Kalwall® Offers Revolutionary Daylighting Fenestration System with Nanogel® Translucent Aerogel

February 13, 2004
Product Represents A Breakthrough in Daylighting With "U" Values Not Attainable With Any Other Glazing System Globally

(Boston, MA and Manchester, NH) - February 13, 2004 - Kalwall® + Nanogel® translucent aerogel, a revolutionary fenestration system that offers an NFRC certified system U value of .10 (R-10), four times greater than insulating glass systems, with museum-quality light is now commercially available. The new Kalwall + panels filled with translucent aerogel offer the most insulating, diffuse light-transmitting technology available today. Kalwall® Corporation exclusively manufactures the product, working with Cabot Corporation (NYSE: CBT).

The Kalwall + Nanogel panel itself provides a thermal protection of U=.05 (R-20) with up to 20 percent light transmission, and improved sound attenuation, making it easier for designers to satisfy new stricter building codes. These exceptional benefits allow the system to be used as all or part of a wall or roof structure. The Kalwall + Nanogel system transmits museum-quality light that virtually eliminates glare, hotspots, and shadows.

Nanogel® translucent aerogel material is the unique insulation inside the Kalwall manufactured fiberglass skylight and wall panels. Aerogel materials are known as the best insulating and lightest solid materials in the world. Manufactured exclusively by Cabot through its patented process, Nanogel translucent aerogel is a highly light transmissive, lightweight, nanoporous material, and is permanently hydrophobic, making it both moisture and mildew resistant.

Kalwall + Nanogel skylights were installed on the roof above the heated swimming pool at the Comfort Inn, in Manchester, New Hampshire. "The Kalwall panels with Nanogel let lots of light through, and its insulation value is astounding," said Fred Bailey III, owner and proprietor, Comfort Inn. "Even in the coldest weather, we aren't losing heat through the roof."
