Superior heating cable

Unique TwistedTwin heating cable technology reduces cable stress which helps to create a safer, longer lasting heating cable making it the most robust heating cable available.

The heating cable is pressed in-between dimples (or studs)  of the membrane which protects the cable from any damage caused by a heavy hand using a trowel.

Choose your heating output

ThermoSphere Membrane allows for different heating outputs. You do this by changing the spacing between the cable. Use a two-stud spacing for an output of 195W/m2 (ideal for wet rooms) and a three-stud spacing for an output of 130W/m2 (great for well-insulated buildings).
