Abstract

A glass sheet includes a coating comprising at least one silver layer and inner and outer antireflection layers. The glass sheet is formed by a magnetron sputtering process. The inner antireflection layer is a multiple layer comprising a layer of a titanium oxide applied by medium frequency magnetron sputtering and a layer of a metal oxide between the titanium oxide layer and a silver layer.
