GYPSUM PLAIN BOARD / PANELS
Gypboard Plain plasterboard is a standard gypsum board consisting of an aerated gypsum core encased in and firmly bonded to, strong paper liners. It is a panel made of gypsum plaster pressed between two thick sheets of paper. It is used to make interior walls and ceilings. Drywall construction became prevalent as a speedier alternative to traditional lath and plaster. It is suitable for use in most system applications where normal fire, structural and acoustic levels are specified.
Gypsum board is often called drywall, wallboard, or plasterboard. It differs from other panel-type building products, such as plywood, hardboard, and fiberboard, because of its noncombustible core and paper facers. When joints and fastener heads are covered with a joint compound system, gypsum wall board creates a continuous surface suitable for most types of interior decoration.
ADVANTAGES OF GYPSUM BOARD
EASE OF INSTALLATION
Gypsum board building systems are easy to install for several reasons. Gypsum board panels are relatively large compared to other materials, so they quickly cover large wall and ceiling areas. Gypsum board assemblies require only a few tools for their construction. Gypsum board can be cut with either a utility knife or a variety of saws, and it can be attached with a variety of fasteners, including screws, nails, and staples. It can also be adhesively attached to many substrates. Gypsum board is a lightweight material. Two workers can easily handle most panels and cover large areas in very short time periods. Gypsum board is easily finished using either a few hand tools or relatively modest machines. Gypsum board installers can quickly learn most application techniques in a few hours.
Gypsum board is an excellent fire-resistive building material. It is the most commonly used interior finish where fire resistance classifications are required as it serves as a heat-insulating barrier. Moreover, tests conducted in show that gypsum board has a low flame-spread index and a low smoke-density index. When installed in combination with other materials in laboratory-tested wall and ceiling assemblies, gypsum board serves to effectively protect building elements from fire for prescribed time periods.
Preventing the transfer of unwanted sound to adjoining areas is a key consideration when designing a building, specifically when taking into account the intended activities of the occupants in the various parts of the building. Gypsum board wall and ceilings systems effectively help control sound and are used for sound isolation and control
Gypsum boards are used to construct strong, high quality walls and ceilings that offer excellent dimensional stability and durability. Surfaces created using gypsum boards are easily decorated and refinished.
Gypsum board is readily available and easy to apply. It is an inexpensive wall surfacing material that provides a fire resistant interior finish. Gypsum boards building systems can generally be installed at significantly lower labour costs than most alternate systems.
Gypsum boards satisfy a wide range of architectural requirements for design. Ease of application, performance, ease of repair, availability, and its adaptability to all forms of decoration combine to make gypsum board unmatched by any other surfacing product.
