Sure-Flex PVC FRS FleeceBACK membrane is composed of a unique combination of Elvaloy copolymer, fiberglass scrim and polyester fleece backing. This membrane is designed to enhance weatherability, flexibility, and toughness. The fleece backing enhances puncture resistance and provides a separating layer for rough or asphalt substrates. FleeceBACK PVC FRS membranes are manufactured using a state-ofthe-art extrusion process for complete scrim encapsulation. The PVC is reinforced with a high strength fiberglass scrim and enhanced with fleece, creating a very tough, durable and versatile sheet that is ideal for re-roofing or new construction projects. This product can be used in fully adhered and mechanically fastened applications. Carlisle's Sure-Flex™ PVC formulation delivers excellent weatherability, flexibility and toughness, and the fiberglass reinforcing scrim provides additional dimensional stability to the sheet. In addition to providing a builtin separation layer for rough concrete decks or existing asphaltic-based roofi ng systems, the fleece backing enhances the membrane's puncture resistance.
