What is Gypsum Board?

Gypsum board, commonly known as drywall, Gypsum Board Installation is the technical product name used by manufacturers for a specific board with a gypsum core and a paper facing.

Gypsum board is the premier building material for wall, ceiling, and partition systems in residential, institutional, and commercial structures and is designed to provide a monolithic surface when joints and fastener heads are covered with a joint treatment system.

One principal advantage of gypsum board over plywood, hardboard, and fiberboard is its strong fire resistance. Gypsum products also provide sound control, economy, versatility, quality, and convenience.

How to make Gypsum Board?

To produce gypsum board,calcined gypsum is mixed with water and additives to form a slurry which is fed between continuous layers of paper on a board machine.

As the board moves down a conveyer line,the calcium sulfate recrystallizes or rehydrates,reverting to its original rock state.

The paper is then cut to length and conveyed through dryers to remove any free moisture.

Gypsum manufacturers also rely increasingly on "synthetic" gypsum as an effective alternative gypsum ore.
