What is exterior window shading?
External sun blinds for your windows stop solar heat before it reaches the glass. This is often more effective than internal sun blinds, as the heat remains outside. Think of screens, drop arm awnings, roller shutters or marquisolettes. STERK assesses your window, facade and desired aesthetic, and advises on the most suitable external sun blinds.

Frequently asked questions about external window coverings
Why blinds on the outside of the window?
External sun blinds block heat before the glass warms up. As a result, they are often more effective against heat than internal sun blinds. They are a smart choice for living rooms, bedrooms, and workspaces where the sun shines on the window for extended periods.
What types of sun blinds can be installed on the outside of windows?
This depends on the window, facade, and desired look. Consider screens, drop-arm awnings, or other exterior solutions. If you want to explore a wider range of exterior solutions, exterior sun protection is a good fit.
Is external sun blinds suitable for privacy?
Yes, some types of external sun blinds also reduce visibility from the outside, especially during the day. At the same time, you often still maintain a view to the outside, depending on the fabric and system. We will bring samples so you can see the effect on light, privacy, and appearance.
Can exterior blinds be electric?
Yes, many exterior sun blinds can be operated electrically. This is convenient for high windows, multiple screens, or daily use. Also, check out the possibilities for electric sun blinds.
Can external sun blinds be fitted on plastic window frames?
Often, yes, but we carefully consider the installation. Sometimes we prefer to mount on the facade or in the reveal rather than directly on the frame. You can read more about this at sun protection for plastic frames.
How much does exterior window shading cost?
The price depends on the type of sun blinds, window size, operation, installation, and fabric. A small bedroom window is different from a wide glass facade. STERK measures and provides a clear quote, so you know exactly what you're getting.
Is exterior sun protection resistant to wind?
That varies per system. Some solutions are more wind-resistant than others, but no sunshade should remain unnecessarily open during extreme weather. We advise based on your facade, location, and use, for instance, in open locations or on higher floors.
Can STERK provide multiple windows with exterior sun blinds simultaneously?
Yes. We can include multiple windows in an advice, taking into account size, color, symmetry, and operation. This creates a more harmonious facade and prevents each window solution from being chosen independently of the others.
