Flex-O-Vent™
Flex-O-Vent is our most economical polyester-based ventilation product. Available 20-foot rolls, Flex-O-Vent won’t absorb moisture, which can freeze and block all ventilation. It features M63 Marco proprietary adhesive for superior hold, easy one-person installation and a 40-year limited warranty.Our 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 keep out pests. It’s also extremely durable, flame resistant, clog resistant, and tear resistant.
How do I install Flex-O-Vent™?
Step 1: Make sure panel is free of dust and debris. If not pre-cut, cut 2” slot at ridge. Measure and mark where the ridge cap will sit on the panel.
Step 2: Start from the end of the ridge, rolling out Flex-O-Vent along the length of the ridge (both sides), making sure the vent sits “up-slope” from the edge of the ridge cap.
Step 3: Apply ridge cap, compressing material between the ridge cap and major rip. Fasten at the major rib using a screw gun set to at least 2700 rpm.
