    Abstract: A gypsum board has two opposed faces, and a fibrous mat being embedded in one of the faces of the board. The fibrous mat comprises fibres that are bound by a polymeric binder. The length of the fibres is greater than 20 mm, and the diameter is greater than 14 micron. The polymeric binder is substantially formaldehyde-free. The fibrous mat achieves fire resistance in the gypsum board without the need to incorporate flame retardants into the binder, as well as providing flexural strength.

    Abstract: A method of forming a gypsum based product is disclosed. The method comprises the steps of: calcining a mixture of water and gypsum under conditions of raised temperature and pressure within a vessel to produce an alpha-hemihydrate slurry therein; passing the alpha-hemihydrate slurry from the vessel to a mixer for mixing with additional water to produce a settable slurry, which is arranged to set to form the gypsum based product.
