Special Kraft-faced fiberglass batts come in two thicknesses and are what size?

• A. 16 by 32 inches
• B. 24 by 48 inches
• C. 32 by 48 inches
• D. 48 by 96 inches

Answer: (B)

These Kraft-faced fiberglass batts are designed to fit standard framing and come in a couple of thicknesses to provide different insulation levels, but they’re most commonly manufactured in a size that fits between studs spaced 24 inches apart. The standard dimension is 24 inches wide by 48 inches long, which matches typical 24-inch-on-center framing and makes installation straightforward without excessive cutting. The other dimensions listed aren’t the typical Kraft-faced batt size. They would not align with common framing widths or would create awkward, wasteful cuts.
