Glazing including a network of conductive wires

Abstract

The invention relates to glazing provided with conductive wires. The glazing of the invention includes enamelled conductive wires applied by screen printing. When submitted to a zebra test (DIN 52305), with the conductive wires oriented parallel to that of the test image, and when the glazing receives a light beam incident at an angle of 30 DEG relative to the normal of the glazing, the increase in the distortion relative to that of a glazing without conductive wires does not exceed 70% and preferably does not exceed 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...
