Exterior window sun screens
Starting from
€25
Exterior sun screens are the most effective way to keep heat out. Because sunlight is blocked before it reaches the glass, the window barely heats up and your home stays noticeably cooler.
Keep the heat outside without high costs. Our exterior sun screens with suction cups block up to 97% of heat when installed outside, making them an affordable alternative to air conditioning or electric shading systems.
No expensive installation or permanent mounting: you can easily install the screens yourself without drilling or screws. They are custom-made for any flat window and available starting from €25 per screen.
A smart, effective and sustainable in one solution.
Our exterior sun screens are fully custom-made and suitable for any flat window. Whether you have a large south-facing window, want to reduce the temperature in your bedroom or children's room, minimize glare in your home office, or keep your attic cooler, exterior sun screens provide an effective solution.
Especially large glass surfaces such as skylights or glass doors can quickly cause indoor temperatures to rise. Thanks to the strong vacuum suction cups, the screens attach securely to your window, even on larger surfaces. That way, you’ll prevent excessive indoor heat without permanent installation.
Do you have a window with a special shape such as round, triangular or trapezoid glass? We also make custom sun screens for those. Our screens are precisely tailored to the shape of the glass, allowing you to enjoy effective exterior shading even with unique windows.
Where standard sun shading stops, we go further.
Traditional exterior sun shading quickly costs hundreds to thousands of euros. At Sun Eclipse you can order custom sun screens starting from just €25. This allows us offer the lowest price per m², without compromising on quality.
Exterior sun screens can block up to 97% of heat before it reaches the glass, making them a powerful alternative to air conditioning or other expensive solutions.
Already using an air conditioner? Then it won’t need to work as hard, which makes cooling more energy-efficient and cost-effective while keeping your home comfortable.
At Sun Eclipse you choose how your sun screens look and perform. You can choose between screens that maintain visibility and screens designed for maximum heat blocking. Both types are available in multiple colors and suitable for exterior window installation.
Choose the colour that best matches your window frame. We supply matching caps in the same colour as your screen. All colours are suitable for outdoor use.

You attach the screens directly to the glass using strong vacuum suction cups. Within minutes, your exterior sun screen is securely installed.
Installation in short:
Removing the screens is just as easy. Store the sun screens clean and dry so they can easily be reinstalled next spring.
Thanks to the special coating, dirt hardly adheres to the screen, meaning you typically only need to clean it once per year. Both the screen fabric and the vacuum suction cups are UV-resistant and hardly discolour over time.
After the season, simply remove the screens and store them clean and dry. For cleaning, use the Sun Eclipse cleaner and a soft cloth.

The best indoor sun protection is a solution that blocks sunlight as close to the window as possible. Curtains are often positioned too far away from the glass, causing heat to build up between the curtain and the window. Window film, on the other hand, is attached directly to the glass, which causes the glass itself to heat up and release heat indoors, with a risk of thermal cracks.
Sun protection with suction cups is an ideal alternative for indoor installation. The screen is attached directly to the glass using vacuum suction cups, while still hanging approximately 2 cm away from the window. This blocks sunlight before it enters the room, without heating up the glass itself. This system is especially suitable for apartments where windows cannot be opened, rental properties, and listed buildings, as no drilling is required.
For indoor installation, a light-coloured screen (such as White or Boulder) is recommended. Light colours reflect sunlight, preventing the screen itself from heating up. Choose Optimal View if you want to maintain visibility to the outside from your living room, or Maximum Sunblock for bedrooms where maximum heat reduction is more important than visibility.
A major advantage: you can measure everything yourself, no installer is required, and delivery only takes 3 to 5 working days. In addition, sun protection with suction cups is affordable from just €25 and is 10 to 15 times cheaper than an electric screen.
Sun protection mounted on the outside of the window blocks the most heat. The reason is simple: the screen captures sunlight and releases the heat outdoors before it reaches the glass. This is the most effective principle for heat reduction.
The screen type Maximum Sunblock offers the highest heat reduction: up to 97% when a dark screen (such as Anthracite or Black) is mounted on the outside. Dark screens absorb heat and release it outdoors, similar to a black T-shirt in the sun. Because the screen hangs approximately 2 cm away from the glass, the heat does not transfer directly onto the window.
For slanted windows, roof windows and skylights, we always recommend Maximum Sunblock with a white screen. These types of windows are often exposed to direct sunlight, and due to the angle, the screen always rests against the glass.
Dark screens absorb more heat and transfer this heat back onto the glass. This can cause the glass to heat up further, which may lead to stress or, in exceptional cases, cracks.
A white screen reflects most of the sun’s heat and transfers far less heat onto the glass. That is why a white screen is mandatory for slanted windows.
For comparison: curtains block significantly less heat because they hang further away from the window. They absorb part of the heat and then release it into the room. Window film heats up the glass itself. Sun protection with suction cups combines the best of both worlds: it is positioned close to the window without causing the glass itself to overheat.
Yes, screens can also be mounted on the inside of the window. Although exterior installation is the most effective option, interior installation provides an excellent solution when mounting outside is not possible. For example, in apartments with non-opening windows, rental homes where changes to the exterior façade are not allowed, or listed buildings.
With interior installation, the screen still blocks sunlight before it can deeply enter the room. The screen is positioned approximately 2 cm away from the glass, meaning sunlight is already stopped close to the window.
The difference compared to exterior installation is that the absorbed heat is released indoors instead of outdoors. Because a light-coloured screen reflects most of the sun’s heat, the screen itself barely heats up. As a result, the effect remains significantly greater than with curtains or window film.
Sun protection with suction cups is especially suitable for interior installation. The vacuum suction cups are attached directly to the glass, so no drilling is required. However, the glass surface must be completely flat; the system does not work on textured glass, patterned glass or stained glass windows. The screen is suitable for virtually any window size, including unusual shapes such as triangles, round windows and trapezoid windows.
Heat-blocking and blackout are two different functions of window coverings. Heat-blocking products are primarily designed to keep heat outside. They reflect or absorb sunlight to keep the room cool, while often still allowing some light through so you can maintain your view outside. Blackout products are designed to fully block light, for example in bedrooms, but do not necessarily reduce heat.
A heat-blocking screen such as Optimal View allows you to look outside while blocking a large portion of the heat. This makes it ideal for living rooms where you want to enjoy daylight without overheating. The screen type Maximum Sunblock combines both functions: it blocks up to 97% of the heat and provides a strong blackout effect, making it highly suitable for bedrooms. With a white Maximum Sunblock screen, visibility is more limited, but you can still partially look outside.
In short: if you want a cool and dark bedroom, choose Maximum Sunblock. If your priority is heat reduction while maintaining your outside view in the living room, Optimal View is the best choice.
Yes, Sun Eclipse screens fit all shapes of flat glass. Please refer to the measuring instructions during the ordering process for non-standard windows.
Yes, this is possible!
Sun Eclipse screens are 2 cm from the window’s surface so that the window will not heat up when the screens are mounted in front of the window. This is in contrast to e.g. a film that is attached to the window itself. However, there are some guidelines that must be followed with HR+++ windows.
