Drywall type a. Drywall - sheet dimensions

Drywall is a versatile building material used for finishing ceilings, walls, ventilation shafts and basements, as well as for the construction of various structures. Drywall sheet (GKL) is a kind of sandwich of a couple of layers of building cardboard, with a solid gypsum core in the middle. By adding various modifying additives to the composition of gypsum, as well as impregnating the cardboard with special mixtures, the manufacturer achieves the production of gypsum building materials with different functional characteristics.

Types of drywall according to the general classification

• GKL - ordinary drywall, used for finishing domestic and office premises, in which the temperature and humidity parameters do not exceed permissible standards. So, normal humidity is considered to be up to 70%. This species has a gray color with blue markings.
• GKLO - fire-resistant drywall, special kind, which has increased resistance to open flame, which is achieved by adding reinforcing components to the core material. Used for decoration industrial premises, ventilation shafts, attic space, electrical panels. GKLO is gray with red markings.
• GKLV - moisture resistant drywall, which has antifungal components and silicone granules in the composition of gypsum, which allow the sheet to remain neutral to high humidity. For GKLV use impregnated cardboard. To achieve the best moisture resistance, it is recommended to protect the front side of the sheet with various coatings, for example: waterproof paints and primers, PVC, ceramic tiles, waterproofing. This type is used for finishing rooms with high humidity parameters: bathrooms, kitchens, garages. GKLV color - green with blue markings.
• GKLVO - moisture-resistant and fire-resistant drywall, combines the properties of GKLV and GKLO materials. It is used when finishing industrial premises with high humidity and having increased requirements for compliance with fire safety standards. GKLVO color - green with red markings.

In addition to dividing into varieties, different types drywall have different types edges.

Varieties by type of edge

• PC - straight edge. Designed for "dry" installation, does not require laying joints. It is used when covering the surface in several layers, for internal layers.
• UK - thinned edge. It is used when pasting with reinforcing tape, followed by puttying.
• ZK - rounded edge. It is used when using putty, but without reinforcing tape.
• PLC - edge, semicircular on the front side. It is used without reinforcing tape, with further putty.
• PLUK - an edge, semicircular and thinned on the front side. Requires the use of reinforcing tape and putty.

More often than others, types of drywall with beveled edges UK and PLUK are used, since they allow you to close the seams without the formation of protrusions.

Standard dimensions for drywall sheets

Sheet length - 2500 mm or 3000 mm. Some manufacturers have sheets of smaller lengths, but they are more expensive, although they are easier to work with.

Width - 1200 mm.

Thickness - 6 mm, 9 mm, 12.5 mm. Small thicknesses are used for sheathing curved surfaces, creating arches. Some experts suggest using a 9 mm sheet for finishing ceilings. There is, however, an opinion that the ceiling sheathing, as well as the wall sheathing, requires a sheet thickness of 12.5 mm.

Andrew. said):

Raisa managed to level the walls with the help of drywall. And I saved money and hired cheap specialists. They didn't measure correctly. Now my room has the shape of a parallelogram. Especially noticeable on the ceiling. Advice, do not save on employees!

Max M said:

After reading the article, I learned that there is drywall with a thickness of 6 mm. Although in most stores there are mainly 2 sizes to choose from - 9 mm and 12.5 mm. Of course to make arches and different designs with thin plaster is much more convenient. And we had to take an ordinary thick drywall, make a notch on the back or cut it into strips, moisten it with water and wait until the sheet bends.

Raisa said:

we are doing repairs in a recently purchased house, everything is crooked in it and the walls and ceilings. we took drywall of various thicknesses and leveled everything. after pasting the walls with wallpaper and the ceiling with tiles, everything looks just perfect.

Julian said:

there was a case, I had to “build” new house inside old box. Naturally, all the partitions and the ceiling were made of gypsum. Here are some useful findings:
- so that cracks do not appear at the joints, they must be glued with a mesh before puttying. Self-adhesive tape for sale. It reinforces the plaster layer and it does not crack.
- when cutting sheets, it is not necessary to mark the details with a pencil. Small cuts with a cutter are enough, they are very clearly visible, in case of an error they are not critical, and one step in the work becomes less - all the same, it turns out faster.
- the backlog of success is a high-quality installation of a frame from profiles. If it is made with high quality and evenly, then the installation of drywall is a pleasure.

Irina said:

She communicated the ceiling and boxes in the kitchen with sheets with a thickness of 9 mm. We decided that 6 is a bit thin, 12.5 mm is heavy and requires additional fasteners. The ceiling turned out great, it has been standing for several years. The main problem is vibrations and oscillations from above (I don’t have powerful reinforced concrete floors in my kitchen). Therefore, over time, cracks form at the joints of the GKL, but this is not critical. And DEFINITELY you should not save on moisture-resistant sheets in the kitchen. Additional investment in moisture-resistant drywall justifies itself completely!

Many parameters are evaluated by experienced specialists in order to choose the right one. Sheet dimensions, thickness and price are no less important than the scope and conditions of future operation. For a correct analysis, all significant factors should be taken into account in the aggregate.

Right choice drywall will help to successfully implement complex projects

The building material parameters can be found in the relevant official standards. They contain the most accurate information. Plasterboard sheets, or "GKL", "gypsum board" are described in GOST No. 6266-97. This is an interstate document that was developed in Russia and has been in force since April 1, 1999. It has been approved by the executive authorities in Belarus, Kazakhstan, Moldova and Armenia.

Useful information! On the territory of the Russian Federation, the sale of building materials manufactured according to other standards is not prohibited. The only significant limitation is harmlessness. If the accompanying documentation contains a link to the mentioned GOST, then you can use the information from this article for verification and comparison.

From what and how these products are made

The composition is clear from the name. Cardboard is fixed on the outer sides of the sheet. For its manufacture, wood pulp is used, which explains the impeccable environmental characteristics. The pressure under the press creates a density of 0.17 - 0.22 kg per sq. m. This range is normalized by another standard (No. 8740-85). Compliance with these rules provides sufficient strength and rigidity of the structure, resistance to mechanical stress. To improve resistance to high temperatures, cardboard is impregnated with flame retardant additives.

Gypsum is a salt of natural origin. It is formed naturally from sea ​​water. Deposits of these substances are developed industrially. Raw materials are fired at a relatively low temperature (180-190°C), crushed. To create products of the desired shape, a solution with water is created. Fiberglass is added to it to increase fire resistance. The same component helps to maintain the integrity of the product during deformation.

Physical and mechanical characteristics

These sheets are used in building structures, so one of the most important criteria is load resistance. The following standards are established for maximum non-destructive impacts with a tolerance of less than 10% in both directions:

GKL thickness in mm
6,5	12,5	5,4
12,5	32,2	10,5
18	44	13
24	49	13,6

For verification, tests are carried out with reference lines set at a distance of 35 cm. Water absorption is limited to 10%. When exposed to an open flame, the integrity of the structure must be maintained for at least 20 minutes. The latter requirements refer to protected modifications.

purpose

From the above data, it is clear that the use of special additives allows you to change the initial parameters of drywall. Therefore, sheet dimensions, thickness and price should be taken into account together with the intended purpose of the product:

• For finishing walls and ceilings in residential and office space apply basic types products, "GKL".
• The corresponding letter is added to the abbreviation of moisture-resistant sheets - "GKLV".

• Resistant to open fire modifications are marked like this - "GKLO".
• For maximum protection against potential adverse effects, GKLVO is installed. These sheets do not absorb moisture and retain their integrity for a long time at high temperatures.

Dimensions, thickness, weight of drywall sheet

This material lends itself well to processing. Therefore, it will not be difficult to cut blanks with the desired geometric parameters. AT next list the norms from the standard are given:

• The standard size of a drywall sheet (length) is created from 200 to 400 cm in increments of 5 cm.
• There are only two widths, 60 and 120 cm.
• Builders use various sizes plasterboard wall. But the thickness is often chosen 6.5 or 12.5 mm. In addition to these, GOST gives the following allowable values ​​(in mm): 8; 9.5; 14;16;18; twenty; 24.
• The ends of the sheets create: straight, rounded, smoothly or evenly thinned on one side.

To calculate, multiply the thickness of the product by the coefficient from the table.

Two groups of products "A" and "B" are installed. They differ in the accuracy tolerances that are applied during the production process. The following table shows data on permitted deviations:

It is not forbidden to manufacture products on an individual order. In this case, preliminary preparation is necessary. terms of reference and harmonize it with the capabilities of the manufacturing enterprise.

Overview of market offerings

Below in one table are collected prices for different types of GKL. These data will not help you find out exactly how much moisture-resistant drywall currently costs. The price and size of the sheet must be specified immediately before purchasing the goods, based on a specific project. But the information is useful for a comparative analysis of modifications, the name of the manufacturer:

Image	Trademark	Sheet view	Dimensions in mm length x width x thickness	Cost, rub.
	Volma	GKL	2500 x 1200 x 12.5	186
		GKLV	2500 x 1200 x 12.5	260

How to purchase suitable drywall: sheet dimensions, thickness and price, other important criteria

The above grouping allows you to determine by name possible disadvantages and other features. So, for example, according to the standard, in GKL "A" there should be no chips and other damage to the edges, corner parts. Such products can be installed in visible places. In sheets "B" such defects are allowed in the amount of not more than 2 per item. They can be removed with putty before finishing along with other gaps and irregularities.

Sealing gaps and joints

This example illustrates the importance of considering future work. When creating a false ceiling, the sheets are fixed with self-tapping screws on a special frame. It will take additional alignment surface, so it would be wiser to purchase relatively cheap products of group "B".

When calculating structural loads, you can use the manufacturer's reference data, or a simple formula. To find out the weight of a sheet of drywall 12.5 mm with an area of ​​1 sq.m. it is necessary to multiply the thickness by a constant factor of 1.35 (12.5 * 1.35 \u003d 16.875).

When drywall is selected, sheet dimensions, thickness and price are checked along with thermal conductivity. In standard products, the value of this parameter is in the range from 0.2 to 0.36 W per m * K. Frame voids can be filled mineral wool, Styrofoam. This design will significantly increase the insulating characteristics of the property. Such solutions are used to protect against noise and maintain a comfortable temperature in the premises.

Modern repairs require materials that would give maximum opportunities, this is exactly what drywall is now. With it, you can build walls, partitions, level surfaces, do everything that will decorate, change and transform a living space.

To work properly with such material, it is important to know its features, and to calculate the quantity, you need to understand what the sizes of drywall sheets are.

Material types

Drywall as a composite material has found application in the repair of a wide variety of premises, with its help new structures are created, existing ones are improved and the structure of the room is changed due to extensions, piers and partitions. To properly use this material, you must be able to select it for a specific type of work.

There are several types of drywall:

• Ordinary, which is marked with the abbreviation GKL. Inside the product is a gypsum dough, which is closed on both sides with thick cardboard. It is most convenient to use such sheets for interior decoration premises. It is important to use them where the humidity will not be high, otherwise the material will swell and lose external qualities, which will affect the reliability of the entire structure. Sheets of this type are convenient and fast to work with, they are light, flexible and economical.

The most common area of ​​​​use is working with the ceiling, less often with the floor, but most often it is taken for walls, to level them or create new ones.

• fire retardant, which is called GKLO, is most favorable for use in non-residential premises, creating partitions. With it, you can secure the space from the threat of fire, which allows you to use it for fireplaces and stoves.
• moisture resistant, has the designation GKLV, is used in rooms where the level of humidity is significantly increased, this is a kitchen and a bathroom. To provide such properties, substances are added to ordinary drywall that help not to absorb moisture, thereby maintaining all the characteristics of the sheet. This option well resists the formation of mold and fungus on its surface. If the premises are too high level humidity, it is recommended to use a different finishing option for them, because drywall will still begin to deteriorate from excessive moisture.
• fire and moisture resistant, with the GKLVO marking, is distinguished by the presence of resistance to both fire and water.

If you need to build special building construction, then we can distinguish additional types of material that have different level thickness is:

• arched variety with a thickness of 6.5 mm;
• ceiling, which has a thickness of 9.5 mm;
• wall the thickest variation, where the thickness is 12.5 mm.

The thinnest option is needed to create interesting curved structures both under the ceiling and as a wall. The ceiling type is well suited for leveling the surface of the ceiling or creating interesting design illuminated from above the room. The wall type is appropriate both for leveling walls and for interior partitions, which, due to its thickness, helps to achieve good sound insulation.

Standards

The size of drywall can be different, which is convenient in case of a large repair or the elimination of small surface irregularities. To be able to buy required amount material, there are standard dimensions of this material, where the width of the sheet is 1.2 m, and the length varies from two to three and a half meters. In addition to these characteristics, it is worth considering the thickness of the plasterboard, which affects the total weight. Its fluctuations can be within 65 mm and reach up to 125 mm.

Differences in thickness are extremely important for ceiling structures, the lighter they are, the easier they are mounted and do not create a risk of breakage. In addition, the lighter weight allows fewer supports to be installed, reducing repair costs. Each sheet has a different cost: the thinner, the cheaper, which makes it possible to save money, if the design allows.

Due to the fact that various companies began to produce this product, and each strives to gain its authority, there are cases when the dimensions of the GKLV sheets do not match the standard ones.

Length

Typical indicators of the length of a drywall sheet are:

• the minimum indicator is 2 meters;
• the maximum option is 3.6 meters.

If we consider Knauf products, then here we can note the maximum figure of 4 meters. The difference between the size range of each option is 50 cm. The greater the height of the sheet, the stronger and thicker it should be, and, accordingly, heavier. Most often, maximum dimensions are used in large spacious rooms for a large amount of work. Thus, it turns out to increase the pace of repairs, reduce waste and reduce the cost of material costs.

For experienced builders it is not difficult to work with any dimensions of the product, and for beginners it is better to start with small sizes that are easier to measure, cut and make the necessary product. Long sheets are best suited for walls, ceilings and floors, and short sheets for finishing windows and low partitions.

Width

The width of the drywall slab is a standard unit, and is 1.2 meters. Whatever the length of the sheet, this parameter remains unchanged, and only the thickness increases to increase strength and prevent brittleness. If there is an urgent need to find a small sheet of plasterboard, then Knauf will help here, because in their range there are products from 60 cm wide, which in some cases will be the best option.

Non-standard width will fit when it comes to repairing window slopes after replacement wooden products on plastic. In this case, it becomes necessary to close the hole left by the second frame and make the wall surface even. But also pieces small in width are suitable for creating a variety of drywall constructions that will have small dimensions.

Working with such plates is much more convenient than with full-sized ones, which means that anyone, even a beginner, can handle it.

Thickness

Depending on the size of the drywall sheet in length and width, the thickness of the product also changes. This is due to the fact that the pressure on the material increases, and without proper reinforcement, the cardboard will not withstand, and the gypsum mass will destroy itself. For small dimensions of GKL, the thickness will be 6.5 mm, for larger ones - 9.5 mm, and the largest figure is 12.5 mm. If a particularly complex object is being erected, which should be as strong as possible, then it is worth using a 24 mm thick plate.

The choice of thickness depends on what exactly will be made of the material. If this is an interior partition without any functions, you can use thin and medium options, if it has a shelf for books, then the requirements increase, and it is better to take a medium or thick sheet of drywall.

For those cases when a constant and considerable weight will affect the surface of the GKL, or there will be a valuable object like a TV on it, it is best to use the thickest type of plate.

The weight

Depending on the indicators of the length of the sheet, its width, including the thickness, the weight of the sheet will also change.

If the sheet is:

• 1200 by 2000 with a thickness of 6.5 mm, its weight will be 12 kg;
• 1200 by 2500 mm with the same thickness, the weight will increase to 15 kg;
• 1200 by 3000 with a thickness of 6.5 mm, the sheet weighs 18 kg.

The weight changes in proportion to the thickness of the GKL plate, as follows:

• 1200 by 2000 with a thickness of 9.5 mm will weigh 18 kg;
• 1200 by 2500 by 9.5 mm will weigh 22 kg;
• 1200 by 3000 mm with the same thickness will weigh 27 kg.

If the first two options can be used on the surface of the wall and ceiling, then the third one is not suitable for suspended structures due to the significant weight of the sheet, since:

• 1200 by 2000 with a thickness of 12.5 mm, weight is 23 kg;
• 1200 by 2500 by 12.5 mm will weigh up to 27 kg;
• 1200 by 3000 mm with the same thickness will weigh 35 kg.

Knauf drywall has large quantity product options both in length and thickness, in addition to the standard 6.5, 9.5 and 12.5 mm, there is also 15 mm.

The weight of the GKL sheet of this company will have the following indicators:

• 1200 by 2500 by 15 mm weighs 15 kg;
• GKLV with the same indicators will weigh the same;
• The weight of GKLO of the same dimensions will be from 13 to 16 kg;
• the same indicators will be on the GKLVO sheet.

Only after understanding all the numbers and values, you can choose suitable option product and start working with it, otherwise it will be difficult to hope for an easy repair process and a good result.

What do dimensions depend on?

A standard sheet of drywall has only one stable indicator, and all the others may vary depending on the scope of its use. For the right choice of material, you need to understand which type is suitable for which work.

There are such types of GCR as:

• arched sheets;
• reinforced;

• acoustic, with perforation;
• vinyl coated sheets.

Acoustic

laminated

Acoustic drywall sheets are best used for large rooms such as auditoriums or halls that need to have an acoustic effect. If we consider vinyl sheets, then their undoubted advantage will be the readiness of the material for use, no treatment needs to be applied to the surface. The scope of its use is narrower due to the inability of the material to breathe.

Concerning arched version, then it is the most versatile, having a small thickness, so you can use it to create any composition.

If the matter concerns the wall type of the product, then it is necessary to exclude thin sheets, which in this case will be inappropriate. Only the use of 12 and 15 mm plasterboards will allow you to build a reliable and strong wall.

If it is necessary to cover the wall, then the ideal option is to serve a sheet of 9 mm, with which it will be convenient to carry out all the necessary manipulations.

When choosing options for future walls or walls in the bathroom: you can also use drywall for this room, with the help of a moisture-resistant option, you can avoid getting wet and delamination of the material.

Knowing the types of products and their sizes allows you to choose the right material for repairs. If you need to finish the whole room, then standard sheets will be the best choice. In the case when the walls in the room have a non-uniform height, it is more convenient to buy non-standard sheets that are half the size. For places that will have to withstand heavy loads, the thickest type of product should be used.

When planning the manufacture of an interior partition, it is best to use the longest plasterboards, which can reach 4.8 m, which will significantly speed up the repair process and save you from buying unnecessary materials.

If such partitions are radial, then it is advisable to use two sheets at once together to strengthen the structure.

For aesthetes, and those who seek to make something unusual and beautiful in the house, they will need a designer type of plasterboard, which is also called arched due to the fact that its thickness is only 5, 6, sometimes 6.5 mm, it can be easily bent. In order for such a product not to burst from loads, it contains two whole reinforcing layers.

If speak about non-standard materials, then it is worth remembering the soundproof type from Knauf, which has increased hardness and, in addition to standard thicknesses of 12.5 mm, there are also 10 and 15 mm options.

The choice of product thickness is dictated by the location. Thin sheets are attached to the ceiling so as not to overload the structure, medium and thick sheets can be laid both on walls and on the floor. For creating original compositions a thin material is needed, for wet rooms it is moisture resistant, and in the case of contact with a strong heat source, fire-resistant drywall is required.

Only by choosing the right varieties and sizes for the product, you can optimally calculate the amount of materials for work and make repairs with minimal loss of time and cost.

Overview of offers from different brands

When planning significant repairs that will require drywall, you need to know how to choose it correctly, and most importantly, which brand of product to pay attention to. Due to the fact that the popularity of this finishing material is growing, there are more and more new brands in which you can easily get confused and make the wrong choice.

If we talk about the most popular company, then this is the German manufacturer Knauf, which focused its products on the purpose, which was reflected in the characteristics:

• the ceiling version has a thickness of 9.5 mm;
• wall - 12.5 mm;
• for a variety of bizarre designs - 6.5 mm.

The length standard is 2.5 meters, but there are other options, more and less than these indicators. The smallest sheet length is one and a half meters, and the largest is 4 meters. The width here also deviates from generally accepted standards, the minimum is 60 cm, and the maximum is one and a half meters. The thinnest sheet is 6.5 mm, and the thickest reaches 2.4 cm. All these indicators also affect the weight of the product, which can range from 13 to 35 kg.

Like any professional firm, Knauf produces not only standard version sheet, but also one that is suitable for wet rooms, for the manufacture of structures in contact with fire, and a mixed type.

The quality of products has been tested over the years, this brand makes durable products that are lightweight, good flexibility, they are easy to cut and convenient to grind.

If we talk about the domestic representation, then the Volma brand will be the clear leader, which differs in mass positive qualities, this is:

• ease of installation process;
• reliability of materials;
• excellent strength indicators;
• wear resistance;
• the presence of an edge that prevents the sheet from crumbling;
• reinforced design for bending GKL;
• environmental friendliness;
• optimum price level.

When compared with world brands, one can note small nuances that go to the minus of this brand. For example, there are no marking lines on the sheets, the drywall itself is heavy, and the surface is slightly waviness, which requires additional processing.

Another brand is LaFarge, which is widely represented in the world, and is rapidly increasing the number of points of sale of its products. Due to good turnover price policy The company allows not to overestimate the cost, making products available to almost everyone. feature this production is the manufacture of sheets with a rounded chamfer and edges, which are pasted over with a cardboard film. It was this innovation that made it possible to make a perfectly flat surface.

If we note the shortcomings, then we can only highlight a small size range, namely, only 2 types with a length of 2.5 and 3 meters. The weight of the sheets is small and usually does not exceed 9 kg. Despite the lightness, the material is very durable and allows you to isolate sound and heat well.. Sheets are a special series in production, with which you can create arches and various curved structures.

Another interesting company is Gyproc. represented by the Scandinavians. On the this moment is a leading brand that has earned its popularity with environmentally friendly materials. Thanks to a special approach and choice of materials, the sheets are even lighter, which has also become an advantage of Gyproc brand products.

Drywall of this company can be used indoors, for which sheet options are presented from two and a half to three and a half meters in length, but with a standard width.

There are other brands that have their own differences. Magma's products presented on the market with a wide variety of products, among which there is drywall. Its quality is not bad, but it does not differ in any significant indicators. When choosing a brand, it is important to clearly understand what characteristics the product should have in order to find the optimal solution.

If it is important to cover the maximum area with the minimum number of sheets, then it is better to choose Knauf, which will also help when small panels are needed.

There are times when products of little-known companies turned out to be of high quality and inexpensive, but often eminent analogues significantly exceed cheap ones in quality, materials, environmental friendliness and other important indicators, so it is important to make the right choice.

How to make correct calculations?

In order to correctly calculate the required amount of drywall for repairs, the first step is to make all measurements of the repair area, be it walls, floor or ceiling. The choice of sheets is carried out according to the principle of selecting a longer length so that you can cut off an unnecessary part, rather than buying obviously smaller dimensions, so that later you can add the missing parts. Choosing the right size allows you to minimize the number of seams, which will then affect the duration of the finishing work, in addition, such a design will be stronger, and therefore reliable and durable.

Professionals can easily calculate how many sheets and what dimensions are needed for a particular job, but for a beginner, this not an easy task. In the absence of experience, it is important to draw a map of the surface on which work with GKL will be carried out, and by cells clearly determine the height and width of the sheet, and, accordingly, their number.

For those who do not like to deal with drawings, you can rely on the dimensions of the room, but buy material with a margin of 10 or even 20%.

The same principle works for working with the ceiling. After careful measurements, it is necessary to purchase sheets of a suitable size, they will be better bigger size than less, so that you can cut off the excess than add it. The fewer seams there are on the ceiling, the more beautiful the surface will be and easier job with her. In order to achieve this effect, it is important to correctly place the sheets, having data on the width and length of the repair site. If it is difficult to do this mentally, you can also use a drawing on which to try several placements, choosing the most suitable one.

When choosing drywall for a particular room, it is important to understand its specifics in order to choose the appropriate variety and size for the optimal number of sheets that will be required for repairs.

By correctly calculating all the indicators, you can get a good and high-quality result.

In the event that at home or in any other room there is a repair that requires drywall, then it is important to choose it correctly, for which you should pay attention to important factors:

• Choice of place of purchase: market or hardware store. Products on the market may be stored in inappropriate conditions, which negatively affects performance characteristics products. The store often has optimal conditions for storage and certificates confirming the authenticity of products. Building supermarkets allow you to choose a product from a relatively large variety of companies that differ in characteristics and price.
• Inspection of the place of purchase and warehouse. If it's important to get quality repair, then it is worth asking how exactly the materials that will be delivered for work are stored;

• Unloading and loading works. If possible, it is worth being near the loaders at the time of loading and unloading the sheets in order to see any violations in the process. This will help avoid any damage to the drywall.
• Upon receipt of the goods, it is necessary to inspect it well sheets must be even, clean and uniform. The presence of chips, dents and scratches indicates poor quality, problems with storage or transportation.

It is best to return damaged sheets back, otherwise their service life may be significantly reduced.

When buying drywall for the first time, and you need a lot of sheets to work, you need to check the product of a particular company from a particular supplier. Only one sheet is bought and cut into strips. It is required to carefully inspect the contents of each strip, evaluate whether the composition is homogeneous or not, whether there are external differences.

If everything is in order, and there are no questions, you can safely order the required amount of GKL from this batch. But in case of doubt, it is better not to risk it, and look for another option.

When planning the interior decoration, it is worth especially carefully checking the composition of drywall, because small firms that offer an affordable product can add harmful substances during operation, they will emit toxic fumes or odors that adversely affect human health. This is especially important for the repair of a children's room, where everything should be as natural and of high quality as possible.

Do not forget about the specifics of the premises: for shower, toilet and kitchen the best option- this is a moisture resistant GKL, and in ordinary rooms suitable standard version designed for dry residential areas. Thin and light structures are used on the ceiling, and as thick and durable as interior partitions.

The right choice of drywall sheets will be the basis for a successful and beautiful repair in any room.

Tips for using and installing drywall are waiting for you in the next video.

For a certain type of work, it is necessary to choose the appropriate type of drywall. Types of this material are distinguished by properties and purpose.

Types of drywall by properties:

1. ordinary drywall or abbreviated GKL
2. moisture resistant - GKLV
3. fire resistant - GKLO
4. moisture-fire resistant - GKLVO

GKL

Ordinary drywall sheet consists of thick cardboard, which serves as the surface of the material, and gypsum dough. It is used for finishing rooms with normal humidity conditions. It should be noted such advantages of the material as efficiency, relatively low weight, ease of use.

GKLV

It is easy to guess that a moisture-resistant sheet is used in wet areas, such as a bathroom or kitchen. GKLV contains additives that reduce moisture absorption , do not delaminate and do not lose their shape. This type of drywall is resistant to mold and mildew. When choosing a finishing material, for example, country house, stop on moisture-resistant drywall, as the humidity in a country house is higher than in a city apartment.

Sometimes when finishing a bathroom it is better not to use drywall at all. If the family has four or more people, each of whom takes a bath every day, it is better to refuse to use even moisture-resistant GKL. For finishing rooms, in which the humidity goes off scale, it is necessary to use more moisture-resistant materials.

GKLO

Fire-resistant drywall - this material is great for lining utility and non-residential summer premises, building partitions. GKLO provide the necessary fire safety and can be used near fireplaces and stoves.

GKLVO

This type of drywall has both the properties of fire-resistant and moisture-resistant sheets.

In addition to the listed types, they also produce a special repair GKL, it is used to correct minor damage in an already finished drywall construction.

Types of drywall for the intended purpose:

1. wall - thickness 12.5 mm
2. ceiling - thickness 9.5 mm
3. arched - thickness 6.5 mm

Wall drywall is used for wall decoration and sheathed ceiling, arched is best suited for creating stylish and all kinds of curved openings.

For wall and ceiling cladding, it is desirable to use solid sheets. Their number must be calculated in advance. The standard size of a drywall sheet is 2500 by 1200 mm. The area of ​​the sheet is exactly three square meters. There are also custom sizes drywall: length from 1500 to 4000 mm, width from 600 to 1500 mm, thickness from 6.5 to 24 mm, so be sure to check the size with the seller before buying. Whole cl can only be used for cladding large areas, and when repairing small apartment it will have to be cut to size.

Characteristics of GKL KNAUF

Below are tables of the main technical parameters drywall Knauf, which you need to know when buying it.

Drywall is one of the most popular building materials. The main advantage of the material is that its use allows you to expand the range of design solutions and create designs of the most different forms, finish walls and ceilings in any premises. This article discusses the parameters that allow you to choose the right drywall: price per sheet, dimensions, thickness, purpose, and others.

The main material that is part of the drywall sandwich is gypsum. It is a natural salt, which is formed naturally from sea water.

In order to obtain a gypsum plasterboard (GCR), the extracted raw material must undergo pre-treatment, which includes two processes:

• burning. The temperature at which such a process takes place is approximately 180–190°C;
• grinding.

For the manufacture of GKL of the desired shape, a solution is mixed with water, sometimes fiberglass is added. It is a component that significantly increases the deformation resistance of GKL, and also positively affects the refractory qualities. On both sides of the gypsum sheet, cardboard is fixed, which is environmentally friendly. Such cardboard is made from cellulose and impregnated at the production stage with special flame retardant additives.

The main types of drywall sheets

Depending on destination and technical features All GCRs are divided into the following types:

• standard;
• moisture resistant;
• fire resistant;
• waterproof and fireproof;
• acoustic.

Standard and moisture resistant plasterboard sheet 12 mm. Price per sheet and specifications

Standard GKL is used when it is necessary to perform interior finishing work. With the help of standard GKL, walls are leveled, and partitions, multi-level ceilings, etc. are equipped. To calculate materials for finishing work, you need to know the length and height drywall sheets. Sheet dimensions are usually 2500x1200 mm. Cardboard for standard sheets is gray and is indicated by blue markings. Standard GKL are used in rooms with normal humidity.

Moisture-resistant plasterboard sheets are used in rooms whose humidity level exceeds the permissible values. But its use is advisable only if the room has an exhaust ventilation system. In turn, the front surface of the sheet must be provided with a waterproofing material (paint, primer, PVC coating).

The dimensions of the moisture-resistant gypsum plasterboard are the same as those of standard gypsum boards. Such sheets are used for the construction of slopes. GKLV in combination with waterproofing materials are used for sheathing work surfaces in rooms with a high level of humidity. These include the bathroom.

Useful information! Moisture-resistant drywall is characterized by increased strength; it can be used for decoration of public premises.

The material includes various hydrophobic additives, due to which the sheet is able to absorb a minimum amount of moisture (no more than 10%). In this case, the sheet has green color and is marked in blue. The price and size of a moisture-resistant drywall sheet may vary. However, products of standard sizes (2500x1200x12 mm) range from 295 to 395 r per sheet.

Fire-resistant, water-resistant and acoustic drywall

Refractory building products are used when it is necessary to finish the surface, which is located in close proximity to the source of fire (for example, the inner surface). This is exactly the option, which is mixed with fiberglass, which makes it resistant to fire.

Refractory sheets are used in rooms where the humidity level may be low or normal. Cardboard in this case can be either pink or red. Gypsum plasterboard refractory sheets are marked red.

Waterproof and refractory gypsum board (GKLVO) has a high fire resistance coefficient, and also has a reduced water absorption. The combination of properties allows the use of such plasterboard sheets in baths and steam rooms. However, it can also be used for ordinary finishing works indoors. Cardboard GKLVO sheet is different in green and red markings.

Acoustic GKL differ from other varieties in that it has a high sound insulation coefficient. This property allows this material to be used for wall and ceiling decoration in concert halls, dance studios, as well as rooms where sound recording is made. The main difference between acoustic drywall and standard plasterboard is that its surface has holes, with a cross section of about 1 cm. The reverse side of the acoustic plasterboard is equipped with a coating that does an excellent job of absorbing sound waves.

Dimensions of drywall sheets: length, height and thickness

The standard length of the GKL is 2.5 m, and the width is 1.2 m. The following dimensions can also be attributed to the standard length: 3 and 3.5 m. In addition to standard sizes, you can find plasterboard sheets in markets and hardware stores, the length of which maybe 4 m. Sometimes there are sheets with a length of 1.2 m (small). The dimensions and prices of drywall are interconnected. For example, sheets with a thickness of 9.5 mm are cheaper than twelve-millimeter products.

The standard width of a drywall sheet is 1200 mm (1.2 m), however, there are products on sale in which this figure can be 2 times lower (625 mm). Such sheets will cost less.

As for the thickness of the GCR, the standard indicators include the following:

• 12.5mm;
• 9.5 mm.

Deviation from the thickness standard is also a common practice. If necessary, you can purchase GKL with a thickness of 6.6 mm. In this case, their mass will be much lower, as well as the cost of drywall per sheet. There are also sheets with a different thickness - from 8 to 24 mm, which can significantly expand their operational area.

Differences between wall and ceiling plasterboard

The dimensions of wall drywall in the form of sheets may be different, however, they are all considered standard. The length of the wall plasterboard varies from 2000 to 4000 mm. The minimum width is 625mm and the maximum width is 1200mm. The standard thickness of drywall, which is used for wall cladding, is 12.5 mm.

Note! For wall decoration, sheets are most often used, the dimensions of which are 2500x1200x12.5 mm.

If it is necessary to sheathe walls in an apartment or house with high ceilings, then it is recommended to use sheets with the greatest length (4 m). Thus, we can conclude that the dimensions of the GKL are selected depending on the specific situation.

Drywall used for ceiling mounting should be lighter in itself to make the installation process as easy as possible. For sheathing ceilings, GKL with a thickness of 8 or 9.5 mm is used. The minimum thickness allows for a reduction in the weight of the suspended ceiling, which in turn allows you to reduce financial costs when purchasing profiles for fixing drywall.

The price of a plasterboard ceiling is much lower than in the case of installation wall material. If necessary, you can use the services of professionals who, on average, take about 250 rubles. for the installation of 1 square meter of plasterboard ceiling. The price per m2 of drywall installation on the wall and ceiling also depends on the complexity of the work.

Overview of the cost of installing GKL:

The price per m2 of installation of plasterboard partitions is calculated depending on the number of layers of drywall (1 or 2), as in other cases. Thus, we can conclude that the prices per sq. m. of drywall installation differ depending on the installation site, the complexity of the work (including the creation of curly elements), the number of layers of gypsum material, etc.

In order to answer a common question: how much drywall sheets weigh, you need to familiarize yourself with the data presented below. The table below shows the dependence of the weight of the GKL on their dimensions.

GKL weight dependence on dimensions:

GKL dimensions, mm	GKL thickness, mm	Weight, kg	Average cost, rub.
2000x1200	9,5	18	230
	12,5	24	150
2500x1200	9,5	22,5	195
	12,5	29	210
3000x1200	9,5	35	435
	12,5	27	400

Note! The weight of the drywall sheet 12.5 mm is indicated for a reason. Such sheets are in the greatest demand among buyers.

How much does drywall cost: an overview of the types and prices of various modifications

For each person who is going to use GKL for the interior decoration of his house or apartment, first of all, you need to study how much a drywall sheet costs. Prices that can be found on the Internet vary depending on the brands and sizes of the GKL. The price can be shown as square meter material, and for a full sheet.

To date, there are quite different, in terms of cost, drywall sheets. If you wish, you can purchase very cheap products, the price of which will be no more than 150 rubles. per sheet. Inexpensive drywall will save on repairs, but you need to understand that when buying cheap material, you should not rely on high quality products. After all, the quality of any building material directly depends on its price. You can buy drywall in sheets with high quality standards from 230 to 250 rubles. per piece

As mentioned above, the price of this finishing material also depends on the manufacturer's company. For example, the price of Knauf drywall is somewhat higher than in the case of other brands. For example, the cheapest sheets from this German manufacturer range from 220 to 240 rubles. per piece More expensive GKL from the KNAUF brand can be purchased for 300-340 rubles.

Profiles for drywall: sizes and prices

Today you can meet different profiles under drywall. The size and cost of these products also vary. The thickness of the metal profiles from the German manufacturer Knauf ranges from 0.5 to 0.8 mm. The ability to choose different thicknesses allows you to assemble frames that can withstand the required weight.

Useful information! Profiles for drywall are equipped with anti-corrosion protection by means of galvanizing at the production stage. This procedure allows you to enhance their strength properties and extend the service life as a whole.

Profiles can be different design, which allows you to perform building models of any configuration. Depending on the design features, all profiles are divided into several varieties.

Length of profiles of different types:

Product name	Length, m
rack	2–6
guide	2,5–6
Ceiling	2,75–4,5
Arched
Angular	until 6

Rack profiles: description, use and prices

In the international nomenclature of building materials, such products are designated by the Latin letters CW. Such profiles are most often used for the installation of metal battens. Metal battens are needed to fix the plasterboard on false walls or ceilings.

The algorithm for using rack profiles is as follows:

1. First of all, the rack-mount strips are inserted into the guides, which are fixed along the perimeter of the false wall (or ceiling).
2. Next, the profiles are aligned in the desired plane.

The structure made of profiles is the basis for further installation of the GKL. Planks, which are of the rack type, are produced in a width of 60 mm, and their height is 27 mm. The length of the rack bar can be different (from 2 to 6 meters).

If the length of the bar does not correspond to the specified goal, then it is possible to combine two or more bars into one profile. Docking of individual slats is carried out with the help of special fixing elements. If desired, the strips can be connected in such a way that they are perpendicular to each other.

Such profiles may have different markings, depending on the manufacturer. Marking of rack slats can be as follows:

• CD (Knauf);
• PP (Giprok).

The price of a profile for rack-mount drywall varies from 150 to 400 rubles per package. The range of prices is due to different brands of products, as well as dimensions. Packages most often contain a standard number of parts (12 pieces).

The average cost of rack profiles:

Profile size, mm	price, rub.
50x50x3000	190
75x50x3000	240
100x50x3000	290
50x50x4000	279
70x50x4000	325

Guide profiles

This type of profile has the international designation UW. These products are produced in the shape of the letter "P". From the name we can conclude that such products are used as guide elements. When assembling the frame structure, racks or guides are fixed to them, after which drywall is installed. Prices for guide profiles vary depending on the length of the product.

The guide bar is 28 mm wide and 27 mm high. The guide rails are fixed to the work surface using dowels. The length of the guide part can be different (from 2.5 to 6 m).

Average cost of guide profiles:

Profile size, mm	price, rub.
28x27	105
50x40	175
65x40	210
100x40	275

Ceiling and arched profiles

International designation ceiling profile-CD. Ceiling strips are used for quick assembly of frame structures, which are fixed to the ceiling and then sheathed with plasterboard.

The thickness of the ceiling strips varies from 0.45 to 0.55 mm. The standard length of the ceiling profile is 3 m. The most common ceiling strips with dimensions of 60x27 mm.

The average cost of a ceiling profile:

A variety of arched planks differs from the rest in that they have a curvilinear shape. Arched planks are used to organize arched openings and other structures that have a complex shape.

Such products are marked with Latin letters CD and UD. When mounting such parts, it is possible to bend them along the required radius. This possibility is realized due to the fact that the body of this type of profile is supplied with holes and cuts at the manufacturing stage.

In the building materials market and in specialized stores, you can often find ready-made (curved) profiles. The bending radius of such a profile can vary from 0.5 to several meters, and the length from 2 to 6 m. Profiles of this type have a fairly wide range of prices. You can buy a profile for arched drywall for both 30 and 200 rubles. Here plays a very important role design feature details.

Useful information! It often happens that a profile with the required radius is not found on sale, and even straight arched notched models are not available. In this case experienced craftsmen it is advised to make notches on a regular profile and make a bend of the desired radius yourself.

Corner profiles

Products of this type are divided into two types:

• protective;
• plastering.

The first type of corner strips is used to provide protection for outside corners. drywall constructions(for example, in doorways). Fixation of the corner strip is made by plaster, which penetrates into the holes of the profile and securely fixes it in the required position. The second type is also called beacons and is used when plastering walls.

The cost of popular models of corner profiles:

Product size and name, mm	price, rub.
Perforated aluminum corner profile, 20x20, 3000	27
Corner profile galvanized mesh 35x35, 3000	39
Corner profile white pvc, 30x30, 3000	63
Protective corner profile, 31×31,3000	129
Corner metalized on paper basis for internal corners, 3050	260

As a rule, when assembling drywall structures, experienced craftsmen try to use materials from one company. For example, for fastening gypsum plasterboards, Knauf brands acquire Knauf profiles for drywall, of which there are many types and sizes. It makes no sense to use expensive drywall, but save on the profile, because the durability of the entire structure depends on the quality and reliability of the parts for the frame. And in order not to exceed the budget limit allocated for repairs, you need to carefully calculate the amount of materials, choose optimal size sheets to minimize leftovers.
