Tex-Cote Cool Wall coating systems are said to incorporate the same technology used in stealth bombers and other military vehicles. According to their manufacturer, the heat-reflective pigments that hide airplanes can keep the outer walls of a house up to 40 degrees cooler than competing exterior paints or coatings, leading, in turn, to lower electric bills. The U.S. Department of Energy backs the claim, reporting in a recent study that Cool Wall can reduce energy costs by as much as 21.9 percent. Fade-resistant properties also help keep maintenance to a minimum. Choose from numerous colors in textured or smooth applications. Textured Coatings of America, 800.454.0340; www.texcotehomes.com.
