R13 is the thermal resistance rating of the batt. It is the common value for insulating a 2x4 wall cavity.

What are the batt dimensions?

Each batt is 3.5 inches thick, 15 inches wide and 93 inches long. That fits standard stud spacing and 8-foot wall heights with trimming.

Can I use it in a ceiling or attic?

It is designed for wall cavities. Attics and ceilings usually need higher R-values and unfaced or specially faced products.

Does the kraft facing need a separate vapor barrier?

The facing acts as a vapor retarder. In most wall assemblies you do not add another barrier over it, and the facing must be covered with drywall or another approved finish.

Press the batt into the cavity with the kraft facing toward the heated side of the wall, then staple the flanges to the stud faces. Wear gloves, eye protection and a mask.

Can it be cut to fit?

Yes. Cut the fiberglass with a utility knife and trim the facing to fit narrow or irregular cavities.

Our take on the Owens Corning R13 Kraft Faced Fiberglass Insulation

Owens Corning R13 Kraft Faced Fiberglass Insulation is a batt of fiberglass insulation with a kraft paper facing on one side. Each batt measures 3.5 inches thick, 15 inches wide and 93 inches long, giving R13 thermal performance for 2x4 exterior walls and interior partitions. The kraft facing acts as a vapor retarder and provides flanges for stapling to studs. It is a standard, widely available choice for wood-frame wall cavities, competing with other R13 batts on facing type and fit rather than on added features.
