Standard sizes of Velux, Fakro and Roto roof windows

The roof window is a special element in the roof structure. As the name implies, it is installed in the roof with an attic room. The main distinguishing feature of such windows is their ability to withstand the same loads as the roof of the building. For this reason, the design of such a window is slightly different from the vertical windows we are used to in the walls of houses and apartments. In this article we will tell you what sizes of roof windows are most common.

Choosing a roof window: which manufacturer should you trust?

You understand that a roof window is what you need! You have long dreamed of reconstructing your attic and finally decided to do it. But you don’t know how to choose the right roof window. Does the crisis, the need to count money during repairs, literally force you to take a closer look at ordinary, cheap sloped PVC windows? Stop! Stop! There is no need to sacrifice comfort in your home, because you build it once and for the rest of your life. So how do you choose a reliable manufacturer and still stay within your budget? We'll tell you in the article.

By form:

Dormer windows are produced in wooden and plastic frames. The choice depends on what room the attic will be used for. If you decide to arrange an office, a nursery or a guest room there, then a roof window in a wooden frame will look the most aesthetically pleasing. If you have a bathroom or kitchen planned in the attic, then it is better to opt for a plastic attic window. It will perfectly cope with moisture indoors and prevent the appearance of mold and mildew.

Market leader

If you ask yourself who produces roof windows in our country, then remember 2, or at a stretch 3, manufacturers? And the point here is not at all that the brand is advertised. In the Russian market, there are really only 2-3 companies that produce roof windows.

This is due to the complexity of production technology. It is different from the technology of creating vertical windows. It is not profitable for companies that specialize in classic windows for the home to also deal with attic ones: it is necessary to introduce additional equipment and comprehend engineering subtleties; plus, achieving a truly high-quality product can only be achieved over time, when window models pass quality tests under real operating conditions.

Therefore, it would be a mistake to turn to manufacturers of vertical (wall) structures for roof windows. You risk purchasing a low-quality product.

The leading manufacturer of roof windows always has a wide range of models. The choice of sizes is large, but they are standard. The factory has established production of models of each size. When the creation of all parts is carried out on the latest equipment, by craftsmen who know their business, and the assembly is completely factory-made, real quality is achieved.

In addition, it is not profitable for large manufacturers of vertical windows to deal with attic windows, since they realize that they will not be able to maintain the level of quality in the production of attic windows at a level corresponding to their reputation. And young companies initially produce designs with low quality characteristics, because they have neither decent equipment nor engineering solutions of the required level.

Which windows to choose for the attic, plastic or wooden?

Which windows are better: plastic or wood? Eternal dispute. If your wooden windows are quite old, this is not a reason to replace them. If they are made of high-quality wood and installed in compliance with all technologies, it is quite possible that they will not cause you dissatisfaction despite their “mature age”. Although, of course, plastic double-glazed windows are more durable and practical.

If previously the roof window was wooden, tightly embedded in the roof and most often did not open, then modern options are very diverse. The concept of an attic in a country house or dacha has now disappeared from our everyday life and concept. If earlier this area served to collect all sorts of unnecessary rubbish that we were sorry to part with (but how many interesting things we found there in childhood, when we came to our grandparents!), then the modern attic is a separate, comfortable room for living - an attic.

Cost of dormer windows

From all of the above, the second mistake follows when choosing a manufacturer of roof windows. The skeptical attitude of most people towards a market leader is associated with a false stereotype: if a company is famous, then its products are very expensive. This is absolutely not true.

For example, VELUX is known to almost everyone simply because this company has been on the world market for 75 years, and has been creating windows for the harsh climate of Russia for 25 years. At the same time, the cost of roof windows from this manufacturer is affordable for everyone.

Let us remind you that the same requirements are imposed on the quality and reliability of dormer windows as on the roof: the windows must withstand snowfall, rainfall, large hail and falling branches.

Therefore, you need to pay attention to ensuring that the outer glass is especially durable - almost all manufacturers use tempered glass. And if the window is installed so that the people in the room are directly below it (for example, above a table or bed, in a children's room), then it is important to provide additional protection against splinters in case the window does break. Not all manufacturers have this option.

Almost all VELUX window models use a safety glass unit with external tempered glass and internal triplex glass (this technology is used for car glass) - even when broken, the fragments remain on a special film and do not fly apart. With all the advantages, the price remains attractive; and the products are always in stock.

Most others need to be ordered in advance and are significantly more expensive.

When you buy VELUX roof windows, you can be confident in their quality. There is a simple benefit here: you pay a little extra, but instead of a dubious product you buy reliable and beautiful windows.

What types and sizes of windows are suitable for an attic?

The size of the dormer window depends on the distance between the rafters on the roof and the length of the existing slope. The width of the window should be 4-6 cm less than the width between the rafters; if this distance is greater, then it’s not a problem, it is possible to install additional rafters; worse, if the width of the glass unit is greater than the distance between the rafters, then you will have to remove part of the roof.

It is necessary to take the choice of a roof window seriously. It should be taken into account that it will be located on an inclined plane, which means the load on it will increase, so you should purchase a reinforced frame; such a window should have good thermal insulation, higher than that of a simple window. Clearly select the size so that there is comfortable lighting in the room, but also fits the size of the roof of your house.

You can use a bag with two glasses; in addition, you can order it tempered, which makes it more durable.

There are types of windows with vertical installation, installed in a separate frame and they can be tilted depending on the slope of the roof. The most popular method of installation in the roof at an angle of its inclination. Such windows are called inclined.

When installing roof windows, it is important to ensure complete waterproofing; for this purpose, they are usually equipped with a flashing made of waterproof material, which will protect the window structure from leaking during rain.

For a more comfortable view, the lower edge of the window should be installed no higher than one meter from the floor, and the upper edge no higher than 2.20 m from the floor.

Types of opening roof windows

The type of solid windows does not allow them to be opened. They are the cheapest, but not the most convenient.

The version
with central pivot opening is equipped with a special friction mechanism and allows you to rotate the sash up to 180 degrees.
This gives you a good opportunity to reach anywhere on the window and wash it. But the downside is that they take up space when open, and there is no possibility of a convenient approach to them.

There are windows equipped with blocks with two axes of rotation , central and upper. They are very comfortable, but due to the accessories the price is higher.

A very interesting solution is a balcony window for the attic. Part of the window moves forward, and part rises, and on top of that, railings appear. The most expensive option, but it looks very nice and is easy to use; it is possible to open them completely and go out onto a small area.

Smart windows are equipped with rain sensors. And if you forgot to close the window and it starts to rain, it will handle it itself.

False economy

There is another mistake that many people make: a complete refusal to install window structures in the roof. It arises, perhaps, because the owner does not fully understand the feasibility of purchasing windows for the attic.

Usually the choice on the scale is between immediate savings and additional comfortable living space. After all, the second floor without attic windows is a dark room that looks more like an attic than cozy rooms.

In the meantime, furnishing living rooms is exactly what is worth investing in. Cost of 1 sq. meters of real estate is growing every year. And refusing to install skylights is a false economy. You not only deprive yourself of the opportunity to live in a bright room, but also significantly reduce the cost of your property.

Installing double glazed windows in the attic

You can install windows, including attic ones, yourself, but you still need certain skills. Instructions for installing roof windows are always included with them. The scheme is always the same:

1. It is necessary to prepare a hole in the roof, observing the dimensions of the window.
2. Next, waterproofing and surface leveling are installed.
3. The glass unit must be removed from the sash by disconnecting the glazing beads.
4. The next step is to install the frame; leveling is done using a level and pieces of wood or plastic.
5. After installing the frame in the opening, it is secured with brackets, the lower ones tightly, and the upper ones should still have the ability to adjust along the vertical axis.
6. If there is a misalignment, it is necessary to level the structure so that the mechanism opens and closes easily.
7. After firmly fastening, insulation is laid around the edges, and the entire structure is protected around it with a waterproofing “apron”, which is included in the kit.

The main thing is to comply with all the requirements according to the instructions and complete tightness. If there are small children in the house, it is better to protect any windows with additional locks that do not allow children to open them on their own.

Any of the windows can be supplemented with mosquito nets, which will protect you from insects. Installing them is not difficult by attaching special plastic ears to the window frame. You can order the mosquito nets themselves in any size to fit your windows from a company that manufactures and installs windows.

You can install roof windows yourself, but it’s still better to use the services of a specialist, which will give you greater confidence in the quality of the work and additional guarantees; if any deficiencies are found, the specialist will fix everything without additional payment.

Innovative product

To turn your attic into a truly paradise, install sloping windows in your home that meet all modern requirements.

Before you give preference to one or another manufacturer, pay attention to the ease of choice, the model range, and the innovations that it offers.

For example, VELUX recently launched a new generation of roof windows on the market with 10% more glazing area, while maintaining the same familiar and convenient dimensions. Plus 10% to the glazing area means 10% more light on your additional living floor.

The design of the windows also compares favorably with the appearance of other models. Natural polished wood, elegant window frame, rounded corners and smooth lines. The new generation VELUX skylights will decorate any interior style.

New VELUX window models are developed in accordance with world quality traditions specifically for the unpredictable Russian climate. At the same time, the manufacturer managed to adapt the cost of windows to the needs of Russian buyers.

Installation instructions for Fakro windows

The window frame is made of four bars. Recommended distances:

• from the edge of the sheathing to the bottom bar - 12 cm;
• the top bar is installed at a height equal to the height of the window plus 1 centimeter;
• on the side, 5-6 cm is left between the roofing material and the frame;
• on top between the frame and the roof - depending on the roofing material: up to 4 cm for flexible tiles, 9 for metal profile sheets, 12 for ceramics.

If the gap is too large, it is closed with an additional row of roofing material. The high profile is cut so that the edge does not damage the flashing apron.

note

When installing roof windows, foam is not used because it is vulnerable to ultraviolet radiation.
Only sealant. Installation of Fakro roof windows is carried out from the attic side. Procedure:

1. Cut a rectangular hole in the vapor barrier film smaller than the window - leave a margin of 10 cm on each side.

2. Cut out a fragment of the sheathing and covering, if it is laid.

3. To install a drainage gutter, cut the waterproofing film obliquely and cut out the counter slats.

4. Remove the sash from the frame. How to remove a Fakro roof window: rest the frame on the floor, open the sash slightly, press the pins, remove the sash from the bottom up.

5. Attach the mounting angles to the frame from the sides in accordance with the N/V/J/ markings.

6. Install the frame into the opening, check that the installation is horizontal along the bottom edge.

7. Secure the lower corners to the box. Grab the top ones, but do not tighten them.

9. Make final adjustments to the Fakro roof windows so that the gaps between the frame and the frame are the same on all sides. Plastic wedges are used for leveling. The outer edge should coincide with the outer surface of the sheathing.

10. Tighten the fasteners at the upper corners.

11. On a large window, intermediate fasteners are additionally installed on the sides of the frame.

12. Place one edge of the waterproofing apron onto the frame walls and secure with a stapler. The second one is brought into the room and secured from the inside with a stapler to the sheathing.

13. Install a drainage channel above the top edge of the frame. Place the roof insulation over the gutter.

14. Attach the lower part of the frame to the window and secure it with screws.

15. Place the side flashing strips under the linings on the box and secure them in the overlap areas.

16. Place the top bar under the side bars, secure it, coat the joints with sealant.

17. Secure a heat-insulating and vapor barrier apron from the inside around the perimeter of the frame.

18. Install slopes: lower – vertically, upper – horizontally.

8. Return the sash to its place.

Technology

And finally, let’s talk about the manufacturability of installing this type of window. When choosing a manufacturer, you should pay attention to the ready-made solutions for installation of the structure that the company offers.

In order for the window to serve you faithfully for more than a dozen years, you need to carry out heat and waterproofing according to all the rules:

• Install external flashings that guarantee a reliable connection between the window and the roof;
• Connect the hydro- and vapor barrier around the window with the hydro- and vapor barrier of the roofing pie;
• Be sure to insulate the space around the window;
• And don't forget about the internal slopes.

When all the parts and materials for installation are “native” for the window you are installing, this gives you a double guarantee of quality.

Firstly, because branded kits for thermal and waterproofing, protection elements and other devices fit perfectly together, guaranteeing a reliable connection between the window and the roof. Secondly, the entire technology as a whole and individual components of the design have passed quality checks. Only a large manufacturer that has its own research center can afford such quality control. For example, VELUX tests the air and water resistance of its models in a wind tunnel. And conducts more than 1000 different reliability tests.

The new generation VELUX windows are divided into three model ranges: VELUX OPTIMA Standard, VELUX OPTIMA Comfort and VELUX PREMIUM for easy selection according to price parameter. All VELUX double glazing units are filled with inert gas and feature Low-E coating for improved thermal insulation.

The VELUX company does everything for your safety and comfort, and is confident in the quality of its products, therefore, if branded installation accessories were used during installation, the warranty on attic windows is 10 years.

Rating of the best manufacturers of roof windows

Velux

Velux has been operating in the window market for over 78 years. The brand began to explore the vast expanses of Russia since 1991. Today, the Danish manufacturer occupies a leading position in our country. Our own developments are quickly implemented thanks to new technologies and modern equipment. The production cycle uses only high-quality materials that meet modern environmental requirements. Experts note the energy-saving designs created by Velux employees. They allow you to provide a warm perimeter in the room. Therefore, in winter the room remains warm, and in summer the air remains cool.

The brand becomes the winner of our rating, because users have no special complaints about the quality. The only downside is the high price.

Advantages

• high quality;
• Beautiful design;
• energy-saving designs;
• practicality.

Flaws

Fakro

The quality of the Fakro brand products is not inferior to the rating leader. It is not without reason that on thematic forums users actively compare these two brands. The Polish company appeared in 1991 as a small family business. Today, Fakro roof windows are in steady demand in the European market. A wide range of materials, both artificial and natural, are used in production. You can choose windows for your attic roof of any size. Experts appreciated aluminum windows. The design includes special bridges that retain heat. In addition, such window systems are lightweight, which is important when installing a roof.

As for the weaknesses, professional builders note certain installation difficulties.

Advantages

• high quality;
• stylish appearance;
• ease;
• reasonable price.

Flaws

Roto roof windows stand out from competitors due to their increased moisture resistance. For manufacturing, the manufacturer uses environmentally friendly plastic and durable seals. Therefore, condensation does not form. The plastic is UV resistant, practical and easy to clean. The German company's catalog contains double-glazed windows of different sizes. The most popular designs in Russia are 3 or 4 chamber designs. The brand has earned praise from experts for its reliable protection of window systems against burglary. Even professional burglars will have trouble dealing with the intricate fittings.

Users speak flatteringly about the quality of the windows and their resistance to weathering. The disadvantages include the instability of the mechanisms to low temperatures.

Variety of choices

In addition to the companies represented, there are products from other competitors on the market, for example, Roto. Therefore, when choosing which is better - Velux, Fakro or Roto or products from another manufacturer, you will have to thoroughly study the features of each product. First of all, in order to choose the right windows, you need to decide what function they will serve; for example, if you want to create a bright room, then the windows should be quite large.

Not all manufacturers produce non-standard large windows. If you need to take care of lighting the bedroom, the light there, on the contrary, should be dim, so you may be interested in a small window. In addition, many manufacturers offer a wide range of fittings, which determine the method of opening the window and the structures themselves. Before purchasing, it makes sense to compare products from different manufacturers, for example, Fakro and Velux, in order to give preference to the one that, in your opinion, will best meet all your requirements. Almost all brands produce products to order, so you can choose the desired type of design and size.

The Velux company has been known on the world market for 69 years. This brand has become known in Russia since 1991, and is currently one of the leading brands in the country. The company constantly pleases customers with new technologies that it develops independently. By contacting specialists when choosing Velux and Fakro, you can be sure that they will quickly and competently assemble the necessary roof window for you that will suit your type of roof. It is worth noting that the company also produces branded fittings, which not only fit perfectly with the product, but also ensure its durability and strength, because it is the quality of the fittings that determines how long any window in the house will last and how reliable it will be.

Installation of windows from this company is not difficult, since the manufacturer has thought through the design well, making its installation as easy as possible. In addition, the company produces a large number of accessories that may be required when installing a window. You can purchase branded elements for sun protection, mechanisms that allow you to control Velux/Fakro roof windows from a distance, and a variety of double-glazed windows.

Such systems are designed for different types of roofs. The range includes anti-vandal windows that will help protect the premises from illegal entry or attempts to break the glass mechanically.

• To produce windows, Velux uses high-quality materials that meet all environmental requirements. For example, the wood used undergoes special treatment; it not only creates a special microclimate indoors, but also lasts a long time, as it is protected from the effects of fungi, moisture and other harmful external factors.
• Using modern technologies, the company was able to create energy-saving structures that create a so-called warm perimeter in the room, thanks to which the room retains warm air in winter and cool air in the summer. At the same time, condensation will not form on the glass, which will harm the decoration of the room and the roofing pie. The distance between the glasses is filled with argon or other gas, which improves the insulating qualities of the double-glazed window, making it quieter and warmer.
• All of the company's products are thoroughly tested before they hit the market, which is important to consider when deciding whether it is better to buy Velux or Fakro. A small pleasant addition to all window models is the presence of a special valve for ventilation. This allows fresh air to enter the room in any weather, without creating a draft and the room does not become colder.
• A special filter in the ventilation device prevents dust from penetrating into the room.
• A distinctive feature of this type of roof windows is the ability to use them in almost any climatic zone of the country, since they are able to withstand critical frosts.
• In addition, the products are well suited for areas where gusty, even hurricane-force winds often blow. The manufacturer offers a large number of models to suit absolutely every taste.

What should you consider when installing windows in the attic?

Unfilled slopes on windows, for example made of plasterboard, will do a poor job of ridding you of street noise; the sound in the voids of the slope will vibrate and, because of this, only intensify. The slopes must be rigid, without voids. And this is a condition for any windows, be it wood or plastic.

When installing attic windows, it is very important to have high-quality double-glazed windows, fittings and proper installation. To do this, it is still better to seek the services of a specialist. It is advisable to lubricate the fittings at least once a year and treat the seals with oil or glycerin.

If plastic windows were installed before carrying out dirty work, make sure that dust and dirt do not clog the fittings, and that construction foam, plaster, and paint do not get on the glass and frame. They will be difficult to remove without scratching the surface. It is better to protect them with some kind of cloth or film before starting work.

When installing a stretch ceiling indoors, a heat gun is used, and the temperature rises very strongly so as not to harm the plastic on the window and fittings. To avoid these troubles, it is better to cover the window along with the frame with film and place it in a ventilation position.

When installing roof windows, it is important to ensure complete waterproofing; for this purpose, they are usually equipped with a flashing made of waterproof material, which will protect the window structure from leaking during rain. For a more comfortable view, the lower edge of the window should be installed no higher than one meter from the floor, and the upper edge no higher than 2.20 m from the floor.

Many buyers who value classic style purchase Fakro or Velux wooden windows; which is better is difficult to determine immediately.

The peculiarity of the wooden model is that the pine or other type of wood used will not be a single piece. It is cut in a certain way, then dried and in the workshop they create laminated veneer lumber, the fibers of which are directed in different directions and impregnated with a special protective material. Due to this, the wood easily tolerates temperature changes and mechanical stress, practically does not burn, does not dry out, maintaining high quality for the entire period of operation. In addition, Velux roof windows, like Fakro, are painted with a special paint that does not need to be renewed for several years.

All mechanisms are distinguished by high quality, durability, and low maintenance.

The sash can open 135 or 160 degrees, depending on the model. This allows you not only to conveniently open and ventilate the structure, but also to wash it. The windows are highly airtight; they do not let moisture into the house, even if there is heavy rain outside; the structure can easily withstand strong winds and help keep the house warm.

Many Velux or Fakro window models have a special valve that allows you to ventilate the room without opening the sash. This is not only effective in winter, since an open window will quickly make the room cold, but also as a preventive measure against burglary. An attacker will be able to get through an open window, but it is almost impossible to break into the structure through the valve. In addition, the company offers a large number of anti-vandal solutions and designs that make it possible to protect the system from hacking.

Which windows are better - plastic or wooden?

It is better to install wooden windows during repairs and construction after completing all wet work (plastering, pouring floors, etc.), since wood absorbs moisture very well, this can cause it to swell, deform and possibly further rot the wood. If wooden windows have already been installed, and you have “wet” and dirty work ahead of you, you should not cover the windows with polyethylene, as a large amount of condensation will accumulate under it and you will only make things worse for them.

Wooden attic windows can also be installed with any type of opening. With proper care of wooden windows, their service life is comparable to the service life of plastic windows - up to 50 years.

Yes, of course, caring for wooden frames is more complex and time-consuming. If the wooden frame is scratched, then it is necessary to carry out restoration so that the destruction does not go further.

Plastic double-glazed windows, compared to wooden windows, of course, have a number of advantages:

1. A small chip on a plastic window will not affect its further service.
2. Wood is a fire hazard, but plastic is not.
3. Plastic provides good protection from external noise and serves as good thermal insulation.
4. The more seals there are on the window, the greater the sound insulation of the glass unit.

Advantages of use

For the attic, plastic windows are very convenient to use, since they are more practical and do not require painting, do not deform, do not rot, and maintenance is simple and convenient. But modern wooden roof windows are also eligible for consideration for installation, despite all the advantages of plastic windows.

They are made from lamellas of coniferous wood; when dry, they do not deform and transfer the load to each other. But such windows have a high cost.

If you like to work with your hands, then working with wood will bring you nothing but pleasure. Any wooden surface needs care, so once every 3-5 years you need to remove the paint layer, clean it well, sand it, go over it with drying oil or primer, which will serve as additional protection. And color them again.

You can go over the frame with stain of the color you want and varnish it. They will serve you for a long time. If you are installing new windows in a house under construction, then wooden windows will have an advantage if you are thinking about environmental friendliness, because wood is a natural material, which means it is clean, forms and maintains the correct microclimate.

Which company is better to choose roof windows?

Dormer windows need to be selected at the stage of designing a house, because the requirements for them are more serious than for vertical ones.

If you are concerned about installing this type of windows some time after the construction of the house, then you need to know some of the nuances of their installation:

• according to established rules, the area of ​​the attic space divided by 10 gives the area of ​​the attic window and it is not recommended to exceed it;

• the lower the roof slope, the longer the window can be installed;
• decide on the type of window opening: a fixed opening axis can be at the top, middle and side;

• it is best to use a metal-plastic profile or from varnished timber (laminated veneer lumber) with a thickness of no more than 60 mm;
• The requirements for a double-glazed window (single-chamber, 2 glasses) come down to the increased strength of the glass (triplex or tempered) and the lightness of the structure itself. It is good if the glass is tinted with a special film, and the glass unit is filled with an inert gas - krypton, which will provide maximum thermal protection;
• The fittings must be durable and have anti-corrosion protection. Additionally, it’s a good idea to have roller shutters, ideally built into the double-glazed window, but external ones are also possible. You also cannot do without special clamps that make opening easier and fix the window at a given angle.

Among the manufacturers of roof windows, we can highlight the Polish manufacturer - Fakro, which produces pine windows impregnated with antiseptic preparations and coated with several layers of varnish (water-based acrylic). The glass is tempered, the space between them is filled with argon, the windows are equipped with fuses to protect against extrusion, have an anti-condensation valve, and there are models with hail protection (FTP - V). You can also note the Danish Velux and German Roto windows.

Structural features of Fakro roof windows

Window components:

• frame;
• sash with double glazing;
• internal slopes;
• steam/waterproofing aprons;
• heat insulating circuit;
• drainage gutter;
• salary.

Advantages of Fakro windows:

• installation depth varies. Can be installed almost flush with the roofing: this is better from a design point of view and leaves more space for thermal insulation contours;
• the minimum of thermal insulation contours is two, but it remains possible to install a third. Many models have three circuits initially. Fakro windows successfully protect the attic from the cold even at -55;
• almost all models are equipped with ventilation valves, many also have a slot ventilation function;
• convenient and functional fittings. The hinges allow you to fix the frame in 6 positions, including rotation by 180 degrees (convenient when washing the window);
