Recommended for 14mm engineered wood flooring.

The Profoil® XTRA Panel is a lightweight high compressive extruded polystyrene panel with a 100 micron foil face foiled into the grooved, Maximising contact between the aluminium foil (the heat diffusion device) and the underfloor heating pipes is an important parameter in optimising the thermal output of a warm-water underfloor heating system.


Light weight, easy to install dry-fit solution, with high heat output.

ICONS – Light weight, fast heat up, high heat output, (14mm engineered wood?)


The perfect solution for those looking to lay engineered wood flooring on upper floors.


  • Panel Dimensions: 1200 x 600 x 20mm (0.72m² = 1 panel)
  • Material: Expanded polystyrene (300KPA)
  • Pipe Diameter: 16mm
  • Foil Thickness: 100 microns
  • Thermal Conductivity: 0.034 W/mk
  • Pipe Runs: 4 grooves @ 150mm centres with radius/bulb returns + 3 cross runs at the top to return to manifolds.

Expanded and extruded options available on request call 01923 725180 to discuss.


All our systems are energy efficient, but to assist you with your selection we have graded them A to C, where A is the most energy efficient. Note floor coverings used impact heat output.

Energy efficient rating: B+
