Underfloor heating

Floating floor constructions

A floating floor is a floor that doesn't need to be nailed or glued to the subfloor and is supported on a continuous layer, usually of insulation.

Nu-Heat’s floating floor constructions comprise Extra High Density (EHD) panels and heat diffuser panels. It is important to fit the UFH over insulation with sufficient strength (kPa) to withstand the load of the intended floor and covering.

How it works

Nu-Heat’s pre-tracked TriPanel is laid over the insulation layer and metal heat diffuser plates are then positioned into the grooves. The heat from the tube is spread quickly and evenly by the diffuser plates, providing excellent heat output.

A floating chipboard or Knauf Brio board deck may be used on top, or the panels can be installed between the joists in upper floors.

Specification considerations
  • Dry floor construction
  • Medium heat output
  • Medium response
  • Lightweight

Installation considerations
  • Quick to install
  • Sits on top of the structural deck
  • Floor components fitted at first-fix stage
  • Requires minimum 18mm chipboard on top
  • Floor coverings can be fitted immediately
