ThermoSphere Electric Underfloor Heating Foil

Incredible versatility

ThermoSphere Foil is a super-thin underfloor heating foil that brings the luxuriousness of underfloor heating to laminate flooring. Less than 1mm thick, ThermoSphere Foil is designed to give the perfect spread of heat when installed beneath floating laminate flooring and engineered boards, and other applications where height build up is crucial.

ThermoSphere Foil under-laminate heating mats are available in a range of sizes and can be 'cut and returned' just like a ThermoSphere Mesh mat. This gives you greater flexibility when ordering the heating as you don't need to calculate individual runs of foil heating. We can also provide bespoke standard foil room sets to fit your specifications.
