These are Owens Corning R-13 fiberglass batts, 3.5 in. thick, 15 in. wide and 93 in. long, with a kraft paper facing that acts as a vapor retarder. R-13 is the standard value for 2x4 exterior walls, and the 15 in. width fits the 14-1/2 in. space between studs on standard 16 in. centers. The batts are formaldehyde-free and Energy Star certified. Against generic unfaced batts, the kraft facing saves a separate vapor barrier step; against mineral wool, fiberglass is lighter and easier to cut but less dense and less sound-absorbing.

Owners of Owens Corning R-13 batts generally report the batts hold their shape, cut cleanly and fit standard stud bays, and that the kraft facing staples up without tearing. Complaints center on fiberglass itch and dust during installation and on batts arriving compressed or torn in shipping.
