GAF TPO Roofing - Smooth EverGuard® Extreme™ 50 & 70

Building-integrated photovoltaics (BIPV) systems are typically mounted directly to a low slope roofing membrane. Temperatures are as high as 190˚F in close proximity to solar panels mounted directly to white roofing membrane. Standard TPO formulations can fail in extreme accelerated heat aging studies in as little as 40 days. Without enhanced UV and heat protection packages, membranes will be subject to premature failures. Removing BIPV and repairing failed roofing membrane is expensive. Installed pricing for BIPV ranges from $4.00-6.50 per watt. These arrays are typically expected to have a useful life of 20-25 years. GAF scientists were the first to use the new Atlas Ultra Accelerated Weathering Test Unit. This unit collects and concentrates sunlight producing the equivalent of 40 years exposure in only 12 months. EverGuard Extreme TPO membranes survived 13 months under these conditions without signs of failure.
