Universal Venting Material

Flex-O-Vent Universal Venting Material vents, protects and lasts like no other. While polyurethane products constantly expand (as they soak up water) and contract (as they dry out) causing them to disintegrate and fail, Flex-O-Vent offers 40 years of Weather-Tite performance. Its specially formulated polyester— manufactured from recycled material—prevents moisture absorption and holds together to help keep out pests. It’s also extremely durable, flame-resistant, clog-resistant, and tear-resistant.


Flex-O-Vent is not only an economical choice, it’s a long-term solution that provides plenty of cooling air flow, which is vital to meet building codes, reduce utility costs, and minimize long-term building damage caused by improper ventilation.
