The electric underfloor heating system with innovation at it's heart
TILE | STONE | MESH
Inspired since it’s inception, ThermoSphere Mesh has been at the forefront of product innovation, it was in fact the first electric underfloor heating mesh system to feature a fully self-adhesive element.
It was also the first mesh system to introduce a 200W per metre square output capability. Not only that, but it was first in it’s class again to feature a twisted double core heating cable, designed to reduce stress on the cable – to which it remains the only one in the market, today.
ThermoSphere Mesh really is British innovation at it’s finest, and electric underfloor heating too.

Underfloor heating installation made easy
ThermoSphere Mesh is fully self-adhesive which speeds up installation making it easier for self-levelling and tile fixing.
Simply roll out the Mesh in a run to fit the space you are heating and then cut and turn (the mesh, not the wire) to turn a corner and start a new run.
Compatible with every floor finish
ThermoSphere Mesh can be installed in any living space (even in wet rooms!) and under almost any floor finish when installed with the appropriate accessories.
Protection and reliability throughout
The unique, twin twisted stress free cable construction creates a longer lasting cable with zero electromagnetic field.
Not only this but the Mesh is installed wire-side-down (again, unique) which means the heating cable is protected from potential damage during installation by the hard wearing mesh layer.
Enhance & maximise your living space
The beauty of electric underfloor heating is that it allows you to claim back your precious wall space which your radiators have previously stolen.
At only 3.5mm thick, all you'll ever notice from it is the superior levels of warmth and comfort you now have, that you perhaps didn't have before.
