50x Less Permeable
Raven VaporBlock® Plus™ 20
Moisture & Vapor Barriers
Underslab Moisture and Gas Barrier
VaporBlock® Plus™ 20 is a seven-layer co-extruded barrier made from state-of-the-art polyethylene and barrier resins that provide unmatched impact strength as well as superior resistance to gas and moisture transmission. VaporBlock® Plus™ 20 is a highly resilient underslab/vertical wall barrier designed to restrict naturally occurring gases and is more than 50 times less permeable than typical high performance polyethylene vapor retarders against methane, radon and other harmful VOCs.
VaporBlock® Plus™ 20 can be installed as part of a passive or active control system extending across the entire building including floors, walls and crawl spaces. When installed as a passive system, it is recommended to include a ventilated system with pump(s) that can be converted to an active control system with properly designed ventilation fans.
VaporBlock® Plus™ 20 works to protect your flooring and other moisture-sensitive furnishings in the building’s interior from moisture and water-vapor migration, greatly reducing condensation, mold and degradation.
