TECHNICAL INSTALLATION GUIDE FOR ATTENU8 OVERLAYPLUS ON A TIMBER FLOOR
- The building should be substantially watertight prior to installation of attenu8 OverlayPlus
- Insert 100mm x 45kg/m3 insulation between the floor joists. If being pushed in from below, cut the insulation slabs over size to ensure a tight fit. Use off cuts to fill gaps. Some, if not all floorboards may need to be lifted temporarily if the 100mm insulation is being pushed into the floor void from above.
- Floorboards or new chipboard flooring should be clean, level, free of debris and securely fixed to the floor joists prior to installation of attenu8 OverlayPlus.
- All internal walls should be built prior to installation of attenu8 OverlayPlus.
- Prior to installing the OverlayPlus attach acoustic isolation tape to the base of the walls in all perimeter areas. Offer up the OverlayPlus board so that it butts up to the acoustic isolation tape without compressing it too much as to compromise the acoustic integrity of the tape.
- When laying attenu8 OverlayPlus, begin installation in the furthest corners of the room and work back towards door openings.
- Cut tongues off joints in the OverlayPlus so that a square edge abuts the previously fitted acoustic isolation tape.
- Lay attenu8 OverlayPlus in a brickbond pattern across the floor.
- Use plenty of PVA adhesive in the T&G joints of the panels.
- Fill any gaps between the edge of the attenu8 OverlayPlus and the acoustic isolation tape with acoustic sealant.
DO NOT SCREW FIX INTO THE ATTENU8 FLOOR OTHER THAN AS A
