What Is a Drywall Sheet?
A drywall sheet is a construction material that is typically used to make the interior walls and ceilings of houses. It is usually made of gypsum plaster that has been pressed between two thick sheets of paper. It is typically light in color so that it can be easily painted in the desired interior color. Other common names for a drywall sheet are wallboard, Sheetrock®, and gypsum board.
