Our premier custom-cut vent strip includes polyester vent material inserts for a snug fit and optimum ventilation at a cost lower than traditional fans and louvers. Made with recycled materials, it features a 40-year limited warranty and our proprietary adhesive for a superior hold. Our patented LP2 offers superior Net Free ventilation that reduces condensation and helps lower utility costs.

LP2 comes 75 feet to a box, in 25 three-foot sections. With LP2’s double bead of industrial strength adhesive, one person can simply remove the peel-and-stick strips to apply LP2 to the metal roof, then secure the ridge cap over the LP2 with fasteners or nails. It’s that easy!
