Drywall is commonly referred to as gypsum board because it is primarily made from gypsum, a natural mineral, which is sandwiched between two sheets of heavy paper or fiberglass mat. This construction provides the board with its structural integrity, making it lightweight yet strong, ideal for interior walls and ceilings. The term "gypsum board" accurately reflects the main component used in its production and emphasizes its purpose in building construction. It is important to note that while "plasterboard" is also a term used interchangeably with drywall, "gypsum board" is the most technically accurate descriptor based on the material's composition. Other terms like wood paneling and cement board refer to entirely different products used in construction and do not relate to drywall.
