Outstanding weathering characteristics, energy efficiency, installation ease and durability are among the many advantages of polyvinyl chloride PVC roofing systems. PVC roofing has been in the roofing industry in the United States since 1970.
PVC is a vinyl single ply roof membrane. The PVC membrane is installed on the roof by heat welding the overlapping edges with an electrically powered heat welder or hand held welder. When the laps are heat welded together, the seam overlay fuses together making the material seamless and as the membrane cools it creates a watertight bond.
This hot-air welded, polyester scrim-reinforced membrane for durability and strength, has a white reflective surface, and is available in 45-mil and 60-mil thicknesses. This material tends to be more expensive than TPO, but it is well known for long-term performance and is naturally fire-retardant.
