Abstract
Abstract A glazing unit comprises a substrate ply and a laminating ply laminated to a surface of the substrate ply. A coating on a laminated surface of the substrate ply is a film stack comprising a film of electrically conductive material covered by a film of dielectric material. The film of dielectric material immediately adjacent the laminating ply comprises a layer of silicon dioxide immediately adjacent the laminating ply and a layer of dielectric material of refractive index greater than 1.5 between the silicon dioxide and the conductive material. Applications include, for example, glazing units for solar load reduction and electrically heated glazing units.
