OKASOLAR F

Optimized Daylight System for the Façade

OKASOLAR F is a daylight system optimized for facades and unites the use of daylight with effective sun protection. The louvre type OKASOLAR F U reflects a large part of the solar irradiation to the outside. OKASOLAR F O is also retro-reflective and directs the incidental daylight deeply into the room. By combining both louvre types in one element, the requirements of the interior can be dealt with specifically.

OKASOLAR F can significantly lower the cost for artificial illumination and cooling loads and optimize the energy balance of a building. Due to the extremely narrow profile cross-section of the louvres, OKASOLAR F is especially well-suited for triple-insulating glazing and narrow pane build-ups.
