Which term is commonly used to refer to gypsum wallboard in the construction industry?

• A. Sheetrock
• B. Concrete
• C. Brick
• D. Glass

Answer: (A)

Gypsum wallboard is most commonly referred to in the industry by its trade name Sheetrock. This term comes from a brand that became so widely used that it often stands in for the product itself, much like other brand names that turn into everyday language. Sheetrock denotes the gypsum core sandwiched between paper facings, which is used for interior walls and ceilings.

The other options don’t fit because they describe entirely different materials: concrete is a hard, cast building material made from cement and aggregates; brick is a masonry unit; glass is a transparent glazing material. None of these are used as a general term for gypsum wallboard.
