The first screen roller blind coming up directly from the development department of company ISOTRA. Depending on the chosen type of the fabric, the screen blind ALFA provides a maximal protection against sunshine, heat penetration, as well as it ensures the optimal level of natural light in an interior. Thanks to this partial light permeability and variability, it shadows a room, but still allows the view out, though complicates the view from exterior inside and thereby protects the privacy. It is possible to choose also the blackout fabric that provides the complete obscuration.
ZIP system is unique thanks to the hidden stainless spring in the guiding rail. The spring does not wear down, so the fabric keeps its tension for many years. The roller screen blind ALFA offers a practical insect protection, while the space between the box, guiding rails and fabric is completely sealed. It is possible to shadow up to 18 m2 with one piece of this roller blind, that has wind resistance class 6.
Thanks to the profile with an integrated guide rail, these screen blinds can also be combined with ARTOSI SLIDE PANELS.
