Which Insulation Board Do I Need for Electric Underfloor Heating?

Choosing the right insulation board is essential for an efficient electric underfloor heating system. The correct board prevents downward heat loss, improves responsiveness, and ensures a stable floor surface.

ThermRite™ Insulation Board

A cost-effective, professional-grade option available in 3 mm, 6 mm and 10 mm thicknesses. Suitable beneath most electric heating systems to reduce heat loss and improve efficiency.

EcoMax Lite Boards

6 mm insulation panels designed specifically for use with our Ecofilm and Ecofoil systems. These boards form the ideal base layer for floating installations.

Tile Backer Boards

Our strongest insulation boards, developed for undertile heating systems. Manufactured with a cement-coated polystyrene core, they add exceptional compressive strength, withstand high loads immediately after laying, and improve heating response times. Perfect under tiles and stone floors where strength and stability are key.

EcoMax-Duo Boards

A dual board overlay system designed for use with Ecofilm electric heating. Supplied in packs of base and top boards with adhesive layers, EcoMax-Duo provides a smooth, stable subfloor ready for soft floor coverings such as carpet, lino and luxury vinyl.

Why use insulation boards?

Adding insulation boards beneath your electric underfloor heating ensures heat is directed upwards into the room instead of being lost into the subfloor. This reduces running costs, speeds up heat-up times and extends the lifespan of your flooring.
