Product Summary

Overlay floating floor system for use over timber sub-floors where the existing timber deck remains. Monarfloor Deck 18 can be used on steel frame floors over a sub-floor of chipboard and gypsum based board.

Monarfloor Deck 18

The simplest way of improving the airborne and impact sound performance of an existing floor is to overlay the floor with an isolating layer and new hard wearing surface.

If height loss is more of a concern than airborne performance, then consider Monarfloor Deck 9 which benefits from only adding 17mm to the floor-level. If you are looking at removing the existing floorboard, or are working on a new build, then consider the Monarfloor Trideck which is an excellent all in one acoustic solution.

Product Application

Monarfloor systems can be used to upgrade existing floors with particular emphasis on improving the impact sound qualities. Monarfloor systems are regularly used in regulation Part E work. When used in conjunction with mineral wool and resilient bars in the ceiling below monarfloor systems will exceed the levels required for regulation Part E.

Features & Benefits

  • Applications for existing timber floors.
  • Supports floor loadings as defined in BS EN 1991-1-1:2002 +A1 2010 (Eurocode 1) which stipulates floor loading of 2 kN.
  • BBA Certified.
  • Superior performance – the recycled Low Resonance Acoustic Chip (LRAC) foam used has excellent impact improvement characteristics and superior stability within a single layer.
  • Flame retardant – all LRAC foam used in Monarfloor® systems is flame retardant.
  • Exceeds the performance requirements of ADE.
  • Dimensions: 26mm x 600mm x 2400mm
  • Weight: 22.2kg per sheet (15.4kg per m2)

Instructions for use

Monarfloor systems are regularly used in regulation E work. When used in conjunction with mineral wool and resilient bars in the ceiling below, Monarfloor systems will exceed the levels required for regulation E.

Monarfloor Deck 18 platform floor / floating floor (FFT5) system on a timber sub-floor with a resilient bar system:

Diagram Key

  1. Acoustic Flanking Band – reduces impact vibration transmission via party and flanking walls and assists in reducing airborne sound paths.
  2. 100mm 45kg/m³ insulation.
  3. 22kg/m² double boarded ceiling on resilient bars perpendicular to joist direction
  4. Monarfloor® Deck 18 system on existing timber floor (subject to condition) or new 18mm chipboard deck on 200 x 50mm timber joists.

Installation at a glance

  • Flank all perimeter with Monarfloor® Flanking Band.
  • Level the sub-floor to the required tolerance.
  • Lay Monarfloor® Deck 18 platform floor / floating floor (FFT5) system over existing sub-floor in a broken bond pattern, applying Monarfloor® Adhesive to all tongue and groove panel joints.
  • Install skirting and trim off excess Flanking Band.

Tools & equipment required

  • 1 litre of Monarfloor® Acoustics Adhesive for every 21.5m2 of deck (approx). Note: Adhesive should be applied in well ventilated rooms.
  • 1 linear metre of Monarfloor® Flanking Band for every 1m2 of flooring.
  • Utility knife and straight edge.
  • Joinery hand/power tools.
  • Check sub-floor is suitably prepared
  • Ensure the surfaces are structurally sound, clean and dry.
  • All internal partitions should be installed and built of the sub-floor.
  • Kitchens and bathrooms should also be built of the sub-floor (see Monarfloor Generic Kitchen & Bathroom Detail Drawings).
  • Ensure the correct mineral wool insulation has been packed tightly between the floor joists.

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.

Care of materials

Materials must be kept in a dry storage area at all times.

Working safely

  • Working on any building site can be a hazardous activity. Only suitable persons having appropriate competence, training and physical fitness should be allowed onsite.
  • Personal Protective Equipment (PPE) must be worn at all times.
