Our FoilBoard range is a super high efficiency, easy to install heating panel, which is independently tested at BSRIA for outstanding heating performance.

For suspended Floor Types
Fully foiled heat diffuser layer to maximise heat output and warm up time
No noise on warm up or cool down
Easy to trim on site due to high density panel construction

Combined insulation and underfloor heating system for timber floors.

Why FoilBoard?

  • 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

Underfloor Heating System with Combined Insulation and Heat Diffuser

Our FoilBoard system provides assured performance in timber suspended floors. The FoilBoard panels are manufactured from XPS insulation with 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 supported by battens or L shaped brackets. 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.

Our FoilBoard suspended system provides assured performance in timber suspended floors.

Our FoilBoard panels are manufactured from high quality extruded polystyrene (XPS) insulation and faced with a highly conductive aluminium emitter. The panels are laid between joists supported by battens or brackets. This ensures that the system is in direct contact with the underside of the floor deck, maximising the transfer of heat from pipe to the floor deck.

OMNIE FoilBoard Suspended system is a multi directional panels comprising of 50mm or 75mm XPS insulation with pre-bonded heat diffusers and to be installed between joists at 400mm & 600mm centres. 12mm PE-RT pipe to be inserted into the pre-routed grooves. Floor deck to be laid and fixed over. The system to be designed, installed and commissioned to BS1264.
