Drywall is defined as?

• A. System of interior wall finish using sheets of gypsum board and taped joints
• B. Exterior cladding
• C. Structural sheathing
• D. Steel studs with plaster over

Answer: (A)

Drywall refers to the interior wall finish made from gypsum board panels that are fastened to the framing, with the joints taped and finished with joint compound. This surface is used inside buildings to provide a smooth, paintable finish and fire resistance, but it isn’t the protective exterior layer or the structural substrate.

It differs from exterior cladding, which protects against weather, and from structural sheathing, which provides rigidity and load-bearing support. A system with plaster over steel studs represents a different interior finish method than gypsum board panels.
