PVC 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, however, subject to plasticizer migration.

(a process by which the plasticizers migrate out of the sheet causing it to become brittle.) Thus a thicker membrane has a larger reservoir of plasticizer to maintain flexibility over its lifespan. 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.

Benefits of PVC include the following:


Heat Air Welded seams are easier and cleaner than adhesive based seams like EPDM.

Resistant to more chemicals than TPO, like animal fats and jet fuel, making PVC ideal on restaurants and near or on airports.

Can be both mechanically attached and fully adhered.

Can be used to retrofit old metal roofs and the system can include additional insulation.

Hi,
PVC roofing is one kind of single ply roofing, which means it consists of one layer manufactured in a factory. A PVC roofing membrane is made of thick, flexible UV-resistant thermoplastic material.
Thanks
