Structural and overlay acoustic flooring product suitable for use on new and existing timber floors. It comprises two layers of chipboard, the upper layer being moisture-resistant, separated by visco-elastic sound damping strips with an acoustic felt on the underside. REDUC® Foundation 39 is designed to damp vibration and attenuate airborne and impact noise passing through floors.

Tested floor – Foundation 39 laid onto joists with 45kg/m3 insulation continuously between 225mm x 50mm timber joists. Resilient Bars to be directly fixed to the ceiling joists to support 2 layers of 12.5mm acoustic plasterboard.
Flanking Transmission
The performance figures quoted above are based on test results for 225mm timber floors using the components indicated and can only be expected if the building design and construction has followed good practice to ensure all potential flanking paths have been eliminated. In order for wall and floor constructions to be fully effective, extreme
care should be taken to correctly detail the junctions between the separating wall or floor and the associated elements such as external walls and any penetrations. If junctions are not detailed correctly, the acoustic performance will be limited and Building Regulation requirements may not be achieved in practice.
