SUNHOUSE 4x8' Gypsum Plaster Board Drywall Board Gypsum Board For Ceiling
Description of Plaster Board
Ordinary gypsum board, also known as drywall or wall board, is a common building material used for walls and ceilings in the construction industry. It consists of a plaster core, sandwiched between two layers of thick paper or fiberglass bedding. The gypsum core is made from a mixture of gypsum powder, water and additives, which are then poured on paper or fiberglass mats to form plates.
The standard size of drywall is usually 4 feet wide, 8 feet long, and the thickness varies from 1 / 4 inches to 5 / 8 inches. However, there are also larger sizes available for commercial applications. Gypsum board is more popular than traditional plaster because it is easier and faster to install and requires less labor and time. It is also a cost-effective material, making it a popular option for both residential and commercial construction projects.
Features of Plaster Board
1. Fire resistance
Since gypsum itself is a fire resistant material, gypsum plasterboard can also be fire resistant for up to four hours. The reason behind this is the presence of water in gypsum offerings. When water comes in contact with fire, it starts evaporating. It helps the board to form a protective layer which helps to prevent the fire from spreading over a period of time.
2. Non-combustible
When a gypsum board comes in contact with fire, it starts the process called calcination. Calcination is the process by which the board dehydrates, helping it to form an additional layer. It makes the wall non-combustible for several hours and always remains at room temperature.
3.Damp Proof / Waterproof Gypsum Board
The green appearance is mainly made of building gypsum with an appropriate amount of fiber reinforcing agent and waterproof additives.
Suitable for wet and semi exposed areas, with a tileable surface.
Scope of application: kitchen, bathroom, laundry, garage, bathroom, laundry, humid environment, etc.
4. Acoustic properties
Gypsum board has an inherent degree of acoustic insulation. These are more effective compared to conventional walls of the same thickness. This is because they contain sound interruptions and reduce reverberation.
For example, a plasterboard of around 60 mm is as effective as an 85 mm masonry wall in terms of sound insulation. Users can also choose to use acoustic gypsum board to further improve performance.
