This is a 10-pack of R-19 kraft-faced fiberglass batts, each 24 by 96 inches, sized for 2x6 framing. The kraft facing doubles as a vapor barrier, so it suits exterior walls, floor joist bays and unventilated attic spaces. R-19 is the common target for 2x6 exterior walls in moderate climates; thicker batts or rigid foam are needed where codes call for more. Fiberglass batts are cheaper and easier to cut than foam board but demand careful fitting, since gaps and compression cut the rated R-value.

This is a 10-pack of R-19 fiberglass batt insulation for residential framing. Each pre-cut sheet measures 24 by 96 inches. The kraft paper facing acts as a built-in vapor barrier.
The continuous fibrous mats trap dead air pockets, which slows conductive heat flow through wood frames. The facing also stops air from circulating through the cavity. The batts are made for 2x6 walls and floors, subfloor joist bays and unventilated attic spaces.
