Combined insulation and underfloor heating system for timber floors

  • Fully foiled layer maximises heat output
  • High grade insulation increases energy efficiency
  • Faster to install than traditional insulation panels thanks to multi-direction channels
  • Completely silent on warm up and cool down

Our FoilBoard system provides assured performance in timber suspended floors. The FoilBoard panels are manufactured from XPS insulation, with a 6mm pre-bonded high-density wood layer and a pre-bonded soft temper aluminium. As no thick rigid plates are used the panels can be easily trimmed on site.

The FoilBoard panels are laid between joists and can be supported by OMNIE L brackets or battens. This ensures that the system is in direct contact with the floor deck, maximising the transfer of heat from pipe to the deck. Once the panels are in place the pipe is pressed into the channels piercing the foil diffuser and fitted into notches in the joists as it passes between inter joist spaces.
