Installation of Velux skylights. Do-it-yourself velux roof window installation

  • 20.06.2020

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 a chic house and is now 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, visibility and illumination of the room, as well as building codes, 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 window: 0-4cm 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, the optimal distance between the rafters is 57-60 cm).

Useful 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 correct 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. Installation of a window in a roof with a continuous crate is carried out similarly to the installation of a window on 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, the price of which is available to everyone from the best manufacturers, Wholesale and Retail.

If you are going to buy attic plastic windows, our company will offer the 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 of load-bearing elements in terms of reliability, strength, and water tightness.

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, roof windows can be equipped with remote control and other external and internal systems.

Velux windows

The famous company Velux is famous for unsurpassed quality 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.

Outside, it is protected by an 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 the ventilation grille, available on all Facro roof windows, it is possible to ventilate the room in the closed state.

The grille has an 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 means. 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 (under different types roofs) 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 antiseptic composition(under vacuum conditions) and covered 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 structures 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 skylights 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 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.

Skylights from Fakro and Roto firms have similar ventilation valves, but in terms of the device they are slightly inferior to the Velux company.

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 there is no need to adjust the pitch of the truss structures to 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 designs have a sealing contour around the perimeter, which ensures a 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, remote control(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 in design truss system there are transverse horizontal beams, 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.

Useful 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, clamps or latches, then additional mechanical fasteners (nails, self-tapping 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 departs, you can make additional mounts 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. Attic with broken roof may not have strong slopes.

Note!

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

It should be borne in mind that the methods of installing roof windows may differ slightly from different manufacturers. 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, an insulated roofing cake should consist of the following layers (from top to bottom):

  • roofing (metal tiles, flexible tile 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 the 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 more height windows (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 batten / solid base on which the roofing is laid.

For the correct installation of the roof window, the window frame must be aligned in the 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.

Useful 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.

This article is for informational purposes only and is not intended to be a guide to installing skylights.

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).

Hide

Velux skylights are delivered to the consumer along with a salary, thermal and waterproofing, and slopes. Together with these assembly units, an instruction is also provided, which explains in detail how to install the Velux roof window. It is imperative to follow the instructions in order to ensure a durable and trouble-free operation of the window. The purpose of this article is to explain the main provisions of this instruction.

Installation of Velux skylights

For correct installation roof window, the opening in the roof should be larger than the window dimensions by 45-50 mm in height and 30-40 mm in width.

Installation work

If you install a window from inside the attic, then you need to remove the sash with a double-glazed window from the window frame. If you are installing from the roof, then this is not necessary.

The window comes with special fixing plates, often also referred to as "cleats". They turn over the corners of the window box and screw it with screws. With their horizontal shelves, the plates lie on the rafters and are screwed with screws.

Mounting plates are clearly visible

With large window dimensions (1400 mm or more), it is also equipped with central brackets for fixing to transverse bars installed at the lower and upper edges of the window frame.

The gaps between the window and the details of the roof should be filled with putty only on a bitumen basis: on silicone - it is impossible.

Velux roof window flashing - used to connect the window to the roof. It is an aluminum frame, the outer profile of which consists of a system of grooves for water drainage.

There are two types:

  • EDW 1000 - for profiled roofs,
    EDS 0000 - for smooth roofs.

Thermal and waterproofing of the roof window "Velux"

Velux roof window waterproofing installation

The Velux roof window is thermally and waterproofed using the BDX 2000 accessory package. It includes:

heat-insulating sealant made of foamed polyethylene. Covers the window around the perimeter and eliminates "cold bridges".

waterproofing apron. Frames the window and connects to the roof waterproofing. It is made of folded material and therefore tightly adjoins any type of crate.

The kit also includes a drainage chute, which is designed to collect and drain condensate that appears in the under-roof space above the window. After its installation, the waterproofing apron is placed so that the water from the drainage gutter is collected in the apron and flows from the under-roof space outward, down the roof.

The installation of the salary starts from the bottom bar and then leads from the bottom to the top. It serves to protect and fix the waterproofing apron and seal. After installing the salary, you can put the window sash in place (if it was removed).

Installation of slopes to the roof window Velux

Preparation for installation of slopes

The third set of assembly units is slopes.

These are strips designed to frame windows from the inside - the formation of an expanding socket from the window into the room.

The slopes LSC with a depth of 40 cm and LSD with a depth of 50 cm are used. In addition, there are slopes of the LLC, LVI series for some special types of windows - eaves, etc.

Slopes LSC and LSD are supplied with a template and miter box.

This is how the slopes are installed

The template allows, without resorting to measurements, to determine the angle of the roof and select correct location upper and lower slopes. It is believed that for better circulation of warm air, the upper slope should run parallel to the floor, the lower slope should be perpendicular.

The miter box helps to cut the slopes at the right angle without measuring and marking.

In addition, the kit includes BBX 0000 vapor barrier film, adhesive tape and butyl sealant.

After the nest is insulated under the slopes, the film is applied to the insulation and glued to the window with a sealant.

Installation of slopes in the assembly

Adhesive tape is used to connect the film with the vapor barrier of the roof.

All four slopes are assembled as a separate assembly unit, “snapped” onto the locks and inserted into the socket until they close with the window frame. The gap between the slopes and the wall is closed with platbands.

The simplest version of the installation of Velux roof windows is schematically described above. There are also more complex options. For example, the combined installation of several skylights at once: in a row or one above the other. Also - the installation of Velux skylights on roofs with a curvilinear shape and similar cases.

The cost of installing Velux skylights

Salary water flow scheme


In a private house, the attic is another room. To turn the attic into a full-fledged residential, it is necessary to install windows. It is better to do this immediately at the stage of roof construction.

Roof window installation soft roof more difficult: for installation, you will have to cut a large section of the coating, lining plywood, roofing cake and even rafters if they are installed with a small step.

The technology for installing a roof window in a soft roof depends primarily on the design of the windows themselves. Manufacturers have different installation requirements. For example, Velux models can only be attached to rafter legs, while FAKRO and ROTO are often attached to the batten.

Consider general rules installation.

Scheme and choice of model for installing a roof window in a soft roof

When choosing a model and determining the required number of windows, they proceed from the calculation of 1 square meter of a translucent structure per ten squares of the attic area. It is recommended to draw up a window layout in advance.

  • for steep roofs, the window is set so that its lower cut is located at a height of from one meter to 1.4;

  • if the slope is within twenty degrees, you can place the window higher - the illumination will be better;

  • the minimum installation height is 80 centimeters, the maximum is ninety meters.

The height is also affected by the design of the block itself. More precisely, the location of the handle:

  • if the handle is on top, the window is placed no more than 1.1 m from the floor;
  • if in the middle - 1.2-1.4 meters;
  • at the lower position of the handle, if there are children in the house, you can not put the window low. Not less than 1.3 meters.

The window is installed between the rafter legs. The width of the model is selected so that about two centimeters remain between the frame and the rafters on both sides. A heater will be located along the perimeter of the frame, the width of the gaps between the box and the rafters depends on its thickness.

Our work

Mounting order

1. If the roof is already ready, you need to cut an opening for the window box in it. The opening is made along the cut of the rafters: the same gap is left between the edge and the box as between the box and the rafters. This is how all materials are cut with the exception of the waterproofing layer: you need to leave an extra 20-25 centimeters of overlapping film.

2. If the ceiling is lined with drywall or clapboard from the inside, it will be difficult to determine the location of the opening. It is recommended to have a rafter layout on hand, otherwise you will have to dismantle some of the panels. Before cutting the entire opening in drywall along the contour, several through holes to relieve stress.

3. Above and below the opening, transverse bars are nailed to the rafter legs. Their installation is mandatory if it was necessary to remove a section of the rafter to install the window. If not, it is still recommended to nail the bars: this way the window will hold on tighter.

4. A drain pipe / gutter is placed on top of the finished opening under a slight slope to drain condensate, and attached to the crate. The length of the gutter is equal to the width of the opening. The slope is necessary so that the water does not stagnate, but spontaneously flows into the roof ventilation gap.

5. Remove the sash from the window. If the window is deaf, take out the double-glazed window.

6. Attach the box to the rafters and cross bars with corner brackets. One shelf is screwed with self-tapping screws to wooden element, the second - to the window frame. The bottom edge is fastened tightly, on the top the screws are not fully tightened.

7. Adjust the design according to the level. Serious distortions are corrected with plastic corners. It is recommended to put the sash back in place to make sure it fits correctly. After adjustment, the sash is removed again and the fasteners are tightened.

8. Lay waterproofing and insulation around the window. The edges of the waterproofing apron are led on one side under the waterproofing layer of the roof itself, on the other - under the condensate gutter. The edges of the roof waterproofing are fixed to the frame. Fastening - galvanized nails.

9. Close the mounting seams with flashing strips from the window kit. First put the bottom part, then the rest. All strips must be brought under an elastic seal.

10. From the inside, the gaps along the perimeter of the frame are sealed with heat-insulating or sealing material, vapor barrier is laid and the slopes are processed. The bottom slope should be horizontal, the top - vertical.

11. Return the sash to its place.

You can slightly change the installation sequence: first sheathe the opening heat-insulating material and then install the frame. Strips of insulation are attached to the rafters and bars with a stapler.

Installing skylights on a soft roof is an energy-intensive business and requires high precision.

Poor installation of an inclined roof window will lead to the fact that the attic will be constantly flooded with rain, under roofing condensation, rain and snow moisture will begin to accumulate. All this will accelerate the wear of the roof and the whole house.

/ / Installation of Velux windows

Installation of Velux skylights is a matter that should be approached with all responsibility. Windows can be installed both in the roof under construction and in the finished roof. But either a certified professional or a person who has high skills in high-quality performance of any kind can do it right. construction works. If you entrust the installation of Velux windows to an amateur, then expose yourself to a great risk of getting a poor-quality installation. As a result, you will face the need for subsequent reinstallation, which will not allow you to achieve the same quality of installation as during the initial installation of windows. Therefore, we recommend that you familiarize yourself with some rules and features so that you can monitor the work of the installer and control all his actions.

Before starting work, you must carefully read the installation instructions for Velux roof windows, which is attached to each product. Next, you should choose a suitable place where the window will be located. At this stage, careful measurements should be made and the contours of the future window opening should be noted. Be sure to keep in mind that in terms of dimensions, the opening should be 60 mm wider than the window and 45-50 mm higher than it. It is advisable to install transverse beams in the plane of the rafters at a distance of about 20 cm from the window, so that in the future it would be possible to make the upper and lower window slopes"open" form. The installation of Velux windows depends on one more thing. important factor is the slope of the roof. The smaller it is, the higher the window should be. In addition, if the sash handle is on top, then the window should be installed at a distance of 80 cm from the floor, and if it is below - at least 110 cm. All these calculations will help you achieve greater safety and convenience when washing windows, as well as provide excellent visibility both in standing and sitting positions. Now you can remove the casing and cut a hole in the insulation and waterproofing material according to the markings. The material should not be completely removed, it can be wrapped inside the attic to use it when insulating windows.

In order to produce correct installation windows, you should first remove the sash from the frame (if Velux windows are installed from the inside of the room), and then fix the box on the crate or rafters using the brackets included in the kit. Pay attention to the bottom edge, it should not interfere with the future installation of slopes. Do not fasten the top brackets until final alignment. Always make sure that the bottom of the box and the swing frame are parallel to each other. At the end of this step, level the structure again and secure the top brackets.

To provide reliable protection from the cold, you should lay a belt made of foamed polyethylene on steel frame. If you have not purchased a branded installation kit for installing Velux skylights, you can perform thermal insulation using mineral or basalt wool, as well as foam foam. If desired, nail it on top with staples, but usually the thermal insulation rests on the insulation laid below, which, in turn, is located on the vapor barrier. Also included in a special kit is a waterproof apron that prevents the penetration of moisture. It must be fixed around the perimeter of the frame, turning the edges under the crate. The top edge of the insulating apron must be brought under the drainage gutter. To install it, cut openings in the counter-lattice above the window, and cut the waterproofing film in the middle. Install the drainage gutter in the gap between the counter-lattice and insert it into the cut under the film. So under-roof condensate will not drain onto your window.

You should proceed to this stage of work only when you have completed the installation of the window frame and laid the hydro and thermal insulation. The salary is a frame gutters and overlays. It performs several functions: fixes the insulating apron and seal, provides high protection against atmospheric precipitation, and also gives completeness window construction. The installation of the salary is carried out using special clamps in a certain order: the lower bar, then the side sections, and finally the upper part. Upon completion of all stages of work, you can insert the sash back into the frame box. This can be done using the lock button, which is located on the swivel hinge.

The final stage, which includes the installation of Velux roof windows, is the finishing of the side surfaces of the window openings. Slopes not only help to give an aesthetic appearance to the window system, but also significantly affect the level of illumination of the room. In addition, if the lower slope is placed vertically and the upper slope is horizontal, then you will achieve excellent air circulation. The assembled slopes are attached to the locks. In order to avoid wetting of the insulation, it is necessary to seal the joints of the slope vapor barrier with the window frame and roof vapor barrier with high quality. The gaps between the slopes and the wall should be closed with platbands.

If all the installation work was carried out professionally and efficiently, then you can be sure of the reliability of the windows and their long-term service.
