Abstract

This application relates to a coated article including at least one infrared (IR) reflecting layer of a material such as silver or the like in a low-E coating. In certain embodiments, at least one layer of the coating is of or includes zirconium oxide (e.g., ZrO2) or zirconium silicon oxynitride (e.g., ZrSiOxNy). When a layer comprising zirconium oxide or zirconium silicon oxynitride is provided as the uppermost or overcoat layer of the coated article (e.g., over a silicon nitride based layer), this results in improved chemical and heat stability in certain example embodiments. Coated articles herein may be used in the context of insulating glass (IG) window units, vehicle windows, or in other suitable applications such as monolithic window applications, laminated windows, and/or the like.
