Screen are a modern covering product, mounted on the outside of the window, similar to classic external roller blinds or external venetian blinds. The screen is primarily a protection and a barrier against excessive sunlight, as well as heating of windows and rooms in the building. The use of screen roller shutters allows the reflection of solar energy up to 95%, and thus allows you to save on the use of artificial lighting and the costs of cooling the building (up to 58%). The blinds of this type have a ZIP zipper system that guarantees perfect fabric tension, thanks to which the blind is very stable, windproof, and protects against insects when closed.
