OKASOLAR S

Outstanding Sun Protection for Roof Glazing

OKASOLAR S is a daylight system especially developed for overhead glazing and unites effective direction-selective sun protection with the use of daylight. The shading system integrated in the cavity creates a comfortable atmosphere in the interior: Along with good transparency it guarantees an even and glare-free illumination with daylight at any time of day or season. Moreover, OKASOLAR S reduces the cooling load and costs for artificial illumination and optimizes the energy balance of a building.
