  • Minimum 240 mm engineered 'I' joist.
  • Minimum 18 mm oriented strand board (OSB).
  • Approved acoustic resilient insulation.
  • Polythene separating layer (500 gauge minimum).
  • Optional underfloor heating elements.
  • Supaflo TimBRE screed.

The product can be used with either warm water or electric underfloor heating systems in both commercial and residential developments. Its use will help to improve the acoustic performance of the floor to meet or exceed the requirements set out in Building Regulations Approved Document E.
