The panels are lightweight, shatterproof, and quick to install, providing strong structural performance that supports architectural design while enabling daylighting and energy efficiency.

Manufactured entirely in the United States using a zero-landfill process, Kalwall distributes its products worldwide through a network of more than 60 distributors. A recent development includes the appointment of Dan Wallace as Director of Engineering in January 2025.
