A plastic window panel (1') with embedded electrical conductor wires (4) for heating or an antenna has the wires applied to the surface of a first plastic layer (2) between 0.1 and 1 mm thick, which is then covered by a second layer (3) of plastic by injection molding. The wires, which are between 5 and 500 microns thick and of tungsten or other material, can be imprinted in the first plastic layer by the action of heat. They are applied or stretched over the layer in the injection mould, and the main mass of plastic forming the body of the window is injected over it, obviating the need for adhesive and producing a more or less homogeneous panel. A second layer (2') of plastic with wires can be applied on top of the injected mass. |
