Monarfloor Tri-Deck

Monarfloor Tri-Deck is designed to reduce sound transmission through timber floors in conversion or refurb projects where the existing timber floor will be removed but access to work on the ceilings below are restricted. When installed as part of a complete sound reduction specification it enables a timber floor to meet Part E (2003) of the building regulations.

Tri-Deck consists of 22mm V313 P5 moisture resistant chipboard bonded to 8mm layer of LRAC foam bonded to a further 5mm foam rubber

Installation of Monarfloor Tri-Deck on timber joists	Tri-Deck over timber joists

Monarfloor Tn-Deck should be laid directly onto the joists, in broken bond with all joints glued. Guidance should be sought if you are in any doubt as to the quality or density of the surrounding structural elements before proceeding.

Tiling on top of Monarfloor

We advise you follow the guidance issued by the Tile Association in dealing with floating floors, which is:

• Adhesives and grouts must be suitable for floating floors. There are various systems depending on the individual manufacturers detailing.
• Proprietary tile boards or ply, can be overlaid to provide additional water tightness, and or stiffen the floating floor. These must be bonded.
• Tiles should ideally be porcelain. We do not advise thick heavy tiles such as marble etc as they are more susceptible to fracture.
• Tile format must be kept as small as possible (600 x 600mm max). We would advise 450mm x 450mm.

You should also speak to the adhesive manufacturer that is being used as they all have specific detailing to their own products.
