Work order for the installation of a complex of four paired ones. Leaving the proprietary insulation technology BDX 2000 in favor of an alternative inexpensive insulation technology using our own development and penoizol material 8)

Preparing the opening. An opening was cut and prepared in the thickness of the insulated roof, the distance between the rafters was 800mm. Rafter board 200mm. Steam and waterproofing were also cut out. The vapor barrier was not completely cut off, but wrapped around the edges. In the future, it will be useful for insulating devices.

Attaching the Main Mounting Brackets to the Velux window frame. The brackets are fastened with self-tapping screws, focusing on the red line, which conventionally indicates the upper edge of the sheathing.


Penoizol was cut into strips. Double-sided special connecting tape was glued along the window frame.



At this stage, the frame cannot be secured separately from the others, you can only attach it. Thorough fastening occurs after the entire complex of 4 Veluxes is installed and leveled.


In order to install the entire set of windows evenly, the manufacturer provides mounting sockets on the brackets.

You can also use a cord 8)

In the cavity between the window and penoizol they additionally laid basalt insulation. We sealed everything and carefully stitched it with a stapler.

The insulation is ready, now our window will not freeze in the winter!



One of the final stages of installing a roof window is installing a drainage flashing. Installation of side and middle paired parts


It's evening and work is coming to an end.



Finally, all the frames are installed and double-glazed windows are inserted into them. All that remains is to fold the penofol and put a vapor barrier on top, which must be glued with tape or double-sided connecting tape.

The complex of skylights is ready. It is worth recognizing that a room with such a complex will look great.

VELUX, the world leader in the production of roof windows, regularly conducts training for managers selling their products, talks about their developments, the basics of sales, shows in practice the features of installation and the advantages of completing windows with original components and accessories.

At the same time, VELUX windows are always made of laminated wood, the material is Karelian pine and polyurethane, and as a result:

1. environmentally friendly, do not emit phenol;

2. do not lose their appearance (do not turn yellow);

3. wear-resistant.

VELUX windows will bring comfort and light to your home!

Do-it-yourself installation of Velux roof windows

The installation of the tiles was completed three weeks ago. Unfortunately, I was a little confused ]]> with the windows. It turned out that the windows I ordered are no longer produced. Velux has started production of a new series of windows. The supplier told me that the new windows would be lighter by reducing the frame size and increasing the glass size. For this pleasure I had to pay an additional 90 euros for all three windows. Dormer windows It was delivered last week, but my roofer is stitching it up Lately due to the large number of orders, so the windows had to stand for a week. The roof windows will be located in non-residential rooms, so I decided to order the cheapest roof windows. I ordered three roof windows with top opening along the central axis (two windows 134 x 140 cm, one window 94 x 140 cm). The choice fell on plastic skylights.

]]>

I did not order Velux branded material for heat and vapor barrier under the slopes of the roof windows. The roofer brought his vapor barrier film for roof windows. In addition, it was already included in the price of installing roof windows.
]]> ]]>

Installation of the skylights took almost the whole day. In the afternoon, the rays of the setting sun filtered into our eldest daughter's bathroom. Now we are thinking about what curtains to choose for the roof windows. Velux offers dimming and roller blinds. In any boiler room you will need to buy a blackout curtain so that the heating boiler does not heat up. But on landing And in the bathroom you can install roller blinds to softly diffuse daylight.
]]> ]]>

I chose aluminum frames for the skylights. We covered the roof cement-sand tiles Nelskamp S-Pfanne Longlife is in anthracite color, so the frames for the roof windows were also ordered in a dark color.

Installation instructions for Velux roof windows

]]> ]]>

The lower edge of the window must be positioned in relation to the cross beams (if any) and the sheathing batten in such a way as to produce internal lining under the window vertically, and outside - horizontally.
]]> ]]>

The window opening in the roof should be 50mm larger than the window frame in height and 30-40mm in width (approximately). The recommended distance between the roofing ]]> material and the window frame should be strictly observed. The distance between the rafters and the window frame should not exceed 30mm on each side. To make installation more convenient, you can install a temporary support beam under the window. Using a level, level the lower part of the window horizontally, then secure both lower corners with screws. Then each upper corner is secured with a screw in the middle of the oblong hole. You should not tighten the screw all the way; you should leave room for adjustment.
]]>

To prevent drafts and moisture from entering the room, you must strictly follow the instructions. It is necessary to adjust the gap between the box and the frame. It should be the same along the entire length of the sides. These actions must be performed immediately, since it will be impossible to make adjustments later.

]]> ]]>

Perform the second adjustment.

It is necessary that the frame covers its entire width evenly. To do this, the gap between the window frame and the lower parts of the frame must be the same. To level the gap, place the included plastic wedge on the side where the gap was selected first, under the upper corner.
]]> ]]>

The insulating roofing material (glassine) should completely go around the perimeter of the window frame, reaching its top edge. When fixed to the corners of the window frame, the insulating roofing material should be slightly raised at the cut points. Cloths adjacent to the window insulating material to ensure sufficient wind insulation and waterproofing, they must overlap each other by 200 mm or more. If the roof structure does not provide waterproofing, then its installation around the window is mandatory.

]]> ]]>

]]> ]]>

]]> ]]>

In the cardboard packaging of the flashing you will find a description of its installation and all the necessary details. You should not use the description in the package; it is much better to install the flashing by following these instructions.

Above are instructions for installing a roof window. Maintain the distance between the roofing material and the window frame. If the roof structure includes sheathing, it is necessary to install a drainage gutter.

7. Install the lower part of the flashing (1), then the lower window trim (2). Secure them using the supplied screws, screwing them into the pre-prepared holes. Secure the lower side sections of the flashing (3) to the frame using nails.

]]> ]]>

8. Insert the side sections of the flashing (2) until they stop into the lower section of the flashing. Bend the notched part (1) for greater stability. Attach the side sections to window box nails, to the sheathing (3) - using clamps. To provide correct location roofing material, sometimes it is necessary to slightly press the edge of the side sections of the flashing (4).

]]> ]]>

9. Using the supplied screws, secure the side (1) and top (2) pads in the prepared holes. The roofing material must be brought close to the fold on the flashing (3). To fix the roofing material when laying it on the flashing, it is allowed to use only bitumen-based materials. The use of silicone-based materials is not permitted.
]]> ]]>

10. Install the upper section of the flashing, secure it with clamps on the sheathing and screws on the window frame.

If necessary, the roofing material above the window can be cut at a distance of 60-100mm from the top edge of the window frame.

If you removed the frame, reinstall it. There is a locking button on the rotating hinge of the frame, which automatically snaps into its original position when closing the window.

Attention!

Each window or frame purchased comes with detailed instructions for its installation. Here are general (schematic) instructions.

Attic rooms allow the most efficient use of living space, which is why more and more often houses are equipped with rooms in the attic. Like any other living space, the attic needs a sufficient flow of light, which cannot be provided by electric lighting alone. Therefore, they are equipped with windows that have a certain specificity in design, due to distinctive features the structure of the attic itself.

Most popular manufacturers windows for attic spaces are Velux, Roto and Fakro roof windows. The sizes and design of windows are selected individually, based on the layout and needs of the attic. Windows are available in various modifications; according to the type of installation, they are divided into:

  1. Vertical windows are the simplest modification, which are practically no different from windows in other rooms. They are mounted in the front part of the attic, where the wall is located at a right angle or in a slope. Installation of Fakro or Velux roof windows in a slope at right angles is carried out using a small extension additional design in the form of a birdhouse-like house. Such windows allow you to slightly increase the area of ​​the room, but at the same time let in a small amount of light.
  2. Sloping windows. Mounted at the same angle with the roof slope. This design lets in more light and has a variety of opening methods. Not only the classic opening of the sash horizontally and vertically, but also the turning of the sash by 180° and much more.

The following classification divides Fakro and Velux roof windows according to features in their design, which also affect the installation process:

  1. Windows have a standard shape - square or rectangle. They are the most common; in their design they have a frame and a blind or opening sash. The most popular are designs with an opening sash; Velux or Fakro roof windows without the function of opening the sash must be ordered separately.
  2. Windows transforming into a balcony. This design consists of an inclined frame installed in the slope, the second frame is installed on the side or below. One door opens up, and the second opens to the side or down, forming a small loggia.
  3. An additional element at the bottom of the window. The opening sash is equipped with a small blind element at the bottom. This addition is used when the size of the slope is not large enough to install two openings, and the lighting from one window is not enough for the entire attic.
  4. Extensions at the top of the frame. They are made round or triangular. This extension decorates the window and makes it look like a medieval battlement.
  5. Cornice window. It is installed in rooms with a high wall, in which the view through the inclined frame is limited. The inclined design is complemented by an opening vertical sash.
  6. Light tunnel. This design does not occur very often and is very specific. Installed in places where the slope does not have direct contact with the room. The design is a window through which there is a tunnel or pipe with a hole in the place that needs to be illuminated. A light-diffusing lamp is installed at the end of the tunnel.

Dormer windows take on a much greater impact than ordinary openings in walls. They are made from special materials that are suitable for use in these conditions. The installation of roof windows also has its differences. The price of these products also differs from the cost of conventional double-glazed windows, this is due to their increased strength and design features. For example, a design with a rotating sash has a higher price than a window with a regular sash movement mode. Based on the capabilities of sash movement, windows are divided into:

  1. With a centrally located pivot axis that rotates 180°.
  2. With a rising pivot that opens 2/3 from the bottom edge of the frame.
  3. With a combined opening axis that allows you to turn or lift the sash.
  4. With a side-mounted axle that functions as standard.
  5. With a bottom-mounted axle that moves forward.
  6. Remote controlled windows. Necessary if they are located in an area that is difficult to reach.

Structural elements of roof windows

Dormer window systems are a complex structure that can withstand significant loads. This structure consists of a frame, sash and fittings that rotate the sash and fix it. The price for Fakro company products and Velux roof windows is determined by these factors, as well as the presence of additional installation elements.

Installation of Velux and Fakro roof windows is carried out with the addition of an apron for protection against moisture and steam, a gutter for water drainage, temperature-resistant material, a protective flashing and internal slopes. These elements complement the installation kit at the request of the ordering person. In general, the installation price for Velux windows and Fakro roof windows varies, depending on the number of main and additional elements. Self-installation of windows significantly reduces the cost of all work.

Installation diagram of dormer windows, selection of installation location

Do-it-yourself installation of roof windows begins with choosing the installation location. It is selected according to the following rules:

  1. The window sizes are selected based on the size of the attic and the gap between the rafters. When making an opening, it is not recommended to violate the integrity of the rafters; an opening is made between them.
  2. The optimal window area is 10% of the total area of ​​the room. Side edges frames are mounted at a distance of 4-6 cm from the rafters. If the gap between the beams does not allow installing a window of sufficient size, an additional opening is made.
  3. The installation height is selected according to the slope of the roof. At large angles, openings are made at the bottom, at flat ones at the top. The position of the handle is also taken into account; if it is attached at the top, the window is installed at a height of 100-110 cm, the lower position of the handle involves installing the window at a height of 120-130 cm.
  4. There is a dependence of window installation on the roof covering material, in ceramic tiles no cuts are made, the window is located above the row of covering. IN sheet material openings are cut at any convenient height.
  5. Methods of movement of the sash are selected based on personal preferences and desires.

After determining the installation location and dimensions of the structure, the selected areas are marked on interior wall. To install roof windows from Fakro, Velux or another manufacturer, it is recommended to select all components from one model line.

Preparing a site for installing roof windows

Let's consider installing Fakro or Velux roof windows on an already built roof in a room with unfinished walls. In this situation, a waterproofing film has already been placed on the inner surface of the wall, and the area for installation is marked on it. The gap left from the frame to the rafters is 2-3 cm, installation is carried out on the lower mounting beam. When marking the bottom line, leave 9 cm for roofing materials from the profile, for flat ones leave 4-6 cm. Along the top line of the window leave 9-15 cm up. Then proceed like this:

  1. According to the marks, a cut is made in waterproofing layer, retreating 20 cm on each side. The remaining areas are wrapped inside the room, and the roofing material is removed.
  2. Stepping back 2 cm from the rafters, cut off the lattice.
  3. The mounting beam is fixed along the bottom line; it is selected from 50 mm in thickness. The timber is fixed at a distance of 8-10 cm from the sheathing. Check the horizontal position of the timber using a building level.
  4. Attached to the beam with a stapler bottom edge waterproofing material. The upper edges are attached to the top sheathing, the side edges extend outward.

Installation and adjustment of a roof window

When installing the frame, you must follow the installation instructions for skylights from the manufacturer whose products were purchased. Windows of different brands have design differences. Some companies make rectangular brackets that attach to the rafters, while others offer products with angle brackets that attach to the rafters and sheathing. In all brands, the frame is fastened to the window in different positions. For example, for Fakro roof windows, the instructions describe two grooves marked V and N, which determine the seating depth of the frame. This indicator varies with different types of roofing and flashings. In general, the installation looks like this:

  1. The sash is removed before installation; this process is described in detail in the instructions for the window. The salary is also removed, at initial stage Only one frame is mounted.
  2. The brackets are mounted in the designated places on the frame. Thermal insulation is attached to the top of the window and secured with a stapler.
  3. Heat-insulating material is laid on the mounting beam, pressed down with a frame and fixed.
  4. The brackets in the lower part are fixed firmly, but the upper ones are not completely fixed, since the frame still needs to be leveled. Mount the sash and check the smoothness of its movement. If there are distortions, adjust the level using the upper mount. A fully fixed window must be level; the gaps on the sash should not vary. If you do not adjust the window at this stage, then it will no longer be possible to correct the misalignment.
  5. The installation of roof windows is completed at this stage by tightening all fasteners until they stop. Side fastening systems are also installed to the rafters. Side insulation is attached to the window, and insulation is laid on the sides.

Installation of waterproofing around the frame of a roof window

A waterproofing apron is included with almost all brands of windows, this applies to Farko designs and Velux roof windows. Installation of waterproofing material begins after installation of the window base. If this material was not included in the kit, then it is purchased and manufactured independently. The cost of installing roof windows in this case will increase slightly. The process of installing waterproofing material looks like this:

  1. A section of sheathing is cut out along the top line of the opening; its width is measured according to the dimensions of the drainage gutter.
  2. The waterproofing film is cut along the opening. Slide the drainage gutter under the film and install it in the gap between the sheathing. In this design, water will flow not onto the window, but into the gutter.
  3. The apron is unpacked, laid out and its location is marked so that both the window and the roof are protected from moisture penetration. The apron is fastened with a stapler, the fastening points are frame, mounting beam, rafters, top sheathing. The apron is tucked under the sheathing, along the top line it is brought under the drainage gutter.
  4. After fastening the apron, the roof at the bottom of the opening is mounted again.

Installation of roof window frame

After laying the apron, the technology for installing dormer windows involves fastening the flashing. The process starts at the bottom and then moves up, the algorithm looks like this:

  1. At the first stage, the lower corrugated apron is laid, then the parts on the sides and the top, the last ones are installed on the windows.
  2. In these works, it is necessary to strictly follow the information in the instructions, since each manufacturer has its own distinctive points. This also applies to Fakro and Velux products; in some cases, roof windows are installed using a sealant. For example, Roto windows are equipped with a seal, under which you need to insert a flashing and fix it there. Fakro windows do not have such an addition; the frame is fixed on the frame, and is covered on top with special elements that mask the joints and connections.
  3. The flashings are joined and securely fixed to the frame and sheathing.
  4. The lower apron is fixed at the top of the roof.
  5. Upon completion of the work, a special element is attached to the flashing, creating a tight seal between the window and the roof.

The manufacture of the window opening in the attic is completed, followed by: Finishing work and equipping windows with sun protection elements. The cost of installing a turnkey roof window also depends on what materials are chosen for this. Do not use when sealing joints polyurethane foam, and purchase specialized sealants. The slopes for the attic window also have their own distinctive features, Bottom part the slope is always installed vertically, and the upper one horizontally. This design will ensure optimal movement of the warm flow from heating devices. As a result, condensation will not form on the glass.

Installation of a roof window, video tutorial:

Good afternoon and interesting reading!

Who would have thought that one of our school poor students at the next alumni meeting would show himself in a completely unusual way.

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

We talked to him and told him that the attic could be made more comfortable by installing slanted windows. He liked the idea and decided to contact our company.

This is how professional connections are made.

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

Installation of roof windows - instructions:

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

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

1. Dormer windows can be installed in roofs with a slope from 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.

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

If the roof is covered with a 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 flashing.

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

4. When installing on rafters, the window is attached to the rafters using mounting angles.

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

Helpful advice!

If 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 placing the transverse beams 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 designated place with a margin of 10 cm on each side, so that you can then attach the hydrobarrier to the window frame.

Cut out part of the sheathing in the prepared area. To install the drainage gutter, cut out fragments of the counter-lattice and cut the hydraulic barrier at an angle.

6. Remove the aluminum trim profiles 1 and 2 from the window packaging. Disconnect the lower trim profile 3, as well as the shipping 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 its bottom edge on the floor and tilt it easily. Open the window and turn the sash 150°.

Holding the window in this position, use a screwdriver to tighten the locking screws in the hinges three turns clockwise.

8. Remove the sash from the window in accordance with the indicated direction. Perform this operation carefully, while simultaneously removing the sash from its hinges. Failure to comply with this requirement may result in damage to the hinges.

9. Screw the mounting corners to the window frame at a distance of 10 cm from the edge so that they do not touch the roof sheathing.

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

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

Screw the mounting angles to the box so that the number on the angle ruler:

  • corresponded to the thickness of the sheathing;
  • coincides with the groove of the selected window seating depth.

The selected window seating depth (N, V or J) must correspond to the designation on the flashing packaging. Installation of a skylight with continuous sheathing carried out similarly to installing a window on the rafters.

10. Install the window frame in the prepared area of ​​the roof. The mounting angles must rest on the rafters. Check whether the groove on the window frame coincides with the top plane of the sheathing.

Use a level to check the horizontal position of the bottom edge of the window. If necessary, place a wedge under the corner to establish a horizontal line. Screw only the lower corners to the rafters.

11. Insert the window sash into the window frame.

To do this you need:

  • take the sash in your hands, i.e. the outer glass towards you, and the bottom of the window up;
  • holding the sash in vertical position insert it from the outside into the loops evenly without distortion;
  • Unscrew the locking screws three turns counterclockwise and close the window.

12. Open the sash slightly 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 angle on 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.

Note!

If a water barrier is used during the construction of the roof, it is necessary to install a drainage gutter above the window.

14. If a water barrier is used during the construction of the roof, it is necessary to install a drainage gutter in the prepared place above the window to remove condensed moisture away from the window, and also attach the water barrier to the window frame.

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

Dormer windows are those that are installed directly into the roof.

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

So, roof windows are a structural part of the roof. In view of this, they must meet all the requirements specific to load-bearing elements in terms of reliability, strength, water resistance.

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

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

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

The universal one also helps with this. mounting system and the availability of various configurations. Greater light transmittance and small window openings provide better illumination.

Suitable double-glazed windows were invented especially for different regions: for cold climates - multi-layer, energy-saving, for hot regions - mirrored, 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 or colored glass.

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

Velux windows

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

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

Among the advantages of roof windows from this company we can highlight them:


Fakro products

The Fakro company manufactures roof windows from laminated wood based on pine High Quality. During the production process, the wood is treated with an antiseptic and coated with varnish in 2 layers.

She's protected on the outside aluminum profile, coated with polyester.

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

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

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

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

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

The German company ROTO-FRANK invented Roto roof windows, which can withstand the same load as the roof. Due to their special design and salary (under different types roofs) junction points will never leak.

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

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

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

In addition, it expanded color palette overlays, and anthracite metallic was added to the standard colors. All junctions between the window and the roof are equipped with special seals, locks and other elements.

Which roof windows are better: Velux, Fakro or Roto

Comparison of composition

Velux products are made from northern pine - very dense and durable material. It is a laminated veneer lumber coated with a fungicidal and varnish composition (2 layers).

Note!

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

Fakro 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 in the form of laminated veneer lumber is used. Depending on the model, it can be two- or three-layer with the application of fungicidal impregnation and varnish coating.

Double-glazed windows

Velux structures have energy-saving double-glazed windows produced using modern “warm perimeter” technology.

The weakest point of conventional 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 glass unit of the attic window there is an inert gas - argon, the loss of which is prevented by silicone sealing (instead of butyl sealant). Double-glazed windows of Velux windows can withstand frosts down to -55 degrees.

Fakro windows use energy-saving glass units filled with argon, resulting in attic room will be warm and cozy all year round.

The glasses themselves have increased strength, resistant to extreme weather conditions. Thanks to special fuses, the glass unit is protected from extrusion and breaking.

Roto roof windows consist of single-chamber double-glazed windows, the glass of which is 4 mm thick. Argon (krypton) is pumped inside it, which provides high thermal insulation.

The glass of some models is tempered to increase its strength characteristics.

Opening windows

Velux frames open very easily using the handle at the top of the frame. Thanks to this, you can place them on optimal height(up to 110 cm from the ceiling), which will provide good review even a sitting person, even a standing one.

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

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

Roto products have a mechanism that allows them to be rotated along two axes. Opening the window along the top axis provides an excellent view and at the same time prevents you from getting wet in rainy weather.

When using special fittings, you can lock the doors at 4 points, which will protect you from burglary.

Ventilation characteristics

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

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

Dormer windows from Fakro and Roto have similar ventilation valves, but in terms of design they are slightly inferior to those from Velux.

Installation features

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

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

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

There is also nothing complicated in their installation if it is carried out on the sheathing, because there is no need to adjust the pitch truss structures to the size of the window.

Roto structures are also easy and simple to install on various roofs. They are attached to the sheathing, but you can additionally secure them to the rafters thanks to the mounting angles.

Tightness

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

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

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

Window accessories

Windows from 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 system (electric, solar powered).

Thus, having considered the 3 main manufacturers of roof windows, you can make the final choice, which will remain only yours!

Do-it-yourself installation of roof windows

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

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

How to install correctly

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

1. First of all, remember: the attic window is not attached to the sheathing, but to the rafter system (vertical rafter beams).

2. If in the design rafter 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 sheathing slats.

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 level the roof window.

4. To facilitate installation, you can under bottom windows, install a horizontal beam to the rafter system.

5. Installation of a roof window. We level the bottom of the window and screw the corners (not all the way) with self-tapping screws (should be included in the kit).

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 angles (also not completely, so that later you can accurately adjust the position of the window frame).

7. When the dormer window is already supporting itself, 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 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 sides of the frame.

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

First, the bottom portion of the material is fitted to the overlapping frame, and a cut is made in the side flanges to fit them to the roof. Then the side insulation sheets are added and overlap the sides of the frame.

The upper and lower protruding parts are cut from below and above and placed under the first lower insulating sheet, and on top of the side of the box.

The top sheet is laid in the same way as the bottom one, only on top of the sidewalls (cuts on the edges are made so as to overlap them with 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 attic window you need to nail a thin strip in order to attach a soft corrugated apron to it, which will smoothly lie on the profile.

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

11. Setting salaries. First, remember: if your frames are fixed with latches, clamps or latches, then additional mechanical fastenings(nails, screws) are not required.

Just like with insulation, the lower flashing is installed first (on top of the roof). A fixing plate for the attic window is placed on top of it. The flashing and overlay are secured using 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 it stops (special cuts can be bent outward to strengthen the fastening).

Side flashings are also nailed to the window frame, and to the sheathing or rafters using clamps.

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

In front of the top flashing, you need to install linings on the attic window and screw them with self-tapping screws through special holes. The top flashing is installed simply: it is screwed to the sides of the window with self-tapping screws, and secured to the sheathing with clamps.

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

And on top of the roof you need to put it on the flashing with a distance of 6-10 cm from it.

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

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

15. Window insulation can be done from the inside by inserting insulation around the perimeter (mineral wool) and covering it from the outside with a foil heat-insulating layer from condensation. Insulation is also installed on the sides of the slopes.

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

In places where the vapor barrier apron comes off, you can make additional fastenings with self-tapping screws or sealant.

As a rule, rough slopes are installed in the attic window, which are subsequently covered with the overall finishing of the room. Making such slopes is not difficult: 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 slope looks horizontally. Attics with sloping roof may not have strong slopes.

Note!

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

It is worth considering that from different manufacturers Installation methods for roof windows may vary slightly. We will look at them separately in the future.

Installation methods will also be discussed. various types roof windows and accessories.

Installation of roof windows

Dormer windows are installed in roofs. Such windows differ significantly from façade windows in design, installation and operation principles.

The main parameters affecting the operation of roof windows:

  • installation of a roofing pie;
  • correct installation;
  • operation in winter;
  • microclimate.

Roofing pie device

According to the instructions of most roofing material manufacturers, insulated roofing pie should consist of the following layers (from top to bottom):

  • roof covering (metal tiles, flexible tiles etc.)
  • lathing under the roof covering (solid or stepwise; installation of roof windows is carried out on this layer)
  • ventilation gap (most often formed by a counter-lattice above the diffusion membrane)
  • diffusion membrane (permeable to steam from inside the room)
  • wooden rafter legs, insulation
  • vapor barrier
  • rough filing

For more details, see the manufacturers' instructions.

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

Roof windows Velux, Fakro, Roto

It is optimal that the installation of windows, be it Velux, Fakro or Roto windows, is carried out by specialists who have experience in this type of work and know the principles of constructing a roofing pie.

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

If you decide to install roof windows yourself or hire 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 preparing the opening. The width of the opening for installing a roof window should be greater than the width of the window: for Velux - by 4 - 6 cm (better 6 cm), Fakro - by 2 - 5 cm (better 4 - 5 cm), Roto - by 6 - 7 cm (better 7 cm).

The height limit will depend on the shape of the slopes. For an “open” slope (the lower slope is vertical, the upper slope 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 in an “open” shape, because it provides better window ventilation and better illumination.

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

For proper installation of a roof window, the window frame must be leveled. If the slope is not level, you can install wedges, usually included in the kit, under the mounting brackets.

Also, the window frame should not be beveled from rectangular shape. To do this, you need to install the rotating 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 properly insulate the “bridge” between the roof insulation and the window frame.

When installing a roof window, it is optimal to insulate this place with the material included in the installation package:

  • Velux - thermal insulation belt made of polyethylene foam
  • Fakro - sheep wool insulation blocks
  • Roto - integrated thermal insulation belt made of polyethylene foam

When installing Velux or Fakro roof windows, insulation of this area can be done using mineral wool, penofol and other materials (spray foam cannot be used), but this is more difficult and can lead to a decrease in the service life of the window.

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

Salary setting. Performed according to the manufacturer's instructions, differs depending on the roofing covering. The integrity of the flashing strips must not be damaged (for example, by drilling with a self-tapping screw when attaching metal tiles around the flashing).

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

Helpful advice!

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

When installing branded slopes, a 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 a guide to installing roof windows.

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

Installation of Velux roof windows is a matter that should be approached with all responsibility. Windows can be installed either in a roof under construction or in finished roof. But either a certified professional or a person who has high skills in high-quality performance of any kind can do this correctly. construction work. If you entrust the installation of Velux windows to an amateur, you expose yourself to a great risk of receiving poor-quality installation. As a result, you will be faced with 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 are included with each product. Next, you need to choose a suitable place where the window will be located. At this stage, careful measurements should be taken and the contours of the future window opening should be noted. Be sure to take into account that the dimensions of the opening should be 60 mm wider than the window and 45-50 mm higher than it. Cross beams in the plane of the rafters, it is advisable to install it at a distance of about 20 cm from the window, so that in the future you can make the upper and lower window slopes"open" form. The installation of Velux windows depends on another important factor - the angle 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 from below - no lower than 110 cm. All these calculations will help you achieve greater safety and convenience when washing windows, as well as provide excellent visibility as in standing and sitting position. Now you can remove the casing and cut a hole in the insulation and waterproofing material according to the applied markings. The material should not be removed completely; it can be rolled inside the attic to be used 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 inside the room), and then fix the frame on the sheathing or rafters using the brackets included in the kit. Pay attention to the bottom edge; it should not interfere with future installation of slopes. Do not secure the top brackets until the alignment is complete. Be sure to ensure that the bottom of the box and the swing frame are parallel to each other. Upon completion of this stage, level the structure again and secure the upper brackets.

To provide reliable protection from the cold, you should place a belt made of foam polyethylene on steel frame. If you have not purchased a proprietary installation kit for installing Velux roof windows, you can perform thermal insulation using mineral or basalt wool, as well as penofol. If desired, nail it on top with staples, but usually the insulation is supported by the insulation laid below, which, in turn, is located on the vapor barrier. The special kit also includes a moisture-proof apron that prevents the penetration of moisture. It must be secured around the perimeter of the frame, bringing the edges under the sheathing. The upper edge of the insulating apron must be placed under the drainage gutter. To install it, cut openings in the counter-lattice above the window, and trim 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. This way, roof condensation will not flow onto your window.

You should move on to this stage of work only when you have finished installing the window frame and installing hydro- and thermal insulation. The flashing consists of frame gutters and overlays. It performs several functions: fixes the insulating apron and seal, provides high protection from precipitation, and also gives completeness window design. Installation of the flashing is carried out using special clamps in a certain order: the bottom bar, then the side sections, and finally top part. Upon completion of all stages of work, you can insert the sash back into the frame box. This can be done using the locking button, which is located on the rotary hinge.

The final stage, which includes the installation of Velux roof windows, is finishing 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 in the room. In addition, if the lower slope is placed vertically and the upper slope is installed horizontally, then you will achieve excellent air circulation. The assembled slopes are secured with locks. To avoid getting the insulation wet, it is necessary to properly seal the junction of the vapor barrier of the slopes with window frame and roof vapor barrier. The gaps between the slopes and the wall should be closed with platbands.

If all installation work was carried out professionally and efficiently, then you can be confident in the reliability of the windows and their long service life.
