Acoustic overlay flooring product suitable for use on new and existing timber floors. The substrate layers of moisture-resistant MDF and cement particle board are separated by visco-elastic sound damping strips. The underside incorporates a resilient layer of acoustic felt which provides mechanical isolation from the existing floor structure. REDUC® Micro 21 is 21mm thick and is designed to damp vibration and attenuate both airborne sound and impact noise passing through floors whilst having minimal impact upon room height.

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.
