12 Bags Rockwool Comfortbatt R15 Stone Wool Insulation
Value & Price Guide
Got 12 new bags of Rockwool Comfortbatt insulation. This is the R15 stuff for 2x4 wood studs, 16 inch on center. It's way better than fiberglass because it doesn't sag and it's fire resistant. Really easy to cut and install, plus it helps a ton with soundproofing too. Bags are still sealed and ready to go.
