Centerpoint Translucent Systems, a Knoxville, Tenn.–based manufacturer of residential roofing products, has announced a product supply and marketing agreement with specialty chemicals producer Cabot to use Nanogel translucent aerogel in Centerpoint's roofing structures. The translucent roofs will allow filtered daylight to penetrate into home living areas without the energy loss and increased heating and cooling costs associated with traditional glass roof inserts. Currently, three configurations of the system are on display in homes offered by Centex Corp. and D.R. Horton in the coastal Carolinas.
