A transparent, laminated window having an exposed sheet of plastic material softer than glass adhered to glass, such as a bilayer windshield consisting essentially of an outer glass sheet and an inner preformed sheet of plasticized polyvinyl butyral covered with a thin sheet of polyvinyl fluoride on its exposed surface produced by lamination under heat and pressure with the thin polyvinyl fluoride sheet supported in pressurized engagement against a smooth surface of a mold, which is preferably a second glass sheet having a shape conforming to that of the glass sheet of the resulting laminated window.
