Table 1: Components for Metal Stud Partitions Insulation If insulation is specified, use GTEC Insulation Hold strips, screw-fixed or crimped to the studs 150mm from the partition head and at 1200mm vertical centres down the partition. Movement control joints 30 minute fire rated two layers 15mm GTEC Fire Board 60 minute fire rated two layers 15mm GTEC Fire Board rock mineral wool density 60 kg/m 2 GTEC C Stud Plasterboard as specified GTEC C Stud GTEC Movement Control Joint GTEC C Stud 15mm GTEC Fire Board GTEC Movement Control Joint Movement control joints may be required to relieve normal structural movement without loading the partition. Movement control joints are required in partitions at intervals not exceeding 10m, where the partition crosses or abuts a structural movement joint, and where partitions of dissimilar materials meet in the same plane. At movement joints, leave a 12.5mm gap in the GTEC U Tracks at head and base. Fix a GTEC C Stud on one side, 10mm from the gap, and line the web with two layers of 15mm GTEC Fire Board. Place another stud, web facing web on the opposite side of the gap, as shown. Board the partition, leaving a continuous 12.5mm gap between boards along the line of the movement joint. Cut GTEC Movement Control Joint to length; butt joint lengths end to end where necessary. Attach to the plasterboard surface with 13mm stainless steel staples at 150mm centres. Apply GTEC Joint Filler or GTEC Allset Xtra in two coats, feathering out the edges of the second coat. After finishing, remove the masking strip from the centre of the joint.

The knock-outs in the studs can be used for routing electrical and other small services. Cables should be protected by conduit or other suitable precautions taken to prevent abrasion when they pass through the metal frame. THE INSTALLATION HANDBOOK 2008 27
