National Coatings: AcryShield Cool-Roof acrylic, water-based roof coatings reportedly helped avoid as many as 24 million pounds of CO2 production in reduced demands for energy across the nation in 2006. The coatings can be applied to a range of substrates, including built-up roofing (BUR), modified bitumen, ethylene propylene diene terpolymer (EPDM), polyvinyl chloride (PVC), chlorosulfonated polyethylene (CSPE) synthetic rubber (Hypalon), metal and asbestos-reinforced Portland cement (Transite). They are designed to provide reflectivity up to three times greater than dark BUR, EPDM, and ModBit roofing, which can provide significant energy savings. Call 800.423.9557 or
