When it comes to single ply membranes, Keehn Commercial Roofing offers WHITE PVC Flexion rolled membrane. Flexion outperforms standard PVC membranes: This co-polymer PVC alloy is a DuPont product that provides chemical resistance and elasticity superior to other standard PVC membranes. Flexion has a Class A UL-790 Fire rating, and an FM severe Hail Rating for UNMATCHED DURABILITY. Unlike traditional Black EPDM Rubber, Flexion is a highly reflective white material reflecting 83% of UV rays keeping both your building and materials cool. This drastically reduces expansion and contraction of the membrane which keeps the seams intact and your building watertight literally for decades.We offer a 60 Mil option with a 25 year non-prorated warranty or a 50 Mil with a 15 year non-prorated warranty. This system partnered with our factory trained, heat welded application gives you the peace of mind that comes with one of the finest membrane systems in commercial roofing today.
