CertainTeed is strengthening 15 of its highly reflective, low-slope CoolStar™ roofing products with an enhanced ceramic granule surface. 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, according to the company. 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. It also meets ENERGY STAR and California Title 24 requirements. For more information, visit www.certainteed.com.
