This is a kraft-faced fiberglass roll rated R-19, sized for 2x6 wood-framed walls, floors and crawl spaces with 16-inch on-center studs. The paper facing acts as a built-in vapor retarder, so it suits concealed exterior wall cavities where moisture control matters. It is formaldehyde-free and carries GREENGUARD Gold and SCS indoor air quality certifications, which puts it ahead of many plain unfaced batts on air-quality credentials. Rolls are made for long, unobstructed runs, so walls broken up by blocking or wiring take more cutting than precut batts.
