An acoustic floor system developed from an industrial product originally designed to greatly diminish the transfer of plant machinery noise through floors.

The laminated 'sandwich' composition provides maximum performance for minimum thickness and combines excellent sound insulation with all the qualities of a good carpet underlay.

Consists of a 10 mm layer of chipfoam bonded between two layers of 7.5 kg/m² mineral loaded acoustic barrier matting. The base layer of barrier mat seals and dampens the sound coming through the floor; the isolated top layer of soundproofing mat blocks the sound in both directions, and the chipfoam core dramatically reduces impact noise transfer. Made from 100% recycled materials.


  • Impact and airborne noise reduction for floors.
  • High footfall and airborne noise reduction under carpet.
  • Handy sized panels; easy to cut, shape and install.
  • Suitable for concrete and timber floors.
  • Overall thickness just 15 mm to minimise elevation of floor level.
  • Can be used with other products to meet new building regulations.
