Gypsum board, also known as drywall or plasterboard, is a common building material used for constructing ceilings and walls. It consists of a layer of gypsum (a naturally occurring mineral) sandwiched between two layers of paper. Gypsum board is highly versatile, lightweight, and easy to install, making it ideal for both residential and commercial applications. It comes in various thicknesses and sizes, with special types available for moisture resistance, fire resistance, and soundproofing. Gypsum board is the go-to material for creating smooth, flat surfaces and can be easily painted or finished with textures. It is particularly popular in ceiling applications due to its ease of use and affordable cost. In addition, gypsum board is fire-resistant and offers excellent acoustic properties, making it a durable and practical choice for many interior spaces.
