Brio WF

General Information

Knauf Brio 18WF and 23WF are high quality composite flooring systems using gypsum fibreboard technology.  These boards can be installed and ready for foot traffic in a fraction of the time of traditional wet screeds.  The Brio WF is formed from 1100-1200kg/m³ gypsum fibre board with a 10mm acoustic resilient layer which is bonded to the underside of the board and formed from 250kg/m³ wood fibre for enhanced acoustic performance.

• Thickness: 28mm and 33mm total, respectively 
• Fixings: the fixings are the same as would be used for the non-WF Brio panels and do not penetrate into the wood fibre layer as they are purposely designed to be 1mm shorter than the panel thickness
• Impact resistant surface
• Fixed board edge for robustness
• Enhanced acoustic performance 
• Quick to install
• Able to receive floor finish after 24 hours

Application 

For use over solid substrates and where additional acoustic considerations are being made.

Compliance

• BS EN 15283-2

   

FAQs

• Can I use this over a pedestal system or over joists? 

No, the Brio boards are non-structural and as such must be used on a solid subsrate.  (For pedestal, joist and batten systems, see Knauf GIFAfloor high density floor panels.)

• Can I use over UFH? 

No, we do not recommend over this as the wood fibre (WF) layer will be detrimental to the performance; we would recommend using a suitable resilient layer beneath any UFH for acoustic purposes, and then using the standard Brio  18 or 23 on top of the UFH itself, to optimise performance.

• What is the weight of these? 

For the Brio 18WF: 22.3kg/m² (Brio: 19.8kg/m², WF: 2.5kg/m² ).

For the Brio 23WF: 27.8kg/m² (Brio: 25.3kg/m² , WF: 2.5kg/m² ).

• What loading are these suitable for? 

A 2.0kN point load (25 x 25mm), or 3kN area load.

• What do I use to cut this board? 

We recommend a diamond tipped blade on a circular saw with a dust extractor.  Details are available upon request.

• Do I need to fix the boards together? 

Yes.  To ensure a smooth finished surface, Knauf Brio Joint Adhesive and specialist Knauf Brio Screw fixings are required.  The screws ensure that the boards do not lift or move whilst the adhesive cures.

• Can I use vinyl over these boards? 

Yes, but to prepare the boards we advise that a thin layer [2mm] of latex screed or Knauf N410 is applied over the board surface first.
