What is PVC Membrane Roofing?
Thermoplastic PVC roofing is extremely strong, as its heat-welded seams form a permanent, watertight bond that is stronger than the membrane itself. PVC resin is modified with plasticizers and UV stabilizers, and reinforced with fiberglass non-woven mats or polyester woven scrims, for use as a flexible roofing membrane. PVC is often blended with other polymers to add to the performance capabilities of the original PVC formulation, such as KEE – Keytone Ethylene Ester. Such blends are referred to as either a CPA – Copolymer Alloy, or a TPA – Tripolymer Alloy.
PVC Vinyl roofs are inherently fire resistant due to their chemical composition and have a broader range of fire ratings over common substrates.
PVC has been sold for commercial roofing use for more than 60 years. Vinyl roofing membranes' long life cycle – and the associated lower energy consumption to both produce the raw material and process it into useful products – is a significant factor in their sustainability as a building product.
Vinyl roofs provide an energy-efficient roofing option due to their inherently light coloring. While the surface of a black roof can experience a temperature increase of as much as 90 degrees under the heat of the full sun, a white reflective roof typically increases only 10–25 degrees Fahrenheit.
Vinyl membranes can also be used in waterproofing applications for roofing. This is a common technique used in association with green, or planted, roofs.
