The Devimat heating mats, available from Devex Systems, consist of a thin heating cable pre-laid on a self adhesive fibreglass mesh.

The Devimat heating mats can be covered with a flexible tile adhesive making them ideal for new construction or renovations where minimising floor height loss is important.

Alternatively, a self levelling compound may be used, for instance when used in an under carpet application.

In this case, the levelling bed needs to be at least 12mm thick and deep enough to cover the mat, sensor cable and cold tail joint.

The Devimat cable heats up the surrounding glue bed or levelling bed, which in turn heats up the floor covering above and radiates heat into the room.
