Drywall, also known as gypsum board or plasterboard, is a building material used to create interior walls and ceilings. It consists of a core made of gypsum, sandwiched between two sheets of heavy paper. This material is popular in construction because it is lightweight, easy to install, and provides a smooth surface for painting or finishing. The installation of drywall involves cutting the panels to size, attaching them to wall studs or ceiling joists, and then finishing the seams with joint compound. Once completed, drywall helps improve insulation and soundproofing in a building, making it a common choice for residential and commercial spaces.
