Superior heat exchange
The double layer of foil is specifically designed to protect the heating element and achieve an even spread of heat to the floor finish.
Award-winning ThermoSphere Foil is the most advanced electric underfloor heating system for wood, carpet and vinyl floor finishes. It's the only foil heating system that is fully compliant with Section 753 of the 18th Edition Wiring Regulations making it the safest of its type, and for peace of mind, it's backed by a lifetime warranty.
If you like convenience, you can buy a complete kit from your local ThermoSphere retailer. The kit includes everything you need; 140W/m2 ThermoSphere Foil, underlay and our unique cushioning and acoustic overlay. This combination only adds 9mm to the floor build up.
Foil electric underfloor systems are ideal for floating floor finishes such as wood. The heating cable is wrapped by two layers of foil which provides great thermal conductivity and fast heat up times. Unlike similar systems, ThermoSphere Foil has an abundance of features which make it the safest and easiest system to install.
One of the most common paths of noise is hard floors such as timber. This is particularly significant in blocks of flats where hearing your neighbour’s footsteps is not uncommon. The combination of the 2mm cushioning overlay and 5mm cushioning underlay provides 19dB impact sound insulation.
Traditional solid timber flooring or engineered wood flooring work well with a foil electric underfloor heating system. Board thickness is a key consideration and we would recommend a maximum thickness of 18mm and a floor surface temperature of 27oC to not be exceeded.
Yes. You can even use a foil electric underfloor heating system under carpeted floors! As well as ensuring your carpet doesn't exceed a tog rating of 2.5, it's equally important to not over insulate the layers above your floor heating system.
