The full package
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.
Impact sound reduction
One of the most common paths of noise is hard floors such as timber, particularly frustrating for your client if they live in a block of flats and hear their neighbours footseps every 5 minutes. Solve this problem for them by using foil, with its 19dB impact sound insulation.
Putting installers first
ThermoSphere Foil is the only one of its type to include a continuous earth braid and the first fully earthed foil in the UK to feature accessible cable loops making installation a breeze. The double layer of foil is specifically designed to protect the heating element and achieve an even spread of heat to the floor above. Accessible cable loops simplify cut and return installation and provide abrasion protection for the heat element.
Heating carpeted or timber floors
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 install a layer of HDF overlay boards to provide a flat surface to walk on. 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.
