Fiberglass batt insulation is the most basic and cheapest way to insulate the walls of your home or business. We offer several different facing options in fiberglass batts: Unfaced, Kraft Facing, F.S.K. Facing, and Encapsulated (Fire-Rated Facing). For 2x4 walls, we offer R-13 and R-15 Kraft Facing batts. For 2x6 walls, R-19 and R-21 Kraft Facing batts. For our customers with health concerns or those looking for something a little more environmentally friendly, we also offer formaldehyde-free or high-density batts. So depending on your particular situation, we will be happy to work with you to find out what fiberglass batt will best suit your needs.
