Plasterboard is often also referred to as drywall, wallboard or gypsum board. Unlike other sheet-like building products such as plywood, hardboard and fiberboard, they have a non-combustible core and a paper coating. When joints and fixing heads are covered with joint compound, plasterboard becomes a continuous surface suitable for most types of interior decoration.
Smooth gypsum boards have an ivory-colored surface and a gray backing. It is made from building plaster as the main raw material, to which an appropriate amount of lightweight materials, fiber reinforcements and additives are mixed and bonded with paper.
It is light, stable and has excellent thermal and sound insulation properties.
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.
