ABSTRACT:
The present invention provides is a method of making an infrared reflective coated article, including the steps of: providing a substrate; depositing a first dielectric layer over at least a portion of the substrate, the layer comprising a first zinc stannate film deposited over the substrate, and an electrical enhancing film deposited over the first zinc stannate film, the electrical enhancing film selected from zinc oxide-tin oxide film and a second zinc stannate film; forming an infrared reflective layer on the first dielectric layer; forming a metal primer layer over the infrared reflective layer; forming a second dielectric layer over the primer layer; and forming a protective layer of at least two films in a position where it can provide durability to the dielectric layer, infrared reflective layer, metal primer layer, and second dielectric layer.
