Installation of the roller blind can be done into the ceiling or on the window lintel. Lately there is a trend and demand for installation into the ceiling drain, so called 15 x 15cm space in the ceiling. Linens, which are used, can be regular half-transparent, screen or darkening, which are also divided into external and interior. The roller blind is suitable for public spaces, where carefully selected and quality material with robust look of the shade ensures long service life.

Exterior use

In case of exterior use of the shade, you need to ensure suitable leading of the linen, because of the wind, which is done with 5mm stainless steel braided cable and ends, where tightening of the braided cable is done. When we want to use thermal and darkening linen as a shade, the double roller blind V enables us installation of both shades onto one console, which are normally installed into the 20 x 20cm cartridge into the ceiling. Control can be manual or with a motor.
