The new granulated, uncoated finish is designed to be one of the easiest, most cost-effective ways to lower commercial building energy consumption and increase occupant comfort. It handles like a standard roofing product without special installation requirements, is more aesthetically pleasing, and yet maintains a high solar reflectivity, reducing roof temperatures as much as 20 percent. </p><p>“With multiple money-saving and environmental advantages, choosing cool roof technology is a no-brainer when considering a new or replacement commercial roofing system,” says Barbara McDonough, marketing manager for CertainTeed Commercial and Solar Roofing. “Now our CoolStar products offer an even cleaner finished appearance that installs faster, with reduced maintenance requirements.”</p><p>CoolStar is designed to work with a wide range of roof systems, including built-up roofing, SBS, APP and self-adhering modified bitumen. It is extremely flexible and durable, due to the layering of high-quality reinforcements, heavy asphalt coating and highly reflective ceramic granules. This toughness combats the negative effects of natural expansion and contraction caused by heating, cooling, light and moisture. In addition, the brilliant white CoolStar surface is factory applied for hassle-free, one-step installation, which helps reduce labor costs.
