Plasterboard, also known as drywall or gypsum board, is a building material used for constructing interior walls and ceilings. It consists of a core made of gypsum, sandwiched between two sheets of heavy paper or fiberglass. This material is popular in construction because it is lightweight, easy to install, and provides a smooth surface for painting or wallpapering. Plasterboard comes in various types, including moisture-resistant and fire-resistant options, making it suitable for different environments, such as bathrooms or kitchens. It is typically available in large sheets, which can be cut to size, allowing for quick and efficient installation in both residential and commercial buildings.
