Static prismatic systems

Stationary prismatic systems supply optimal solar protection and perfect light guidance.

The basis of stationary prismatic systems are prismatic plates of 8N acrylic glass (injection-moulded). These are smooth on one side and feature a prismatic structure on the other. Various prism angles are available.

The stationary prismatic systems not only use light control via the prisms themselves. One prism edge is of specular ultra-pure aluminium (AL 99.99). This enlarges the blockage range and completely eliminates direct sunlight. This allows use especially in inclined glass facades and roofs.

The plates are cut to suit and installed in insulated window panes, rooflights and canopy glazing. This guarantees protection from humidity and soiling. This technology is adapted via various prism structures and the orientation of the prismatic plates to the diverse demands in terms of geographic location, inclination of glazing and orientation of the building.

Prismatic systems are mainly implemented as solar protection. They can however also be used for light control, and both functions can be combined with ease.
