This is a ten-pack of unfaced R-19 fiberglass batts, each 6.25 inches thick and 24 by 96 inches, giving 1,440 square feet of coverage sized for 2x6 framing. The unfaced design lets wall cavities dry and breathe before drywall goes up, which suits interior partitions, floors above crawl spaces and exterior walls. R-19 is a mid-range cavity insulation: it beats R-13 batts for 2x6 walls but trails spray foam and rigid board on air sealing, since fiberglass alone does not stop drafts. Owners and installers treat it as a straightforward, low-cost way to hit code in wood-frame remodeling, with the usual complaints about itch, dust and the need for a separate vapor barrier in cold climates.

Installers and DIYers describe this as ordinary, serviceable R-19 fiberglass: it fills 2x6 bays, cuts predictably and does what budget cavity insulation should. Complaints center on itch and dust during install and on the need to add a vapor barrier and air sealing for it to perform.
This is R-19 unfaced fiberglass batt insulation, supplied as ten packs that cover 1440 square feet. It is made for residential remodeling. The batts have no paper facing and no vapor barrier, so air can pass through before drywall goes up.
The batts are 6.25 inches thick and fit standard 2x6 framing. They are installed beneath subflooring, in floors and interior partitions, or inside exterior wall cavities. There they reduce heat loss and help control indoor noise.
