    Basic guidance notes for installation of JCW Acoustic Decking

    - All acoustic panels are laid as a floating floor (i.e. no mechanical fixings). The boards must be dry and acclimatised at least 24 hours prior to installation, this will minimise any expansion or contraction after installation.

    - The substrate or joists should be flat, dry, and free from all debris. Acoustic boards are best laid towards the end of the project to protect from general trades, high floor loadings and moisture leading to expansion.

    - The floor area/s to be overlaid should be carefully planned prior to commencing installation to minimise wastage. There are two overlay board types; 1) Non-Structural onto an existing sub floor. 2) Structural for Direct to Joist. The boards must be laid on to flat or levelled joists in the opposite direction of the joists. Direct to Joist boards can also be laid onto an existing sub-floor.

    - Ensure that the wall surfaces are prepared (plaster skimmed or plaster boarded down to the level of the sub-deck). Any gaps will facilitate the unwanted transmission of sound via the wall edges.

    Remove any tongues at the wall edges, then cut & scribe the first corner board into place and butt up to (do not compress the JCW Perimeter Edging Strip) the Edging Strip. 

    At doorways: the acoustic floor should not be continuous with adjoining areas. At the door threshold leave a 5mm gap between the adjoining acoustic boards and fill with JCW Acoustic Sealant. This action will ensure that the acoustic integrity is maintained within the room that is being Sound Tested. 

    - The finished floor should not be walked on for a period of up to 24 hours to allow the adhesive to cure undisturbed. NOTE; PVA adhesive will not cure in temperatures below 5˚ Celsius. Ensure that the board joint adhesive has fully cured prior to overlaying any final floor covering.

    - Any penetrations through the acoustic floor and beneath the separating ceiling must be correctly detailed and dealt with on a site by site basis.
