ABSTRACT A method for forming a vehicle window assembly includes applying a band of an opaque ceramic enamel material to a predetermined peripheral portion of a sheet of relatively flat glass, and heating the glass to a prefire temperature to fuse the opaque material to the glass. An electrically conductive material is applied to the band in a predetermined pattern to form a pair of bus bars typically along the top and bottom edges of the sheet of glass. The glass is again heated to fire the bus bar material and soften the glass for bending into a desired window shape. A mask is applied to the bus bars for later connection of electrical leads and the sheet of glass is washed prior to the next operation. An electrically conductive film is applied to the second surface of the sheet of glass and electrically connected to the bus bars. The sheet of glass is laminated to a sheet of plastic material which covers the electrically conductive film and, typically, the plastic sheet is laminated to a second sheet of glass which has been preformed, ie., bent, to conform to the first sheet. Electrical leads are attached to the bus bars to complete the window assembly. The electrically conducting film and glass sheet composition and thickness are chosen to maximize for the window assembly the desired performance characteristics of resistance, transmission, reflection and color - all of which are mutually interactive.
