High Performance Acoustic Floor System
Trim Defender 21 is a nominal 21mm thick, high performance, acoustic floating floor board designed for laying over 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. Trim Defender 21 damps vibration and attenuates both airborne sound and impact noise passing through floors. The moisture-resistant upper surface means the same acoustic flooring can be used throughout the building, including kitchens and bathrooms. The acoustic felt on the underside will contour over minor irregularities in the surface of the floor being treated.

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.
