Prior to commencement, check method of plasterboard fixing to existing masonry wall is via daubs of adhesive. Plasterboard fixed on battens/furring channel will need to be removed prior to applying NeighbourZone™ system. In this case, visually check the surface of exposed block walling for any cracks/unsealed penetrations and seal appropriately with Firesound® sealant. If the majority of the wall surface is in poor condition, bag or render the entire surface prior to applying the acoustic upgrade.
Remove existing cornice and skirting.
Cut back any carpet sufficient to allow base of plasterboard in NeighbourZone™ system to be sealed against concrete slab or timber floor.
Cut-back nominally 300mm of ceiling if NeighbourZone™ system is required to extend through to underside of floor/roof above.3 (Note: do not cut-back if ceiling is fire rated).
If required, remove existing GPO’s and extend electric wiring so that fire-rating of existing wall is not downgraded.
Install furring channels vertically at max. 600mm centres, and horizontally at top and bottom of the wall.
Install Insulation Solutions 50mm thick Sonobatt Type 1 glasswool batts (32 kg/m3 density) tight between furring channels.
Fasten each layer of Boral SoundStop® plasterboard to furring channels with screws at 400mm max. centres in the field of the board and at 300mm max. centres on sheet edges. Leave a nom. 6mm gap around perimeter and fill with FireSound sealant (the first layer of SoundStop® plasterboard can sit on a nom. 6mm closed cell acoustic foam in lieu of sealant).
If GPO’s are required, box in or use proprietary acoustically rated GPO such as HPM acoustic/fire box.
