32mm JCW Acoustic Deck 32 - Chipboard based Acoustic Overlay Board

32mm JCW Acoustic Deck 32 is a chipboard based acoustic overlay board for shallow platform floor systems, for use with robust standard detail concrete floor constructions and for use with PCT timber floor constructions. It is 18mm t&g chipboard laminated to a 10mm acoustic resilient foam layer.

CHARACTERISTICS

• An ideal solution where construction heights are a problem,
• Easy to install,
• Suitable for for new flooring systems or upgrades to existing separating floors,
• An economical product for Conversion projects
• Offers good impact sound improvement,
• Deck ready for final floor finish e.g.laminates, carpets and carpet tiles, Overlaid onto flat timber or concrete floors.

                

APPLICATION

• New build
• Refurbishments
• Domestic upgrade
• On concrete and timber floors

INSTALLATION

• The boards must be dry and acclimatised at least 24 hours prior to installation, this will minimise any expansion or contraction after installation.
• Ensure that the floor surface is flat, dry, and free from all debris.
• Ensure that the wall surfaces are prepared - plaster skimmed or plaster boarded down to the level of the sub-deck.
• Ensure there are no gaps at wall edges.
• Apply 5mm foam flat wall JCW Perimeter Edging Strip or L shaped strips to the base of all perimeter walls allowing approximately 15mm excess foam above the finished acoustic board height. This can later be folded down on top of the acoustic floor surface to isolate the skirting boards.
• Remove any tongues at the wall edges, then cut & scribe the first corner board into place and butt up to the Edging Strip. Do not compress the JCW Perimeter Edging Strip.
• Ensure all T&G board joints must be fully adhesive bonded using a recommended adhesive.
• Proceed with the second and successive rows ensuring that all board joints are staggered. The last row of boards will require accurate cutting & scribing to butt up to the wall.
• Any minor gaps between the JCW Perimeter Edging Strip and the acoustic board must be filled with JCW Acoustic Sealant/Mastic.
• It is imperative that the JCW Perimeter Edging Strip is not compressed in order to maintain acoustic isolation and an allowance for expansion.
• At the door threshold leave a 5mm gap between the adjoining acoustic boards and fill with JCW Acoustic Sealant. If the sub-floor at the doorways is not flat, the acoustic boards may require additional base support to reduce compressive joint movement. Additionally the surface joints could be sanded up to 5mm to level if required.
• The finished floor should not be walked on for a period of up to 24 hours to allow the adhesive to cure undisturbed.
• Ensure that the board joint adhesive has fully cured prior to overlaying any final floor covering.
