Both residential and commercial construction use drywall, also known as gypsum board or plasterboard, to construct walls and ceilings. The surface is smooth and flat since it is made from gypsum, a soft mineral that is dried and pressed between two thick sheets of paper. Drywall is a versatile and affordable option for homeowners and builders alike, and is known for its ease of installation and repair. In this article, we will explore the different types of drywall, the steps involved in installing and finishing it, as well as its advantages and disadvantages.
Definition
The term drywall refers to a construction material used for the construction of walls and ceilings in buildings, also known as gypsum board or wallboard. The panel is made of gypsum plaster sandwiched between two heavy sheets of paper or fiberglass.
History
It was first introduced in the early 20th century as a replacement for plaster and lath construction. Its ease of installation and lower cost made drywall more popular in the 1940s and 1950s. Today, it is the most common material used for interior walls and ceilings.
Composition and Structure
Wallboard consists of a gypsum core sandwiched between two sheets of paper or fiberglass. The gypsum core is made of a mineral called hydrous calcium sulfate, which is heated and dehydrated to create a fine powder. This powder is then mixed with water to form a paste, which is then poured onto the sheets of paper or fiberglass mats to create the panels. Once the panels have dried, they are cut to the desired size and shape for installation.
