Abstract
A method of making a glazing unit comprises sputter coating surface of a substrate ply with a first film of dielectric material and then a substantially transparent, electrically conductive coating, and then laminating the coated surface of the substrate ply to a laminating ply of polymeric material. The first film of dielectric material is sputtered onto the surface of the substrate followed by sputtering, in a non-oxidizing atmosphere, an electrically conductive film of silver metal over the first dielectric film. An adhesion film of copper or zinc is sputtered over the silver metal film in a non-oxidizing atmosphere. A film of tantalum pentoxide is then sputtered over the adhesion film. Applications include, for example, glazing units for solar load reduction and electrically heated glazing units.
