Reflective coatings reduce heat

Duranar® SPF Coatings, which are said to reduce a roof system's heat absorption, have been introduced by PPG Industries Inc.'s Coil and Extrusion Coatings Group. Meeting the U.S. Environmental Protection Agency's and Department of Energy's ENERGY STAR® criteria, the cool roof coatings can lower costs and energy consumption by reducing heat, as well as lengthen a roof system's life span with the reduction of heat-induced metal expansion and contraction.

The coatings use infrared reflective pigments and can be used with medium- and dark-colored roof systems, providing more energy-friendly color options. Reportedly, the coatings resist stress caused by acid rain and ultraviolet exposure, as well as gloss and color fading.
