These boards are fire-resistant owing to the presence of gypsum which is calcinated. In the calcination process, gypsum is exposed to high heat that makes the water present in it turn into steam. Gypsum contains a large amount of water in crystal form. When the gypsum comes in contact with fire, the water in it vaporizes. Even if the whole water vaporizes, gypsum will not burn. Thus it protects the material which is bonded with it. Paper that is used in these boards is made up of recycled paper and can of two types.

• Manufacturing process: Gypsum board manufacturers mix or blends the plaster or gypsum with the fiber like paper, foaming agent, plasticizer, starch, EDTA, various additives that can reduce the mildew. The mixture is made to increase the fire resistance of the board and make it waterproof. The gypsum when comes in contact with moisture, it turns into a paste. The board is made by supplementing this mixture between the two sheets of paper. Then the edges are given shape and their finishing is done. After that, the board is cut into the standard size. This is then dried to make it strong to be used. For drying, they are kept in the chambers where the natural gas is used to dry them up. This removes the excess moisture from the boards.
