Flex-O-Vent™ Universal Venting Material

Flex-O-Vent is an economical choice that provides plenty of cooling air flow to help you meet building codes, reduce utility costs and minimize long-term building damage caused by improper ventilation. Unlike polyurethane products that constantly expand (as they soak up water) and contract (as they dry out) causing them to disintegrate and fail, Flex-O-Vent prevents moisture absorption. Made from specially formulated polyester that is manufactured from recycled material, it’s extremely durable, flame-resistant, clog-resistant and tear-resistant.

With Flex-O-Vent, one size fits most panels. Installation is a simple two-step process easily handled by one installer. Flex-O-Vent comes in easy-to-handle 10-foot rolls (mirroring most ridge cap lengths) or larger 20-foot rolls if you prefer. It is easily cut with scissors or a utility knife and a double bead of M63 adhesive holds Flex-O-Vent securely in place until the ridge cap is installed.
