What are blackout screens?
Dim-out screens are screens with a fabric that blocks more light than a standard screen fabric. They are ideal for bedrooms, studies, TV rooms, and windows where you want less bright light. The exact effect depends on the fabric type, color, and gap sealing. STERK uses samples to show what suits your wishes for comfort, privacy, and light incidence.

Frequently asked questions about blackout screens
When do you choose blackout screens?
You choose blackout screens when you want less light than with standard screens. Think of bedrooms, children's rooms, studies or rooms with a TV screen. We discuss beforehand how much blackout you expect, so you don't make the wrong choice based on just a colour or product name.
Are blackout screens the same as screens?
They fall under screens, but use a fabric that blocks more light. If you first want to examine the basics of sun protection, then screen sun protection is a good fit. The difference mainly lies in the fabric choice and desired light incidence.
Can blackout screens also be zipper screens?
Yes, often. By combining a denser fabric with zip screens, the fabric remains taut in the side guides and light is better restricted along the edges. This can be particularly pleasant for bedrooms or large windows.
Can blackout screens be electric or solar-powered?
Yes. With electric outdoor screens you can easily operate them from inside the room. If wiring is difficult, solar screens may be suitable. We always check if the chosen control system matches your window and usage.
Do you install your blackout screens outside the window?
Most of the time, yes. Exterior placement helps to limit heat and light before the glass heats up. For specific windows, we look at a neat screen window. In a broader sense, this is also a form of exterior screen sun blinds.
Are blackout screens suitable for a canopy?
That's possible, but it depends on the purpose. For a canopy, you sometimes mainly want privacy or less low-hanging sun. In that case, canopy screens with a denser fabric might be interesting. We pay extra attention to wind and mounting in such cases.
Can I just have the canvas replaced?
Yes, if the system is still in good condition, new screen fabrics can be a suitable solution. You can then choose a fabric that blocks more light or better matches the facade. We first assess the cassette, guides, and operation.
Are blackout screens affordable?
The price depends on size, fabric, operation, and installation. A denser fabric or electric operation can affect the price. If you are looking for a sharp basic, compare with cheap screens. STERK honestly advises what is necessary and what is not.
