R15 Kraft-faced fiberglass batts are designed for insulating exterior walls, floors, and ceilings where a vapor barrier is needed. These batts measure 15″ x 93″, making them perfect for 2×4 wall cavities spaced 16″ on center. With a total coverage of 77.5 square feet per bag, they offer a reliable R-value of 15 for enhanced thermal resistance. The kraft facing acts as a built-in vapor retarder to help prevent moisture buildup in walls. Ideal for new construction or remodels, these batts are easy to install and help improve energy efficiency, indoor comfort, and sound control.
