The ThermoSphere Foil system is the perfect balance for floating floors.
ThermoSphere Foil Underfloor Heating is a foil electric underfloor heating system, designed to provide the perfect level of warmth without overheating, warping, or distorting soft floor finishes. This makes it the ideal underfloor heating system for wood, carpet and vinyl floor finishes. In 2015 it became the first fully earthed foil electric underfloor heating system in the UK to feature easily accessible cable loops designed to assist with an easier installation.
Available as a handy kit, ThermoSphere Foil comes the 140W/m² foil, it's unique cusioning underlay and acoustic dampening overlay in one convinient cost-saving box. ThermoSphere Foil Underfloor Heating is compatible for use with all ThermoSphere Thermostats.
- Efficient heat exchange foil:
The double layer of foil is specifically designed to protect the heating element and achieve an even spread of heat to the floor finish above. - Easy cut and return installation:
The accessible cable loops simplify cut and return installation and provide abrasion protection for the heat element after installation is complete. - Continuous earth protection braid:
ThermoSphere Foil Underfloor Heating has a continuous earth braid protection running throughout the entire length of the heating cable. So you can easily install it with complete peace of mind. - Low profile cold tail:
An extra malleable, low profile cold tail makes installing foil easy. The cold tail is only 4mm thick and can be concealed within the insulation.
