ABSTRACT:
A coated article of manufacture comprises a substantially transparent substrate with a substantially transparent dual-function coating on a surface of the substrate. The coating provides low emissivity and high anti-solar performance properties. It comprises a first anti-reflection layer of dielectric material, preferably tungsten oxide. An infra-red reflective layer of silver metal overlies the anti-reflection dielectric layer. Optionally, a buffer layer is positioned between the anti-reflection layer and the infra-red reflective layer. Also, optionally, a color control layer may be positioned between the anti-reflection layer and the substrate. A silicon buffer layer, directly overlies the infra-red reflective layer of silver metal. A second anti-reflection layer of tungsten oxide overlies the buffer layer. In accordance with a method of manufacturing the coated article, each of the layers of the dual-function coating are deposited in turn by cathodic sputtering in a multi-station sputtering chamber. Passing the transparent substrate through the sputtering chamber a second time to produce a double-layer coating structure is found to provide especially high quality performance characteristics.
