New DryRight™ Fiber Glass Insulation Helps Builders Prevent Mold, Mildew Growth By Allowing Moisture To Escape Wall Cavities

(HIT) - New DryRight™ Fiber Glass Insulation by CertainTeed Corporation is faced with unique MemBrain™ film to help building professionals control moisture within wall cavities. A powerful, first-of-its-kind combination of fiber glass insulation faced with breathable MemBrain film, DryRight reduces the risk of mold and mildew growth when installed properly.

The film’s molecular-scale pores open under moist, humid conditions during the cooling season to allow moisture vapor to pass. When humidity is low inside during the heating season, the smart film’s molecular-scale pores close to block vapor transmission. Specifically, the permeance of DryRight is 1 perm or less at normal conditions and increases to greater than 30 perms when the humidity changes to near 90 percent. This process allows closed building envelope systems to increase their drying potential with seasonal climatic changes.

"DryRight helps builders protect homebuyers from unwanted mold and mildew, while at the same time easing their minds about mold-related legal claims," says Howard Deck, President of CertainTeed’s Insulation Group. "Our unique MemBrain technology, which has been successfully used in Europe for a decade, is revolutionizing how building professionals in the United States think about vapor retarders and their role in managing moisture in walls."
Available in batts and rolls in R-13 and R-19, DryRight is available nationwide. It features a wider friction fit design and installs fast without need to staple. DryRight is tough insulation with the same high tensile strength of traditional poly.

"DryRight addresses homebuyer’s growing concern for healthy homes and provides builders peace of mind, due to the reduced risk and liability associated with moisture," says Deck.

As with other CertainTeed fiber glass insulation, DryRight is GREENGUARD® certified. It is regularly tested for low emissions of formaldehyde, VOCs, respirable particles and other pollutants using the strongest environmental protocols.
