Sheetrock is a brand name for a type of drywall, which is a building material used to create interior walls and ceilings. It consists of a core made of gypsum, sandwiched between two sheets of heavy paper. This material is popular in construction because it is easy to install, cost-effective, and provides a smooth surface for painting or finishing. In addition to its use in residential and commercial buildings, Sheetrock is also available in various types, including moisture-resistant and fire-resistant options. These specialized versions are designed for specific environments, such as bathrooms or areas requiring enhanced safety measures.
