CertainTeed R20 Sustainable Insulation

CertainTeed is adding this new fiberglass insulation to its family of high-performance products to meet 2012 IECC requirements that wood-frame walls have at least an R20 thermal performance. Made from recycled and renewable content, including a plant-based binder, the product contains no formaldehydes, dyes, acrylics, or unnecessary fire-retardant chemicals, and is Greenguard Gold-certified for low-chemical emissions. Sustainable Insulation is available unfaced or kraft-faced for standard wood-stud and steel-frame wall assemblies.
