At this week’s International Builders’ Show, CertainTeed (Booth W1271) will unveil fiberglass insulation that helps building professionals control moisture within wall cavities by allowing excess moisture to escape, thus reducing the risk of mold and mildew growth.
The manufacturer’s DryRight™ Fiber Glass Insulation is faced with MemBrain™, a breathable vapor-retarding film that has been used in Europe for nearly a decade. Since 2002, Certain Teed has been marketing the advanced film as a separate vapor retarder with unfaced insulation. But during the last year, it has developed techniques that allow MemBrain to adhere to fiberglass batts and rolls as facing.
“DryRight helps builders protect home buyers from excess moisture that can lead to unwanted mold and mildew, while at the same time easing their minds about mold-related legal claims,” said Howard Deck, president of the company’s Insulation Group. “The unique MemBrain technology is revolutionizing how building professionals in the United States think about vapor retarders and their role in managing moisture in walls.”
The molecular-scale pores of MemBrain open under moist, humid conditions during the cooling season, allowing moisture vapor to pass. When indoor humidity is low during the heating season, the pores close to block vapor transmission from passing through the wall where it can condense. DryRight is 1 perm or less at normal conditions and increases to greater than 30 perms as the humidity in the wall cavity climbs to near 90%. This process allows closed building envelope systems to increase their drying potential with seasonal climatic changes.
Available in R-13 and R-19 batts, DryRight is offered throughout North America. It features a wide friction fit design and can be installed quickly, without the need for stapling.
Like other CertainTeed fiber glass insulation products, DryRight is GREENGUARD® certified. Using the strongest environmental protocols, it is regularly tested for low emissions of formaldehyde, VOCs, respirable particles and other pollutants.
