Of course, too much daylight shining through a traditional glass window or skylight causes blinding glare and annoying reflections and shadows. Solar heat gain from glass taxes a building's HVAC system.
Conversely, Kalwall translucent panels eliminate the eye-straining trouble spots, filter out harmful light, and provide balanced lighting and controlled heat gain. Kalwall offers light transmission ranges from 3% to 75%. (The best of both thermal efficiency and light transmission is provided by Kalwall with Nanogel with R-20 at 20% light transmission). The system provides insulation that is four times better than insulating glass units or any other light-transmitting system.
Because of their superior insulating performance, the panels pay for themselves in energy, maintenance, and installation cost savings. Kalwall is also rugged, shatterproof, vandal-resistant, and maintenance-free, further lowering expenses over time by reducing capital outlays for replacement.
Kalwall panels were tested recently for compliance with standards specified by both the General Services Administration (GSA) and the Department of Defense (DoD) in their Unified Facilities Criteria: DoD Minimum Anti-Terrorism Standards for Buildings. Up until now, the only glazing material allowed under the anti-terrorism standards was laminated glass, structurally glazed in a heavy steel frame. With the qualification of the Kalwall system, the advantages of translucent daylighting, combined with excellent thermal performance, are now available to the design professional.
Kalwall's "revolutionary new daylighting system", Kalwall+ Nanogel, wins 2003 Innovative Daylighting System Award from The Sustainable Buildings Industry Council.
Specs: Kalwall Structural Thermal Break Composite · 1-3/4 inches (44 mm) Non-conductive break · Stronger than aluminum · Passes all fire testing to 1200 degrees F · Superior insulation in panels -- "U" .10 or less · Stops condensation -- CRF 80+
