    Abstract: A method for continuously forming gypsum-based panels of high fixing strength comprises the steps of: • forming a mixture comprising stucco, non-pregelatinized migratory starch, glass fibre, fluidizer and water; • casting the mixture in a continuous band; • maintaining the band under conditions sufficient for the stucco to form an interlocking matrix of set gypsum; • cutting the band to form one or more wet panel precursors; and • drying the wet panel precursor to form one or more gypsum-based panels. • The weight ratio of water to stucco in the mixture is less than 0.7; • the stucco is present in the mixture in an amount of over 60 wt% relative to the total solids content of the mixture; • the starch is present in the mixture in an amount of over 3 wt% relative to the the stucco; • the glass fibre is present in the mixture in an amount of over 1 wt% relative to the stucco; • the fluidizer is is present in the mixture in an amount of at least 0,1 wt% relative to the stucco; and the density of the gypsum-based panel is greater than 700 kg/m.

    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 connector 1 for connecting together first and second elongate frame members 28, 23 of a stud wall. The first member 28 comprises an axially extending channel and the second member 23 has a channelled longitudinally extending profiled surface 27. The connector has a first elongate end 20 adapted to slidably fit into the channel at one end of the first frame member 28 and a second end 21 having a ribbed distal end face 22 which comprises a profile which is complementary to the channelled surface of the second frame member. In use, the distal end face of the connector 1 is butted up against and comes into complementary engagement with the channelled surface of the second frame member 23. A screw 30 holds the connector 1 against the profiled surface of the second member 23 to form an L-shaped structure which forms two sides of the desired frame.
