What is the registered tradename for gypsum board?

• A. Hardboard
• B. Sheetrock
• C. Plasterboard
• D. Plywood

Answer: (B)

The registered tradename for gypsum board is Sheetrock. This term has become widely recognized and is often used interchangeably with gypsum board in construction and renovation contexts. Sheetrock is a brand owned by the United States Gypsum Company (USG) and refers specifically to their line of gypsum board products. Gypsum board itself is a building material made of a gypsum core that's encased in a paper liner, primarily used for interior walls and ceilings. The name Sheetrock has become so synonymous with gypsum board that many people refer to all types of gypsum board by this name, regardless of the manufacturer. In contrast, other terms in the choices refer to different materials: hardboard is a type of dense fiberboard, plasterboard is a more generic term that could apply to a type of gypsum board, but is not a registered trademark, and plywood is a completely different material made from layers of wood veneers bonded together.
