Selective solar protection
OKATECH Insulating Glass with a metal interlayer can integrate many different designs of wire mesh, expanded metal or perforated metal sheet as a design element with variable functions. The material and the manufacturing process determine not only the aesthetics, but also the function.

“High sun” is almost entirely blocked; “low” sun is allowed to pass.
Allows for solar heating in the winter and summer thermal protection.
Natural light is both refracted and reflected leading to stunning changes in the illumination effects.

What effect does the "Louver" design (GKD) have in a vertical façade?
When the sun is high, the mesh screens the sun completely. Total solar energy transmittance is very low, with values of around 7-15%.
At lower elevation angles, total solar energy transmittance increases. At right angles to the glass (corresponding to an angle of elevation of 0°) OKATECH achieves the highest transmission, which is also ideal for transparency.

This means seasonal solar protection for places with widely varying angles of incidence: solar heating contributions in the winter and thermal protection in the summer.
