AcoustaMat™ is an innovative product that uses specially engineered recycled rubber underlays to meet the acoustical requirements of all common construction and installation methods. It can be used as excellent, eco-friendly and cost-effective underlay to timbers, ceramic tiles, vinyl flooring, carpets or floor lamination.

For high-rise units, multi-storey townhouses and homes. Suitable for new and old buildings requiring impact sound insulation for the installation of timber, laminate, carpet, plank vinyl/vinyl over Masonite or ceramic floors. Can be installed on timber and concrete sub-bases. 

  • Material: Polymerically bound black recycled rubber
  • Appearance: Black
  • Thickness: 3.0mm & 5.0mm
  • Width: 1.2m 
Key Features
  • Unique sound impact attenuating properties
  • Permanent resilient elasticity 
  • High temperature resistance
  • Premium recycled rubber
  • Rubber is an excellent material for noise reduction and vibration control due to its high density, regular consistency and elasticity. These physical characteristics aid in reducing sound transfer by evenly absorbing sound across the material.
