Coated article having a low emissivity (Low-E) coating with an infrared (IR) reflective system having a silver and zinc based barrier layer

摘要

The coated article is adjacent to at least one barrier layer comprising metallic or substantially metallic zinc (Zn) to improve the chemical durability properties of the Low-E coating. And a silver (Ag) based infrared (IR) reflective layer on a glass substrate provided in contact therewith. In certain exemplary embodiments, the silver-based layer is between a metallic or substantially metallic first barrier layer and a second barrier layer that both consist of or include zinc (Zn). May be sandwiched. The IR reflective layer and the zinc-based barrier layer are part of the low emissivity (Low-E) coating.
