Kalwall's® history dates to 1955 when Robert Keller created the Kalwall® translucent sandwich panel--a building composite far superior to acrylic, polycarbonate or glass in many ways. From museum quality daylighting, thermal and solar efficiency, safety and security, Kalwall wall and Skyroof™ panels always have been a game changer. It is a legacy the Kal-Lite Division is proud to be a part of. Over time, this has given us the opportunity to meet the needs of an extremely wide range of customers around the world, but it does not stop there. As part of this history, Kal-Lite continues to provide architects, building owners, and designers with the most advanced and effective flat sheet FRP solutions available.
