sheetrock

Sheetrock is a brand name for gypsum board, a common building material used for interior walls and ceilings. It consists of a panel made of gypsum plaster pressed between two thick sheets of paper. Other manufacturers produce similar products, often referred to generically as drywall, gypsum board, or plasterboard.

The gypsum core is typically treated to resist mold and mildew and can also be reinforced with additives to improve fire resistance. Sheetrock panels come in various thicknesses, lengths, and widths to suit different construction needs. Standard panels are usually 4 feet wide and 8 feet long, though longer and wider sheets are available.

Installation involves cutting the panels to size and attaching them to wall studs or ceiling joists using screws or nails. The joints between panels are then covered with joint compound, also known as mud, and reinforced with paper or fiberglass tape. After the compound dries, it is sanded smooth and finished with primer and paint or other wall coverings.

Sheetrock is a cost-effective and versatile material that offers good fire resistance and a smooth surface for finishing. Its widespread use makes it a staple in residential and commercial construction.
