The underfloor heating is applied in a thick layer of screed, resistant to all the humidity and chemicals that could arise during construction. The cable, which has a thickness of about 1 cm, is placed on a flat and insulated floor, so as to avoid heat loss, and is directly covered by a layer of wet concrete or self-levelling screed, measuring between 2 to 3 cm.
This layer of screed simultaneously serves to protect the heating cable as well as the heat-accumulating layer.
This kind of underfloor heating should preferably be installed during the construction phase or whenever a height of at least 4 cm is available, to be able to incorporate the insulation, heating cable and the layer of screed.
A choice of three kinds of resistors is available. All the resistors are certified according to VDE and OVE norms.
This underfloor heating system is to be applied in a layer of screed and comprises a resistor (heating cable) and impermeable junction wires, which are connected via a refractory hose (impervious to heat), in two different lengths, 3 m and 3m + length of the heating pad, for all sizes of rooms.
