Thermonet features 3.5mm TwistedTwin cable, self-adhesive mesh and our low-profile cold tail connection cable. These features make up what we call LayFlat Technology because this combination neutralises tension in the finished product and makes Thermonet easier to fit
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.
Kit items include: Thermonet 150W/m² Mat, Programmable Thermostat (5220A), Floor Temperature Sensor, Sensor Conduit, Fixing Tape, Cable Monitor (6025) & Installation Guide & Warranty Form.
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.
Lifetime Warranty
We are so confident of the quality of our German-made Thermonet Underfloor Heating that we give each system a warranty that lasts a Lifetime with 3 year warranty on our Thermostats.
TwistedTwin cable construction
The unique stress free cable construction creates a longer lasting heating cable with zero electromagnetic field (Zero EMF).
Full self adhesive mesh
The self-adhesive mesh speeds up installation by holding the Thermonet matting to the substrate for easy self-leveling and tile fixing. It also ensures an even and consistent cable spacing across the floor to ensure an even heat.
Heating cable protection
Thermonet is installed wire-side-down which means the heating cable is protected from damage during installation by the hard wearing mesh layer.
Minimal height build-up
Utilising innovative extrusion processes provides real ‘lay flat’ technology that makes installing Thermonet easy. The matting system is only 3.5mm thick with a low profile cold tail of only 4mm thick which is typically concealed within the tile adhesive layer.
