When installing unfaced batt insulation, how is it secured?

• A. pressure fit
• B. taped
• C. wired
• D. stapled

Answer: (A)

Unfaced batt insulation is held in place by friction between the insulation and the framing. When you install it between studs, you cut it to fit and push it in so it fits tightly. Without a facing to staple or tape, there isn’t a fastening method used on the batt itself—the snug, pressure-fit between the studs keeps it in position. The drywall or other finish will add stability later, but the batt relies on that tight fit rather than staples, tape, or wires.
