Glazing including network of conductive wires

Abstract

The invention relates to glazing units provided with conducting wires. The glazing units according to the invention comprise enameled conducting wires applied by screen-printing. When subjected to a “zebra” test (DIN 52305), in which the conducting wires are oriented parallel to those of the image of the test and the glazing receives the incident light beam at an angle of 30° C. in relation to the normal to the glazing, the increase in distortion in relation to that of the glazing without conducting wires is at most 70% and preferably at most 50%.

Description

technical field [0001] The invention relates to glass doors and windows comprising a wire mesh especially for automobiles. Background technique [0002] The wires of vehicle glass doors and windows, especially the heating wires, are basically of two types. The first type consists of the use of tiny diameter metal wires, especially tungsten wires, which can be inserted into the thermoplastic interlayers of sheet glass windows and doors. The wires used, for example, in heating glass doors and windows, especially windshield molding, have extremely small diameters so as not to alter the visual effect of these glass doors and windows. The second type, which is used almost universally, corresponds to the wires applied in the form of a resistive glaze to a given glass door or window. Most often, these glazed wires are present on the side of the glass door and window facing the driver's cab and are thus vulnerable to mechanical or chemical damage. There is therefore a need for wi...
