Vapor Retarder Receives Innovative Technology Award

CertainTeed Corporation's new MemBrain™, a patented smart vapor retarder, has won an Innovative Housing Technology Award in the Energy category from the NAHB Research Center and EH Publishing, the publishers of TecHome Builder, CE Pro and Electronic House.

CertainTeed is a member of the National Council of the Housing Industry — the Supplier 100 of NAHB.

Made of polyamide film, MemBrain allows excess moisture trapped in a wall cavity to escape, changing its permeability from less than one perm at low humidity to more than 20 perms when the relative humidity is high.

"MemBrain allows closed building envelope systems to increase their drying potential with seasonal climatic changes, helping to reduce the risk and liability concerns due to excess moisture in homes and buildings, a growing concern today," says Glenn Singer, manager of building science for CertainTeed's Insulation Group.
