dimensions and material of manufacture. They are united by the fact that heaters for this area of ​​application undergo a special treatment using the AquaProtect technology, which provides products with increased moisture resistance.

• "Isover Warm Roof" is made of fiberglass in the form of mats rolled into rolls. They go on sale in a polyethylene package, on which markings are applied for the convenience of cutting the material along its width.

• "Isover Pitched Roofs" - made from basalt fibers in the form of slabs, which are pressed and also packaged in polyethylene.

These materials are suitable for thermal insulation of pitched and mansard roofs, and also, by the way, for wall surfaces from the inside and outside under cladding with decorative panels and facing bricks.

The procedure for installing insulation in the roof truss system is described in the "Isover Profi" section.

Floor insulation and soundproofing

In order to insulate the floors with high quality, the manufacturing company has developed two types of special materials - Isover Floor and Isover Floating Floor, which have different technical and operational characteristics:

The main parameters of the insulation	"Isover Floor" (plates)	"Isover Floating Floor" (slabs)
Thermal conductivity coefficient, at 10˚С, W/m×˚С	0,036	0,033
Airborne sound insulation index Rw (dB)	32÷36	37

Width, mm	600	1190
Length, mm	1200	1380
The volume of insulation in the package, m³	0,173; 0,216; 0,216	0,197; 0,296; 0,296; 0,328; 0,328
Insulation area in the package, depending on the thickness, m²	5,76; 4,32; 4,32	9,85; 14,78; 9,85; 8,21; 6,57
The number of mats in the package, depending on the thickness, pcs.	8,0; 6,0; 6,0	6,0; 9,0; 6,0; 5,0; 4,0

These materials have a common purpose, and therefore similar characteristics. The manufacturer in their development has achieved the optimal combination of damping properties and mechanical characteristics. Both types of insulation are easy to install, but their installation technologies differ from each other.

Products not only insulate surfaces, but also significantly reduce the noise coming from the insulated room to the one below the floor and vice versa.

• "Isover Flor"- These are plates made of basalt fiber with increased rigidity. They are used for arranging a floating floor, as well as a floor along logs. The construction of a floating floor provides greater efficiency in creating a warm and quiet floor, since the insulation in it completely covers the entire surface. The material is adapted to high loads, so it may well be laid under a concrete screed.

• "Isover Floating Floor"- this version of the slabs made of glass fibers is intended to create a "floating" floor - a concrete screed that is not connected to the walls and the base. For a tighter connection of the plates to each other, the manufacturer, by order of consumers, can produce products with a tenon-groove connection. However, jointed slabs can only be used on a perfectly leveled surface.

Products have high strength characteristics due to the technology of vertical arrangement of fibers.

"Floating" refers to the design of the floor, which is not fixed to the base, for example, to the floor slab.

If it is supposed to make a “wet” cement-sand screed covering the insulation, then the plates laid on the base must be covered with a layer of waterproofing. This material is intended to protect the insulation from the penetration of moisture from the concrete solution. Waterproofing sheets are overlapped by 200÷250 mm. Waterproofing is also provided between the base and the insulation layer - to prevent capillary penetration of moisture into the material.

In addition, when arranging any, before installing the insulation, it is necessary to install a damper tape around the perimeter of the room or narrow strips cut from the insulation, 10 ÷ 12 mm thick, and a height that will exceed the level of the screed by 120 ÷ 150 mm.

After the screed has hardened, it will be easy to cut off the excess damper strip. This element of the “pie” structure will enhance sound insulation, since the screed will not adjoin the walls and will not directly transmit noise vibrations. In addition, such a damper will keep the screed intact during linear expansions caused by temperature changes.

Isover materials for building soundproofing

To protect the house from external and internal noise, the company produces two types of specific material - Isover Quiet House and Isover Sound Protection. However, in addition to them, for this purpose, the above-mentioned universal heaters "Classic" and "Profi" can be used, which have characteristics that are quite suitable for this purpose.

The main parameters of the insulation	"Isover Quiet House" (plates)	"Isover SoundProtection" (plates)
Thermal conductivity coefficient, at 10˚С, W/m×˚С	0,038	0.038÷0.044

The number of mats in the package, depending on the thickness, pcs.	14,0	14,0; 7,0; 20,0; 16,0; 10,0

• "Isover Quiethouse»

"Isover Quiet House" - this heat and sound insulator made of fiberglass, goes on sale in polyethylene packages. The material has a high noise absorption index, therefore it is an excellent tool for soundproofing walls and interior partitions.

In addition, the slabs are laid on horizontal surfaces - between the floor joists, attic floor beams, in the space between the suspended ceiling and the floor slab, etc. Their installation will make the rooms not only quiet, but also warm, since the material performs two functions at once.

• "Isover SoundProtection"

"Isover ZvukoZaschita" are slabs molded from basalt fiber, which have a pronounced elasticity. Due to this quality, they are easy to mount in a frame crate, installed in the form of a partition or fixed to the wall.

Soundproof boards can be used in combination with other insulation materials, installing them in two layers. This design will be especially effective for frame partitions.

This material is also perfect for attic floors, since the sound insulator layer will not only prevent extraneous sounds from entering the house, but also retain the accumulated heat, preventing it from escaping through the ceiling.

Most often, walls and partitions insulated with slabs are sheathed, as it is best suited for such structures.

• The slabs should fit snugly against each other or against the elements of the crate, since even small gaps can significantly reduce the level of sound insulation.
• Best for insulated wall cladding drywall sheets- it also absorbs sound waves well, resonates much less compared to wood-based sheets - plywood, fiberboard, chipboard, OSB, etc.
• Before sheathing with drywall, mineral wool must be covered with a material that does not let dust into the living quarters along with microscopic fragments of fibers. At the same time, such a membrane should act as a vapor barrier.
• If metal profiles are used for the frame, it is recommended to stick a vibration-proof tape on their outer surface before fixing the drywall, which will also help reduce the noise level.
• The gaps allowed between the plasterboard sheets will reduce the soundproofing effect, therefore, during installation, care should be taken that they are not more than 2 ÷ 3 mm. If this was not achieved, it is best to use sealants on silicone and acrylic base, as they also have a soundproofing effect, do not crumble and adhere securely to the surface.

Materials for thermal insulation in the bath and sauna

For the insulation of saunas and baths in the range of materials from this manufacturer, you can find a specific offer - these are mats rolled into a roll with the characteristic name "Isover Sauna".

This material is made of fiberglass and has a foil coating on the front side. The main characteristics of "Isover Sauna" are presented in the table:

The main parameters of the insulation	"Isover Sauna", mats in rolls
Thermal conductivity coefficient, at 10˚С, W/m×˚С	0,041
Airborne sound insulation index Rw (dB)	54
Moisture absorption at partial immersion in 24 hours, kg/m², no more	1
Vapor permeability mg/m×h×Pa	vapor-tight
Insulation density, kg/m³	30
Flammability group	G1 based on NG
Thickness, mm	50;100
Width, mm	1200
Length, mm	12500; 6250
The volume of insulation in the package, m³	0,75
Insulation area in the package, depending on the thickness, m²	15,0; 7,5
The number of mats in the package, depending on the thickness, pcs.	1,0

The following points can be attributed to the features of this heat-insulating material:

• The mats consist of two layers: the main one, made of mineral wool based on glass fiber, and the outer one, made of foil. At the same time, mineral wool is characterized as a non-combustible material, and the foil coating belongs to the G1 combustibility class, as it withstands surface temperatures up to 100 degrees, mostly due to the adhesive layer that holds the foil. With higher heating, this layer loses its elasticity and, under direct exposure to a flame, can ignite, although being self-extinguishing. To prevent this from happening, as well as to give the walls a decorative effect, they are usually sheathed with wooden clapboard.
• "Isover Sauna" takes on two functions: it is a good heat insulator and at the same time - a vapor barrier that protects the mineral layer from abundant evaporation, which are an integral part of a bath or sauna.
• The foil layer has the ability to reflect heat from the walls back into the room, which significantly increases heat saving, which is so important for bath conditions.

To understand the installation process, you can consider an approximate scheme for installing materials:

• Wall log cabin(there may well be any other wall of the bath).
• Timber framing. In this case, it is installed horizontally, but this is not important.
• Insulation "Isover Sauna".
• Spacer strips that create an air gap.
• The interior lining of the premises is made of natural lining.

Installation of "Isover Sauna" on the walls is not very different from the installation of conventional heaters, except for some nuances:

• The material is mounted between the racks in a spacer, with the foil side inside the room.
• The joints of the heat insulator plates with the guides and between themselves, as well as the remaining open front part of the guides, must be sealed with foil adhesive tape.

• Mats need to be cut only with a very sharp knife, otherwise the cuts will turn out uneven and when installing insulation between the racks, unacceptable gaps are formed.
• On top of the insulation, counter-lattices perpendicular to the guide rails are installed. They will additionally press the insulation against the wall, create a ventilation gap between the foil surface and the decorative sheathing, and become the basis for attaching the cladding. The thickness of the rails must be at least 25÷30 mm.
• The final stage is the lining of the wall with clapboard, which is fixed to the rails of the counter-lattice.

And what is the thickness of the material "Isover" is necessary for effective thermal insulation?

We hope that after getting acquainted with the range of Isover heaters, the purpose and characteristics of each type, the interested reader will be able to choose the best material for their needs. But here's another question - how thick should the insulation be in order for it to really fulfill its role, so that a comfortable microclimate is maintained in the premises?

To determine this, you will need to make some thermotechnical calculations. Usually they are carried out by socialists, but for a private developer, a somewhat simplified algorithm for determining the thickness of thermal insulation is enough. Let's try - you will see that everything is not so difficult.

The calculation is based on the fact that any building structure of a residential building must have a certain parameter - heat transfer resistance. This value (R) is expressed in m² × ° C / W, and the larger it is, the higher the thermal insulation capacity of the structure.

Specialists in the field of construction and heat engineering carried out the necessary calculations, on the basis of which normalized values ​​of thermal resistance were established for various regions of the country, in accordance with their climatic features. This suggests that in order to maintain an optimal microclimate in residential premises at any time of the year, it is required that the heat transfer resistance of building structures be at least not lower than normalized.

The corresponding tables of normalized values ​​are in the SNiP, but it will be more convenient to use the diagram below.

There is a special formula that shows the relationship between the thermal conductivity of any material, the thickness of its layer, and the resulting resistance to heat transfer.

R=h/λ

R is the required resistance to heat transfer;

h is the thickness of a specific layer;

λ - tabular value of the coefficient of thermal conductivity of the material from which the calculated layer is made.

• Thus, knowing, for example, the thickness of the wall requiring insulation, and the material of its manufacture, it is easy to find what thermal resistance it provides.
• The same calculations are made for other layers of the structure, if they affect the overall insulation of the wall. After a layer-by-layer calculation, the values ​​are summarized.
• Then the total value must be compared with the normalized value established for your region. You will get a difference (usually very impressive), which the insulation material should make up for.
• Well, knowing the thermal conductivity of the selected insulation, it is easy to determine the required thickness by the formula.

“In words”, perhaps, it will seem difficult to someone, but with our online calculator, which takes into account the necessary tabular values ​​​​and entered desired dependencies, the calculation will not be difficult.

The building materials market is replete with a variety of insulation and soundproofing materials for buildings. As a rule, the main difference between them is the form of manufacture and the composition of the base, but the country of origin, the reputation of the manufacturer and the possibilities of application also play a significant role.

Heaters usually cost a significant amount, so in order not to get into a mess, you need to rely on a guaranteed quality product, for example, products from Isover. According to experts and customer reviews, it occupies a leading position in such characteristics as service life, reliability and efficiency.

Peculiarities

Isover insulation is used in both residential buildings as well as in public institutions and industrial buildings. This product is produced and sold by a company that is part of the international association Saint Gobain- one of the leaders in the building materials market, which arose more than 350 years ago. Saint Gobain is known for its innovative designs, applications modern technologies and the high quality of their products. All of the above points also apply to Isover heaters, produced in various modifications.

Isover products share many of the pros and cons of mineral wool as they exhibit similar properties. On the market, they are sold in the format of plates, rigid and semi-rigid, and mats, rolled up in rolls according to their own patented technologies in 1981 and 1957. This insulation is used for processing roofs, ceilings, facades, ceilings, floors and walls, as well as ventilation pipes. Isover is based on glass fibers. Their length is from 100 to 150 microns, and the thickness is from 4 to 5 microns. This material is resilient and resistant to stress.

Isover insulation is tear-resistant, which means it can be placed on complex structures. For example, these include pipes, elements production lines, industrial equipment and others.

When using Isover as a heater or sound insulator, it must be protected from moisture.

Usually, vapor barrier and waterproofing films are used for this. It is customary to install a vapor barrier from the inside of the house to protect it from condensation. waterproofing film placed outside, saving from rain and melting snow. As a rule, Isover is mounted without the use of fasteners, the only exception may be the insulation of the ceiling - in this case, dowels-"fungi" are used.

Under the "cap" of the brand, a lot of heaters are produced, which have different purposes and perform various functions. They are divided into two groups: for industrial and domestic use. In private housing construction, the Classic material, marked with the letter K, is most often used.

The price of Isover insulation may vary in different regions of our country. Usually the average figure varies from 120 to 160 rubles per square meter. In some areas, it is more profitable to purchase it in packages, and somewhere in cubic meters.

The subtleties of manufacturing

Saint Gobain has been operating on the Russian market for more than 20 years and is engaged in the production of materials at two factories: in Yegorievsk and Chelyabinsk. All enterprises are obliged to undergo certification of the international standard of environmental management, which makes Isover insulation an environmentally friendly product that is in its own right. environmental performance on par with cotton and linen.

Different types of Isover contain both glass and basalt fibers. This structure is the result of processing glass cullet, quartz sand or mineral rocks of the basalt group.

• It is in Isover that mineral raw materials are used. Its constituents are melted and drawn into fibers following the TEL technology. As a result, very thin threads are obtained, which are interconnected using a special composition of resins.

• The composition of cullet, limestone, quartz sand and other minerals is carefully mixed beforehand.
• To obtain a homogeneous fluid mass, the resulting mixture must be melted at a temperature of 1300 degrees.
• After that, the "liquid glass" falls on a rapidly moving bowl, in the walls of which holes are made. Thanks to physics, the mass flows outward in the form of threads.
• In the next step, the fibers must be mixed with a polymer adhesive that has a yellow tint. The resulting substance enters the furnace, where it is blown with hot air and moves between steel shafts.
• The glue sets, the layer is leveled and glass wool is formed. It remains only to send it under the circular saws in order to cut it into fragments of the required size.

When buying Isover, you can see the quality certificates. When the material is produced under license, the seller provides documents confirming the EN 13162 and ISO 9001 standards. These become a guarantee that the Isover is made of safe materials and is not prohibited from being used indoors.

Varieties

Exist different kinds insulation, depending on whether they are sold in a roll format or in slabs. Both varieties can have different sizes, and different thicknesses, and different laying technology.

Heaters are subdivided and depending on industries of application. They are universal or suitable for individual areas– walls, roofs or saunas. Often the purpose of the insulation is encrypted in its name. In addition, it is worth adding that the materials are divided into those used indoors and on the facades of buildings.

It is also worth adding that Isover are divided according to the stiffness of the material. This parameter, related to the characteristics of GOST, is indicated on the package and is closely related to the density, compression ratio in the package and thermal insulation properties.

Pros and cons

All Isover heaters have similar positive and negative characteristics. If we talk about the pros, then the following are distinguished:

• The material has low thermal conductivity. This means that the heat "lingers" in the room for a long time, so it is possible to spend less on heating, thereby saving significant amounts.
• The insulation demonstrates a high ability to absorb noise due to the presence of an air gap between the fibers, which absorbs vibrations. The room becomes as quiet as possible, protected from external noise.
• Isover has a high level of vapor permeability, that is, the material breathes. It does not retain moisture and the walls do not begin to dampen. In addition, the dryness of the material increases its service life, because the presence of moisture negatively affects the thermal conductivity.

• Thermal insulators are completely non-flammable. According to the flammability scale, they received the highest rating, that is, the best resistance to fire. As a result, Isover can be used to build wooden buildings.
• Plates and mats are lightweight and can be used in buildings that do not tolerate excessive load.
• Service life can reach 50 years.
• Heaters are treated with compounds that increase moisture resistance.
• The material is easy to transport and store. The manufacturer compresses Isover 5-6 times when packing, and then it completely returns to its shape.
• There are product lines with different technical characteristics, designed for different areas of construction.

• Isover is highly resilient. The insulation is superior to other mineral wools in this indicator due to the special TEL technology, according to which it is produced.
• 5 centimeters of mineral wool are equal in thermal conductivity to 1 meter of brickwork.
• Isover is resistant to biological and chemical attack.
• Isover is quite affordable, especially when compared to other alternatives.
• The material demonstrates high rates of density and rigidity, which allows it to be mounted without additional fasteners.

However, there are still a few downsides:

• A relatively complex installation process, during which it is necessary to additionally protect the respiratory system and eyes.
• The need to lay an additional layer of waterproofing during construction. Otherwise, it will absorb moisture, which will disrupt thermal insulation characteristics. In winter, mineral wool can even freeze, which is why it is important to leave a ventilation gap.
• Some types still do not belong to non-combustible, but to self-extinguishing - in this case, you will additionally have to comply with fire safety requirements.
• The soft structure of cotton wool limits the scope.
• The only negative for industrial enterprises is that when the temperature rises to 260 degrees Isover loses its properties. Namely, there such a temperature is quite possible.

Specifications

Isover is produced using a special patented TEL technology and has excellent technical characteristics.

• Coefficient of thermal conductivity very small - only 0.041 watts per meter / Kelvin. A big plus is the fact that its value does not increase over time. Insulation retains heat and retains air.
• As for soundproofing, the indicators for different models differ, but are always at a high level. This means that any kind of Isover will somehow protect the room from external noise. All this is ensured by the air gap between the glass fibers.
• With regard to combustibility, then Isover varieties are either non-combustible or low-flammable and self-extinguishing. This value is determined by the relevant GOST and means that the use of almost any Isover is absolutely safe.
• Vapor resistance of this insulation ranges from 0.50 to 0.55 mg / mchPa. When the insulation is moistened by at least 1%, the thermal insulation will immediately deteriorate by as much as 10%. To prevent this from happening, it is necessary to leave a gap of at least 2 centimeters between the wall and the insulation for ventilation. Glass fibers will return moisture and thus maintain thermal insulation.

• Isover can serve up to 50 years and for a rather impressive period not to lose their thermal insulation qualities.
• In addition, the heater contains water-repellent components which makes it inaccessible to mold.
• It is also important that in fiberglass material bugs will not be able to settle and other pests. In addition, the density of Isover is approximately 13 kilograms per cubic meter.
• Isover considered environmentally friendly insulation and absolutely safe for human health.
• It is much lighter than the competition, therefore, it can be used in rooms made of fragile materials or in which it is forbidden to create excessive loads. The thickness of a single-layer Isover can be either 5 or 10 centimeters, and in a two-layer Isover, each layer is limited to 5 centimeters. Slabs are usually cut meter by meter in size, but there are exceptions. The area of ​​one roll varies from 16 to 20 square meters. Its standard width is 1.2 meters, and the length can vary from 7 to 14 meters.

Isover produces not only universal heaters, but also narrowly focused actions that are responsible for specific elements of the building. They differ in size, functions and technical properties.

Isover can be produced for light thermal insulation (wall and roof insulation), general building insulation (soft slabs for frame structures, medium hard slabs, mats without fasteners and mats with foil on one side) and special purposes (for pitched roofs).

Isover has a special marking where:

• KL are plates;
• KT - mats;
• OL-E - mats of special rigidity.

The numbers show the class of thermal conductivity.

The packaging also indicates where one or another type of insulation can be used.

• "Isover Optimal" It is considered a universal material that is used to process ceilings, walls, partitions, roofs and floors along logs - that is, all parts of the house, except for the foundation. The material has low thermal conductivity and retains heat in the house, it is elastic and non-combustible. Installation is very easy, does not require additional fasteners, and, given the versatility, all of the above points make "Optimal" one of the most popular representatives of Isover.
• "Isover Pro" It is also a versatile insulator. It is sold in the form of rolled mats and is used for roofs, walls, ceilings, ceilings and partitions. "Profi" has one of the lowest thermal conductivity and is very convenient to cut. The insulation can be 50, 100 and 150 mm thick. Just like "Optimal", "Profi" belongs to the NG class in terms of combustibility - that is, it is absolutely safe in a fire situation.

• "Isover Classic" is chosen for thermal and sound insulation of almost all parts of the house, except for those that experience the greatest load. The "exceptions" include the basement and foundation. The material is sold both in rolls and plates and has low rigidity. The porous structure makes it an excellent insulator. However this species does not differ in strength and durability, which means it is not suitable for installation under a screed and for finishing walls under plaster. If, nevertheless, there is a desire to use it for facade insulation, then only in combination with siding, clapboard or facade panels fixed on the crate. "Classic" insulates the house very well and allows you to reduce heating costs by almost half. In addition, it is a good sound insulator and protects the building from unnecessary noise.

• "Isover Warm House-Stove" and "Isover Warm House" used in the installation of most parts of the house. They have almost the same technical characteristics, with the exception of volume and linear dimensions. However, it is customary to use plates in one area, and mats in another. "Warm House-Stove" is selected for the insulation of vertical surfaces, inside and outside the house, as well as frame buildings. "Warm House", which is sold in the form of rolls of mats, is used to insulate interfloor ceilings and the floor above the basement (installation takes place between the lags).
• "Isover Extra" It is made in the form of plates with increased elasticity and 3D effect. The latter means that after compression, the material expands and occupies all the free space between the surfaces that require insulation. The plates are tightly connected to each other and just as tightly adjoin to the surfaces. "Extra" is also universal, but is usually used for wall insulation indoors. It is worth adding that it can also be used for thermal insulation of facades in the case of subsequent cladding with bricks, clapboard, siding or panels, and for roofs. "Isover Extra" is considered one of the most effective heat preservation materials.

• "Isover P-34" It is produced in the form of plates, the thickness of which can be 5 or 10 centimeters. They are mounted on a frame and are used to insulate ventilated parts of the house - facade or multilayer masonry. It is possible to insulate both vertical, and horizontal, and inclined surfaces, since the model is very elastic. "P-34" is easily restored after deformations and is resistant to shrinkage. It is completely non-combustible material.
• "Isover Frame P-37" used for insulation of floors between floors, roof slopes and walls. It is important to consider that the material must fit snugly against the surface. "Isover KT37" also adheres tightly to the surface and is used for insulation of floors, partitions, attics and roofs.

• Isover KT40 refers to two-layer materials and is sold in the form of rolls. It is used exclusively on surfaces located horizontally, that is, for ceilings and floors. In case of insufficient depth of the cavity, the material is divided into two separate layers of 5 centimeters. The material has a high vapor permeability and belongs to non-combustible materials. Unfortunately, it cannot be used on surfaces with difficult wet conditions.
• Isover Styrofoam 300A requires mandatory fasteners and is available in the form of plates. The material has increased moisture resistance and thermal insulation due to the presence of extruded polystyrene foam in the composition. Such insulation is used to treat walls inside and outside the premises, floors and flat roofs. It is possible to apply plaster on top.

• "Isover Ventiterm" has a somewhat unusual scope. It is used for ventilated facades, pipes, plumbing, as well as to protect precision instruments from the cold. You can work with it both with and without fasteners. Such a heater is produced in the form of plates. Its technical characteristics are quite serious, especially in terms of strength - an order of magnitude better than that of ordinary mineral wool.
• "Isover Frame House" It is used to insulate walls from the outside and from the inside, pitched roofs and attics, as well as ceilings and partitions. In general, it is suitable for improving any frame structures in the house. The elasticity of the material helps to keep its shape during operation and installation, and the fibers stone wool provide additional noise protection.

Roofing

For roof insulation, some universal varieties of Isover are used, for example, "Optimal" and "Pro", as well as highly specialized "Isover warm roof"and" Isover Pitched roofs and attics ". Both materials are designed for the same purpose, but have different characteristics: they differ in the form of release, linear dimensions and the material used. They also undergo a special treatment that gives the products increased moisture resistance.

• "Warm Roof" produced in the form of mats rolled up. They are sold in plastic packaging with markings that allow you to cut the material according to its width. "Pitched roofs" are sold in the form of slabs, pressed and packed in polyethylene. They are used in the case of insulation of pitched and mansard roofs, as well as for surfaces inside and outside the building.

• "Isover Pitched Roof" used exclusively for roof insulation. It is moisture resistant, does not let in sounds, has high vapor permeability and is non-flammable. As a rule, it is recommended to use it in two layers, with the top one covering the joints of the bottom one - this way the material will retain heat even better. "Pitched Roof" is available in the form of slabs with a width of 61 centimeters and a thickness of 5 or 10 centimeters. "Pitched Roof" has a high hydrophobicity - it does not absorb moisture, even if immersed in water for a long time. This allows the material to be used in difficult conditions that are not suitable for other heaters.
• "Isover Ruf N" is a flat roof insulation. It has the maximum level of thermal protection and is compatible with any building materials.

• "Isover Master of Warm Roofs" also has a high rate of thermal protection. Due to its vapor permeability, it eliminates the accumulation of moisture in the wall. In addition, when insulated from the outside, the plate will retain its properties in any weather.
• "Isover OL-P" is a special solution for flat roofs. It has ventilated grooves to remove moisture and is created using the tongue-and-groove technology, which increases the tightness of the mineral wool layer.

Facade under plaster

To insulate the facade for the purpose of further coating with plaster, the following types of Isover are used: "Facade-master", "Plaster Facade", "Facade" and "Facade-Light". All of them are sold in the form of plates and are non-combustible material.

• "Facade-Master" p It is used for insulation of facades of residential buildings up to 16 meters high. The plaster must be applied in a thin layer.
• "Plaster Facade", which is an innovative material, costs much less than the previous one, but performs the same functions and is applied under the same conditions.
• "Facade" used for subsequent coating with decorative plaster.
• "Facade-Light" used for houses with a small number of floors and for subsequent finishing with a thin layer of plaster. For example, this option is chosen by the owners of country houses. Such material is strong, rigid, but light in weight.

For soundproofing buildings

In order to protect the house from various noises, both external and internal, "Isover Quiet House" and "Isover Sound Protection" are used. Besides, you can also use universal heaters - "Classic" and "Profi".

• "Quiet House" has a high ability to absorb noise, so it is often chosen for soundproofing walls and partitions between rooms. Plates are also used for horizontal surfaces - for logs, beams, spaces between the suspended ceiling and the original one. The material performs two functions, so the home becomes quiet and warm.
• "SoundProtection" has high elasticity, therefore it is often mounted inside the frame crate, which acts as a partition or is fixed on the wall (in the case of facade coatings). The material can be used in combination with other heaters and thus create a double layer that retains heat and does not let in sounds. Such a solution will be especially effective for creating frame partitions and attic floors.

Wall insulation inside

For thermal insulation and sound insulation of the walls of buildings inside and outside, Isover Profi, Isover Classic Slab, Isover Warm Walls, Isover Warm and Quiet Wall and Isover Standard are recommended. These heaters are sold both in mats in rolls and in the form of saws.

• "Standard" usually selected for thermal insulation structures consisting of many layers. In this case, siding, lining, brick, block house and other materials can be used as a finish. In addition, these plates are suitable for thermal insulation of frame structures, for mansard and pitched roofs. Due to the medium density, the material is not suitable for further plastering of walls. "Standard" has good elasticity, which means a snug fit to surfaces and structures. The plates are fixed using special clamping fixtures.

• "Warm Walls"- these are plates that are also made of glass fibers, but in addition are reinforced with a water-repellent treatment. This variety is also used for thermal and sound insulation of walls inside and outside, installation in a frame, insulation of roofs, loggias and balconies. Increased moisture resistance becomes an additional plus in the last two examples. The material is resilient and elastic, does not slip or break.
• "Warm and Quiet Wall" It is sold both in the form of plates and rolls. The material has a porous structure, which allows it to perform two functions. In addition, this variety is characterized by increased vapor permeability and, as it were, “breathes”. This allows you to create a comfortable environment in residential premises. The plates are elastic and do not even need to be additionally fixed - they themselves will qualitatively “spread” inside the frame.

• "Warm and Quiet Wall Plus" has similar characteristics to the "Heat and Quiet Wall", which will be discussed a little later, but has a lower thermal conductivity and better sound insulation. The slabs are used for walls inside the building, walls outside under siding or facade coverings and, with additional protection, for warming frame structures.

Floor insulation

In order to insulate the floors with high quality, you can choose two specialized materials - "Isover Floor" and "Isover Floating Floor", which have slightly different technical and operational characteristics, which, however, combine damping properties and mechanical characteristics. Both types are easy to mount, but using various technologies. In addition to insulation, these materials are also distinguished by high-quality bilateral sound insulation.

• "Flor" used for the construction of floating floors and structures along the logs. In the first case, the material covers the entire surface and creates a warm and quiet floor. Due to the adaptation to high loads, the insulation can also be placed under a concrete screed.

• "floating floor" always used to create a concrete screed that will not be connected to the walls and the base, in other words, for a "floating" floor. The plates are always laid out on a perfectly flat surface and connected using a technique called the “thorn groove”. Due to the fact that the fibers are arranged vertically, this type of insulation demonstrates outstanding strength characteristics.

Bath thermal insulation

For warming baths and saunas, Isover has special solutions - mats rolled up and called "Isover Sauna". This coating has a foil layer on the outside, which reflects heat and creates a vapor barrier.

"Sauna" consists of two layers. The first is mineral wool based on fiberglass, and the second is foil. It should be noted that mineral wool is a non-combustible material, and the foil coating has a flammability class G1. It can withstand temperatures up to 100 degrees due to the presence of glue, and at a higher temperature it can ignite and die out on its own. To avoid an accident, the foil layer is additionally covered with clapboard.

"Isover Sauna" on the one hand performs the functions of thermal insulation, and on the other hand, it is a barrier to steam so that the mineral layer does not suffer from a large amount of evaporation. The foil reflects heat away from the walls in the room and increases the level of heat retention.

Installation nuances

First of all, you need to choose right kind Isover, for this it will be enough just to look at the existing markings. Each product is assigned a class and number of stars, and these data are contained on the packaging. The more stars, the better the heat-shielding properties of the material.

To insulate a house without special requirements, two stars are enough; for increased thermal protection and ease of installation, three stars are selected. Four stars are assigned to the product of the latest generation with increased thermal protection. In addition, each package has a label with precise data regarding thickness, length, width, package volume and number of pieces.

Mineral wool insulation is mounted in the same way as any other heat-insulating material. When insulating the walls inside the room, the first thing to do is to make a crate of wooden or metal planks. Drywall will be attached to them later. The walls are pre-primed, and a heat-reflecting coating is fixed on those that border the street.

When installing the battens, it is necessary to observe a step corresponding to the width of Isover, slabs or mats. At the next stage, the insulation sheets are glued to the wall, if necessary, a water-repellent film is fixed and horizontal strips are stuffed.

Wall insulation outside the building begins with the fact that a wooden frame is attached to the wall.

• It is usually made from bars measuring 50 by 50 millimeters, which are attached vertically.
• Insulation can be mounted in one or two layers. It is placed in the structure so as to fit snugly against the wall and frame without gaps and cracks.
• Further, the bars are again attached on top, but already horizontally. The distance between the horizontal bars should be the same as between the vertical ones.
• With two-layer insulation, a second layer of thermal insulation is placed in a horizontal crate, moreover, overlapping the joints of the first.
• To protect against moisture, a hydro-windproof membrane is placed outside, the necessary ventilated gap is created, and after that you can proceed to the cladding.

Roof insulation begins with the fact that a hydro-windproof membrane, which is also produced by Isover, is stretched along the upper edge of the rafters.

• It is fastened with a construction stapler, and the joints are glued with reinforced mounting tape.
• Next, it is recommended to start installation roofing- a gap is formed on top of the membrane with the help of a pressure bar, and then a coating is installed on the counter-lattice of bars 50 by 50 millimeters.
• The next step is to install the heat insulator directly. With a standard distance between the rafters, the insulation will need to be cut into 2 halves and each installed in the frame. Most often, one piece manages to insulate the entire length of the roof slope. If the distance between the rafters is non-standard, then the dimensions of the thermal insulation boards are determined independently. We must not forget that their width should be at least 1-2 centimeters more. Thermal insulation should fill the entire space without gaps and cracks.
• Next, a vapor barrier membrane is installed along the lower plane of the rafters, which will protect against moisture inside the room. Joints are glued with vapor barrier tape or reinforced construction tape. As always, a gap is left and the installation of the inner lining begins, which is attached to the crate with nails or self-tapping screws.

Floor insulation along the lags is selected in two cases: attic floors and floors above basements with no heating.

• First, logs are installed and laid with roofing material to prevent rotting and destruction of the structure.
• Then the heat insulator material is installed inside. For cutting, a knife with a blade length of more than 15 centimeters is used. The roll is simply rolled between the lag so as to close the entire space, and no additional fixing actions are required. During installation, moisture of the material should be avoided.
• The next step is to install the overlapping vapor barrier membrane, the joints are glued as usual with reinforced mounting tape or vapor barrier tape. A base is installed on top of the vapor barrier, which is attached with screws to the logs.
• Everything ends finishing: tiles, linoleum, laminate or carpet.

When carrying out activities for the purpose of soundproofing partitions the first step is the marking and collection of guides and their further installation.

• At a free-standing partition, it is necessary to veneer one side with drywall, and you can begin to create sound insulation.
• Isover mounts between metal frame posts without fasteners, fitting snugly to the structure and filling the entire space without gaps or gaps.
• Then the partition is sewn up on the other side with drywall, and the seams are puttied using paper reinforcing tape.

Thermal insulation of baths and saunas starts with the creation wooden frame from bars measuring 50 by 50 millimeters.

• The bars are mounted horizontally.
• The insulation is cut with a knife into two halves and installed in the frame, while the foil layer should be turned inside the warm room. As usual, the material is installed without gaps and cracks.
• The joints are well glued with foil tape, as is the outer surface of the crate. All this will create a sealed vapor barrier circuit.
• A crate is placed over the horizontal bars to create an air gap. It will speed up the warm-up and increase the life of the skin.
• At the final stage, the inner lining is installed.

One of the main mistakes when using Isover is choosing the wrong material width.

If the insulation roll lies freely between, for example, beams, then the main goal will not be achieved. It will be quite costly to cut it into several rows, and leaving it in this state, despite the gaps and gaps, is completely pointless. Therefore, it is extremely important to calculate all the necessary dimensions for the work surface, taking into account the length, depth and width of the beams or battens.

In the event that the insulation is in direct contact with wires or pipelines, it is necessary to check the tightness of communications. In terms of electricity, the situation is not very dangerous, but in the second case it is better to isolate communications with a corrugated pipe.

In addition, all materials must be absolutely dry before the start of the insulation process. If the surface for which Isover is intended is wet, then you will either have to wait for it to dry, or dry the room with a hair dryer or gun.

But the worst mistake, of course, will be the lack of waterproofing and vapor barrier. If you miss these moments, then the material will be wasted, and the thermal insulation effect will not be achieved.

How to calculate: instruction

It is very important to be able to correctly calculate the required thickness of the insulation to create and maintain a comfortable temperature in the room. To determine it, it is necessary to reproduce the heat engineering algorithm, which exists in two versions: simplified - for private developers, and more complex - for other situations.

The most important quantity is the resistance to heat transfer. This parameter is referred to as R and is defined in m2×C/W. The higher this value, the higher the thermal insulation of the structure. Experts have already calculated the recommended average values ​​for various regions of the country that differ in climatic features. When building and insulating a house, it must be taken into account that the resistance to heat transfer must be at least normalized. All indicators are specified in SNiP.

When building and insulating a house, it must be taken into account that the resistance to heat transfer must be at least normalized. All indicators are specified in SNiP.

There is also a formula that shows the relationship between the thermal conductivity of the material, the thickness of its layer and the resulting thermal resistance. It looks like this: R = h / λ. R is the heat transfer resistance, where h is the layer thickness and λ is the thermal conductivity of the layer material. Thus, if you find out the thickness of the wall and the material from which it is made, you can calculate its thermal resistance.

If there are several layers, the resulting figures will have to be summed up. Then the obtained value is compared with the normalized values ​​for the region. It turns out the difference that the heat-insulating material will have to cover. Knowing the coefficient of thermal conductivity of the material chosen for insulation, it is possible to determine the required thickness.

It is worth remembering that in this algorithm it is not necessary to take into account layers that are separated from the structure by a ventilated opening, for example, determined by the type of facade or roof.

This happens because they do not affect the overall resistance to heat transfer. In this case, the value of this "excluded" layer is equal to zero.

It must be remembered that the material in the roll is cut into two equal parts, usually 50 millimeters thick. Thus, having identified the required thickness of the insulation squares, the product should be laid in 2-4 layers.

• To calculate the required number of standard packs for roof insulation, you will have to multiply the area of ​​\u200b\u200bthe roof to be insulated by the planned thickness of the thermal insulation and divide by the volume of one package - 0.661 cubic meters.
• To calculate the number of packs to be used for facade insulation for siding or lining, the area of ​​\u200b\u200bthe walls will have to be multiplied by the thickness of the thermal insulation and divided by the volume of the package, which can be equal to 0.661 or 0.714 cubic meters.
• To determine the number of Isover packs required for floor insulation, the floor area is multiplied by the thickness of the thermal insulation and divided by the volume of one package - 0.854 cubic meters.

Safety

When working with insulation, consisting of fiberglass, be sure to use goggles, gloves and bandages made of gauze or a respirator. Clothing should be with long sleeves and trousers, in addition, do not forget about socks. It is better, of course, to play it safe and wear protective overalls. Otherwise, installers expect unpleasant consequences - itching and burning all over the body. By the way, this requirement applies to all types of work with any mineral wool.

To protect the inhabitants of the house from glass dust, it is recommended to put a special film between the insulation and the top layer, for example, clapboard.

Even if the wooden panel is damaged, the insulation particles will not be able to penetrate the room. Material can be cut with simple knife, but it should be sharpened as sharply as possible, in extreme cases, you can use a fairly sharp chisel.

The insulation must always be stored in a dry, closed place, and the packaging must only be opened at the installation site. The room should be well ventilated, and after completion of work, all waste should be collected and discarded. Also, after completing the installation, you must take a shower or at least wash your hands.

To date, the construction markets are simply crammed with a variety of thermal insulation materials, which differ in price, types of forms, installation method and, of course, quality. Competing firms create new models of insulation, only to occupy the highest sales bar in the construction markets. There are materials that always remain in the lead. One of these materials is Izover. This is a heater, in which the technical characteristics reach simply colossal quality when insulating a room or building.

In terms of properties, Izover is very close to mineral wool, and also has its pros and cons. The material is produced in the form of pressed rolls with a rigid and soft structure, so it is excellent for insulating roofs, facades on buildings, ceilings and walls inside a room. The basis of the Izover material is fibers, which have a length of about 100-150 microns and a thickness of 5 microns. Such quality and dimensions increase the level of elasticity and resistance to the transfer of loads of external factors.

Technical characteristics of Izover

The Izover material is made of the highest quality fiberglass, and this is achieved through the use of TEL technology. Today Izover has no analogues on construction market. Izover has the following advantages:

Technical characteristics of insulation Izovol

The technical characteristics of the insulation have not only positive qualities associated with thermal insulation. There are also secondary advantages, such as service life, environmental friendliness and the weight of the insulation, which play a big role during installation.

Insulation release form

In order to increase the usability of Izover, many companies produce material in several forms. These can be rolls, slabs, and mats, which in their structure have different stiffness for insulating the outer or inner side of the wall surface in buildings, and the price also differs depending on the choice of the type of form.

Also distinguish single layer and double layer Izover. In the first case, the thickness reaches 5-10 centimeters. The two-layer material does not differ too much in thickness, since here the dimensions of one layer are about 5 centimeters. Plates can be about a meter in size, or rather, speaking, this is the standard that can most often be found on the construction market, but there are exceptions when ordering insulation on websites or from dealers.

One roll of Izover insulation is about 16–20 square meters, that is, quite large sizes. The width of the roll reaches 1.2 meters, while its length can vary from 7 to 14 meters. It goes without saying that the specifications will be slightly different depending on the choice of material size.

Varieties of Izover models

As mentioned above, the isover material has many models and this is not surprising, because its application has a fairly wide scope. Heater can be used indoors, which means that the model will already be, it does not have such a rigid structure due to minimizing the impact of external factors, but when insulating the external surfaces of buildings, most often Izover already has a different structure. In fact, there is a whole list of models of insulation.

Model Isover KL34
