Special Kraft-faced fiberglass batt insulation comes in how many thickness options?

• A. One
• B. Two
• C. Three
• D. Four

Answer: (B)

Two thickness options because batt insulation is made to fit the two most common framing depths. Kraft-faced fiberglass batts typically come in 3.5 inches to fit standard 2x4 walls and 5.5 inches to fit standard 2x6 walls, giving a snug, gap-free install and the needed R-value for those cavities. The kraft facing acts as a vapor retarder and helps with installation, but the reason there are two options is to match these common wall depths.
