Staggered stud acoustic partition system

Transcription

1 GypWall STAGGERED GypWall STAGGERED Staggered stud acoustic partition system GypWall STAGGERED is a nonloadbearing metal stud partition which provides very high levels of sound insulation. In public and commercial developments it can be used for space division within critical areas of offices, hotels, schools, hospitals, recreational complexes, shops, and conference centres. In refurbishment work on residential units it can be used as a sound resisting, space saving partition between dwellings. 66

6 Technical support: T F E bgtechnical.enquiries@bpb.com Construction tips The following points should be considered in addition to the construction tips for GypWall CLASSIC Estimated construction time m.m / man hour (single layer partition) or.m - m / man hour (double layer partition) ready for finishing GypLyner GypWall STAGGERED UNIVERSAL To maintain the high levels of sound insulation it is essential that services, fixtures, etc, do not bridge the two sets of stud linings Use special detailing at deflection heads (see Junction details deflection) to maintain acoustic performance Openings require careful detailing to minimise loss of acoustic performance Specialist heavy acoustic doorsets may require additional support 7

7 GypWall STAGGERED CLASSIC Installation Determine and mark the wall position and make allowance for openings. Fix Gypframe Floor & Ceiling Channel along centre line of floor and ceiling at 600mm centres with suitable fixings. On uneven floors a timber sole plate, 8mm x width of channel, may be required. On new concrete or screeding, consider installing a damp proof membrane. 8mm channels require two rows of staggered fixings (600mm centres in each row). Fix Gypframe C Studs to the abutting wall at 600mm centres. 6mm studs require two rows of staggered fixings (600mm centres in each row). Cut Gypframe I Studs 6mm short of the floor to ceiling height using a chop saw / circular saw. Insert a Gypframe Spacer Clip top and bottom of the Gypframe 'I' Stud. Use Gypframe SC Spacer Clips for engaging Gypframe 60 I 70 'I' Studs and Gypframe SC Spacer Clips for engaging Gypframe 9 I 90 'I' Studs. 7

8 Technical support: T F E bgtechnical.enquiries@bpb.com GypLyner GypWall STAGGERED UNIVERSAL 6 Use the clip as the pivot point when turning the stud to minimise sliding. Fit Gypframe 'I' Studs vertically within the Gypframe Floor & Ceiling Channel at 00mm centres (Gypframe 'C' Studs to abutments see Junction detail ). Alternate clips on either side of the Gypframe 'I' Stud to give the staggered stud framework. Fit the specified thickness of Isover APR 00 insulation in the cavity. Apply Gyproc Sealant as a continuous bead to the perimeter of the framing on both sides before boarding commences, to ensure acoustic performance. 7

9 GypWall STAGGERED CLASSIC Gypframe GFS Fixing Strap 7 Board fixing Screw-fix boards to alternate studs (which are in contact with board) at 00mm centres using Gyproc Jack-Point Screws. Reduce centres to 00mm at external angles. Under-layer boards do not require centre fixings. Cut and fix the initial second layer board as appropriate, so that subsequent board joints are staggered. 8 Gypframe GFS Fixing Strap located to support horizontal joints of outer layer boards. 7
