Drywall is most commonly used within the interior of buildings, either homes or commercial spaces. These drywalls are utilized as partitions to divide spaces or rooms into different areas. Drywall, also known as plasterboard, sheetrock or gypsum board, has many advantages over plaster with the main reason being the ease of installation. When used to create walls, drywall panels are hung from wall studs with screws. They are then taped and plastered over with joint compound where the panels meet. There are a variety of different textures that can be applied to the drywall to give it an interesting look, such as smooth and rough finishes.
