Abstract
This disclosure is directed to a heat reflective glazing including a glass sheet having two generally planar parallel surfaces or sides with a multilayer coating on one of the side, and a method of producing such glazing. The side of the glass sheet having the multilayer coating thereon is designated as the film or coated side while the other side is designated as the glass side of the glass sheet. The multilayer coating comprises a first silicon-containing coating formed directly on the glass surface, a titanium nitride-containing coating overlying the first coating, a second silicon-containing coating covering the titanium nitride-containing coating, and an optional abrasion resistant coating, e.g., comprising tin oxide, on the second silicon-containing coating. The process for producing the coatings is a chemical vapor deposition process preferably carried out during the production of glass by the float process.
