The Thickest Crawl Space Vapor Barrier

Designed and engineered to stop the infiltration of moisture and soil gases, the 250 mil liner is equipped with a double-layer of closed cell foam material, making it the thickest crawl space vapor barrier available on the market. Its additional padding provides extra durability, which allows it to withstand heavy storage.

The double layer of closed-cell foam is enclosed by one side that is aluminized, while the other side is a heavy duty polyethylene. The aluminized side diffuses soil gases, including radon, and reflects heat back into the crawl space and basement, while the polyethylene side provides the liner its strength.
