15 mm thick acoustic barrier mat with a resilient chip foam core. It contains three acoustic layers that combine to massively reduce both impact and airborne noise.

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.

Features and benefits:

  • Suitable for all final finishes on timber floors.
  • Easy to cut, trim and shape in easy to handle 600mm x 1200 mm sheets.
  • Suitable for conversion projects.
