Definition of GWB

GWB, or Gypsum Wallboard, is a type of building material used for interior wall surfaces in residential and commercial construction. It is commonly referred to as drywall or plasterboard. GWB consists of a gypsum core, which provides fire resistance, sandwiched between two layers of paper or fiberglass mats. These layers give the GWB panel its durability and stability.

The gypsum core in GWB is made from a naturally occurring mineral called gypsum, which is processed into a fine powder and then mixed with water. When the gypsum powder is hydrated, it forms a paste-like substance that is poured onto a continuous moving sheet of paper or fiberglass. As the sheet moves along the production line, the gypsum paste evenly spreads across the surface, and another layer of paper or fiberglass is added on top. The result is a panel of GWB with a consistent thickness and smooth finish.

GWB panels come in various sizes and thicknesses, with the most common thicknesses being 1/2 inch and 5/8 inch. The panels are typically available in standard sizes such as 4 feet by 8 feet, although custom sizes can also be manufactured to suit specific project requirements. The edges of GWB panels are either tapered or squared, with the tapered edges allowing for smoother transitions between panels and easier finishing.

Overall, GWB is a versatile and cost-effective building material that has revolutionized the construction industry. Its ease of installation, durability, fire resistance, and cost efficiencies have made it a popular choice for creating interior walls and ceilings.
