A method is provided for producing a heated laminated windshield construction. Initially, a transparent material to be provided as the outer layer of such a laminated windshield is selected. A transparent basecoat is applied on the inner major surface of the outer layer. A quantity of electroconductive metal is deposited onto the basecoated surface to form a metal strike coat. A portion of the metal strike coat is masked so that unmasked portions of the strike coat comprise the pattern of the electroconductive metal film runs to be formed on the inner major surface. An electroconductive metal is electroplated onto the unmasked portions of the strike coat. Portions of the strike coat onto which no metal was electroplated are removed to thereby leave on the inner major surface of the layer a plurality of spaced apart electroconductive metal film runs comprising electroplated metal and the portion of the metal strike coat beneath the electroplated metal. A major surface of a transparent material is then bonded to the inner surface of the outer layer to thereby sandwich the spaced apart electroconductive metal film runs between the layers.

A method for producing clear, cured transparent polycarbonate laminates comprises directly bonding a sheet of transparent thermosetting polyurethane sheet to a polycarbonate sheet to produce a laminate, heating the laminate above the softening point of the polycarbonate sheet, and forming the laminate to a desired curvature.
