UltraPly TPO membrane also offers design options with panels available in reflective white, tan or gray, which can help reduce a building’s cooling requirements. White and tan UltraPly TPO membranes meet the California Energy Efficiency Standards for Residential and Nonresidential Buildings (Title 24). These standards define cool roofs in California to have a minimum three-year aged reflectance of 0.55 and a minimum thermal emittance of 0.75 for low-sloped nonresidential buildings.

White and tan UltraPly TPO membranes are listed with the Cool Roof Rating Council (CRRC).
