Integrated insulation and underfloor heating system for timber batten floors.

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

Our FoilBatten system can be laid between timber battens at 400 centres. This system is most appropriate within a timber batten floor where others are to install their own structural floor over the battens.

The universal FoilBatten 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 panels are designed so that when a floor deck is laid over and fixed to the battens of the same depth they will be in direct contact with the heat diffuser, ensuring good thermal transfer.

The nature of the FoilBatten panel to transfer heat efficiently increases performance by over 30% compared to systems that rely on air and do not use heat diffusers. Once the panels are in place the pipe is pressed into the channels piercing the foil diffuser and fitted into the notches where the pipe passes between battens.


OMNIE FoilBatten system using 12mm PE-RT to DIN 4726 pipe installed into FoilBatten panels comprising of XPS expanded polystyrene insulation with pre-bonded heat diffusers to be installed between battens at 400mm centres. Floor deck to be laid and fixed over. The system to be designed, installed and commissioned to BS1264.
