Gyp boards, also known as gypsum boards or drywall, are a staple construction material used for interior walls and ceilings. They are made from a mineral called gypsum and offer a smooth, flat surface that is easy to paint and decorate. Gyp boards are often used in residential and commercial buildings due to their cost-effective and easy-to-install nature. However, there are several synonyms for this material, such as plasterboard, wallboard, sheetrock, and dry lining. Understanding these synonyms can be useful when communicating with builders, contractors, or suppliers, ensuring that the right materials are ordered and used in any construction project.
