Polyvinyl Chloride (PVC)

Polyvinyl Chloride (PVC) is a single-ply reflective roofing membrane made from polyprophylene and ethylene-propylene rubber polymerized together. PVC can be installed either fully adhered, mechanically attached, fleece back adhered, or as a self-adhering sheet, with the seams of the roofing system sealed with liquid adhesives or welded together. PVC membranes are produced in numerous colors, though gray and white are the most common.

PVC sheets are produced by calendaring, spread coating or extruding, and typically are reinforced with polyester or glass-fiber mats or scrim. PVC sheets contain plasticizers and stabilizers, as well as other additives to impart flexibility and achieve other desired physical properties. Some membranes are available with nonwoven fleece backing adhered to the underside of a sheet.
