Vapor Retarders / Barriers

Vapor retarders save time, money and energy by reducing moisture migration under concrete slabs and foundations, and through inner walls and ceilings. We have a wide variety of vapor retarder products to choose from that are readily available. 

VaporBlock® high performance vapor barriers/retarders are produced from state-of-the-art resins providing superior physical and performance properties that exceed all the stringent requirements of ASTM E-1745, Class A, B & C. VaporBlock 10 is available in 15’ x 200’ rolls and VaporBlock 15 in 12’ x 200’ rolls along with (Vapor Bond) seaming tape and pipe boot kits (VaporBoot Kit) to provide a complete and thorough system to protect against moisture migration.
