Gypsum board, commonly known as drywall or plasterboard, is a building material made from a core of gypsum plaster sandwiched between two sheets of heavy paper. It is widely used in construction for interior walls and ceilings due to its ease of installation and finishing. Gypsum board is lightweight, fire-resistant, and provides good sound insulation, making it a popular choice for residential and commercial buildings. In addition to its structural benefits, gypsum board can be finished with paint or wallpaper, allowing for a variety of aesthetic options. It is available in different sizes and thicknesses to suit various applications, including moisture-resistant types for bathrooms and kitchens.
