Owens Corning R-19 is a kraft-faced fiberglass batt for walls, floors and ceilings where you want a built-in vapor retarder. Each batt is 15.25 in. wide by 93 in. long and 6.5 in. thick, giving R-19 for 2x6 framing cavities. The facing has tabs for stapling to studs, and the fiberglass is formaldehyde-free and Energy Star certified. It suits basement walls, exterior 2x6 walls and floor joist bays; loose fill and unfaced batts cost less but need a separate vapor barrier.
