      These thermal insulation boards are ideal for use where underfloor heating is to be laid onto an uninsulated subfloor or into a room such as a conservatory with high heat loss. An underfloor heating system laid on to thermal insulation boards will react faster and will run more efficiently than a system laid directly onto a concrete base.

      When choosing the thickness of boards most suitable for your installation you should consider a number of factors. Firstly, the build height that you have available to you may limit you to, for example, a maximum board thickness of 6mm. Additionally, if you are using the boards to secure a wooden base you should always use 10mm thick boards.

      If, however, you have the available build height we would recommend using our 20mm insulation boards as these provide a very good trade off between cost and insulation efficiency providing a UValue(W/m²k) of 1.35. Our 10mm boards have a U Value of 2.70 and our 6mm boards a value of 4.50.
