What is gypsum board commonly used for?

Gypsum board, commonly known as drywall or plasterboard, is predominantly used for constructing interior walls and ceilings. This building material is valued for its fire-resistant properties, ease of installation, and smooth finish, which allows for painting and other decorative treatments. When installed in interior spaces, it contributes to creating partitions, and it can also help to enhance the overall acoustic performance and thermal insulation of a building. Given its characteristics, gypsum board is specifically designed for these environments, making it the go-to choice in residential and commercial construction for interior applications.

The other options refer to applications where gypsum board is not typically utilized. For instance, sub-flooring sheathing generally requires materials with higher durability and moisture resistance, such as plywood or oriented strand board. Roof fascia and soffits usually call for materials that can withstand outdoor exposure and varying weather conditions, which are not properties of gypsum board. Roof sheathing, providing structural support for roofing materials, also relies on sturdier materials to handle environmental stresses and loads, rather than gypsum board, which is not designed for such structural applications.
