Today, the designs of roof windows are distinguished by their originality. These can be inclined, cornice openings in the roof, structures that transform into a balcony, extensions and additional decorative elements. But after installing the windows, the question immediately arises: how to protect the room from the flow of light that penetrates into the home in excess in the summer? After all, the non-standard shape of the openings and the inclined location complicate the task. The most rational solution is to install special roller blinds on the roof windows.

How did dormer windows appear?
The architect Francois Mansart was the first to suggest using the space under the roof to create a living room in the 18th century. The design of the rooms turned out to be unusual. The idea was liked by Europeans for its originality and the ability to use attic spaces. But the simple and ingenious idea had one significant drawback – lack of light. The problem was solved in the 20th century by the Danish engineer Willum Kann Rasmussen. He created slanted dormer windows.
Types and features
Dormer windows are located at the highest level of the house. They serve to illuminate the room directly under the roof. Therefore, their main feature is the slope and unusual shapes. The design can be different:
- Beveled. The most common type of attic "skylight". Mounted vertically into the roof. Due to the angular slopes of the roof, the opening is beveled.
- Cornice or facade. A regular standard rectangular window, but installed in a wall under the roof.
- Balcony. When opening the floor-length glass sections, you get something like an exit to a loggia. Some versions have terraces that you can easily access.
- Panoramic. They occupy a large area of the roof slope. They let in a lot of light, making the room more spacious.
Shading methods
Shading of the attic space is a very relevant issue. After all, in summer, without sun protection, the area under the roof heats up twice as fast. Attic openings have their own specifics - an oblique slope line and non-standard configurations. Therefore, only certain types of sun protection devices are suitable for them. According to the type of installation, they are divided into the following types:
- Internal. Installed indoors.
- External. Protect from light from the outside.
The following are internal light filtration devices:
- Roller shutters with side guides.
- Pleated blinds.
- Black-Out fabric panels.
- Blinds made of aluminum and plastic.
Roller shutters with side guides
Roller blinds are fixed on the sides with the help of guides. This eliminates sagging of the canvas, which is important for inclined structures. If the roller blinds are at a height, they must be equipped with a remote-controlled mechanism.
Pros
- Simplicity of design.
- Easy installation.
- Reliable protection from light.
- Low price.
- A huge selection of models in color and texture.
- Good fixation on inclined surfaces due to side guides.
- Many mounting options – on the wall and ceiling, inside the opening, on each leaf.
Cons
- The design is not particularly durable. It will have to be used with extreme care.
- Some models are attached with special tape. At high temperatures the glue may melt.
Pleated blinds
Externally, they look like regular blinds. But they do not consist of lamella strips, but of fabric (polyester), which folds "into an accordion" when raised. "Pleated" blinds are made in different sizes and colors. Such sun protection devices are used, among other things, to darken rooms under the roof.
Pros
- Suitable for any, even the most non-standard, configurations.
- Space saving. Pleated blinds can be installed on each sash. The window sill area will remain free.
- The convenient control system allows you to mount light protection on surfaces located at an angle.
- Durability. The pleated material is impregnated with a composition that repels dust and keeps the shape of the canvas for a long time.
Cons
- Complex care. The canvas needs constant care – wash only by hand (at 30⁰). For cosmetic care, it is enough to wipe the surface with a soft sponge.
- High cost due to complex production process.
Black-Out Fabric Panels
Made of opaque fabric and absorb light by 80-90%. Allows you to almost completely shade the room, justifying its name (from English "black-out" darkening). A relevant option if you plan to convert the attic area into a bedroom.
Pros
- Excellent light protection. The dense texture allows you to create pitch darkness even on the brightest day.
- Sound absorption capacity (coefficient – 30).
- Easy to care for. Black-out roller blind fabric is easy to wash and does not require ironing.
- The fabric repels dust and is resistant to fading and mechanical damage.
- Often fabric roller blinds are impregnated with a fire-resistant compound.
- High aesthetic qualities.
- Wide choice of design. Any picture or photo can be applied to the roller blinds. This gives the opportunity to create an original interior according to your own design.
Cons
- Expensive. Black-out panels undergo many stages of processing during production. Therefore, such "curtains" are not cheap.
Blinds
They are made of thin aluminum, plastic, bamboo, a new model is isolight. The slats do not obscure the panorama, but at the same time protect the rooms from sunlight. They allow you to regulate the flow of light entering the room. For inclined openings, blinds with guides made of steel strings, masked on top with plastic or aluminum, are best suited.
Pros
- Light adjustment. The slats can be turned at a certain angle. This allows more or less light to enter the room. By tightly closing the structure, you can isolate the room from prying eyes.
- Compatibility. Blinds are easily combined in the interior with tulle and curtains.
- Easy to maintain. Just wipe the surface with a soft sponge from time to time.
- Possibility of repair. A broken lamella can be easily replaced with a new one.
- Affordable price.
Cons
- The slats often make sounds during ventilation or when exposed to a draft.
- In some cases, repair of individual slats is not possible.
External light protection devices include:
- marquisette;
- roller shutters.
Marquisette
Externally similar to a fabric roller blind, but is installed on the outside. The canvas is made of fine polymer mesh. Such mesh material is capable of holding back light by 60%. At the same time, awnings do not allow the glass to overheat, effectively protecting from heat. Installed on models with a rotary or rotary-tilt design. The degree of opening/closing of the awning is easily adjusted and fixed with special hooks.
Pros
- Provides good protection from light streams without obscuring visibility.
- Protects against glass overheating. Thanks to the awnings in the attic room, the temperature can be reduced to 5⁰ in summer.
- Possibility of automatic control using solar panels. In this case, the remote mechanism does not need to be wired to the attic.
- Allows air to flow without raising the roller shutters. The awning is firmly fixed to the frame, so the transom can be opened at any angle.
Cons
- Do not provide complete darkening.
Roller shutters
They look like blinds. Roller shutters are also made of steel or aluminum slats. But the operating principle is slightly different. Roller shutters are raised on a shaft that rotates to roll up the canvas.
Pros
- Provides reliable protection from sunlight.
- Provides absolute blackout.
- They protect from heat in summer. In winter, they reduce heat loss by about 20%.
- They perform a security function. They can protect against burglary.
Cons
- High price.
- Complexity of installation.
Roller blinds are the perfect choice for shading the attic
Today, more and more people prefer large panoramic glazing. And if such a structure appears on the roof, the design will be ultra-modern. But one problem arises. It will be quite difficult to shade such huge glass inserts. Roller blinds with side guides for panoramic windows are considered the best means of protection from the sun today for a number of reasons: they are easy to select according to the size of giant openings, they are easy to operate and are tightly fastened.
This simple and convenient device is a piece of fabric that is rolled onto a shaft using a special mechanism. The design has another name – a fabric roller blind. When folded, it looks like a roll. Roller blinds look more presentable than blinds. They are more practical than regular fabric curtains. And most importantly, they allow you to firmly fix the fabric, which prevents it from sagging on an inclined surface.
There are several options for roller blinds material:
- Black-out – creates complete darkening of the room due to special weaving or special impregnation.
- Screen – allows you to remain invisible from the outside, but external panoramas are clearly visible from the inside.
They are mounted in several ways:
- On the frame.
- Inside the opening.
- Above the opening.
Important. For large segments, roller shutters with a reinforced bottom bar are selected. It should firmly hold the canvas from below.
Each segment can be equipped with a separate roller blind. They can be controlled separately or centrally.
