Thermal insulation board is ideal for insulating your floor and boosting the warm up time and efficiency of your underfloor heating system. The product is suitable for use beneath any of our underfloor heating systems and the boards can pay for themselves, through reduced heating bills, in as little as 3 years when used on un-insulated bases.

Underfloor heating insulation boards minimise downward heat loss. When 10mm boards are used beneath a 200W system the floor will normally heat up in as little as 20 minutes and they add very little build height for a great energy saving measure.
