This is a 15 in. wide, 24 ft. long roll of R-15 kraft-faced fiberglass insulation, 3.5 in. thick, sized to fit 2x4 wood-stud walls at 16 in. spacing. The kraft facing acts as a vapor retarder and the fiberglass also dampens sound, so it suits interior and exterior wall cavities. It is a standard mid-range batt, comparable to other R-15 faced rolls but with GREENGUARD Gold certification and a limited lifetime warranty. Each roll covers about 30 sq ft, so larger jobs need several rolls.
