R-19 kraft faced fiberglass batts are made for 2x6 exterior wall cavities. The 6.25-inch thickness fills a 2x6 stud bay, and the attached kraft paper facing goes inward as a vapor retarder against humid room air. The glass wool is formaldehyde free and resists settling, so the rated R-value holds up over time. Ten bags cover about 1,336 square feet, which suits a whole-house exterior wall job rather than a patch. Against unfaced batts, the facing saves a separate vapor barrier step; against blown-in or spray foam, batts are simpler to cut around wiring and cheaper to install yourself, but they leave gaps if the framing is uneven.

These R-19 kraft faced fiberglass batts are made for insulating 2x6 exterior walls. The glass wool is formaldehyde free and resists settling over time. A kraft paper facing is attached to the batt and acts as a vapor shield to stop moisture buildup in the framing.
The batts have a 6.25 inch deep profile that fits 2x6 stud spacing. Install them with the facing toward the inside, which keeps humid room air from freezing on the outer siding.
Ten bags come in a package and cover about 1336 square feet.
