Which form is designed as a loose-fitting blanket or batts for filling wall cavities?

• A. Pre form
• B. Board
• C. Wrap
• D. Batt insulation

Answer: (C)

Batt insulation, also called blanket insulation, is designed as loose-fitting blankets or batts that fill wall cavities. It’s usually made from fiberglass or mineral wool and comes in widths to fit typical stud spacings. The flexible, loose form lets you press and cut it to fit around outlets and around any irregular sides of the cavity, trapping air within the fibers to slow heat transfer. This makes it ideal for filling wall cavities evenly. By contrast, rigid board insulation uses solid panels, and wrap serves as a barrier or cover rather than a cavity-fill material.
