Which component is described by examples such as gypsum, OSB, and plywood panels?

• A. Sheathing
• B. Insulation
• C. Drywall
• D. Framing

Answer: (A)

Panel materials installed over the framing that form the backing for exterior walls and roofs are called sheathing. Gypsum, OSB, and plywood panels all fit this role because they are installed directly onto the framed structure to provide a rigid surface, help transfer loads, and give a solid base for exterior cladding and weather barriers. Drywall is interior finishing, and insulation sits in the cavities, while framing is the structural skeleton. So these materials describe the sheathing.
