Owens Corning R-13 Unfaced Batts are flexible fiberglass insulation for wood or metal framing in walls, ceilings and roofs. The 3.5-inch thickness gives R-13, a common value for 2x4 wall cavities. Unfaced batts are the basic choice: they cost less than faced or mineral wool products and let you add your own vapor barrier, but they offer no built-in radiant barrier and need careful handling. They suit DIYers insulating stud walls, rim joists and attic ceilings where a kraft or foil face isn't required.

Owens Corning R-13 Unfaced Batts are flexible fiberglass insulation for roof and ceiling applications and for interior and exterior walls. They install in wood or metal framing cavities or between furring channels.
The batts are inorganic and non-corrosive to steel, aluminum and copper. They are dimensionally stable and will not decay or slump in the cavity. They also help with interior noise control and meet thermal specifications.
The batts are easy to handle and install. Staple them or friction-fit them, and trim them with a utility knife.
