Energy-efficient roof systems increasingly are in demand. Rising energy costs, evolving building codes and greater sensitivity to the effects of urban heat islands all are reasons to specify white, reflective roof systems. It is common sense that using energy-efficient roofing materials results in cooler roof surfaces and less energy spent for air conditioning.
As a result of this demand and media attention in recent years about ENERGY STAR® ratings and reflectivity, acrylic coatings frequently are specified as finish coats for built-up and modified bitumen roof systems and maintenance coatings for existing roof systems, including built-up, modified bitumen, metal, spray polyurethane foam and concrete.
