Abstract:
1. A heat treatable coated article, comprising a multilayer thin film coating supported by a glass substrate, the coating comprising, in order moving away from the substrate: a first silicon-based layer; a first dielectric layer; a second dielectric layer split by a third dielectric layer so as to form first and second portions of the second dielectric layer; a metallic or substantially metallic infrared (IR) reflecting layer comprising silver over and directly contacting the second portion of the second dielectric layer, wherein the coating contains only one IR reflecting layer comprising silver so that each of the first silicon-based layer, the first dielectric layer, the second dielectric layer and the third dielectric layer are all located between the glass substrate and the IR reflecting layer; an upper contact layer comprising an oxide of Ni and/or Cr directly over and contacting the IR reflecting layer; a fourth dielectric layer; and a second silicon-based layer, wherein the third dielectric layer comprises either titanium oxide or tin oxide.
