LP2

LP2 Ridge Vent

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.

Benefits

 

This vent keeps your system performing at its best by promoting efficient airflow to reduce lint buildup and excess heat, helping prevent moisture damage inside the home. Its enclosed design works to keep out insects, critters, and rain, while the removable cap makes cleaning and maintenance simple and fast. With leak-prevention features built into the design, it helps reduce customer call-backs and gives installers a dependable solution they can trust on every shingle roof application.
