Suitable for all final finishes on timber floors.


A premium resilient overlay matting containing three acoustic layers that combine to massively reduce both impact and airborne noise.

Features and benefits:

  • 15 mm thick acoustic barrier mat with a resilient chip foam core.
  • It is manufactured using an acoustic foam resilient layer sandwiched between two layers of weight enhanced acoustic barrier mat. The acoustic foam does not harden or crumble, unlike the Class O foam normally found in these applications.
  • Ideal upgrade product for Impact and Airborne noise problems in domestic properties where heights are restricted and access to ceiling in property below may not be an option.
  • Easy to cut, trim and shape in easy to handle 600 x 1200 mm sheets.
  • Suitable for conversion projects.
