PVC roofing materials are a highly-engineered, flexible, thermoplastic membrane-manufactured using a UV resistant poly-vinyl chloride.
It provides excellent weathering characteristics, high tension strength and long-term flexibility. It also exhibits resistance to harsh chemicals and industrial pollutants.
There are basically three types of single ply roofing: TPO, PVC, and EPDM.
TPO roofing is one of the latest single ply, flat roofing materials on the market. Current membrane formulations are reinforced with a polyester fabric and manufactured using an ultraviolet-resistant thermoplastic polyolefin formulation. TPO comes in several thicknesses. It’s designed for use in mechanically fastened and adhered roofing applications in new, re-roof and recover roof constructions. It is fire and chemical resistant and contains UV inhibitors for added longevity.
EPDM roofing has superior weatherability through a wide range of temperatures and conditions and demonstrates superior ozone resistance. EPDM membranes are available in several thicknesses, with or without polyester scrim reinforcement and can be installed in ballasted, mechanically-fastened or adhered applications.
