Installation Instructions for: Wall System 1
Instructions for installing Wall System 1.
- All skirting, coving and electrical points should be removed. These can all be reinstated once the wall is finished.
Fixing Wall System 1
- Before the installation commences we recommend you lift some of the floor boards and inspect the wall area below the floor level. Dense Fibre Matting (DFM) 100mm/80kgm³ should be used to fill these areas as necessary, this will help reduce flanking noise. Replace the floor boards as these will act as a solid base.
- Erect the stud wall using timber or metal stud work, the depth of the stud should be a minimum of 50mm to incorporate the DFM acoustic insulation. The wall can be erected against the existing wall, try to avoid fixing into the wall as this will reduce sound transferring along the screws. Leaving a 25mm gap between the existing wall and the acoustic wall will enhance the soundproofing of this acoustic wall system. Fix the new wall to the floor, ceiling and the return walls. Centre the studs between 595-600mm to accommodate the 600mm wide DFM slabs.
- The DFM should be pushed in to the cavity created by the battens, the material will friction fit and should not need any fixings to hold it in place. The DFM can be cut with a hand saw or a knife when necessary, ensure that no gaps are left when installing the DFM, use off cuts in any areas that may need filling.
- The soundbreaker bars can now be fitted to the wall. Starting from the bottom of the wall fix the first bar at right angles to the battens using screws. Fix the screws through the pre-drilled holes on the bars ensuring the wide flange is facing up and the section of pre-drilled holes is at the bottom, flat to the battens. Repeat this along the full length of the wall. Bars can be cut to length using tin snips or a hack saw, if you need to join any bars together you can over lap them. Repeat this process up the wall with a gap of 600m between the bars, each board should be attached to three Soundbreaker Bars. NOTE: bars should be spaced to allow the top of the first layer of boards and the bottom of the top row of boards to share one bar. We recommend bars spaced at around 600mm centres to achieve this.
- Now the wall should look like a chess board with battens running one way and the bars running at right angles. You can now fix the boards to the soundbreaker bars; boards should be screwed directly into the bars through the wide corrugated section of the bar, do not screw in to the battens behind the bars as this will reduce there effectiveness. You do not need to pre-drill holes, the screws will go through the board and puncture the bar, and this will hold the boards in place. We recommend that you use a minimum of 12 screws per board (3 rows of 4). The boards can be cut to size with either a hand saw or equivalent. Please ensure that you seal all joints with a suitable acoustic sealant. An extra layer of 12.5mm soundblock board can be applied over the top if required. Once completed the wall can be plastered or the edge’s can be taped and filled.
