The improvement and further training achieved according to the invention Such a hot cladding is characterized by one inside the synthetic resin, parallel to the hot element and electrically isolated from this arranged metal insert »which is electrically grounded *

The susfsliche XinfOgen a grounded metal insert can the electrical hot element with a current of high or medium Voltage can be supplied without that · any danger touching the hot cladding «'This advantage is of particular importance in the healing of living spaces, since the heat know cladding to be connected directly to the electricity network; When using the invented HcIs * cladding on road surfaces can have a · supply voltage of several hundred volts are applied »which reduces the length of the Heating elements increased considerably and better electricity utilization can be obtained than is possible with a low voltage current supply.

The invention also relates to a method for producing a such heating cladding, initially at least one layer

The attached drawing shows an example of an embodiment of a heating cladding according to the invention in one part. section shown.

Here, the heating cladding consists of a first synthetic resin layer 1, which rests against a base 2 to be provided with the heating cladding «between the first synthetic resin layer 1 and a second one Synthetic resin layer 3, the electrical heating element 4 is embedded

The invention is now parallel to the heating element 4 and electrical insulated therefrom between the synthetic resin layer 3 and a third Synthetic resin β layer 5, which can be the outer cover layer that Metal insert 6 arranged «This metal insert 6 is preferably made of an openwork, lattice-shaped metal plate, a

For the practical implementation of the invention can be proceeded approximately as follows in a preferred manner;

to
A layer of a mouldable or liquid synthetic resin curable in air with polymerisation is first applied to the base provided with a heating cladding / The polyamide available on the market consists of polyamide and cures with polyaddition thermal and electrical insulation works. The heating element is then coated with a second layer of air-hardenable resin, whereupon a thin aluminum sheet is applied to this second synthetic resin layer, which is provided with a large number of openings and has the shape of a grid. The aluminum sheet is then covered with a third synthetic resin layer, which

The aluminum plate also has a wipe between the widths and third synthetic urine layer - «" "protruding aneat * on» with which • i «to« int suitable srdleituag electrically conductive connected will.
