VaporBlock® Plus™ 20 Mil Vapor Retarder/Gas Barrier is a seven-layer, co-extruded vapor barrier made from state-of-the-art polyethylene and EVOH resins to provide unmatched impact strength and superior resistance to gas and moisture transmission.
VaporBlock® Plus™ is a highly resilient under slab / vertical wall vapor barrier designed to restrict naturally occurring gases such as radon and methane from migrating from the ground into
the concrete slab or crawl space. VaporBlock® Plus is more than 100 times less permeable than typical high-performance polyethylene vapor retarders against Methane, Radon, and other harmful VOCs.
VaporBlock® Plus™ is available in 10’ x 150’ rolls
