CertainTeed Sustainable Insulation is a kraft-faced fiberglass batt made with a plant-based binder and a minimum of 35% recycled content. The 8-1/4 inch batt delivers R-30 cavity insulation, the thickness that fits standard 2x10 framing. It suits attics, cathedral ceilings and walls where a kraft vapor retarder is wanted. Compared with plain pink fiberglass, it competes on the recycled and low-formaldehyde story rather than on R-value per inch, and it is cut to friction-fit between studs and joists.

Owners and installers describe the batts as easy to handle and cut, with less itch and odor than older fiberglass. Most complaints center on the R-value naming and on batts arriving compressed or short of full thickness.
