CertainTeed is adding R20 Sustainable Insulation to its family of high-performance fiberglass insulation solutions, helping builders and contractors meet increasing IECC code requirements without the need for additional exterior insulation. Specifically, the new product will meet 2012 IECC requirements that wood-frame walls have at least an R20 thermal performance, which applies to 25 states, or otherwise include R13 cavity insulation coupled with R5 insulation sheathing.

“By adding an R20 product to our line of Sustainable Insulation, we're offering an efficient solution to help our customers meet the newest code requirements in one step while staying within the wall, saving the additional material and labor cost of installing exterior insulation,” said Drew Brandt, vice president of marketing and R&D for CertainTeed's Insulation Group. “Since Sustainable Insulation is third-party verified through a life cycle assessment and EPD, builders and contractors can be confident they're installing the best in thermal comfort and sustainability.”

The product is made from recycled and renewable content, including a plant-based binder, and contains no formaldehydes, dyes, acrylics or unnecessary fire-retardant chemicals and is GREENGUARD Gold Certified for low chemical emissions. It won't settle, accumulate moisture or lose its R-value over time. The product is available unfaced or kraft-faced, and is designed for use in standard wood stud and steel-frame wall assemblies.
