3 Selector+ PLASTERBOARD SYSTEMS D Installation Details D1 General Installation and Fastening Sequence for Steel Studs The fi rst plasterboard sheet installed at a joint should be fi xed to the open side of a stud fl ange. Additional sheets are then installed in the direction toward the closed side of the stud web. When installing the first side, screw-fasten the plasterboard sheets to studs at edges only, as illustrated in Figure 1 (positions 1 and 2). Then, on the second side, fasten the edge (position 3) followed by intermediate studs (position 4). Return to the fi rst side and fasten sheets to previously unattached studs (position 5). 3 4 INCORRECT DIRECTION IN RELATION TO STUD Figure 2 - Incorrect Fastening Sequence CORRECT DIRECTION IN RELATION TO STUD Figure 1 - Correct Fastening Sequence Caution Avoid fixing Boral Plasterboard sheets in the direction from the closed side of the stud to the open side of the stud web (Figure 2). This will result in the fi rst sheet at a joint being incorrectly screwed to the fl ange on the closed side of the stud. The fl ange will then be free to defl ect when the next sheet is screwed to the open side (Figure 2). This can permanently bend the fl ange, resulting in a lipped joint. Bent flange Twisted stud Lipped Joint Lipped Joint Figure 3 - Effect of Incorrect Fastening Sequence If the stud is not supported fi rmly while the screws are driven, the stud can twist from square, also resulting in a lipped joint (Figure 3). Do not fix plasterboard sheets in the direction from the closed side of the stud to the open side of the stud web (Figure 2). Do not screw the first sheet at a joint to the flange at the closed side of a stud web. General D1 BORAL PLASTERBOARD February 2009 D1. 1

4 D1 General D Installation Details Selector+ PLASTERBOARD SYSTEMS» Installation and Fastening Sequence for Steel Studs Correct Installation The correct direction of sheet installation is in the direction from the open side of the stud to the closed side of the stud web (Figure 4). The fi rst sheet installed at a joint is screwed to the fl ange at the open side of the stud. The fl ange will initially defl ect then straighten as the screw pulls tight. Ensure that the stud is adequately supported to avoid twisting, and fully screw this sheet to the stud before continuing. The next sheet is now screwed to the fl ange at the closed side of the stud. The defl ection on this part of the fl ange is very small, and the previously installed sheet helps keep the assembly rigid during the installation of the second sheet. If fi xed correctly the result is a fl at joint with no lipping (Figure 5). The correct installation sequence is illustrated in Figure 5 below. Do fi x plasterboard sheets in the direction from the open side of the stud to the closed side of the stud (Figure 4). Do screw the fi rst sheet at a joint to the fl ange at the open side of a stud.

D is a double start, drill point, bugle head type D gypsum screw for fixing to steel gauges 0.80 to 2.00mm BMT. 5. L is a single start, needle point, bugle head type L gypsum screw for fixing plasterboard to plasterboard. 6. Screw designation given as (minimum screw gauge) - (threads per inch +1) x (minimum screw length). 7. For ease of construction with framing steel gauges of less than 0.8mm BMT use 30mm minimum screw length. 8. Correct screw length is critical when fastening to resilient furring channel to avoid acoustic bridging. 9. Nail lengths are minimums, however care is needed when selecting longer nails to avoid nail bending in hardwoods or popping of plasterboard with unseasoned timber. 10. For wall systems only.

7 Selector+ PLASTERBOARD SYSTEMS D Installation Details D2 Walls Wall Construction Notes 1. Steel stud wall systems are non load bearing unless noted otherwise. 2. Wall systems should not be used where conditions of constant excessive moisture or humidity are prevalent ie, in excess of 90% relative humidity. 3. Movement joints should be put at building construction joint locations. Control joints should be spaced at not more than 12 metre maximum centres in either direction. 4. Finish all joints with Boral Plasterboard jointing system, compromising perforated tape and jointing compound. 5. All approved fire rated penetrations must be installed and caulked in accordance with details provided in this manual. 6. Fire rated systems must be assembled strictly in accordance with relevant test reports, opinions, approved system details and specifications. 7. Steel Studs in fire rated partitions are not to be fastened to top and bottom tracks except boxed studs facing fire door openings, in which case the boxed studs are pop riveted to the tracks. 8. Steel wall framing to Rondo specifications or approved equivalent and spaced at 600mm centres maximum. 9. Components must not be used if fractured or damaged. 10. Butt joints to be backed by stud or nogging for fire rated systems. 11. Mid span nogging is recommended for erection purposes for steel stud walls greater than 3600mm. 12. Timber stud framing to AS1684, relevant Australian Standards and spaced at 600mm centres maximum. 13. Fire rated timber systems shall be read in conjunction with Timber Charfactor Tables in Section C3 of this manual. D2 Walls BORAL PLASTERBOARD February 2009 D2. 1
