Kalwall is the most highly insulating, diffuse light-transmitting, structural composite technology in the world. The company has perfected a unique composite fenestration sandwich panel that combines controlled, usable, natural daylight with the ultimate in energy efficiency. Lightweight, shatterproof, and rapidly installed, Kalwall has unrivaled structural integrity. Kalwall can be all or part of the walls or roof of any building or be an entire freestanding structure. Typical configurations and systems include Wall/Window Systems, Skylights, Clearspan™ Skylights/Skyroof®, Walkways/Canopies, Window Replacements, and Complete Structures. Kalwall is NOT a plastic, polycarbonate or glass. It is far superior in integrity, performance and value to products that superficially may appear similar. Kalwall's primary element is a structural composite sandwich panel formed by permanently bonding, under heat and pressure, specially formulated, fiberglass-reinforced translucent faces to a grid core constructed of interlocked, structural aluminum/composite, thermally broken "I" beams. The panels can be curved or flat, 2-3/4 inches (70mm) or 4 inches (100 mm) thick.

No other company in the world has dedicated more years, resources, creativity and innovation into the science and art of daylighting. Kalwall provides building designers and owners with the most advanced technologies in the world to fulfill their own visions of creating better buildings.
