A fully recycled rubber underlay designed for use with both soft and hard flooring, such as engineered timber, laminate, stone flooring and carpet. It is designed to absorb footfall noise and increase living standards within the construction, whether in residential or commercial applications.

The material also has zero ozone depleting potential (OPD) and zero global warming potential (GWP). The specially selected rubber particles and fibres are designed to give excellent resilience yet giving the upmost compressive strength.


  • Easy to install.
  • Remains continually elastic.
  • Fully recycled.
  • Cost effective.
  • Building Regulations Approved Document E (E&W), Technical Handbook Section 5 (Scotland) and Technical Handbook G (Northern Ireland) compliant.
  • Suitable on timber and concrete floors.
  • Suitable for refurbishment and new build developments.
  • Good footfall noise reduction and thermal conductivity.
  • Minimum construction - low floor build-up.
