It's installed wire-side-down which means the heating cable is protected by the mesh from damage during installation.

Use for walls, not just floors

ThermoSphere Mesh is so versatile, you can even add that little bit of extra comfort by installing it under wall tiles in wet rooms and shower cubicles.


Floor finishes

ThermoSphere Mesh is recommended for tile and stone floors, but with the right accessories it can be used in almost any type of floor specification including carpet and vinyl, as well as wet rooms.

A choice of output

The higher the wattage, the faster the heat-up time. For example 200W/m2 is perfect for high demand rooms like conservatories. 150W/m2 is a great primary heat source for well insulated rooms and 100W/m2 is usually for floor warming only.
