What is another widely used term for gypsum board?

Gypsum board, also known as drywall, is commonly referred to as "Sheetrock," which is a brand name that has become synonymous with gypsum board products. Gypsum board is made from a core of gypsum plaster that is sandwiched between two sheets of heavy paper and is widely used in construction for walls and ceilings due to its fire-resistant properties and ease of installation. The term "Sheetrock" has gained widespread recognition, especially in the United States, making it the preferred term in both professional settings and popular usage. This familiarity with the brand aids in communication and understanding among construction professionals and contractors, making it the most appropriate choice in this context.

The other options do not represent gypsum board: "Chalkboard" refers to a board used for writing with chalk, "Paneling" generally involves wood or composite materials used for interior walls, and "Cement board" is used for specific applications such as backing in wet areas and is distinct from gypsum board in materials and functions.
