Skylights: features, types and installation specifics

How to make the attic comfortable, to ensure the free flow of fresh air and daylight here? I will answer these questions in this article. I will also tell you how to choose a window structure, which curtains or blinds are better to install on skylights.

Design features

A properly constructed laminated roof with windows does not accumulate condensate due to ventilation, but retains heat. And manufacturers equip these designs thoroughly. For example:

• tempered glass or triplex glass - energy-saving elements that let in daylight on the attic floor;
• sealed seals;

• durable frame, impervious to moisture, invulnerable to UV rays;
• shading devices - blinds;

• ventilation in 2 modes: winter and summer;
• protective equipment against dust, insects.
• remote control (which requires a cable connection).

When choosing a window, it is important to clarify whether the thermal properties correspond to GOST R 51380 and GOST R 51387.

preliminary calculations

Consider how to choose the optimal design of the roof window. In doing so, we take into account:

• all its tasks (lighting, panorama, insulation, drain);
• place for installation;
• type of roofing material.

You cannot place windows:

• on the slopes of the valley (groove), so that precipitation does not accumulate in the inner corners;
• near ventilation outlets and chimneys, so as not to collect condensate;
• at the junction with the walls - due to shading and moisture.

That is, the junction of the roof window to the roof must be free from other nodes of this roofing system.

The type of roofing material determines the installation method. Because its high relief also implies a high external salary.

Based on the floor area, we also calculate the glazing area: 10 m² of the floor is illuminated by 1 m² of glazing (for any window size). Installation of a window structure in a steep roof is advisable at a height of 1 - 1.4 m. Remember, architectural aesthetics suggests a lower limit of 0.8m and an upper limit of 1.9m.

The higher the skylights, the stronger the lighting. Although their location under the ridge will interfere with admiring nature. However, such an installation is good for sloping roofs - at 15-20º.

Large windows - a bright room!

Types of roof window systems

The main thing in planning is to decide on the choice of design, weighing the pros and cons.

Vertical (cuckoos)

The vertical window is mounted in remote structures-birdhouses, in gables or in roof slopes. Under such a glazed opening, I would recommend placing a heating device.

Let's determine which is better a skylight or a cuckoo:

• Cuckoo roofing is labor intensive, and slanted windows are easier to install.
• The vertical structure can become a problematic place on the roof: the cause of leaks, difficult snowmelt, drafts.

• Cuckoo skylights allow you to give the exterior originality and open up a lot of interior design possibilities.

Only the cuckoo is mounted in the house from a bar above the stairs leading to the attic - so as not to lean under the low sloping ceiling.

Inclined systems

Skylights on slopes are part of a multilayer roof. They provide unhindered snow drift, draining rainwater without getting inside, absolute preservation of heat in winter and coolness in summer.

This means that only a competent installation of skylights on the same level with the roof slope guarantees a comfortable stay in this room.

These systems illuminate the attic as much as possible with sunlight - 40% more than cuckoos. And the question: how to wash an inclined window is solved simply: using a magnetic brush.

In the photo - a magnetic brush

The pitch of the rafters also determines the size of the openings. After all, it is better not to violate their integrity. Then how to properly mount the window here? Specialists put structures at 7-10 cm narrower than the pitch of the rafters (for thermal insulation). And it is desirable that there are 2-3 such windows instead of one.

But how to install a roof window when a part of the rafter is forced to be removed? Here, for strength in the opening, they are horizontally fixed.

The window-balcony consists of two double-glazed windows connected by a metal-plastic profile and an exit platform. The structure is mounted, like any inclined one, into the roof slope.

Mounting specifics

Mounting technology is available, so do-it-yourself installation is also possible. The factory kit includes:

• fasteners;
• adhesive tape;
• mounting corners;
• sealant;
• waterproofing apron with a steam-removing effect.

It is important to place a gutter device above the top line of the window. Specialists make it from waterproofing material, bent in half.

Professional installation of skylights is carried out step by step:

• opening preparation;
• installation of a frame without a double-glazed window;
• laying insulation, waterproofing;
• fixing the gutter above the top of the window;
• salary setting;
• installation of double-glazed windows;
• interior design with waterproofing and slopes.

Opening device rules

Now I will introduce the installation rules:

• Along the perimeter between the opening and the frame, it is necessary to lay thermal insulation with an allowance of 2-3 cm.
• Leave a gap between the bottom of the window and the roof. Its value depends on the type of roofing. For example, for tiles - 9 cm.
• Between the top of the window and the roof, 4-10 cm are left. Then the wooden rafters will not warp it during shrinkage.
• Install a frame without a double-glazed window (manufacturers explain in their instructions how to remove it). Attach the box to the rafters or to the rails.
• The waterproofing is cut with an overlapping envelope that turns outward. Top covered with a waterproofing apron.

• The drainage gutter runs directly under the cut section of the waterproofing, then it is fixed on the crate at an angle so that moisture drains into the roof gap.
• Next - the installation of double-glazed windows and mandatory adjustment. The lower brackets are fixed firmly, and the upper ones are not screwed in for adjustment. This is the clearance needed to align and fit the plastic corners. Fasteners are tightened after adjustment.

The interior decoration of window openings should be in harmony with the lining of the attic. At the final stage of arranging the roof window, you can sew the curtains with your own hands. Or decorate with roller shutters and blinds - for inclined views, this is the best choice.

Conclusion

So, now you know that roof windows affect the functionality and durability of the entire roof, the architecture of the house and its interior decoration. The installation given in the article guarantees the long-term functionality of the structure. And aesthetics and charm will be provided by roller blinds for roof windows.

You will learn additional visual information from the video in this article (I once caught my eye and I attached it). You have ideas and questions - write in the comments, we will discuss!

Going to the site, the measurer often not only fulfills his direct duty, but also advises the client on construction issues, helps to navigate the choice of interior design. Of course, we have to talk a lot about the features of installing skylights. Sometimes the measurer is forced to dispel the customer’s vain hope for a certain result that the person saw in a magazine or TV show - since the initial data of the house and the financial capabilities of the client are very different from those of the owner, whose house or apartment turned out to be an inspiring picture.

Today we will get acquainted with the reviews of people who have already installed skylights and admire the results of transforming the space under the roof.

Since many nuances are taken into account when arranging an attic: the number of windows and the size of window openings, and the direction of opening, material of construction, etc., with the help of someone else's experience, you can avoid common mistakes and achieve what you want with less effort and money.

.

We are all familiar with attics since childhood. Who didn't "hide" there with Carlson and Malysh, reading about their joint adventures in the house under the roof? Or didn’t he “observe” Kai’s communication with Gerda, who also lived in separate attics and grew beautiful roses there? For the first time, the space under the roof began to be used as a living space from the second half of the 17th century, when the Frenchman Francois Mansart, a famous enterprising architect, drew attention to the empty “territories”.

Most European attics are made according to Finnish technology. In Russia, attics began to get involved relatively recently - with the emergence of interest in individual, affordable, durable and airtight housing.

For attics, it is typical when the windows are located in the roof. Because of this, the installation of structures, and the frame, must comply with certain technical requirements. The most popular manufacturers of roof windows for the European market are Danish Velux, Polish Fakro, German Roto. It is these names of firms that are most often found in discussions on thematic forums.

We study the disadvantages of skylights according to reviews

The most active discussions on the forums relate to various difficulties with the installation and operation of skylights. Sometimes in the dialogues there are also very negative statements from people who have suffered with the renovation of the attic.

About the advantages and disadvantages of skylights in the video:

Possible problems and solutions

Flow

“... In winter, snow marks on the window thaw and freeze all season, then it starts to flow. Ice builds up at the junction of the window and frame. And I also tortured the condensate - I clean the snow systematically, but the window is still crying ... ". In response to such statements, they often write about the suspicion that the window became problematic due to the installation by the owners themselves, and not by specialists. And this advice is difficult to refute - hire specialists to solve complex construction problems.

High temperature in summer

“... I would like to make it cooler in the attic of the parental dacha in the summer ...”.

You can fix the problem in one of the following ways:

• by building up a heat-insulating layer under the roof;
• using blinds, reflective film or curtains;
• change the shape of the roof so that in the summer the overhang shaded the window.

Price

“Everything suits in the attic window: it doesn’t blow anywhere, it fits well into the interior, it’s convenient to use. But the price! Twice the cost of conventional double-glazed windows.

Which manufacturer's products you prefer is completely your choice. If you want better quality, you will have to pay more.

What is the advantage of skylights: we study the experience of owners based on reviews

Attractive look

“Attic rooms have become much prettier. At night, all the stars of the world are yours!

Energy saving

“Attic windows were installed in the office and bedroom. Comfort and light just increased.

The statements of this user are also confirmed by scientists: due to the angle of location, inclined windows let in more light than ordinary ones, that is, standing vertically (about 40%).

Placement of the handle, taking into account the wishes of the user

It is better to choose the location for installing the handle, taking into account the age and physical characteristics of the inhabitants of the attic. For families with children, it is better to give preference to doors with handles installed in such a way that it is extremely difficult for children to use the levers without substituting a ladder or high chair. It is even safer to use handles with key locks.

accessories

For equipment, a separate type of fittings is needed and you cannot buy it at retail. It is produced by the same companies that produce windows for attics.

If you need to replace or update some element, the application must be sent to the window seller.

Despite the similarity with the fittings for ordinary PVC double-glazed windows, the attic has some technical differences.

Roof windows are a good option for arranging office and residential premises. What designs do users like and what to look for in order to be satisfied with their choice?

What problem might you face

The installation of skylights by non-specialists is an absolutely typical and growing phenomenon, given that the flow of complaints about leaks has been steadily increasing in recent years. And with the advent of heat, the number of dissatisfied will increase, since this is a natural phenomenon when the technology for installing windows at an angle is violated. However, leakage can be observed even after a flawless installation. What can cause moisture to seep under the frame?

“Yesterday we received a call from customer P complaining about a leak in the skylights. Moisture seepage is observed under the lower porch of the window sash. The caller claims that the installation of double-glazed windows was carried out by experienced specialists.

After arriving at the indicated address and inspecting, it turned out that the installation was really done professionally. The cause of the leak was an excess of snow mass on the outer surface of the window glass. Under the sun's rays, the snow thawed, and the resulting water ran down an inclined plane to the lower frame. With a decrease in temperature, the water solidified and increased the load on the seal. Over time, it deformed somewhat, and water was able to seep out a little.

The key to solving the problem is to clear the window of snow and eliminate all moisture on the glass surface with a simple wipe with a clean rag.

To restore the functionality of the seal, a lubricant in the composition with liquid silicone is required.

After a while, it turned out that the recommendation fully justified itself: the leak no longer appeared. The problem was eliminated with little bloodshed due to the fact that the attic window was installed according to the rules. If the technology were broken, then the owner of the house would have to incur much greater costs than was spent on calling and consulting a specialist.

About the technology of installing mounting windows in the video:

Real owner reviews of roof windows

Reading the dialogues on forums discussing skylights, it becomes clear that the leading topic of conversation is related to the problem of leakage. Someone claims that no one will be able to avoid moisture seepage, someone insists that double-glazed windows from a normal manufacturer can fail only if installed by a non-professional. Others argue that neither the brand name nor the qualifications of the installers will save from a leak - over time, even expensive double-glazed windows begin to let water through.

Problems

When you hear statements, the essence of which is “Velux windows or, say, ROTO windows serve for 10-15 years and have never leaked,” you start to think that today's double-glazed windows of the same companies are not made in Denmark or Germany, respectively, but somewhere in Egypt or even near the town of Starye Pyrki.

Where do legs grow for such a suspicion? It's simple: most of the skylights complaining about leaking roof windows assure that the structures were installed by specialists, and do not understand which workers. It turns out that the root of the problem is a factory defect. And the fact that double-glazed windows let water through not in the rain, but after the formation of ice, is a confirmation of this.

How does the leak occur in the latter case:

• due to heavy snowfalls, a snowdrift forms on the outer glass;
• after a thaw, under the melted snow, ice forms in the evening, reliably “biting” into the window frame;
• because of the heat from the window, the ice is gradually melting, but the water formed because of this has nowhere to escape - there is an ice crust on top;
• if there is a gap between the frame and the sash - if the assembly of the double-glazed window at the factory was carried out in violation of the technology - water seeps under the seal.

The sealant may also begin to let water through due to the long operation of the double-glazed window without preventive maintenance. If the water seepage is caused by the age of the seal, then the streams will leave dark smudges, and if the seepage moisture is transparent, then poor assembly is the cause of the problem.

So that over time a good seal does not lose its properties, it must be lubricated. But even careful care is powerless in the face of time - then replacing with a new one is the only way to avoid leaks. Interestingly, for double-glazed windows with sashes that open according to the hatch principle, sealing gum lasts longer.

Advantages

Of course, roof windows have a lot of advantages! No one has yet complained about their poor thermal insulation or drafts. Owners of the latest models of Aereco windows do not get enough of the presence of pre-installed systems in the form of a self-regulating inlet valve that provides ventilation.

There were rave reviews from the owners of double-glazed windows with wooden frames.

Unlike ordinary ones made of the same material, the first ones are absolutely not afraid of rotting, they do not peel off and do not require systematic painting, since they are treated with special impregnation and have a protective coating.

Users are pleased with the strength of skylight glass, tested in practice: among the dialogues of the farmhouse.ru forum there is a description of a mini-incident that led the narrator to financial expenses, but convinced him of the strength of the glass in such windows. Because of the lost key, the man was forced to enter the house through a locked skylight, the glass in which resisted attempts to break it for a long time.

Window owners also like the loyalty program of manufacturers FAKRO, Velux, ROTO to their customers, expressed in the ability to replace defective elements for roof windows for free.

Skylights: choice based on basic characteristics

Like any person who purchases a product, the buyer of a roof window expects the quality of an insulating glass unit to match the amount paid. Most of the special double-glazed windows for installation in the attic are affordable for a wide range of consumers, and at the same time please with democratic prices.

By purchasing this roof window, you get:

• goods with a high safety factor;
• a reliable product, whose functional characteristics will protect the room from drafts, low temperatures, excessive humidity;
• Durable construction with 10 year warranty.

Glasses of high-quality dormer-windows are made of triplex. In addition to strength, this material has a valuable property: upon a crushing blow, the glass does not scatter with splashes of fragments, but cracks, becoming covered with a web of cracks of various lengths, but remains in the window opening.

Skylight glass scatters the sun's rays, so inside the room the light will be pleasing to the eye and harmless to things that are prone to fading.

Details

If we were engaged in the construction of housing for ourselves with a frequency of 5-10 years, then when preparing the third project, we would have considerable experience in arranging houses to our needs. But since we accomplish such a feat much less often, we have to seek practical advice on many building issues. Next, we will present a lot of applied information about skylights, collecting valuable information with the help of Prozarovskaya Marina, who works as a chief engineer. If we missed something, then later we are ready to answer all the questions you sent.

In general terms

What is the difference between a roof window and a regular vertical double-glazed window? What are the advantages of the first? Is it possible to install an ordinary double-glazed window at an angle in a mansard roof?

The main difference between windows is their purpose. Vertical double-glazed windows are mounted purely in the window openings of the vertical walls of buildings for various purposes.

Skylights are designed for roof mounting, so they can carry loads similar to those experienced by a roof.

The procedure for installing windows in the roof also has a number of nuances that are not needed for installing conventional double-glazed windows.

The cost per square meter of a roof window and the difference in price between it and the usual one

The cost of roof windows is determined not by the number of square meters in it, but by the combined amount for all the elements that make up the structure. The larger the area, the more complete the equipment and the newer the model of the attic double-glazed window, the higher the price for it.

For example, let's say that a basic design without a salary with a size of 78 x 118 will cost the client 9,800 rubles. What is the purpose of salary? This is an element for connecting double-glazed windows with the roof of your house. If it is profiled, then you need to choose a special salary worth 4,150 rubles. But the indicated amounts are the price for each of the products. Work, additions in the form of kits that provide heat, hydro, vapor barrier, are paid separately.

In most cases, pine wood from our northern regions is used for the manufacture of skylights. This material is preferred due to its special density and heat-conducting qualities.

If you prefer PVC double-glazed windows, we recommend choosing Roto or Faktro products. Or take advantage of an absolutely innovative offer - choose structures made of wood coated with polyurethane on the outer layer. It protects wood from impregnation with moisture, is not afraid of heat, does not turn yellow and is resistant to mechanical stress.

Algorithm for mounting skylights in the video:

Why vertical windows are made using a different technology

They have different purposes and different volumes of loads. The roof must have the same heat loss coefficient over the entire area, therefore, the windows in the roof must be a reliable barrier to the escape of heat from the room.

Is sweating possible?

All modern double-glazed windows belong to building envelopes and have similar problems with condensate. Therefore, this manifestation of excess moisture can be observed even in the highest quality structures.

How to deal with the resulting condensate:

• thoughtful organization of air convection;
• creating a ventilation gap if the technology is violated when creating slopes.

The fact is that the upper slope of the attic window should be horizontal, and the lower - vertical.

Then the warm air flow rising from the heating element under the window opening will spread parallel to the roof window area. If the lower slope is horizontal, then there is a need for a ventilation gap from special gratings.

Special Requirements

Often these windows are hanging over the people who are in the room.

Therefore, the structures put forward special requirements in matters of safety:

• internal glass must be made of triplex, which will save people near the window in case of damage to its transparent elements;
• the outer panes must be of the tempered type which are much stronger than normal ones.

What is triplex technology - this is a complex of two bonded glasses with a layer between them in the form of a film. It is she who does not allow the glass to "explode" into fragments when it hits the window.

To get acquainted with some of the characteristics of a double-glazed window purchased or already installed in a permanent place, study the data on the plate located at the end of the window.

To get to it, open the sash so that its upper part looks into the room. Usually a plate with information of interest (class, type of double-glazed window, size) is located on the right. For more information about what you can find out by reading the information on the nameplate (tablet), find out in a special section.

How to use in hot season

In summer, the space under the roof is the hottest area of ​​the house. All the heat that comes to us with the sun's rays is directed to the roof. Understanding the source of the problem, roof window manufacturers offer to deal with it through the use of sun-reflecting glass, interior curtains, roller shutters, blinds, and awnings. When choosing the right option, remember that using roller shutters, you will be forced to illuminate the room with artificial lighting, since such protection will completely obscure the room.

If the roof has sufficient thermal insulation, then the atmosphere under the roof on a hot day warms up to 26 degrees. With poor insulation, this figure increases greatly and the presence of a window on the south side of the roof will only exacerbate the problem. All protective methods of reducing the amount of heat entering through the windows are able to reduce it by no more than a degree. Therefore, it is advisable to put windows in the roof, provided that its slope faces the north side of the world. Otherwise, in the summer without air conditioning in the attic will be quite tight.

Operation in winter

If the house is heated, then the roof windows will not freeze. But due to their sloping location on top of the glass, snow deposits can accumulate. If the precipitation is weak, then there will quickly be no trace of snow. And with significant snowfall, snowdrifts must be periodically shaken off so that the amount of light penetrating into the room does not decrease and the visibility of the windows does not decrease.

Due to the temperature difference outside the window and inside the room, condensation drops form on the glass. Flowing down, they can cause the formation of a mini lake on the floor under the window. If you do not know about this and do not visit the attic for some time, then you may be faced with the fact that a section of carpet, parquet or furniture located directly under the window becomes very wet. As a prevention of unpleasant consequences, you can use a thick towel or rug.

As for the difficulties with caring for skylights. Yes, they get dirty faster, because dust and dirt are better retained on inclined surfaces. However, it is easier to wash the sashes of such double-glazed windows because of their location. Provided that the window is located in the living room, and not high above the flight of stairs. In the latter case, cleaning without a telescopic mop will not be easy.

If you are afraid that children will try to use the roof window as a climb to the roof, use fittings with a locking system with a key.

Reliability and duration of the operational period

Based on the foregoing, we can conclude that when choosing a high-quality roof window, you will get a reliable and easy-to-use design that will please your eye and soul for more than one year. Manufacturers confident in their product indirectly confirm the quality of products with a twenty-year warranty on glass. At the same time, they emphasize the need for systematic lubrication of fittings accessible to moisture and recommend periodically refreshing the appearance of frames with paint.

What problems can the owner of a roof window face?

Do not believe that there are no problems with skylights? Correctly. Any design may not serve as flawlessly as we would like, if during its operation the recommended rules of use are violated.

For example, for a long service life of an attic double-glazed window, it is extremely important to follow the installation technology: take into account the angle of the roof, the level of the floor, professionally mount the structure in a permanent place. Often, if errors are made, they are noticeable even to a person who does not have experience in construction.

If the developer is inexperienced, an incorrect project was used when decorating the house, then the result may be, for example, the inaccessibility of a free view - when you can’t get to the window without a chair or you need to bend in three arcs to look out into the street. A similar situation is observed in the attic of one of the members of the forum. Given the parameters of the project, she ordered attic double-glazed windows measuring 78 x 140, and in practice the latter figure should have been 160 cm. As a result, to view the situation on the street, the owners of the room have to bend over, which is not very convenient, whatever one may say.

To avoid inconvenience, count so that the bottom edge of the double-glazed window is 80-110 cm away from the floor. A more specific guideline: when sitting on a chair, the line of your gaze, when looking straight ahead, should coincide with the bottom edge of the glazing. You also need to consider your height: if you get up, you should not be afraid of hitting the sash of an open window.

The following reminder will help you not to miss the choice of the desired design: when determining the length of the window, consider the angle of the roof. If the angle is 30 degrees (or 35), then there should be at least one and a half meters between the lower and upper edges of the sash. If you suspect that you can miss the size of the roof window due to errors in the project, then before choosing specific designs, do not be too lazy to measure the attic yourself or by inviting an experienced measurer. Then you will definitely be sure that skylights will decorate the room and allow you to admire beautiful landscapes without requiring unnatural body curves from you.

If the attic is located in a house with attic walls, then the expediency of double-glazed windows is in question. You will not be able to admire the views through them, except to study the sky. But save a lot on electricity. In general, the choice is always yours if you approach any task wisely.

About the use of roof windows in winter in the video:

The attic is a part of the house, which has recently been increasingly used for living space. The solution has a number of obvious benefits, although many owners are faced with the problem of creating an optimal indoor climate. One of the main elements of the space is the windows in the attic, which allow not only to improve the aesthetic component of the house or cottage, but also to expand the possibilities for the active use of additional housing.

Dormer window - a structure located on the roof, which simultaneously performs the role of the wall of the room. Based on the specific conditions and wishes of the owner, such a window can be represented by different options and sizes, differing not only in cost, but also in technical characteristics.

Aesthetic design of the attic space

Location options and their differences

Depending on the location, roof windows are divided into inclined and vertical. Vertical installation is carried out on the gables or in the mansard roof openings specially prepared for this. As for the inclined ones, they are placed on the slopes of the roof at an angle of inclination of 15-900 degrees.

Compared to vertical ones, such structures provide greater penetration of light into the room. It is important to remember that they should be positioned so that the distance from the floor to the bottom of the block is about 80-100 cm, and from the floor to the top - about 180-200 cm.

Inclined variant

Please note: According to the requirements of SNiP, the glazing surface should be at least 10% of the area that the floor has.

Design features and variety of choices

Convenient opening and ease of use

The windows in the attic also differ in their design features, for which they use the following characteristic:

1. Cornice - relevant in those attics where there is a high wall. Below, under the main sash, there is another, additional component with a vertical arrangement.
2. Balcony - there is a connection of an inclined and vertical component, which at the same time acts as a balcony parapet.
3. Inclined, having a lower element - the lower block in such windows is deaf, only the upper section is intended for opening.
4. Light tunnel - used in situations where there is another room above the attic, in which, in fact, a window is installed. The lighting of the room is carried out by means of a tunnel-pipe with a reflective effect, located at the outlet of the ceiling.
5. Extensions - the upper elements that perform a predominantly decorative function. They have excellent aesthetic data, harmoniously fitting into the interior of any attic. The design can be different, but often it is a round, semicircular or triangular window.

Plastic or wooden frames

For window blocks made of plastic, the following is inherent:

• strong and reliable design;
• high tightness of the installed product;
• the ability to rotate the double-glazed window around its axis for more comfortable washing;
• unpretentiousness in service;
• no need for periodic staining;
• long period of operation;
• variety of colors and sizes;
• acceptable cost.

As for the wooden windows for the attic, they are characterized by the following aspects:

• environmental safety and cleanliness;
• free air microcirculation;
• high aesthetic performance;
• higher pricing policy;
• the need for painting and more complex maintenance;
• the service life depends on the degree of care for the window block;
• the possibility of trouble-free repair during operation.

Types of windows depending on the method of opening

Depending on the type of sash opening used, the following types of roof windows are distinguished:

• rotary with an axis in the center - the most popular option, in which two-way scrolling of the sash is possible, which greatly simplifies the maintenance of the entire structure;
• mansard hatch - the opening of the sash passes along one of the side axes;
• raised axis - located in the upper section of the window frame, which allows you to open the sash up and down;
• lower axis - with this arrangement, the sash opens forward. A combined version is also possible, with the possibility of unfolding the sashes.

Types of windows by opening method

Please note: there are also electric windows on the market, the opening / closing of which is carried out using the remote control. Among other things, they are equipped with rain sensors that automatically close the sash when the first drops hit.

For lovers of comfort solutions

Choosing a place for mounting the unit

The choice of the correct location plays a significant role in subsequent operation, positively affecting the reliability of the window installed in the attic and its durability. Experts do not recommend installation in such places:

• along the slopes of the valley, as this will lead to the accumulation of precipitation around the window;
• in the immediate vicinity of chimney and ventilation systems, which is associated with the formation of condensate;
• near the border with horizontal walls, which can lead to the shading of the window in the attic and the accumulation of precipitation around it.

In general, window openings should not be located near any components of the roofing system.

In addition, when choosing a place, it is important to consider a number of the following factors:

• Type of roofing - rolled roofing can be cut without any problems in any place, which cannot be said, for example, about tiles. The window structure must be placed so that its upper line is higher than the row of the whole tile; if necessary, it is necessary to disassemble the section of the tile, subsequently laying the shaped or cut elements on the window frame.
• The rafter laying step - it is highly not recommended to violate the integrity of the rafter complex by selecting windows with the possibility of their installation between individual elements with a margin of 7-10 cm. Heat-insulating material will be laid in it. If necessary, it is better to install 2-3 small windows instead of one overall. If there is a need to partially remove the rafters, the window block should be supplemented with a horizontal beam to give the entire structure the required strength.
• The location of the handles on the window - they can be installed from above or below. In any case, they should have unhindered and free access without the slightest discomfort.
• The location of the heating - it is worth remembering to install the heater directly under the roof window. This will prevent condensation from forming.

Please note: when choosing the option with remote control, you should immediately take care of laying the cable to the mounted window unit.

Original performance with a small rafter pitch

Installation activities and their sequence

Installing windows in the attic is not a super complicated process and does not require special knowledge and specialized tools. Everything is quite possible to do on your own, it is only important to adhere to the correct sequence of actions and not to show excessive haste.

Preparing the opening for subsequent installation

Marking and preparatory work

The range of preparatory activities includes the following:

• the choice of the location of the future window - in this case, it is worth considering not only the features of the roof and the design of the window itself, but also the convenience of its subsequent use. In addition, the installation site must have good access to sunlight;
• analysis of the crate - the work is carried out from the inside, alternately cutting off the roofing cake in accordance with the markup;
• removal of roofing materials - we are talking about trimming the laid heat, sound and vapor barrier, for which a sharp knife or cutter is used. The freed edges of the coatings are fixed with nails with large caps or a construction stapler;
• dismantling the roof under the windows in the attic - you should be extremely careful not to damage nearby areas. The edges of the steel material must be coated with an anti-corrosion agent;
• reconciliation of dimensions - the final check of the conformity of the dimensions of the opening and the window block, followed by the installation of the frame.
• Please note: the slope of the frame must exactly correspond to the angle that the roof has, without the slightest discrepancy.

Features of installing a window frame

Installation of the window frame is carried out in the following order:

• fastening the frame in the opening - for this, the mounting screws or self-tapping screws included in the kit are used. Practice shows that a standard mounting kit is quite sufficient, but additional fixing strips can be used if necessary;
• installation of a double-glazed window - it is put in place and fixed with the help of special glazing beads;
• waterproofing - at this stage, the integrity of the broken waterproofing cake is restored, gluing all joints with a special insulating tape. Roofing material is fixed in the usual way for it;
• fixing the platbands - they put the platbands and slopes in place, giving the design of the roof window an aesthetic and complete look;
• opening adjustment - in accordance with the manufacturer's instructions, tighten the adjusting bolts for smooth operation of the mechanism.

Frame adjustment for hassle-free opening

Video: roof window installation

Until recently, the attic was associated only with a place to store old and unnecessary things. Today, in rooms under the roof, called attics, cozy living rooms, delicate bedrooms, and offices are equipped.

Purpose

The word "attic" comes from the name of the French architect of the 17th century, Francois Mansart, who was the first to decide to make a living space out of the attic. There were no holes for the penetration of light in such a room, darkness and closeness were constant companions of the person who lived there. It was only during World War II that the Danish engineer Villum Kann Rassmunsen proposed to make glazed openings in the roofs, allowing fresh air and natural light to enter the stuffy attic.

So, the main function of skylights is lighting. Experts believe that their correct choice and high-quality installation increases the amount of transmitted light by 40%. Due to the possibility of ventilation, air quality is significantly improved. The rooms are filled with comfort and mystery. If necessary, an opening in the roof makes it possible to get out of the house or, conversely, get inside.

Types and characteristics

The first skylights were glazed openings. The variety of models that exists today is the result of many years of development, the use of new technologies and the wishes of customers.

On the gables or in specially made external structures of the roof slope (the so-called "birdhouses"), vertical openings are made. They are easy to install, they decorate a cottage or cottage, but, however, they let in little light. Among the advantages are the absence of extreme loads acting on them and a variety of sizes.

The location of vertical windows in the lower part of the room prevents heat leakage. The "birdhouse" allows you to slightly increase the area of ​​\u200b\u200bthe upper room, but, on the other hand, complicates the rafter system and can lead to possible leaks at the points of attachment to the main roof.

Facade (cornice) windows are installed at an angle of 90 degrees directly under the roof. They allow you to make an exit to the terrace or balcony, enjoy a beautiful panoramic view, decorate the house with flowers. A small amount of natural light is the main disadvantage of these elements.

More common are inclined models installed in line with the ramp. It is believed that they let in up to 30% more light. The advantages are the optimal use of usable space and space savings.

One of the key differences between skylights is how they open. The most popular are mid-turn models. The only leaf opens by turning around its axis, located either in the center or 3/4 closer to the upper edge. Such models are easy to operate and maintain. However, full access to the outside can be difficult.

The choice of balcony-type windows is the desire to create a charming, beautiful mansion, unlike others. When folded, the design resembles a double sash, and when unfolded it looks like a small balcony. The top opens up and the bottom opens to the side. Balcony models can only be installed on a floor with a slope angle of 35-55 degrees.

Sometimes the architectural features of the roof do not allow the installation of full-size models. Then the hatch windows with a "light tunnel" would be an excellent solution. They are a tube, one end of which goes up, the other remains in the room.

Installing a "light tunnel" requires a large space between the attic ceiling and the roof.

Such hatches are also used in non-residential premises, but without a "light tunnel". The design consists of one sash, which rises to the top.

Swing models are another popular option for the attic. However, using them is not very convenient - in order to wash them, you must either stretch out a lot or go onto the slope.

The roof window can be equipped with a rain sensor and an electric drive. Remote control technology makes it possible to adjust the design without getting up from the sofa and even staying on the lower floor of the house. Wall switches can be used instead of remote control.

The choice of the type of window depends on the purpose of the room in which it is installed, the goals and aesthetic wishes of the residents. It is more expedient to determine how this architectural detail should look even at the time of construction - this will avoid unnecessary costs associated with the reconstruction of the slope. Installation of this product in a private house is quite possible to do it yourself.

It is important to decide which window options are right for you, for example, deaf, transformer, oblique or non-opening. Each of them has both its pros and cons.

Mounting Features

Skylights are located in such a way that external factors - wind, precipitation, snow and ice pressure, heat - have a strong influence on them. The process of their installation requires attention, knowledge and skill.

The most common mistakes during installation on metal tiles are incorrect installation of insulating salaries, poor insulation of slopes and the use of mounting foam. Anyway, Before starting installation work, read the installation instructions.

For a better understanding of the installation process, it is necessary to understand the structure of the window: a double-glazed window is inserted into the sash with an inert gas contained inside - argon, which provides excellent thermal insulation. The standard package includes aprons for waterproofing and vapor barrier, drainage gutter, flashing, thermal insulation material and internal slopes.

Before starting the installation work, it is necessary to prepare the tools: a tape measure, a building level, an electric drill and scissors for cutting metal, a hacksaw, electric scissors, a stapler, a screwdriver, pliers.

Installation is carried out on a beam laid below, or rafters. It is important to ensure that the gap on each side of the frame is at least 3 cm. The frame is installed at a height of 80 to 130 cm from the floor level. Several factors determine the height of the installation: the location of the handle, the type of roofing material, the structural features of the roof, the wishes of the customer. If the handle is at the bottom, the frame is placed higher, if at the top - lower.

The sheet covering can be cut in any part. If the surface is covered with ceramic tiles, it cannot be cut, and a hole can only be made over completed rows.

Marks are made on the waterproofing material where the holes will be located, the cut is made taking into account the margin - about 20 cm on each side. A waterproofing apron is placed on top of the waterproofing for complete tightness. Next, the roof covering is removed, the crate is cut, stepping back 2 centimeters from the support, and a beam is nailed from below - about 10 centimeters from the crate.

When performing work, it is imperative to use a level. The upper edge of the waterproofing is attached to the crate, and the lower edge to the beam. The side parts are pulled out to the outside.

Before installing the frame, it is necessary to remove the double-glazed window and the salary. Mounting brackets are placed on the box. It is important to remember that models from different manufacturers may have different shapes and be attached in different ways: only to the rafters or to the rafters and the crate. A heat-insulating material is attached to the upper part of the box, which is later pressed against the timber. Once the bottom edge is adjusted, tighten the bottom brackets firmly.

To improve waterproofing, a waterproofing apron is laid around the perimeter of the window opening. Usually it is included in the package, but you can make it yourself. Above the frame, a part of the crate is removed along the width of the drainage gutter. The gutter is carried out under the waterproofing material, cut in the middle, and installed along the perimeter of the frame. The top of the apron is pulled under the gutter, and its edges - under the crate. The apron itself is attached to the box with a stapler. The design ensures that moisture flows exactly into the gutter.

Upon completion of the laying of the waterproofing, the installation and fastening of the protective salary is carried out. Installation is carried out in the following sequence: below - a corrugated apron, then - the side parts and finally - the top element. In conclusion, put the lining to the auditory click. The lower apron is attached to the roofing material, and parts of the salary are attached to the grate and box. The sash is returned to the frame, the protective film is removed.

From the inside, it is recommended to install slopes - strips framing the frame. An opening stick must be present. Properly installed slopes (the upper one is parallel to the floor, and the lower one is vertical) help to carry out soft air circulation and natural heating. In addition, they perform an aesthetic function.

It is quite difficult to mount a triangular window, so it is better to entrust this work to a professional.

materials

Roof windows are made from various materials. Depending on preferences, possibilities and goals, you can choose wooden, plastic or metal products.

Wooden structures look great in country-style mansions and chalets, small houses and cottages. The main raw material is northern pine. The high density of glued wood makes the products flexible and allows the use of fewer fasteners. The great advantage of wood is the production of products of various shapes and sizes - arched elements, balconies.

Wooden products are subject to the negative effects of moisture, however, if you cover the frame with water varnish every 2-3 years, their service life will increase.

Wood is an ecological, natural, breathable material. It is much easier to breathe in a wooden house, which affects the level of living comfort.

Products made of plastic profiles, unlike wooden profiles, do not require special care. It is waterproof, does not rot and deteriorate under the influence of water and dirt, and can last 40-50 years. The issue of ventilation is solved with the help of special valves. Resistance to adverse environmental conditions, as well as low price, have made such products very popular. The problematic point is that when heated, a plastic profile can release vinyl chloride - a gas harmful to living organisms.

The plastic profile looks great in mansions, regardless of what they are built from. A special film makes it possible to adapt the color of the frame to the overall appearance of the building.

Sometimes roof windows are made on the basis of an aluminum profile. This material is resistant to corrosion and deformation, allows you to make products of various shapes and sizes. Aluminum products can be used for a long time (at least 80 years) in aggressive environmental conditions at a variety of temperatures. They are unpretentious in care, have protection from precipitation and ultraviolet rays. A wide choice of colors allows you to adapt the profile to any design of the roof and the house itself.

Products made of aluminum profile are cold and warm. Cold ones are used for glazing openings in non-residential premises. Warm structures are installed in the attics of residential buildings. Their profile consists of three parts with a thermal insulating insert. This structure prevents the penetration of cold air inside, and warm outside. The space between the thermostats is filled with polyurethane foam or extruded polystyrene.

On sale there are windows made of wood-aluminum profile. The outer side is made of aluminum, and the inner side is made of wood. Thus, external adverse conditions do not significantly affect the profile.

One of the requirements for structures installed under the roof is low weight. Often they consist of a 1-chamber double-glazed window with four types of glass: thermally polished (float glass), with a transparent metallized coating, tempered and triplex. Thermally polished glass prevents optical distortion. Glass with a metallized coating reflects ultraviolet rays.

When tempered glass cracks, many small particles with blunt edges are formed, which helps to avoid cuts. Triplex is a two-layer glass with a special film that holds the cracked fragments.

Reflective double-glazed windows, which help to keep cool in constantly lit rooms, are made to order.

There are also self-cleaning double-glazed windows - their outer surface is covered with a special agent that destroys organic pollution under the influence of the sun.

When choosing windows for the attic, it is necessary to pay attention not only to the material from which the frame is made. It is important to make sure that the fittings are of good quality - handles, hinges and others. It is preferable that the fittings used be original and made of stainless steel.

Dimensions

The choice of the size of the roof windows must be approached very carefully. Lighting, the appearance of the house, its perception will largely depend on this. Aesthetic preferences alone in determining the size are not enough. The area of ​​​​the room and the possible location of window openings should be taken into account.

In accordance with accepted standards, the window area should be at least 1 square meter per 10 square meters of the room. For the living room, studio and bedroom, the proportions may be different, for example, 1 to 8. Smaller proportions are possible for the toilet, bathroom, wardrobe, pantry and other utility rooms. However, the given proportions can be realized in different ways: in some cases, one large window can be installed to create a feeling of beauty and freedom, in others, several small ones will create coziness.

When designing an attic, it should be remembered that, according to experts, two or three window openings on opposite sides of the bevels will provide better lighting than one large one of the same area.

The gaps between the openings and their width depend on the distance between the rafters. Usually it is 80 cm, because the standard width of the roof windows is 78 cm. For a rafter system with a larger step, frames with a width of 94, 114 cm are used. If the distance between the rafters is small, you can purchase products with a width of 55 or 60 cm.

The high window allows you to enjoy the beautiful view. However, the choice of height depends not only on beauty. The main influence is the layout of the roof. On a flatter roof, a hole of greater length is made. For a roof with a slope of 35 degrees, the optimal length is 160 cm, for a roof with a slope of 70 degrees - no more than 120 cm. The length is also determined taking into account the fact that the lower edge of the structure should be at least 1 m from the floor.

So, the standard frame sizes are as follows: 78x118 cm, 78x140 cm, 78x160 cm, 94x140 cm, 114x118 cm, 114x140 cm. Non-standard glazing options are made to order.

Registration

Roof windows are an interesting architectural solution. Their design can be original, attractive, and an excessive amount of additional decorative elements, in turn, can harm the external and internal image of the house. Properly selected design gives a sense of organicity, romance, freedom, comfort, grace. But before choosing a design, you should figure out whether it is needed to provide protection from burglary, from the sun, or simply as a decorative element.

External shutters, so-called roller shutters, are usually used to protect mechanical damage and excessive sunlight; they provide sound insulation. It is better to install them outside, because being installed inside, they contribute to additional heating of the glass and the entire internal space of the attic.

External shutters, however, are not very beautiful and elegant and are more suitable for people who prefer functionality.

Another option for sun protection are thin nets, the so-called awnings. They allow light to pass through, scattering it and thereby reducing heat gain. Separately installed awnings also perform the function of a mosquito net.

Curtains are a classic way to decorate window openings. On vertical structures, ordinary curtains are used, on inclined structures - two cornices. The first cornice is installed on top, and the second is placed where it is convenient - it will not let the canvas fall and keep it in the desired position. Velcro, eyelets, braid, clips, tacks are used to fix the canvas. These elements are also used as decoration. Curtains bring elegance and tenderness to the visit.

Less original and aesthetic are blinds. However, they are easy to install and adapt to openings of various shapes, which makes them quite a popular attribute.

Pleated blinds are irreplaceable for non-standard forms of window openings. The canvas is held by a special cord or electric drive, which allows you to collect the curtain or hold it in the desired position.

In the interior, you can decorate windows exclusively to your liking. All decoration and finishing can be done independently.

The premises under the roof are increasingly being used as a living room. For reincarnation, it is enough to insulate the attic and install skylights. We will figure out which models are best to use, how to calculate their number, and describe the step-by-step technology for installing window systems.

Skylight requirements

Skylights are part of the roof structure, so their task is not limited to lighting. They must provide good thermal insulation, prevent precipitation from entering the room and withstand the negative effects of the environment.

Ordinary double-glazed windows are not suitable for arranging a roof, installation of special dormer-windows is required. The design must have the following characteristics:

• thermal efficiency - models with a thermal insulation coefficient of the order of 2-2.6 W / sq. m;
• noise absorption - high-quality products suppress up to 35 dB;
• strength - window panels must withstand direct impacts of hail, snow deposits, so they are covered with a special film or made of tempered glass;
• exceptional tightness - sealing pads are provided in the design.

Skylights should be easy to open, have roller shutters for shading, and be easy to clean.

Types and characteristics

When choosing a roof window, pay attention to the type of construction, the method of opening the sashes and the frame material.

Variety by type of construction

Depending on the placement on the roof and the design idea, the following types are distinguished:

• inclined systems;
• "cuckoos";
• balcony;
• light tunnel;
• extensions.

Inclined. Standard systems mounted on roof slopes. Such windows provide excellent illumination, they are easy to install and practical to use. A variation of this type is inclined systems with a lower insert. The top of the structure opens, and the bottom profile is deaf. In this case, one part can be placed at an angle, and the second - vertically.

"Cuckoos" or "birdhouses". Vertical type windows are installed in remote structures, on slopes or in gables. "Cuckoos" look original, but have some disadvantages: poor lighting, laborious installation, difficult snowmelt.

Balcony. Combination of sloped and vertical glazing. The lower part of the attic window acts as a balcony parapet.

light tunnel. An original solution for small attics, if an attic is still placed on top. A reflective tunnel conducts light - ceiling lamps are installed at the exits.

Extensions. Compact inserts of various shapes: semi-circular, round, triangular window. As a rule, they are used as an addition and decoration of the attic room.

Types by opening method

According to the opening mechanism, the following types of windows are distinguished:

1. central axis. The opening mechanism is located in the middle of the sash, which makes it possible to deploy the window in both directions. The most popular model, practical in operation. A variation of the system is a variant with a raised axle.
2. combined mechanism. The design combines the central and upper opening axes. The first one provides double-sided opening, and due to the second one, it is possible to set the window to the ventilation mode (the maximum opening angle is 45 °).
3. side axis. A simple option - the attic hatch swings open only in one direction.
4. Remote control. Semi-automatic system controlled by remote control. It is irreplaceable at a high arrangement of a window.

Expensive models are equipped with rain and smoke sensors. If drops of water fall on the outer glass, the window closes automatically. The same effect occurs when the room is smoky - the sash swings open for ventilation.

Material classification

Roof window frames are made of PVC, aluminum or wood. For "dry" rooms, any options are suitable, and when arranging a bathroom, it is better to abandon wood. Universal type - metal-plastic profiles.

Features of different types:

1. Wooden: environmental friendliness, attractiveness, creation of an optimal microclimate. Minus - susceptible to moisture, require treatment with antiseptic compounds.
2. Plastic: practicality, affordability, weather resistance. Minus - absolute tightness blocks natural ventilation.
3. Metal: high strength characteristics. Minus - high cost.

Roof window device

Due to the special operating conditions, roof windows have a more complex structure than conventional wall models. The delivery set, in addition to the traditional double-glazed window, frame and fittings, includes additional elements:

• insulating protective salary - is responsible for sealing the gap between the roofing and the window frame; the profile of the lower part is selected taking into account the relief of the roof surface;
• waterproofing seal; salary redirects moisture to the drain;
• drainage gutter for protection against leaks;
• warming insert;
• internal slopes.

Some models have built-in blinds or a lifting curtain.

Determination of the glazing area

The dimensions of the roof windows directly depend on the dimensions of the room. There is a rule: in a living room, the total size of windows should be at least 10% of its area.

Important! For living rooms and children's rooms, it is better to increase this figure to 15-20%.

For example, for an attic area of ​​​​20 square meters. m fit two window systems 115 * 120 cm or three windows with dimensions of 80 * 140 cm.

When calculating, you need to take into account some nuances:

• the higher it is located, the more light it transmits;
• high placement is appropriate on sloping roofs, the angle of inclination of which is no more than 15-20 °;
• on steep slopes, the bottom line of the profile should be at a height of 1-1.4 m;
• the lower limit for other types of roofs is 0.8 m, the upper limit is 1.9 m.

Where is the best place to mount a window

The installation location of skylights largely determines the aesthetics of the exterior, the durability of the entire roof and interior decoration. It is highly undesirable to equip the opening:

• on the walls of the valley - precipitation may accumulate in the inner corners;
• near chimneys, ventilation ducts, which can provoke the formation of condensate;
• near the junctions to the walls - shading and accumulation of precipitation are likely.

Experts advise avoiding the proximity of any nodes of the roofing system to each other.

When choosing a place, the following parameters are taken into account:

1. Roof type. Soft roll material can be cut anywhere. When installing on tiles, it is necessary that the lower window line borders on the “solid” row of roofing.
2. Rafter step. Optimal - the location of the window structure between two adjacent rafters, the margin for laying insulation - 7-10 cm. If there is not enough space, then it is better to install two or three small models instead of one window.
3. Handle location. Window systems with a top handle are mounted at a height within 1.10 cm. If the handle is built in from below, then the frame can be raised up to 1.7 m.
4. When arranging a mechanism with a remote control, you should take care of the cable connection.

Under the glazed structure it is necessary to place a heating radiator- this will save the windows from the formation of condensate in the winter.

Attic window installation technology

It is better to mount the window system at the stage of roof construction. Make a skylight do it yourself it is possible during the operation of housing, but you will have to cut an opening.

Preparatory activities

You need to stock up on tools in advance. For work you will need:

• level;
• roulette;
• plumb;
• ruler;
• mallet and hammer;
• screwdriver

Cutting the wooden elements of the roof is carried out with an ordinary saw, to dismantle the profiled sheet or slate, use a grinder with different nozzles.

First you need to study the roof scheme, understand the location of the rafters and markup - mark the borders of future windows taking into account clearances for structural elements.

Cutting a window opening

The first step in the installation of roof windows is the creation of an opening in the roof. The work is painstaking and responsible, without the appropriate skills there is a risk of damaging the roof structure.

Procedure:

1. Check that the size of the windows matches the markup. On each side there should be allowances of 3 cm for laying insulation.
2. The technical gap from the bottom of the window system to the roof covering is about 8 cm. 4-10 cm are left from the upper mounting beam to the roofing material - to prevent the window from skewing when the truss structure shrinks.
3. Remove the lining according to the markup. Cut the crate and the heat-insulating layer - the cut is performed parallel to the floor at the top, and vertically at the bottom. This approach will open unhindered access to light.
4. Remove the tile, cut the profiled sheet.

Window box arrangement

Before you install a salary and a double-glazed window, you need to take care of a reliable support - its role is played by the box.

Work progress:

1. From below, mount a temporary support - any wooden block. Check the lower horizontal of the window, distortions are unacceptable.
2. Fix the bottom of the box with screws, then fix the upper part of the frame. In the future, adjustment may be necessary, so the fasteners do not need to be tightened tightly.
3. Check the evenness of the frame placement - evaluate the horizontal / vertical. You can adjust the position using plastic wedges.
4. Mount thermal insulation - lay the insulation in the gaps between the frame and the roof pie. Cut material with a small margin.

Installation of a salary and a double-glazed window

To prevent leaks, a window frame is mounted - a protective apron is supplied. Sealing element installation sequence:

1. Fix the lower part of the salary with a protruding rubber visor.
2. Fix the top cover by attaching it to the screws.
3. Mount the side sections all the way down. Using clamps, attach the salary to the crate.
4. Bring the roofing material to the seam on the protective apron.
5. Lastly, plastic lining is installed on top of the salary.

The final stage of installation is the insertion of a finished double-glazed window. It is better to do the work with a partner, so that one holds the sash, and the second carefully mounts the window into the prepared opening. The set must match the salary.

First, fix the bottom of the window by screwing the brackets all the way. The top fasteners are left in a slightly free position - this is necessary for adjustment. After checking the evenness, all brackets are finally fixed.

Installation of windows on the pediment of the attic is carried out according to the traditional scheme. It is permissible to use conventional window systems here - the vertical position protects the glass from direct precipitation.

The best roof window manufacturers

Window systems from the following manufacturers have won a good reputation among users:

1. Velux. The Danish company specializes in the production of wooden windows. High quality wood, antiseptic impregnation and multi-layer varnish ensure the durability of the systems. All products are equipped with ventilation valves, two- and three-level seals. The windows performed well in various operating conditions.
2. Roto. German quality of plastic window systems. Roto products are unrivaled for the design of wet attic spaces. The profiles are resistant to moisture, the frames do not lose their original appearance, they do not need to be tinted and periodically treated with antiseptics.
3. fakro. The Polish company produces windows from different materials, respectively, and the pricing policy is very diverse. The profiles are supplied in standard sizes, so the architecture of the existing house must be taken into account.

The issue of making do-it-yourself roof window systems must be approached carefully. To perform high-quality installation and maintain the reliability of the roof, all technological requirements must be observed. An important point is the competent calculation and choice of the location of the windows.
