Flex-O-Vent™ Universal Venting Material
Flex-O-Vent is our most economical polyester-based ventilation product. Available in 10’ and 20’ rolls and multiple packaging options, 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.
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.
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.
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.
