OKATECH expanded metal

Exclusive daylight system: Insulating glass with expanded metal insert

Glass facades with OKATECH expanded metal inserts always set visual accents. The copper and aluminum inserts are not only attractive elements of design but also function as direction-selective daylight systems and ensure effective sun and glare-protection.

During the day, they give the building shell a special glow and the façade has a metallic shimmer in the sunlight. At night, when artificial light is used, they allow deep views into the interior.
In addition to façades and parapets, OKATECH expanded metal is also suited for sophisticated interior design applications.
