Which is another term for gypsum board?

Gypsum board is commonly known as drywall. This material consists of a core made of gypsum plaster and is encased in paper, making it a widely used construction material for walls and ceilings. It is favored for its fire-resistant properties, ease of installation, and versatility. Gypsum board is significant in the context of fire safety, as it can slow the spread of fire and is often used to create fire-resistant barriers in buildings. Understanding terminology related to gypsum board is important for fire fighters, particularly in scenarios involving structural assessments and understanding building materials in fire situations. Other options listed do not refer to gypsum board; for example, stucco is a plaster used for finishing exteriors, lath is a framework used to support plaster, and OSB (oriented strand board) is a type of engineered wood used in construction, all of which are distinctly different from drywall.
