OKASOLAR W

Outstanding Daylight System for the Façade

OKASOLAR W is a high-performance daylight system especially developed for the facade which combines the use of daylight with effective sun protection. Fixed louvres in the cavities direct daylight deeply into the room while ensuring excellent direction-selective sun and glare-protection. A further advantage of OKASOLAR W: the cooling loads and costs for artificial illumination can be significantly reduced and the energy balance of a building optimized.
