The most advanced heating foil

ThermoSphere Foil electric underfloor heating is a hard-wearing foil designed for a long-lasting installation with efficient heat transfer. The double layer of foil is specifically designed to protect the heating element and achieve an even spread of heat to the floor above.

As safe as it is efficient and robust

Electrical safety is paramount.
It’s for that reason we have ensured ThermoSphere Foil has continuous earth braid protection running throughout the entire length of the heating cable. So you can easily install it with complete peace of mind.

Innovative design for an easier installation

Equipped with a cushioning underlay, the heating cable inside ThermoSphere Foil is embedded to remain totally protected from abrasion. Accessible cable loops simplify cut and return installation and provide protection for the heating element after installation is complete.
