What does ‘drywall’ refer to in construction?

Drywall refers specifically to a construction material that is made of gypsum plaster pressed between two thick sheets of paper. This material is widely used in the construction of interior walls and ceilings due to its advantages, such as ease of installation, cost-effectiveness, fire resistance, and sound insulation properties.

The two thick sheets of paper provide structural integrity, while the gypsum core offers fire resistance and creates a smooth surface that can be painted or finished in various ways. Drywall is a standard component in modern building practices and is preferred over traditional plaster techniques because it can be installed quickly, reducing labor costs and construction time.

In contrast, other choices provide definitions that do not accurately describe what drywall is. For instance, construction materials made of wood boards instead refer to plywood or other types of wooden sheathing, while a type of exterior wall finishing does not encompass the properties or uses of drywall. Similarly, a temporary barrier used during construction might refer to materials like tarps or partition walls, which serve a different purpose entirely.
