OKASOLAR 3D

High-Performance Sun Protection Grid for Roof Glazing

OKASOLAR 3D is an insulated glazing system with a three-dimensional, highly reflective sun protection grid in the cavity between the glass panes. The geometry of the sun protection grid has been optimised for roof applications. The direct solar transmission is blocked at all times, irrespective of the height of the sun. This effectively reduces the heat gain into the interior of the building. At the same time a large Proportion of diffuse daylight from the northern hemisphere gets into the interior. This results in even light distribution in the interior and significantly less fluctuation in brightness than with direct sunlight.
As facade glazing we recommend our products OKASOLAR W and OKASOLAR F.

OKASOLAR 3D Insulating glass with three-dimensional sun protection grid

Principles of Function OKASOLAR 3D (northern hemisphere)

Thanks to its three-dimensional, highly reflective sun protection grid, OKASOLAR 3D offers:

High-Performance sun protection
Reduced heat gain
Low TSET
High light Transmission
Partial trough-vision to the North
Homogenous appearance without joints
Sufficient daylight and reduction of artificial light
Maintenance and fault-free
Can be easily recycled
Visibility for birds

The special feature of OKASOLAR 3D is that the sun protection grid is integrated into the cavity of the insulated glazing system, so there are special requirements with regard to installation, maintenance or repair, and the entire system can be treated just like standard insulated glazing. The thickness and type of glass depend on structural and building requirements. However, for structural reasons the bending radius is to be limited to 12 m under Deformation.
