With a wide range of louver blades, the movable Schüco louver blades ALB with linear drive provide compelling benefits including increased comfort, optimized natural light incidence and protection against overheating and the active energy generation by built-in photovoltaic modules. The integration of the drive into the lamella cover and concealed drainage in the louvers set new standards. The bracket system allows considerable design freedom and strain-free mounting of all glass louvers.
