Drywall

Drywall construction, a type of construction in which the interior wall is applied in a dry condition without the use of mortar. It contrasts with the use of plaster, which dries after application.

The materials used in drywall construction are gypsum board, plywood, fibre-and-pulp boards, and asbestos-cement boards. The large, rigid sheets are fastened directly to the frame of the building with nails, screws, or adhesives or are mounted on furring (strips of wood nailed over the studs, joists, rafters, or masonry, which allow free circulation of air behind the interior wall).
