GAF introduces EverGuard Extreme TPO single-ply roofing
October 8, 2011 - Rooftop solar panels can reach temperatures as high as 200ºF, says GAF, leading to possible premature roofing membrane failure. The company says it has addressed this issue with EverGuard Extreme TPO single-ply roofing, which is designed with higher reflectivity and heat resistance. It can survive over 180 days at 280ºF before failure occurs; according to GAF, that’s six times the required performance, at a temperature 40 degrees higher than current standard requirements. It has survived accelerated weathering tests designed to simulate about 45 years of exposure to South Florida sun. EverGuard Extreme TPO is available in white in both 60-mil and 80-mil, as smooth and fleeceback membranes.
