The Thermonet matting is available in a kit which includes all the items (except insulation) that you will require for installation of your underfloor heating. Thermonet features 3.5mm TwistedTwin cable, self-adhesive mesh and our low-profile cold tail connection cable. Thermonet underfloor heating cables have a tough fluoropolymer coating on the outside and internal conductors, a continuous armoured earth sheath and multi-shrand twin conductors. The conductors as twisted together to eliminate electromagnetic field (EMF) and neutralise the stress, expansion and contractions of the cable along the entire length; resulting in a more robust longer lasting cable.
