Definitions

• the present invention relates to the field of timber frame partitions that have improved acoustic performance, in particular to timber frame partitions having plasterboard cladding.
• the present invention may provide a partition for a building structure, the partition comprising a support frame and at least one plasterboard affixed to the support frame by means of a plurality of screws, wherein:
• the plasterboard comprises a gypsum matrix having fibres embedded therein in an amount of at least 1 wt% relative to the gypsum, the gypsum matrix further comprising a polymeric additive that is present in an amount of at least 1 wt% relative to the gypsum;
• the support frame comprises a plurality of elongate timber members; and the average spacing between nearest-neighbour screws is greater than 400mm.
• the average spacing between nearest-neighbour screws is greater than 500mm, preferably greater than 550mm.
• At least a portion of the screws is distributed around the perimeter of the plasterboard, and engages with timber members disposed at the perimeter of the
• At least one screw is located in a central region of the plasterboard, displaced from the perimeter of the plasterboard, and engages with a timber member disposed along a central region of the plasterboard, wherein the average distance between nearest-neighbour screws disposed along the central region of the plasterboard is greater than 600mm.
• the average distance between nearest-neighbour screws disposed along the central region of the plasterboard is greater than 800mm, preferably greater than 1000mm.
• the fibres are present in the gypsum matrix in an amount of at least 3 wt% relative to the gypsum, more preferably at least 5wt%.
• the polymeric additive is present in an amount of at least 3 wt% relative to the gypsum, more preferably at least 5wt%.
• the fibres are glass fibres.
• the polymeric additive is one of starch or polyvinyl acetate.
• the plasterboard is in direct contact with the support frame, that is, no adhesive is used to bond the plasterboard to the support frame.
• the plasterboard may comprise a gypsum core having a liner on one or both faces. In that case, the liner is typically in direct contact with the support frame.
• Figure 1 shows a schematic elevation view of an embodiment of a partition according to the first aspect of the present invention.
• the cladding is rendered transparent to show the detail of the frame
• Figure 2 shows a schematic elevation view of a partition according to an illustrative example of the present invention; the cladding is rendered transparent to show the detail of the frame.
• Figure 3 is a graph showing the results of acoustic testing for Example 1 and Comparative Example 1.
• test specimen was constructed from a timber frame, insulation and a gypsum
• the timber frame consisted of 63mm x 38mm head and base rails connected by 63mm x 38mm timber studs extending therebetween. The distance between the head and base rails was 2400mm, while the timber studs were spaced at 600mm intervals. 65 mm insulation was placed within the stud cavity.
• the stucco slurry used to prepare the boards had a water gauge (that is, a weight ratio of water to stucco) of 0.7.
• the board had a thickness of 12.5mm and a weight of about 12 kg/m 2 .
• the board dimensions were 1200mm x 2400mm.
• the boards were fixed to the frame as shown in Figure 1. Referring to Figure 1 , the frame comprised a top rail 10 and a bottom rail 12, two lateral studs 14a, b and a central stud 16.
• the board 20 is fixed to the frame by means of screws 22 that are spaced at 600mm intervals along the top and bottom rails 10,12 and the lateral studs 14a,b, and that are spaced at 1200mm intervals along the central stud 16.
