Skylights as an alternative to windows - types and features of installation. Use for ventilation and smoke removal from rooms

Roof windows in the form of zenith (light) lamps are mounted in the roof plane and provide natural light penetration into the dwelling under the roof. They also serve for ventilation when a mechanism for opening the entire structure or part of it (sash) is provided.

The difference from standard skylights is that skylights have a convex surface (dome). This allows them to let in more light.

Anti-aircraft lamp can be made in the form of a hemisphere or pyramid. Its frame is made of metal (usually aluminum), plastic or wooden elements.

The design of the lantern includes a supporting frame, which is designed to be installed in the opening on the roof. Usually it has a border that allows you to fix the frame.

Previously, the main material for the transparent part of the lantern was the usual window glass, now more often installed acrylic glass or polycarbonate. They are resistant to mechanical damage and better hold the load. A significant disadvantage is that these materials are easily scratched and abraded, which can reduce their ability to transmit light.

Some lanterns have a device for opening. Devices can be mechanical or electrically driven. Electric ones can be equipped with a remote control.

You can install the skylight yourself, but it is better to use the services of a master, especially considering that the work will be carried out at a height.

First, an opening is made, it is better to provide a place for it even during construction. In this case, damage to the rafters and other structural elements of the roof must be avoided.

A so-called mounting glass is mounted in the opening. This design serves to securely fasten the frame and the rest of the rooflight structure. The glass is insulated and insulated from moisture penetration. For this you can apply different materials, for example, bituminous mastic and polyethylene.

A frame is mounted in the glass. During installation, cracks should not be allowed, places where water can then begin to penetrate. Better if the frame is equipped rubber seals. Many manufacturers immediately put them in the manufacture of the structure.

If the opening of the lantern or its flaps is not provided, then glass construction Attaches directly to the frame and installs with it. If it is possible to open the lantern for ventilation, then the glass part is mounted later on an already fixed frame, using hinges.

The final stage of installing a skylight is fitting fittings and connecting a remote control.

Previously, such structures were rarely used, since skylights are installed on a flat or slightly sloped roof and could not withstand snow or rain loads due to low strength. With the advent of new materials, the risk of fracture has decreased.

The most common and most functional form anti-aircraft lamp - a hemisphere. This shape allows you to withstand significant loads, does not allow, for example, snow to accumulate on the surface, as well as the formation of condensate from the inside, provides water runoff.

In general, the forms of anti-aircraft lamps are very diverse. It can be a dome, a pyramid, an arch, or more complex structures, depending on the style of the house, lighting needs, etc.

The glass of the dome of the lantern can be used plain, but it can be used frosted, to obtain diffused light, colored, with a coating that does not transmit ultraviolet, etc. A film with a printed pattern can be used for coating.

Antiaircraft lamps not only serve for illumination, but also are an active element of design both outside, and from within the room.

Skylights are light openings on the roof of a building that have nothing to do with artificial light sources. In large rooms, they are the glazing of a domed roof, and in a small private dwelling, they are a single roof window.

Glazing can be of various configurations and types, so it easily fits into the architectural ensemble of the building and gives it a certain zest not only from the outside, but also from the inside.

Antiaircraft lights on flat roof

Types of lanterns by configuration and purpose

By type, anti-aircraft lights are divided into point and tape. Separately, it is worth highlighting the dome structures, which are also classified as point structures.

Light pyramids on the roof

Affordable Spot Lighting

Small light openings can be afforded by almost every owner of a private house. Suitable for bedrooms, kitchens, bathrooms, winter garden, attic. Shapes can be very different: square, circle, rectangle, dome, pyramid.

It is not surprising that a non-standard choice is primarily made by someone who wants to save on electricity for lighting a room. In addition, natural daylight does not harm vision, unlike artificial sources, moreover, the effect is visually created. open skies- the weather condition will be reflected in the room - sunny or cloudy.

Spot window on a flat roof

Manufacturers of window structures produce ready-made roof windows - double-glazed windows with a sealing contour, protection against moisture and cold bridges. The easiest way to install a double-glazed window is at the stage of building a house.

Classic dome or transparent roof

Dome skylight

There are no standards in the manufacture of skylights, which opens up great opportunities for design and practical side of the issue. The domed glazed structure looks like a multifaceted or rounded superstructure made of glass, polyester, acrylic or polycarbonate that tops the roof of a building.

The dimensions here depend on the need, for example, in a private house the structure will be smaller, while for shopping center or you need a pool big square(this may be several points).

Tape structures of rooflights

Tape skylights, as in the photo below, are practically not used for private housing construction, as they are designed for large long rooms. Such structures can most often be found in production workshops, hangars or warehouses, that is, where ordinary windows are simply ineffective due to too much inner space.

Tape structure on the roof of the production hall

The advantage of a transparent glass strip on the roof of a building over conventional, even large side windows, is obvious - sunlight penetrates from above, regardless of the time of day - it is not covered by the opposite part of the building. If a Sun rays To be more precise, UV radiation is undesirable, it is possible to install UV protection in the form of panels with a special film.

The effect is also felt in ventilation - hatches are installed at the top according to the principle of vents, which can always be opened at the right time manually or automatically. According to the laws of physics warm air rushes up and takes with it all the smells into the atmosphere through open passages. If necessary, additionally install exhaust fans.

Long-term observations, confirmed by scientific research, have shown that at enterprises where daylight, productivity increases, and employees do not often take sick leave.

Considering this factor plus the reduction in electricity costs for lighting fixtures, such a solution is very beneficial for the employer.

Use for ventilation and smoke removal from rooms

Skylights are used to ventilate the room and even to remove smoke.

roof glazing for industrial enterprises and in shopping centers most often provides just such tasks. But this is not a standard or rule and is considered as an auxiliary function that can be used in a private home.

In most cases, ventilation hatches open electrically, and sometimes there is a sensor for automatic adjustment. For high rooms, this is extremely convenient - you do not have to specially climb onto the roof to raise the sash, and then climb again to close it.

Hatch for ventilation production shop

Smoke exhaust system at the enterprise

Hot (warm) air, rising up along with smoke, exits through the open sash of the ceiling window into the atmosphere, after which the sash is closed by the operator or automatically. Such a function, provided on the roof of the building, allows you to do without a supply and exhaust ventilation system, or to use such units of lower power.

Anti-aircraft lamps for smoke removal with forced ventilation are very convenient in terms of fire safety– during a fire or released carbon monoxide life-threatening. Here you will need temperature sensors that react to temperature and smoke - they give a signal to the electric drive and the roof sashes automatically open for ventilation.

Installation of anti-aircraft tape and dome lights

The functionality of light openings largely depends on the material from which they are made, usable area and how they are mounted on the roof. But be that as it may, here it is necessary to take into account not only the need for free daylight and ventilation, but also in the quality design of the structures.

Glazing materials and their properties

Glazing requires transparent or tinted materials that are able to retain heat in the room:

• monolithic sheets of polycarbonate or acrylic;
• cellular polycarbonate;
• polyester boards;
• glass, double-glazed windows, triplex.

Cellular polycarbonate of different thickness

Acrylic, as well as monolithic and cellular polycarbonate, are significantly ahead of glass in terms of strength characteristics, exceeding them by 200-250 times! Most modifications of such panels are fire resistant, which in some cases can be decisive when choosing materials.

To install skylights on the roof, sheets with UV protection are usually used.

Both polycarbonate and acrylic are very easy to mold and therefore very easy to install. They also have one more feature - from such panels you can make convex (curved) surfaces. But cellular polycarbonate with inclined partitions (triangular section of cells) is used only for flat planes.

Dome structures made of polyester plates

But polyester structures, in addition to resistance to high temperatures and mechanical (impact) strength, have protective properties to ultraviolet radiation without additional coating. But there is serious shortcomings, it is a non-uniformity of color, resulting in low transparency, and a high cost compared to polycarbonate and acrylic.

In some cases, transparency is contraindicated and then polyester plates are used.

Transparent triplex is always in demand

Glass has three main qualities that do not change over time, these are:

1. The highest transparency.
2. Resistance to abrasion from dust and sand.
3. Resistant to chemical processing.

The main disadvantage of glass is its fragility, but when glazing with double-glazed windows or triplex, this disadvantage is compensated to some extent. Another disadvantage is the mass, which requires more solid foundation(frames) compared to polymers.

Requirements for the installation of anti-aircraft tape and dome lights

For the installation of rooflights, almost any type of roof can be involved:

• profiled or rolled steel decking;
• ceramic, bituminous and metal tile;
• reinforced concrete slabs or membranes.

The main requirement is the stability and rigidity of the structure, which, in principle, are reinforced concrete floors and truss systems.

Such glazing is done for different purposes, therefore, this factor should be taken into account when designing. This includes the area of ​​individual sections and the entire structure, the degree of transparency of the material and its protection from ultraviolet radiation, the need for a mechanical or electric drive.

Assembly team installs lights on the roof

Randomness during installation is unacceptable, since the location of the rooflights is very clearly visible from below, from the room, which means that the structure must have correct location and clear contours. If the building provides for heating, then it is best to use cellular polycarbonate or double-glazed windows - such glazing retains heat as much as possible.

Also, insulation is necessary for supporting metal circuits, which is usually achieved using various heat-insulating seals. When designing and installing, strictly horizontal arrangement of sections is avoided, making them inclined or convex - this configuration contributes to a more rational distribution of the light flux and does not delay the snow cover.

When designing, one should take into account the possibility of condensation, which should not be, therefore, insulation is very important here.

The height of the structure is also taken into account - it must rise above the roof by at least 30 cm.

Mistakes and misconceptions of some customers

Lanterns with 100% transparency

Antiaircraft lamps in Russia and countries former USSR are not very common, so it is not surprising that customers are cautious and even somewhat distrustful. And here are the most common examples:

• in winter time such a construction on the roof is useless, since it is almost completely covered with snow. In fact, due to the slope or rounding of the surface, which rises by 30-60 cm, the snow cover is blown away by the wind. The most important thing is that the height of the snow cover does not exceed the height of the lantern;
• gable or U-shaped structures are more reliable. But the most effective is a rounded, arched shape, since, firstly, it occupies a smaller area and, secondly, it resists the wind better and precipitation falls off it faster;
• can be used cheap materials. Ultimately, low cost affects quality, which over time can lead to the need for repairs. After that, the total cost will be more compared to high-quality material that could be selected immediately.

Illuminated skylights - inside view

In conclusion, skylights and domes for ventilation and/or daylighting are complex designs from a technical point of view.

However, in some situations, it is the best and most economical option when constructing a building. The costs pay off very quickly, and this can be confirmed by those who have already decided to upgrade.

Video: Installation of a skylight

Antiaircraft windows are intended for installation in flat roofs. They make it possible to illuminate rooms with small areas facade glazing and those in which there is no possibility at all to make windows in the walls.

Previously, for additional lighting of rooms, rather simple anti-aircraft lamps were built, consisting of a metal frame and glasses inserted into it. It was desirable to make such structures deaf, since the slightest gaps in the junctions created a risk of leaks. Another problem with old skylights is the high thermal conductivity, which caused houses to lose too much energy through the glazed roof.

To date, the requirements for thermal protection are high and continue to grow, so the installation of "cold" windows is not only a wasteful solution, but also prohibited at the legislative level in many progressive countries. Modern anti-aircraft windows successfully cope with the problems of hydro and thermal insulation. Thanks to the seals, their sashes can be opened and closed without the risk of leaks, and a two- or three-chamber double-glazed window filled with an inert gas ensures high level energy efficiency.

Features of the design of anti-aircraft windows

A standard flat roof window consists of a profile with double-glazed windows protected from above. dome acrylic or polycarbonate. Latest material it is preferable, as it has greater impact resistance, resistance to weathering and temperature changes. The streamlined shape quickly runs off rainwater, snow does not linger on it. An air layer is formed under the dome, which contributes to the preservation of heat, in addition, it provides additional noise protection.

The resistance of windows to unauthorized entry into the house is increased through the use of durable tempered glass or triplex. The latter consists of two glasses glued together with a special transparent film without interfering with the view. If such glass breaks, the fragments will not fall down into the room, but remain glued to the film. When tempered glass breaks, it shatters into many small, blunt, relatively harmless pieces. Increased protection against burglary is also provided by additional fastenings of the profile to the roof structure.

The profile can be made of coated wood or high quality plastic (PVC) reinforced with metal. Most often, a multi-chamber PVC profile is used, the internal voids of which are filled with air or, in the case of choosing windows with increased energy efficiency, with insulation. The characteristics of a double-glazed window depend on the number of chambers in it (the more there are, the higher the heat-saving properties of the structure) and the features of the glasses. Usually standard glasses are used, but if increased impact resistance is needed, the already mentioned triplex and tempered sheets are used. The chambers between the glasses can be filled with air or an inert gas (usually argon or krypton), which has a low level of thermal conductivity.

Today, in addition to dome structures, manufacturers also offer innovative flat-surface windows. They are similar to mansard roofs, but they have qualities that allow them to be mounted in a horizontal roof (with an angle of inclination from 0 to 15 °). Their main difference lies in the special technology of glass gluing, which provides increased strength and tightness of the structure.

Sizes and colors of skylights

Standard windows for flat roofs produced in sizes from 60 × 60 to 120 × 120 cm. In addition to square models, rectangular ones are also available, for example 90 × 120 and 100 × 150 cm. Among the high-tech windows with a flat surface, there are also larger options, such as 120 × 220 cm Some manufacturers also offer custom made windows. This option is more expensive, but the service is in demand, since there is a need to change old skylights with low energy efficiency to innovative "warm" designs. On request, it is also possible to make windows with frosted glass, rather than standard transparent glass.

Some manufacturers, who are especially concerned about the design of their products, offer a wide range of color scheme window frames. As a result, you can choose products that merge with the color of the roof, or, conversely, stand out in contrast against its background.

Sloped windows in a flat roof

In addition to special products, there are systems that make it possible to illuminate rooms under flat roofs using conventional skylights. Manufacturers offer ready-made frames made of OSB, glued wood and metal, in which you can install slanted windows standard sizes. The slopes of these structures are filled with windows, and the gables remain deaf. Usually, manufacturers make gables from OSB immediately with insulation, so subsequently they only need to be plastered and painted in the desired color.

According to one of the popular definitions, a brand is something associated with a stable and mass consumer idea of ​​a particular product. From this point of view, it is difficult to talk about brands of rooflights: they are too diverse and vary too much depending on the requirements of the customer.

Nevertheless, there are several world-famous firms specializing in the production of anti-aircraft lamps, the quality and style of work that allows us to speak of them as owners of brands in this area.

Velux

And the Danish company Velux should rightfully be the first in this row. Its founder Willum Cann Rasmussen is considered the inventor of the roof window - in fact, the prototype of the skylight. The name of the company itself is derived from two words: Ventilation (“ventilation”) and Lux ​​(“light”). It was founded in 1942 and is one of the largest manufacturers building materials in the world.

The company's factories are located in 11 countries, sales offices - in 40. The Russian representative office of the company is located in Moscow.

Velux skylights look like a flying saucer

Anti-aircraft lamps "Velux" are focused on the glazing of private cottages, residential buildings. Appeal to a person and his specific, personal interests is the credo of this company.

In the Russian Federation, the company's products are popular in all climatic zones- from Krasnodar to Murmansk. Velux skylights are characterized by good adaptation to Russian conditions:

• glass body (hereinafter, in accordance with the terminology established in the Russian Federation, we will refer to the “glass” as the parapet above the roof of the building, on which the translucent structure of the lantern is installed) is insulated with polystyrene foam;
• glass frame is made of PVC profile, including with single-chamber or double-chamber glazing;
• plexiglass, triplex are used as a translucent element. Options with frosted glass are possible;
• there is an option - pleated curtains;
• the sash is completed with a convenient handle for opening or an electromechanical drive with a remote control panel for opening the lantern and curtains;
• the lantern itself has an elegant appearance, the outline of a "flying saucer".

View of the Velux skylight from below

Prices for Velux skylights high. Judging by the price list of the Avrora trading house,

• blind anti-aircraft window 600x600 mm costs 15,000 rubles;
• the same, but 600x900 mm in size - 16500 rubles,
• 1000x1000 mm - 20600 rubles.

Opening lanterns of the same size cost 45,000 rubles, 46,600 rubles, respectively. and 51300 rubles.

The largest lantern - 1200x1200 mm - costs 24,600 rubles. in a deaf version and 56,000 rubles. in the opening version. Prices for pleated curtains start at 9 thousand rubles.

Caoduro

Strip skylights Caoduro series 035 FX

The Italian company Caoduro is the second most famous and, perhaps, the first in terms of scope of activity, the subject of the anti-aircraft lamps market. It has been on the market since 1951. The glass structures of this enterprise are well known to Muscovites. This is the roof glazing of the expo center on Krasnaya Presnya, the air hotel in Domodedovo, the Molodyozhnaya hotel, the Atrium shopping center and many private houses and cottages.

Caoduro skylights can be divided into two large groups.

The first is extended (“ribbon”) rooflights for large roof glazing industrial premises and trade pavilions: arched structure series 035FX, gable series 045FX, translucent structures of the S series. These are modular-type structures, their production is put on a serial basis. May be supplied with mechanical or electrical devices for opening sections up to 14 m long.

Dome skylight series Vela

An interesting idea was the use of energy solar panels to ensure autonomous operation of the mechanisms of anti-aircraft lamps. Batteries are built into the flashlight itself. The system can be equipped with touch sensors that control the opening and closing of the lights depending on weather conditions.

The second is domes for local lighting.

These are the lanterns Diamante and Vela, made by thermal stamping from a monolithic sheet of polymethyl methacrylate or polycarbonate with clearance dimensions from 45x45 cm to 200x200 cm (or corresponding diameters).

Dome skylight Caoduro

These are large temple-type domes on aluminum profiles, a typical example of which is the roofing structure of the megamall MEGA I.

Self-supporting domes with a diameter of up to 8 m, made entirely of translucent materials, without the use of profiles, are considered a unique development of the company. "Cold" and "warm" versions with a single or double wall are available.

Although the Italians themselves consider the uniformity of illumination to be the main advantage of these domes, it must be said that the appearance of these structures, which have an absolutely fantastic appearance, makes a greater impression.

The Russian representative office of the company has its own website http://www.caoduro.ru, where you can specify the parameters standard projects, deal prices for skylights or order a calculation of the cost of construction.

schuco

Skylight dome Schuco

Skylights "Shuko" - the result of the use of profiles of the world famous window company Schuco in roof glazing.

Aluminum and steel profiles are used for mounting skylights Schüco FW 50+WI, Schüco VISS TVS, AGS 150, which allow you to create three-dimensional structures of a pyramidal, dome-shaped shape, double-slope and single-slope lanterns. Possible glazing tinted or stained glass, triplex.

In Russia, Schuco cooperates with companies "Deutsche facade", OOO "Continent Group", next to others.

Schuco profile systems are often used for large-scale glazing in " mediterranean style". Those. for the construction of the roof of the whole building in the form Egyptian pyramid, Romanesque dome, etc.

Due to the scale of objects, the relative prices for anti-aircraft lights "Shuko" may seem relatively modest. There are cases when 1 sq. meter of the dome cost about 7500 rubles.

Lamilux

Sectional view of F100 Glass skylight

Another German company specializing in the production of roof glass structures is Lamilux Heinrich Strunz GmbH- was founded in 1909. It has its own representative office in Moscow. In the Russian Federation, it specializes in glazing, primarily, industrial facilities and large trade and exhibition pavilions. The most famous works are Lamilux skylights on the LexusRolf pavilion and the Astrophysics building in Moscow, on the roof of the MLP technopark in Lyubertsy and a number of other objects.

Main product types: lantern for local lighting F100 and its modification F100 glass with double glazing, pumped between the glasses with argon and a three-stage seal. The design is designed for use in Russian cold weather.

Skylight Lumilux FE

Another advantage of the F100 family of skylights is that these products can be delivered to the installation site assembled and installed in a matter of minutes using a well-thought-out system of flanges and mounting brackets.

Unlike the F100, whose glazing has a convex shape, rooflights of the family F.E. flat, with a glass inclination angle of 0 or 3 degrees. The glass of the lantern is made of fiberglass and can have a square or round shape and be completed with more than 10 types of double-glazed windows.

Skylight Lumilux FP series

Anti-aircraft lamps series FP and RW have a pyramidal configuration and the shape of a gable "loft", are formed by an aluminum profile.

For workshops, pavilions, exhibition halls, Lamilux is ready to supply extended “light strips”: arched type B and gable type S.

All of the listed designs can be equipped with mechanisms for manual or remote opening, smoke extraction systems, etc. options.

Glazing Lumilux PR 60

Profile systems PR60 and PR 60 EnergySave allow to produce glazing of the entire roofs and adjoining parts of the walls of buildings. The basis of the design is a stainless steel profile.

PR 60 EnergySave is characterized by increased heat-shielding properties. According to expert estimates, the heat transfer resistance coefficient of this structure exceeds one. It is possible to install solar panels, glass coated with precious metals.

Get help about prices for Lamilux products is conditioned by the provision of information about a specific object for calculations. But there is reason to believe that flashlights of the F100 and FE series are offered to corporate clients at prices ranging from 12,000 to 24,000 rubles.

AWAK

Polish manufacturer of skylights AWAK - Icopal Group positions itself as the world leader in the manufacture of skylights with smoke extraction systems. True, these systems do not represent any special tricks: pneumatic or electric drives for opening roof hatches, combined with systems fire alarm. Smoke extraction is natural.

Anti-aircraft lamp AWAK on the roof of the Logistics Center in St. Petersburg

By themselves, the designs of AWAK anti-aircraft lights are quite trivial. Judging by the photo gallery on the company's website - mainly arched options"tape" glazing on a low glass.

AWAK has been on the glass construction market since 1999. It cooperates with a number of large Russian enterprises in the construction industry. Among them "Stroykrovkomplekt", Diacon, ET Group and etc.

The company's achievements include participation in the glazing of the Logistics Center in St. Petersburg, the implementation of large projects in Sweden and a number of other countries.

Not to be confused with American company AWAK Technologies, which designs and builds dialysis machines.

"Leron"

Antiaircraft lamps Leron

Trading house "Leron"- a purely Russian enterprise. Formed in 2005 It has an office in Moscow and a production complex in Tula. It offers strip (in the form of a long strip of glazing on a low glass) skylights up to 6 meters wide in arched and gable configurations and “spotlights” for local illumination of premises and smoke removal in case of fire.

All types of Leron skylights are equipped with electric, or pneumatic, or mechanical drives for opening / closing the wings and a control system from the Italian company Aprimatic.

Antiaircraft lamps Leron

Among the most famous works of Leron are the glazing of the garages of the Administration of the President of the Russian Federation, the Russian Cardiology Research and Production Complex, the Vnukovo shopping center and many others.

Prices for spotlights "Leron", depending on the height of the base:

• With dimensions of 1x1 m - from 20224 to 20757 rubles;
• With dimensions of 1.5x1.5m - from 26139 to 26936 rubles.

Prices for tape anti-aircraft lights "Leron":

• 1.5x6.0 m - 55050 rubles,
• 2.0x6.0 m - 67100 rubles,
• 3.0x6.0 m - 84397 rubles. including VAT - 18%.

It is easy to see that the prices of "Leron" are not much different from the prices of leading foreign manufacturers of anti-aircraft lamps.

Antiaircraft lamp with the bearing translucent design Caoduro

The list of companies presented here can hardly be called a rating of manufacturers of anti-aircraft lamps - the listed enterprises are too incomparable in terms of types, types of their products, and their application. Nevertheless, this article fairly accurately reflects the place of the main players in the "glass and roof" business in this industry, and the role in its development.

It should be added that the actual work on the installation of rooflights can only be carried out by enterprises that are members of SROs: self-regulating construction organizations. Details about the work of participants in such organizations, including in the field of manufacturing and installation of anti-aircraft lamps, can be found on the website of SRO engineers.

Problem low light attic space traditionally solved in two ways: the installation of electric lighting fixtures and the installation of skylights. Artificial light is convenient, but the constant presence of people under its influence leads to a deterioration in vision. Through skylights passes a lot of natural light, but their use is possible only on pitched roofs above 15°. VELUX has created zenith window(also called a skylight), solving both problems at once.

What is a VELUX skylight

The main design feature of the Danish zenith window is installation on roofs with a slope of 0-15°. No dormer or attic window is able to work effectively and for a long time under such conditions. Precipitation from them drains badly, snow remains until spring, dust turns into a crust and lies forever.

A completely different matter is the anti-aircraft window, which makes company VELUX. The innovative translucent design consists of two elements - the actual window and a transparent dome.

The window frame and frame are made of PVC profile. A double-glazed window with a noise-absorbing effect is made using the triplex technology - a tight connection of glass and a transparent durable film. If the glass is applied swipe, it will crack and remain in place, its fragments will not fall down. The triplex film filters out up to 90% of UV rays, without interfering with natural light, but preventing the interior from fading.

The inner glass has a heat-reflecting coating. zenith windows more energy efficient than standard ones. The glass on the outside of the package is tempered shockproof.

zenith windows are issued deaf and opening. The second option is equipped with an electric drive that raises the sash for ventilation to a height of up to 9 cm. The package includes a remote control. The opening window is also equipped with a rain sensor (optional), which gives the command to close when the first few drops fall. The remote control is programmed for regular airing at certain hours or at a specified time interval.

The convex dome with a rise of 15 cm is made of durable acrylic. Its edges are hermetically fixed on casement and do not interfere with opening it for ventilation. Available in clear and opaque polymer options. A window with a transparent dome is completed with a pleated blind with a selection of 4 color solutions. The curtain is also controlled from the remote control.

The dome protects flat glass from mechanical damage and precipitation retention. Water quickly drains from its protected surface, snow crumbles. The dome does not require frequent maintenance, which can be carried out as part of a comprehensive roof service.

In cold damp Denmark, not rich in sunny days, the sale of Velux skylights is very active. According to regular studies of the manufacturer's laboratory, the owners give exclusively positive reviews about these translucent structures. In particular, they note:

• gain natural light;
• extension of the time of natural light;
• the ability to adjust the brightness of the lighting;
• increased ventilation and improved microclimate;
• simplicity and ease of window and curtain control;
• saving electricity for artificial lighting;
• maximum energy saving and economy of heat carriers;
• excellent noise-absorbing characteristics;
• reliability of the mechanism and electrical equipment;
• strength of glass and dome;
• construction quality.

The VELUX window catalog offers homeowners a choice of 9 standard rooflight sizes. The price of products consists of the size and configuration of the translucent structure.

Benefits of installing Velux skylights

These windows can:

Tip: if you complete broken roof windows different types, use all designs of the same brand.

VELUX skylights can be used to install VELUX roof windows:

• with a central axis;
