How to properly install a skylight. How to install a roof window with your own hands? How to install a roof window

A very popular space. The space, which was a dark cold attic, thanks to the alteration and insulation becomes a full-fledged room, its lighting can be provided not only by the windows on the pediment, but also on the slopes of the roof. Installation of such a light source is quite complicated, but, wanting to save money, homeowners with little experience working with construction tools trying to do it on their own. Right choice and installation skylights with their own hands, in compliance with technological standards, they will provide high-quality thermal insulation and the absence of leaks.

Basic installation rules

1. The roof window is fastened not to the roof sheathing, but to the rafters.
2. The distance from the window opening to the rafters should not be less than 3 cm.
3. The lower part of the window is preferably placed on a horizontal beam.
4. The roof window sash is put on after installing its box.
5. Window insulation required.
6. Correct installation increases illumination by 40%.
7. The tightness of the window is of great importance, since it has a high load from atmospheric precipitation.
8. The window frame is selected according to the type of roof.

Window types

The window in the attic can be placed vertically, with the obligatory device of a separate roof, and obliquely - in the roof slope. Window frames can be made from hardwood, plastic or aluminium.

• Rectangular windows for attics are produced with a swivel frame, blind construction is made to order.
• The design of an inclined and a vertical window allows, when opening both, to go out to the balcony.
• Composite window: its upper part is movable, and the lower part is deaf, it serves to increase the area of ​​illumination.

When the roof slopes are very steep and it is impossible to view the surroundings through the skylights, vertical structures are installed under them.

What does the package include

The attic window device is more complicated than usual, its design includes:

• Roller shutters or awnings used to provide outside blackout.
• Salary that protects the window structure from the effects of precipitation.
• Frame and double-glazed window filled with inert gas.
• Sealant used for waterproofing.
• Internal slopes.
• Drainage chute.

Choosing a place for a window structure

The specifics of the location of the roof window requires taking into account some nuances: the width of the structure should be less than the span between the rafters, if you want to get more light, then you need to install several windows. The installation height should provide the ability to control the sash with a handle, its average value is 80–130 cm.

Installing a window opening above the radiator will eliminate the appearance of frost.

The slope angle of the slopes also affects the placement of windows; on a sloping roof, they are located higher.

Installation

Before you install a roof window, you need to mark the place for it. It is made from the inside. 3 cm retreats from the rafters, the lower limit of the window is outlined, an additional 9 cm is deposited for a roof with a high profile and 6 cm for a flat one. Having marked the upper limit corresponding to the height of the model, we mark up another 7 cm. The waterproofing sheet is cut with a margin of 20 cm and wrapped inside. If the roofing has already been installed, it must be cut off, and the crate is also removed.

In some cases, you can install it like this:

In the lower part of the opening, a beam oriented horizontally is nailed, in the upper part - a bar parallel to the crate.

Above top bar a factory drainage chute is attached to drain precipitation, it is installed at a slight angle. If such an element is not included in the kit, its role can be played by the design of the waterproofing strip.

In order not to damage the glass and fittings during installation, it is recommended to remove the sash. Next, the frame is assembled according to the manufacturer's instructions. IN drilled holes the brackets included in the kit are inserted. A strip is attached to the upper part of the frame with a stapler mineral wool for warming. A strip of insulation is also attached to the mounting bar at the bottom of the structure. The frame is installed in the opening and fastened to the corners with self-tapping screws. The tightening of the upper fastener is not completed completely, leaving room for alignment.

Now the sash returns to its place and the uniformity of the gap is checked on all sides of the fit. After making sure that the sash is correctly installed, we securely fasten the screws in the upper part, and remove the glass again. The remaining parts of the waterproofing are fastened under the window seal with brackets, a waterproofing apron is laid out around the window, the top of which is wound under the gutter.

Salary setting

Work on the installation of parts of the salary begins with the installation of a corrugated apron under the window. After that, the side elements are fixed, which must be inserted into the lower part until it clicks. The top layer completes the process. All parts are attached to the frame with self-tapping screws and fit tightly together. Next, the roofing material is laid.

The time has come for the final installation of the sash in place, the roof window is installed.

In recent years, the installation of skylights has become widespread. This is due to the benefits that people receive by deciding to reconstruct the attic space and make it a place of comfortable rest.

A roof window is a structure that is installed directly into the roof. As a result of this, the attic turns from a dark and dusty room into a room filled with light, where you can retire from the hustle and bustle and relax.

Installation of skylights is possible with a roof slope of 12 to 90 degrees. Modern manufacturers in the manufacture of their products took into account such conditions as strong wind, high humidity, the possibility of use, regardless of the complexity of the configuration of the roofing system.

Installing a window requires a lot of responsibility, because compared to ordinary windows, it is exposed to strong atmospheric precipitation, as it is located on the roof of the house. Therefore, the installed structures must be strong, tight and durable.

Roof window installation price

We strive to make the cost of window installation for our customers as affordable as possible. We care about quality and guarantee that the structure we install will reliably protect you from rain, snow, wind and low temperatures. You can order turnkey work of any complexity from us!

The products of these companies are small differences. For example, for Fakro, the opening handle is located at the bottom, while for Velux, it is at the top. Choose Fakro when you want to place a window opening at the top, and Velux for a lower location.

On average, the price of the products of these two manufacturers is the same. Delivery is quite fast with no delays.

Owners who want to turn the attic over the bath into a functional living space need to take care of the free flow of flows fresh air and daylight. These tasks will be solved by installing skylights, the rules of which differ from the standard technology for mounting facade counterparts. If the owner of the bath decides to equip the windows with slopes, and not gables, the structure with a light-conducting element should become part of a multi-layer roofing system. The window must not only be securely strengthened, but also ensure that the technical characteristics of the roof are maintained, which guarantees a well-executed installation.

Tasks of attic window structures

The complex “pie” of the roof, built according to the rules, retains heat, does not accumulate condensate on the surface, and serves for a long time thanks to excellent under-roof ventilation. Equivalent duties are placed on the “fragile shoulders” of skylights, which, moreover, must open freely and not cause difficulty in closing. Windows along with the roofing system will have to repel atmospheric attacks. Therefore, it is recommended to equip the attic with special designs:

• with tempered glass or triplex glass;
• with an energy-saving light-transmitting element;
• with hermetic seals and overlays;
• with a durable frame protected from constant exposure to moisture and UV rays;
• with devices providing shading, easy operation, ventilation in summer and winter mode, protection against insects and dust suspension.

If you want to look at the projects of baths with an attic, we advise you to read the article

It is desirable that the use and care of them is not difficult, so that fogging and damp finishes do not irritate the owners. All requirements will be satisfied by the exact selection and perfect installation of skylights, carried out in strict accordance with the manufacturer's instructions and generally accepted technological standards.

Preliminary planning and calculations

Installation without calculations - money down the drain. In order not to have to spend money in vain, you first need to calculate everything, select windows in accordance with the tasks to be solved and the type of roofing material, and determine the place for their installation.

Glazing area calculation

The formula is extremely simple, the result depends on the floor area. Every 10 m² must be illuminated by 1 m² of glazing, regardless of the size of the window. There is a nuance that slightly corrects the amount of light entering through the attic window. The higher the window opening, the more daylight passes through it. However, too high a location will interfere with admiring surrounding nature and a similar installation is more suitable for flat roofs with slope angles of 15-20º.

Unspoken laws and architectural aesthetics force roofs with steep slopes to be equipped with windows, the lower line of which is on average from 1.00 to 1.40 m. The lower limit is 0.80 m, the upper limit is 1.90 m. Anyway total area translucent elements should be calculated according to the above formula, and one, four or two windows the owner will want - a choice based on personal preferences.

Which window to buy?

The buyer is now offered a lot of different designs with numerous functions, which are not worth listing in this article. The difference is not only in dimensions, but also in the mechanisms of action, in the location of the rotary axis and the window handle. The last characteristic affects the installation height of the window in the attic. The handle is too high - it is inconvenient to open if there is no remote control attached to the window, too low - it is dangerous if children are resting in the bath attic. In addition to the handle, as a point of application of constant effort, the type of roofing material affects the choice of window. The higher its relief, the greater the height should be at the outer window frame. Products with the Fakro brand, for example, have a special marking, according to which windows are selected for attics with tiles, ondulin, metal profiles or a smooth roll coating.

Usually, the factory equipment includes fasteners, mounting brackets, a waterproofing apron with a vapor-removing effect, special sealant and adhesive tape. Of course, it is better to purchase a complete kit with all the necessary accessories for installation. However, in the absence of insulation, waterproofing and a corrugated vapor barrier membrane, all this can be bought separately or made from the proposed hardware stores materials.

Important! The installation of a drainage gutter above the top line of the roof window is a prerequisite. If it is not included, you can make a gutter from a piece of waterproofing material folded in half.

It is difficult to say what initially needs to be decided by the owner of the bath, who wants to install dormers with his own hands. Determination of the installation site should be carried out in parallel with the selection of the optimal design. More precisely, these issues are solved in the aggregate.

Choosing a place to install windows

Location is an important factor that determines the service life of the entire roof, interior decoration and aesthetic data of the building. Before figuring out how to install a roof window, you should find optimal location for his device.

Valuable professional advice. No need to arrange window openings:

• on the slopes of the valley, as in the valleys formed by it inside corners precipitation will accumulate;
• near ventilation ducts, chimneys, the operation of which will cause condensation to form;
• near the junctions horizontal walls due to accumulation of precipitation and possible shading.

Professionals advise not to get involved in the proximity of any nodes of the roofing system at all.

The height limits of the opening under the roof window have already been mentioned. There are no clear technical guidelines on this matter, therefore it is impossible to say for sure what has more impact on the choice.

• Definitely the type of roofing material. Any soft roll variety can be cut anywhere. No tiles! It must be positioned so that the bottom line of the window structure is located above the row of “uncut” whole tiles.

Attention. If it is not possible to arrange an opening over a row of solid tiles, it will have to be disassembled, and after installation, cut or shaped elements should be laid over the window frame.

• A significant criterion is the pitch of the rafters. It is advisable not to violate the integrity truss system. It is recommended to buy windows, the size of which allows them to be freely installed between two adjacent rafters with a margin of 7-10 cm. The margin is necessary for laying a heat-insulating layer. If the pitch of the truss system is not sufficient for a large window, it is better to purchase and install two or three small ones side by side.

Note. If it is necessary to remove part of the rafter for window installation to increase the strength of the truss structure in window opening install a horizontal bar.

• Top or bottom handle. Roof windows with upper handles are arranged at a height of up to 1.10 m, with lower handles - at a height of up to 1.70 m.

The owner, who chooses a place for installation, needs to take into account that a heating device must be installed under the glazed structure, because the rational heating of the roof windows will eliminate the formation of condensate. This factor also affects the installation height. And one more thing: the buyer of remote-controlled windows needs to worry about cable routing.

Stages of window installation in the attic

The whole process of installing a window in the attic can be divided into a number of technological stages:

• preparation of the opening for the installed window;
• installation of a frame with a previously dismantled double-glazed window;
• laying of insulating material, waterproofing;
• fixing the factory gutter above the top line of the window structure or constructing it from a piece of waterproofing;
• installation and fastening of salary details;
• return to the place of the dismantled double-glazed window in reverse order;
• interior finishing with vapor barrier laying and slope construction.

The manufacturer's instructions describe in detail the installation of skylights: the owner of the bath, who does not have experience in this area, will be able to carry out the installation with his own hands, following the instructions exactly. We will only note the key points that may be left unattended. But taking them into account is a guarantee of a quality installation.

Opening device rules

• Since heat-insulating material is to be laid between the frame and the opening along the entire perimeter, an allowance of 2-3.5 cm must be left on each side of the rectangle, depending on the thickness and density of the insulation.
• Between the bottom line of the window structure and the roofing material, a technological gap must be left, the value of which depends on the type of roofing. For an attic with tiles, for example, you need to leave 9 cm.
• Between the upper mounting beam and the roofing material, 4-10 cm are left. They are necessary so that the window does not “skew” in case of shrinkage of the wooden truss structure.
• The window frame will be attached to the rafters or to special rails, fixed in level in a strictly horizontal direction. Reiki is made of timber with dimensions equal to the crate timber.
• WITH inside for waterproofing or existing finish draw an outline according to the calculated distances.
• Waterproofing is not cut out along the contour of the window! You need to cut it with a kind of “envelope” so that overlaps of 20-25 cm remain. The overlaps are then turned outward, fastened with a stapler to the frame or to the crate, and the excess is cut off. A waterproofing apron will be “put on” on top of them so that the insulating shell is completely sealed.

Specifics of window frame installation

Mounting brackets are attached to the frame according to the manufacturer's instructions. The window manufacturer Fakro advises dismantling the double-glazed window before fixing the brackets, the manufacturer Velux recommends removing the double-glazed window after fixing the brackets and “baiting” the frame in the opening. It is more convenient to lay and fix the heat-insulating material along the upper and lower lines of the window system and fix it with a stapler before installing the frame in the prepared opening.

Advice. Thermal insulation can be placed in the opening before the frame is installed and attached to the upper and lower mounting beams.

Frame installation and mandatory adjustment

• The lower brackets are fixed firmly, and the screws of the upper brackets are not tightened to the end. A slight play is needed for adjustment.
• It is during this period that the horizontals and verticals are verified, the adjustment is made with the help of plastic corners in case of deviations. Experts advise to temporarily put the sash in place to check how it will fit to the frame. No need to be lazy, after fixing the salary, it will no longer be possible to correct shortcomings and serious mistakes.
• The distances between the opening and the frame on the left and right must be equal.
• After adjustment, all fasteners can be tightened tightly, lay a waterproofing apron around the frame, attach thermal insulation along the side lines of the frame with a stapler.

To install a drainage gutter in the crate above the window, you need to cut two pieces, the size of which is equal to the height of the drainage device, and cut a piece of waterproofing according to these dimensions. The gutter must be led under the cut section of the waterproofing and attached to the crate. Note. The condensate drainage gutter is placed at an angle so that moisture does not linger, but spontaneously flows into the ventilation gap of the roof.

Completion of installation operations

The penultimate touch - the setting of the salary must thoroughly comply with the manufacturer's instructions. General rule: always start with the fastening of the lower element, and all the details of the salary are brought under the elastic seal. Then, in the reverse order of dismantling, put the frame in place. From the inside, a vapor barrier material is laid and the design of the roof window is performed by installing slopes.

Important. The plane of the lower slope must be set strictly horizontally, that is, perpendicular to the floor surface. The top slope must be perfectly vertical.

This is not a complete, but rather "detailed" list of nuances, according to which the installation of roof windows is carried out. More precisely, the article is a list general recommendations, which must be followed regardless of the specific features of window structures from a particular manufacturer. A strict rule is compliance with the installation technology attached to the product. It will help an independent installer to eliminate errors, and it will allow the customer to competently control the process.

Good day and interesting reading!

Who would have thought that one of our school losers at the next meeting of graduates would show himself from a completely unusual side.

According to his stories, he gave his parents luxury house and now he is building a bathhouse, and with an attic.

We talked with him, told him that you can make the attic more comfortable if you install slanted windows. He liked the idea and decided to apply to our firm.

This is how professional connections are made.

If you are interested in this idea, then I recommend reading useful information about the features of their installation.

Installation of skylights - instructions:

Depending on the roofing material used, architectural and thermal insulation conditions, skylights can be installed:

• at different depths (three landing levels): N (0 cm), V (-3 cm), J (-6 cm)
• on rafters or sheathing

1. Skylights can be installed in roofs with a pitch of 15° to 90°.

The installation height can be arbitrary, however, taking into account the operating conditions, the visibility and illumination of the room, as well as building codes, the windows must be installed so that the lower edge of the window is at a height of 170 cm from the floor level.

The installation height also depends on the angle of the roof and the size of the window.

2. The window must be installed above the tiles - there must be a whole, uncut row of tiles under the window.

If the roof is covered with profiled roofing material, the window must be installed at the recommended distance between the top edge of the roof and the bottom edge of the window.

In the event that the roof is at a considerable distance from the window, it is necessary to install an additional row of roofing material.

If the roof is covered with high-profile roofing material, it is necessary to cut or rivet the roof waves in such a way as to prevent damage to the lead apron of the flashing.

• under the window: 0-4 cm for flat roofing materials, with a planting depth J - 14 cm;
• 10 cm for low profile roofing materials;
• 12 cm for highly profiled roofing materials;
• along the window: 3-6 cm;
• above the window: 6-15 cm;

4. When mounted on rafters, the window is attached to the rafters using mounting brackets.

The distance between the rafters should be commensurate with the width of the window and can be 2-5 cm more (for example, for a window 55 cm wide optimal distance between the rafters is 57-60 cm).

Helpful advice!

In the event that the distance between the rafters does not correspond to the width of the window, it is necessary to change the roof structure.

At the same time, be sure to pay attention to the fact that the transverse beams are placed at an appropriate distance from the lower and upper edges of the window for proper interior decoration (above the window - horizontally, below the window - vertically).

5. Mark the location of the window installation on the hydraulic barrier. Cut a hole in the indicated place with a margin of 10 cm on each side, in order to then attach the hydro-barrier to the window frame.

Cut out part of the crate in the prepared place. To install the drainage gutter, cut out fragments of the counter-lattice and cut the hydraulic barrier obliquely.

6. Take out the aluminum profile-linings 1 and 2 from the window packing. Disconnect the lower profile-lining 3, as well as the transport wooden blocks from the window frame.

7. Remove the window sash from the window frame. To do this, you need to install the window with the bottom edge on the floor and tilt it easily. Open the window and turn the sash 150°.

While holding the window in this position, use a screwdriver to tighten the locking screws in the loops three turns clockwise.

8. Remove the sash from the window according to the indicated direction. Carry out this operation carefully while removing the sash from the hinges. Failure to comply with this requirement may result in damage to the hinges.

9. Screw the mounting brackets to the window frame at a distance of 10 cm from the edge so that they do not fall on the roof battens.

Outside the window frame, grooves are milled, marked with the letters (N, V and J) corresponding to different depths of the window.

Each groove corresponds to a certain type of salary. In the salary designation, the salary type (N, V or J) is indicated by the last letter, e.g. EZV 06.

Screw the mounting brackets to the box in such a way that the number on the angle ruler:

• corresponded to the thickness of the crate;
• coincided with the groove of the selected window landing depth.

The selected window seating depth (N, V or J) must correspond to the designation on the flashing package. Roof window installation solid crate carried out similarly to the installation of a window on the rafters.

10. Install the window frame in the prepared roof area. The mounting brackets must rest on the rafters. Check if the groove on the window frame coincides with the upper plane of the crate.

Using a level, check the horizontal line of the bottom edge of the window. If necessary, placing a wedge under the corner, set the horizontal. Screw only the lower corners to the rafters.

11. Insert the window sash into the window frame.

For this you need:

• take the sash in hand, i.e. outer glass towards you, and the bottom of the window up;
• holding the sash in a vertical position, insert it from the outside into the hinges evenly without skew;
• unscrew the locking screws three turns counterclockwise, and close the window.

12. Open the sash and check the parallelism of the gap between the sash and the frame at the bottom of the window. By placing a plastic wedge from the mounting kit under the upper mounting bracket from the side of the smaller gap, eliminate the non-parallelism.

13. Close the window and check the parallelism of the gap between the sash and the frame on the sides. If necessary, move the upper part of the box to the left or right to eliminate the non-parallelism.

Screw the upper corners to the rafters with screws.

Note!

If a hydro-barrier is used during the construction of the roof, it is necessary to install a drainage chute above the window.

14. In the event that a hydrobarrier is used during the construction of the roof, it is necessary to install a drainage chute in the prepared place above the window to drain condensed moisture away from the window, and also attach the hydrobarrier to the window frame.

15. Check the reliability of the window. In models with a ventilation device, the sieve must be opened completely.

ProfMarket is pleased to offer you to buy skylights at a price that is available to everyone from the best manufacturers, wholesale and retail.

If you are going to buy roof plastic windows, our company will offer best value and a wide selection, and our professional consultants will answer all your questions regarding products in the catalog of the Profmarket website.

Dormer windows are called windows, the installation of which is carried out directly into the roof.

At the same time, roof windows are needed not only to illuminate the under-roof space, but also to protect against atmospheric phenomena.

So, skylights are a constructive part of the roof. In view of this, they must meet all the requirements characteristic load-bearing elements reliability, strength, water resistance.

The main feature of the roof window is its location - in the plane of the roof. Due to its inclination, the fasteners of the structure experience an increased load, because they have to hold the window.

This window differs from the usual one in the way of opening - along the central axis, although today models with opening to the side and along the upper axis have already been invented.

These design features make it easy to clean windows and provide improved visibility. And with the help of unique fittings, the sash can be well fixed in any position.

Attic windows can be different shapes, which usually depends on the configuration of the roof, which allows you to repeat its curves and originality.

This is also helped by a universal mounting system and the availability of various configurations. Large light transmission and small window openings provide better lighting.

Especially for different regions suitable double-glazed windows were invented: for cold ones - multilayer, energy-saving, for hot ones - mirror, tinted, reflective.

From a practical point of view, windows with anti-condensation tempered, shockproof, self-cleaning double-glazed windows are often used, and in terms of decorative functions, stained-glass windows or colored glass are often used.

In addition, skylights can be equipped with remote control and other external and internal systems.

Velux windows

The famous company Velux is famous for its unsurpassed quality of products that will make your attic light and cozy.

Extensive experience in the global market allows the company to constantly improve products and achieve new quality standards.

Among the advantages of the roof windows of this company, one can distinguish them:

Facro publications

Fakro manufactures roof windows from high quality pine wood. During the production process, wood is treated with an antiseptic and varnished in 2 layers.

On the outside she's protected aluminum profile covered with polyester.

There are hinges in the middle of the window sash, which allows the window to be rotated 180° and easy to clean. A special latch fixes it in absolutely any position.

Thanks to ventilation grille, available on all Fakro roof windows, you can ventilate the room in the closed state.

The lattice has original design with good acoustic and filtration properties.

The handle on these windows is located at the bottom, which facilitates their opening without the use of additional tools. And its opening allows you to fix the structure in 3 positions: closed, ajar and open.

Fakro double-glazed windows are equipped with tempered impact-resistant glass.

The German company ROTO-FRANK invented Roto skylights, which are able to withstand the same load as the roof. Due to their special design and salary (for different types of roofing), the junction points will never leak.

These window designs have advantages that distinguish them from windows from other manufacturers:

• special fittings;
• built-in corners for mounting;
• complete set with a vapor barrier apron;
• finished thermal insulation block;
• adjustment of the sash after installation;
• the presence of a reliable seal around the perimeter of the sash and box.

Not so long ago, the company "ROTO-FRANK" began to produce roof windows of a new generation - Roto Designo. They have unique design, unique colors, modern finish, smooth shape of overlays, hidden fastenings.

In addition, the color palette of the overlays has expanded, and anthracite metallic has been added to the standard colors. All places where the window adjoins the roof are equipped with special seals, locks and other elements.

Which roof windows are better: Velux, Fakro or Roto

Composition comparison

Velux products are made from northern pine, a very dense and durable material. It is a glued beam coated with a fungicidal and varnish composition (in 2 layers).

Note!

Compared to other windows, these designs are considered stronger and more durable.

Facro products are made from high quality pine. It is made in the form of a glued structure impregnated with an antiseptic composition (under vacuum conditions) and coated with polyacrylic varnish in 2 layers.

Roto windows. For the manufacture of these roof windows, northern pine is used in the form of glued beams. Depending on the model, it can be two- or three-layer with fungicidal impregnation and varnish coating.

Double-glazed windows

Velux designs have energy-saving double-glazed windows produced according to modern technology"warm perimeter".

The weakest point of ordinary windows is the perimeter, so the dividing frame is not made of traditional aluminum, but of thin-walled solid steel with rounded corners.

Inside the double-glazed roof window contains an inert gas - argon, the loss of which is helped by silicone sealing (instead of butyl sealant). Velux double-glazed windows are able to withstand frosts down to -55 degrees.

Facro windows use energy-saving double-glazed windows filled with argon, as a result of which the attic space will be warm and cozy all year round.

The glasses themselves have increased strength, resistant to extreme weather conditions. Thanks to special fuses, the double-glazed window is protected from extrusion and breaking.

Roto skylights consist of a single-chamber double-glazed window, the glass of which has a thickness of 4 mm. Argon (krypton) is pumped inside it, which provides high thermal insulation.

The glass of some models goes through tempering to increase the strength characteristics.

Opening windows

Velux designs open very easily with a handle at the top of the frame. This makes it possible to place them on optimal height(up to 110 cm from the ceiling), which will provide good review even a sitting person, even standing.

Any interior items can be placed under the window, as the top handle will remain accessible.

Fakro roof windows can be fixed in six positions with the help of a handle and special latches. The handle is located at the bottom of the structure, which, of course, is convenient for short people, but dangerous for children and will not allow you to place anything under the window.

Roto products have a mechanism that allows them to rotate along two axes. Opening the window along the upper axis opens up an excellent view and at the same time will not let you get wet in rainy weather.

Using special fittings you can block the shutters at 4 points, which will protect against burglary.

Ventilation characteristics

All Velux models are equipped with a ventilation device, and some of them have a handle combined with a unique vent valve for ventilation.

These designs have a fairly high air exchange, which depends on the size. In addition, all of them are equipped with a removable filter that acts as protection against insects and dust.

Fakro and Roto skylights have similar ventilation valves, but in terms of device they are slightly inferior to Velux.

Mounting Features

The Velux company has provided for everything, so there is nothing complicated in the installation of their windows, because only ready-made, fitted accessories are used in the installation process.

Thanks to them, the probability of error is minimized and it perfectly protects against cold, leaks, and freezing. All Velux skylights are supplied with pre-installed brackets to facilitate the installation of curtains.

Fakro windows can be mounted both on the crate and on the rafters.

There is nothing complicated in their installation either, if it is carried out on the crate, because you do not need to adjust the step roof structures for the size of the window.

Roto structures are also mounted easily and simply on various roofs. They are attached to the crate, but you can additionally fix them on the rafters thanks to the installation corners.

tightness

Velux roof windows are equipped with a three-level contour seal, which perfectly protects against drafts and heat loss. Such a unique system allows them to be used in almost any region of the country.

Facro structures have a sealing contour around the perimeter, which ensures snug fit and prevents heat loss.

Roto products are also equipped with seals between the double-glazed window and the adjoining aluminum profile, which will eliminate condensation along the glazing contour.

Window accessories

Windows of all manufacturers can be equipped with various accessories, but Velux products have more decorative elements than the rest.

For example, they will decorate the house and make it cozy with a variety of curtains, roller shutters, awnings, blinds, mosquito nets, a remote control system (electric, solar-powered).

Thus, having considered the 3 main manufacturers of skylights, you can make the final choice, which will remain only for you!

Do-it-yourself installation of skylights

Installation of skylights should be carried out only according to the instructions and with a constant check of the quality of the installation. Otherwise the roof will leak.

In addition, many people make mistakes when self-assembly, which also leads to disastrous consequences. So read and remember.

How to install

To find out how to properly install a roof window, follow the recommendations below:

1. First of all, remember: the roof window is not attached to the crate, but to the truss system (vertical rafters).

2. If there are transverse horizontal beams in the design of the truss system, then it is better to place the lower part of the window on them. You can also focus on the slats of the crate.

3. The distance between the window frame and the rafters should not be less than 3 cm on each side. This distance is necessary to align the roof window.

4. To facilitate installation, you can install a horizontal beam under the bottom of the window to the truss system.

5. Installation of a roof window. Align the lower part of the window with a level and fasten the corners (not completely) with self-tapping screws (should be included).

6. We try to align the length of the window parallel to the rafters and tighten the screws in the oblong holes on the mounting brackets (also not completely, so that later you can fine-tune the position of the window frame).

7. When the roof window is already self-supporting, you need to align its position so that the distance between the frame and the rafters on the sides is approximately the same.

8. After the final adjustment and checking on all sides, the bolts can be tightened completely.

Helpful advice!

The waterproofing material must completely frame the window frame with an overlap on the sidewalls of the frame.

9. Laying waterproofing material. It should completely frame the window frame with an overlap on the sidewalls of the frame. The stacking order is from bottom to top.

First, the lower part of the material is fitted to the frame with an overlap, a cut is made in the side ledges to attach them to the roof. The side insulation sheets are then added with an overlap to the sidewalls of the frame.

The upper and lower protruding parts are cut from below and from above and are wound under the first lower insulating sheet, and from above onto the sidewall of the box.

The top sheet is laid in the same way as the bottom sheet, only this time over the sidewalls (cuts on the edges are made in such a way as to put them on the side sheets). As a result, all places of insulation overlays are screwed onto each other with self-tapping screws.

10. If you have a profile roof, then before installing the flashings under the roof window, you need to nail a thin rail in order to fix a soft corrugated apron on it, which will smoothly lie on the profile.

The rail is located at a distance of 10 cm from the lower edge of the window frame, and protrudes 30 cm on the sides.

11. Setting salaries. To begin with, remember: if your salaries are fixed with latches, clasps or latches, then additional mechanical fasteners(nails, screws) are not required.

Just as with insulation, the lower salary is first mounted (on top of the roof). A fixing pad for a roof window is put on top of it. The flashing and the overlay are fixed with the help of the supplied self-tapping screws into the prepared holes.

The side sections of the lower flashing are nailed to the frame with short nails (2 cm). The side flashings are inserted into the lower flashing until they stop (special cuts can be bent outward to strengthen the fastening).

Side salaries are also nailed to the window frame, and to the crate or rafters with clamps.

If you have a soft or flat roof, then the side edges of the salaries can be slightly crushed so as not to lift the roofing material.

Before the upper salary, you need to install lining on the roof window and screw it with self-tapping screws through special holes. The upper salary is installed simply: from the sides it is screwed to the window with self-tapping screws, it is attached to the crate with clamps.

12. If you have a soft or flat roof, then it can be laid from the sides on the salary only using bituminous materials. The profile roof is turned on its sides so that it ends with a whole upper arc.

And from above, the roof must be laid on a salary with an indent from it of 6-10 cm.

13. The junction of the flashings with the roofing material must be insulated with the sealant supplied with the kit, or with other adhesive tape.

14. After installing the attic box, a sash is put on it (or a double-glazed window if the window is deaf).

15. Window insulation can be carried out from the inside by slipping insulation around the perimeter (mineral wool) and closing it from the outside with a foil heat-insulating layer from condensate. From the sides of the slopes, the insulation also fits.

16. A vapor barrier is put on the insulation. As a rule, at its ends there are latches for fastening to a dormer-window.

In places where the vapor barrier apron leaves, additional fastenings can be made with self-tapping screws or sealant.

As a rule, rough slopes are installed in the attic window, which are subsequently closed by the general decoration of the room. It is not difficult to make such slopes: you just need to mark the length, width and angles for the top and side slopes.

Slopes for triangular attics are arranged in such a way that the lower slope looks vertically down, and the upper one horizontally. Attics with sloping roofs may not have strong slopes.

Note!

Do not forget that there should be heating under the attic window.

It should be taken into account that from different manufacturers installation methods for skylights may vary slightly. In the future, we will consider them separately.

Installation methods will also be considered. various kinds skylights and accessories.

Installation of skylights

Skylights are installed in roofs. Such windows in terms of design, as well as the principles of installation and operation, differ significantly from facade ones.

The main parameters affecting the operation of skylights:

• roofing pie device;
• correct installation;
• operation in the winter;
• microclimate.

Roofing pie device

In accordance with the instructions of most roofing manufacturers, insulated roofing cake should consist of the following layers (from top to bottom):

• roofing (metal tiles, flexible tiles, etc.)
• crate for roofing (solid or step; installation of skylights is carried out on this layer)
• ventilation gap (most often formed by a counter-lattice above the diffusion membrane)
• diffusion membrane (permitting steam from inside the room)
• wooden rafters, insulation
• vapor barrier
• rough binder

For details, see the manufacturer's instructions.

If roof windows are installed in the wrong roof pie (for example, there is no ventilation gap), there is a possibility of leaks in the window area associated with under-roof condensate.

Skylights Velux, Fakro, Roto

It is optimal that the installation of windows, whether they are Velux, Facro or Roto windows, is carried out by specialists who have experience in this type of work and who know the principles of the roofing pie.

When choosing a contractor, you should pay attention to the experience of the company, the number of employees, the existence of a contract, guarantees.

If you decide to install skylights on your own or involve installers without experience in this type of work, you need to read the instructions attached to the window and other branded products.

Installing windows requires the preparation of an opening. The width of the opening for mounting a roof window should be greater than the width of the window: for Velux - by 4 - 6 cm (preferably 6 cm), Fakro - by 2 - 5 cm (preferably 4 - 5 cm), Roto - by 6 - 7 cm (preferably 7 cm).

The height limit will depend on the shape of the slopes. For a slope of an “open” form (the lower slope is vertical, the upper one is horizontal), the location of the transverse boards is determined using a level.

For a slope perpendicular to the window, the distance between the transverse boards should be 4 - 6 cm greater than the height of the window (see installation instructions).

When installing a roof window, it is recommended to plan the slope of the "open" form, because. it provides better ventilation windows and better lighting.

Window frame installation. The window frame is installed using the brackets included in the kit on the crate / solid base on which the roofing is laid.

For correct installation roof window, the window frame must be aligned in a plane. If the slope is not even, wedges can be installed under the mounting brackets, usually included in the kit.

Also, the bevel of the window frame from rectangular shape. To do this, it is necessary to install the rotary part on it and align the window frame with it.

Insulation, waterproofing around the window frame. The window frame is usually located above the roof insulation layer, it is important to correctly insulate the “bridge” between the roof insulation and the window frame.

When installing a roof window, it is best to insulate this place with the material that is part of the installation package:

• Velux - heat-insulating belt made of foamed polyethylene
• Fakro - insulation blocks made of sheep wool
• Roto - built-in thermal insulation belt made of foamed polyethylene

When installing Velux or Facro roof windows, this area can be insulated with mineral wool, penofol and other materials ( mounting foam cannot be used), but it is more difficult and can lead to a reduction in the life of the window.

Waterproofing around the window frame is carried out according to the manufacturer's instructions.

Salary setting. It is carried out according to the manufacturer's instructions, it differs depending on the roofing. It is impossible to violate the integrity of the flashing strips (for example, drill with a self-tapping screw when fastening the metal tile around the flashing).

Insulation, vapor barrier slopes. After installing the roof window, it is important to lay the insulation on the slopes, if this is not done, the window may “freeze”. When mounting the frame under the slopes, the vapor barrier must not be damaged.

Helpful advice!

After installing the roof window, it is important to lay the insulation on the slopes.

When installing branded slopes, the frame is not required, because. the slope is held on the window frame in a special groove.

Remember: professional installation windows are cheaper than reinstalling an incorrectly installed one (especially in cases where any elements of the window / flashing / roof have been damaged).

Availability attic floor in a private house or cottage allows you to rationally distribute living space. Instead of a dusty attic space that was used as a pantry at best, modern homeowners are equipping comfortable bedrooms, children's rooms, libraries and studies, kitchens and dressing rooms. The presence of an attic not only expands your possibilities, but also increases the aesthetic appeal of the house.

But, like any room, a bedroom or a nursery in the attic needs windows.

However, when arranging such a structural element of a building, it is necessary to take care of sufficient natural light. With a vast area of ​​the room, the light transmission capacity of the windows in the gables of the house does not always meet the desired requirements. The installation of roof windows will help to solve this issue. Thoughtful placement of the window opening and the correct calculation of the glazing area will allow you to distribute flows sunlight so that in daytime there was no need for additional lighting.

To avoid unpleasant surprises in the form of leaks and drafts resulting from a violation of the tightness of the roof, it is recommended to entrust the installation of windows in the attic to only qualified specialists.

Types of skylights

On the domestic market of building products, there are two types of windows for arranging the attic floor:

Among the most uncomplicated models - simple vertical structures, which have much in common with standard front-glazed windows. In addition to the pediment of the attic floor, they are mounted in the roof slope on remote structures. The main advantage of this solution is an impressive aesthetic component, however, the quality of lighting may not meet expectations due to the limited light flow.

A small window gives little light, and the room will require additional lighting.

Inclined models– an effective approach to solving the problem of natural lighting in attic. Such windows let in 40% more daylight and are installed at the same level as the roof slope.

Inclined windows can be of different sizes, but they let more light into the rooms than straight windows of the same area.

In the manufacture of the frame of the roof window, various types of wood, aluminum or composite are used. If the attic is equipped for a bedroom, living room, dressing room, library or other room with a low level of air humidity, eco-friendly wood is preferred. In the kitchen, bathroom or jacuzzi, install plastic structures, because they are resistant to the destructive effects of microorganisms, moisture and aggressive compounds.

Standard roof windows, which are mounted in a rectangular or square opening, are in the greatest demand due to their ease of operation and installation. balcony windows for the attic, they are made in the form of structures made of inclined glazing in the roof slope, connected to a vertical window structure under it. Installation of such models requires a high level of professionalism and knowledge of the nuances of installation. Cornice windows are designed for an attic room with a high wall, which complicates access to inclined structures. According to the method of opening, window structures for the attic are distinguished with a central, lateral or combined axis of rotation of the sash.

The roof window can go along the wall and go to the roof, and each of the two halves of the window opens separately

Each of the varieties has a number of advantages, so when choosing, you need to focus on the features of the layout of the room, the purpose of the structure and personal preferences. In attics with a high roof, where there is no access to the window opening, models with a remote control are often used. Installation of such a window requires a separate power line to the installation site.

On our website you can find contacts of construction companies that offer window and door installation services. You can directly communicate with representatives by visiting the exhibition of houses "Low-Rise Country".

Key installation steps

When performing installation work, do not forget that the windows cut into the inclined elements of the roof take on the load of protecting the building from climatic phenomena and other factors. external environment. Therefore, when choosing a suitable double-glazed window, increased requirements are placed on the quality of materials.

The plastic components must be UV resistant and the glass must have anti-shock characteristics. Also, the reliability of the window structure is largely determined by the presence of external protective linings made of durable composite and high quality rubber seals. Rolling systems or blinds built into the interior will successfully replace traditional curtains or drapes.

Roller shutters or blinds will help hide from bright sun or from the full moon

In addition, when choosing a window for the attic, the following characteristics are taken into account:

dimensions constructions;

way opening;

mounting technology depending on the roofing;

Availability additional devices for ensuring air circulation (removable mosquito net, supply channel).

After choosing a window structure, an installation is performed, consisting of a series of operations that are performed in a certain sequence:

Preparation openings in the roof;

installation work on fastening frames;

security hydro- and thermal insulation;

fixation drainage tray and window frame;

installation double glazing;

finishing work around the window.

Determining the required glazing area

The size of the window opening, which will provide sufficient attic lighting, depends on the area of ​​\u200b\u200bthe room. For every 10 m² there should be 1 m² of glazing. In this case, it should be borne in mind that the light flux depends not only on the dimensions of the window, but also on its placement. The higher the glazed structure is located, the greater its light transmission.

However, high placement is only suitable for roofs with a gentle slope at an angle of no more than 20º. In addition, such an installation is not suitable if you plan to admire the beauty of the surrounding landscape. When arranging a window opening in a roof with steep slopes, the distance to the floor should vary between 1 m and 1.4 m.

Frame assembly

Before proceeding with the installation of the window frame in a pre-prepared opening, it is necessary to remove the double-glazed window.

Dismantling features depend on design features a specific model, therefore, when performing work, the masters are guided by the manufacturer's instructions, which describe the process in detail.

For the installation of windows, a section of the roof is being prepared where they will be located

After dismantling the double-glazed window, the frame is installed:

Top part is fixed without tightening the screws, while the lower one is mounted on the brackets.

With water or laser level flattens out structure position.

Having previously fixed the brackets, they are inserted into the window frame movable element and check the functionality of the locks. With the correct arrangement of the structure, the double-glazed window fits snugly to the rubber seals along the length and width, the shutter mechanism works properly without application special efforts. If everything suits and no modification is required, the double-glazed window is removed from the frame and the installation work continues. If difficulties arise, additional adjustments are made.

After careful alignment of the frame around the entire perimeter of the structure insulation is attached and waterproofing material.

Insulation is an important part of installing windows so that it is not cold in the room during the cold season.

Arrangement of the drainage system

When installing skylights, care must be taken to install a drainage gutter, since its presence to a large extent determines the protection of the room from precipitation. This structural element is fixed on the base of the roof under tiles or other roofing material (ondulin, corrugated board, slate, etc.).

In most cases, factory-made metal gutters are used, giving preference to proven brands. The angle of inclination of the drainage system should be about 3-5 degrees relative to the window structure, so that when draining rainwater didn't hit the glass.

Installation of window flashing

An important step in the installation of roof windows is the fastening of the insulating salary from the outside of the opening. The correct installation of this component determines the tightness of the structure and protection from atmospheric phenomena. Installation work begins with fixing the lower corrugated apron and side parts and ends with the installation of the upper ceiling and fixing the plastic lining.

It is important to note that the installation of the salary is carried out only when the roof is already covered with roofing material - tiles, slate, corrugated board, etc.

Installing a window flashing will prevent water from leaking

Fixing a double-glazed window

At this stage, the technology for installing roof windows is determined by structural models and technical characteristics of a particular model. When performing installation work, contact detailed guide from the manufacturer, since each brand has its own assembly nuances.

In addition to fixing the double-glazed window into the frame, the instructions from the manufacturer contain recommendations on the use of shutter mechanisms and adjusting the position of the structure. The use of special fasteners allows you to tightly press the glass to the frame, eliminating the possibility of cracks.

Finishing work at the final stage

When window construction installed and the main installation work is completed, it is necessary to make slopes. The basic rule to follow at this stage is to place the top slope in the vertical plane and the bottom slope in the horizontal plane. With such an installation, the side planes of these structural elements have the shape of a triangle or trapezoid.

Slopes will give completeness to the window space

This arrangement promotes the natural circulation of air currents that prevent the formation of condensation products on glass surfaces. The main material for the manufacture of slopes is drywall or lining. Some Models plastic windows equipped with factory slopes made of hard plastic, which are easy to install and require minimal maintenance.

The nuances of installing windows in a soft roof

When arranging soft roof a synthetic coating is used, which is distinguished not only by impressive water-resistant characteristics, but also by ease of processing. To equip a window opening, a well-sharpened knife and saw are sufficient, and when mounting the support rails, a screwdriver and self-tapping screws are used. Despite the apparent simplicity, you should not make independent attempts to perform installation work, since the slightest oversight will lead to undesirable consequences in the form of depressurization of the roof, violation of the microclimate in the room, etc.

Accuracy and professionalism during installation will allow you to get an excellent result.

High-quality and accurate work performed by qualified installers will eliminate the need re-installation. Since there is always a solid base under the soft roofing, extreme precision is required when cutting a hole. The dimensions of technological gaps should not exceed 3-5 cm. If there is a need for support rails, the structure is supplemented with auxiliary components made of wood.

Technology for installing windows in a metal roof

The structural elements of a roof covered with metal tiles or corrugated board have much in common with the arrangement of a soft roof, so specialists do not have questions about how to install a roof window, even with complex layout features. Mounting process window openings performed in the same way. The only difference is that instead of using a saw blade to cut the outer covering, it is electric jigsaw or metal shears. The nuances of installing individual models are prescribed in the manufacturer's recommendations.

Installation of windows on a roof covered with metal tiles also has its own characteristics.

It should be noted that at installation work for the arrangement of roof windows, efficiency and clear phased implementation are important. If the installation of a structure is delayed for days or even weeks, sudden rain or other precipitation can cause serious damage.

Conclusion

If you want to install skylights, you must remember that for their competent installation you need to know a lot of nuances that are known only to professionals with extensive experience. In addition, many manufacturers give a guarantee for their products only if the installation of windows was carried out by installers who have undergone special training. Therefore, in addition to buying a window, you must immediately decide who to entrust the installation to, so that the result of the work will please you for as long as possible.
