Karma Acoustic OverlayPlus 26 is an overlay board intended to be laid above a timber deck to reduce impact and airborne sound. It consists of 18mm T&G4, P5, chipboard laminated to a 8mm recycled foam resilient layer and provides superior impact performance than Karma Acoustic Overlay 23.
CHARACTERISTICS
- Quick and easy to install, offering savings in labour,
- Non-load bearing partitions can be built off the floating floor,
- Minimal height increase offering savings in brickwork and foundations,
- Moisture resistant,
- Tongued and grooved chipboard, laminated to a resilient foam layer,
- Sustainable product made from recycled materials,
- Excellent performance offered for impact attenuation
- Cost-effective solution
- Versatile can be finished with all types of floor finish
APPLICATION
- New build apartments, hotels, student accommodation and houses with timber joist floors,
- Refurbishment projects where height restrictions exist but reliable performance is still required
INSTALLATION
- The building should be substantially watertight prior to installation ofKarma Acoustic 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 Karma Acoustic OverlayPlus
- Prior to installing the Karma Acoustic OverlayPlus attach Karma Acoustic Perimeter Strip to the base of the walls in all perimeter areas. Offer up the Karma Acoustic OverlayPlus board so that it butts up to the Karma Acoustic Perimeter Strip without compressing it too much as to compromise the acoustic integrity of the tape.
- When laying Karma Acoustic OverlayPlus, begin installation in the furthest corners of the room and work back towards door openings.
- Cut tongues off joints in the Karma Acoustic OverlayPlus so that a square edge abuts the previously fitted Karma Acoustic Perimeter Strip
- Lay Karma Acoustic OverlayPlus in a brick bond 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 Karma Acoustic OverlayPlus and the Karma Acoustic Perimeter Strip with acoustic sealant.
- Do not screw fix into the Karma Acoustic floor other than as a temporary measure whilst adhesive in the T&G joints is setting.
