What does the term "drywall" refer to?

A type of insulation material

A panel made of concrete for exterior walls

A panel used to create interior walls and ceilings, made of gypsum plaster

The term "drywall" refers specifically to a panel used for constructing interior walls and ceilings, made primarily of gypsum plaster sandwiched between two sheets of heavy paper or fiberglass mat. This construction method allows for efficient building of non-load-bearing walls and ceilings, making it a widely used material in both residential and commercial construction.

Drywall is favored for its ease of installation, finishing capabilities, and effectiveness in providing a smooth surface ready for painting or wallpaper. It also contributes to sound attenuation and fire resistance, depending on the specific type used.

Other materials, such as concrete panels, are utilized for exterior walls, while flooring materials serve entirely different functions within a building. Insulation serves to improve thermal efficiency, but it is not classified as drywall. Hence, the correct description of drywall is encapsulated in the choice highlighting its role as a gypsum-based panel for interiors.
