Solar control films for windows ☀️ Free cut to size

Sun protection film for windows with noticeable heat protection lowers the room temperature by up to 12°C.

Our high-quality sun protection films for indoor and outdoor installation provide you with noticeable protection from the sun's heat & glare at the window. The heat protection films effectively lower the room temperature thanks to 50 - 89 % energy rejection (depending on the film type). Rooms heat up less, air conditioning systems are relieved and the feeling of well-being within your own four walls increases in summer.

Should sun protection film be installed inside or outside?

Compared to interior films, exterior films have the advantage that a large part of the sun's rays is directly reflected. A smaller part is absorbed and only the smallest part passes through the pane. In addition, they can be used as heat protection on almost all insulating glazing.

It is advisable to apply the film only to the outside of modern insulating glazing installed after 1995 and the heat protection film for roof windows described below. The reason for this is that the tension in the glass is too high, which could occur if the film is installed on the inside.
We therefore generally recommend that you only apply the self-adhesive heat protection film to the outside of sloped glazing, such as conservatories or skylights! This is because the solar radiation is extreme due to the installation position being inclined to the sun. By installing the film on the outside, the window glass remains significantly cooler and the thermal loads on the windows are lower. This installation is even possible with solar control glazing. In addition, the protection value is approximately 4% higher with external installation.

The situation is different with vertically installed window panes: Here, depending on the type of glass installed, interior installation is possible. The sun protection for windows on the inside is often used if your windows cannot be opened or there is no possibility to install it from the outside. The heat protection on insulating glazing is more durable when installed indoors, due to the fact that it is not affected by weather conditions such as wind or rain.

Sun protection films for roof windows

Especially in attic flats, temperatures often rise immeasurably in the summer. The sunlight coming in through the skylights heats up the rooms considerably. Once the room temperature is at the same level as the outside temperature, ventilation rarely brings any significant improvement. This is exactly where our sun protection films for roof windows promise effective relief by reflecting the sun's rays back onto the outside of the window glass. With the help of the heat protection film, the heat does not even penetrate through your double glazing, which leads to a significantly cooler room temperature (depending on the design). For bedrooms under the roof, for example, we recommend the silver dark mirrored sun protection film with the strongest protective value.

Further advantages of sun protection films in a nutshell:

• No maintenance required regardless of the weather
• Depending on the type of film, the film also has glare protection, which makes working at computer workstations much more pleasant
• Reduction of the temperature in the room and cost reduction for air-conditioning, air-conditioning units are relieved of load
• Complies with workplace regulations §9 paragraph 2 and §6 paragraph 1
• Scratch-resistant surface, easy cleaning with commercially available glass cleaners
• More pleasant room temperatures in summer thanks to effective heat protection. This can be easily determined with a product test: Using an infrared thermometer, the temperature difference can be determined directly, even with our samples.
• Depending on the type of film, solar control film protects against heat reduction in winter periods (particularly effective with single glazing)
• Clear view without distortion to the outside (only self-adhesive heat protection films)
• Daytime privacy thanks to the mirror effect, depending on the film type
• Depending on the film type, also suitable as UV protection film, safety film / shatter protection film or anti-glare film

Sun protection film for shop windows

The special characteristics of a shop window require special sun protection. There are two alternatives for this application:

1. You use a completely transparent UV protection film, which protects your displays from fading. This does not provide any heat protection and therefore does not end-load your air-conditioning unit, but it effectively slows down the fading of the objects behind the window by a factor of 3-4.
2. If you want additional heat protection for your shop window, then choose our clear transparent sun protection film or the slightly silver mirrored heat protection film, which allows passers-by to continue looking through the shop window. For very large shop windows, we can also supply the film as a whole roll.

Most shop windows consist of single glazing, so there is nothing to prevent the interior installation of a film with light heat protection.

Privacy protection thanks to mirror effect

With all highly mirrored sun protection films, the reflection caused by daylight during the day is sufficient to create a visual screen and prevent passers-by from looking through the window pane from the outside. We refer to this type of film as mirror film and have compiled a list of all possible sun protection films with mirror effect in this category.
The advantage of this type of film is that it prevents people from looking in, just like a privacy film. Due to the high reflection of the sun's rays, there is also a certain light protection. However, unlike a frosted glass film, for example, the privacy protection is only on one side. The disadvantage is that the privacy screen only works during the day. In the evening, when it gets dark, there is no reflection.

Cut to size

We cut all window films precisely to your desired size. The cutting is done with millimetre precision thanks to the latest computer technology, starting from a large roll of film. On each article page, the dimensions can be entered in centimetres [ cm ] with decimal places. In addition, there is a large selection of geometries to choose from. This means that the window film fits directly onto the glass and does not have to be laboriously cut to size on site. The delivery of individually tailored films with heat protection takes place within a few working days thanks to our shipping partners.
As an alternative to computer-controlled cutting, we also offer the films as running metres or whole film rolls for large purchase quantities.
