The invention provides a glazing sheet and a coating on the glazing sheet. The coating comprises, in sequence moving outwardly from the glazing sheet, a dielectric base coat comprising oxide film, nitride film, or oxynitride film, a first infrared-reflective layer, a first nickel-aluminum blocker layer in contact with the first infrared-reflective layer, a first dielectric spacer coat comprising an oxide film in contact with the first nickel-aluminum blocker layer, a second infrared-reflective layer, a second nickel-aluminum blocker layer in contact with the second infrared-reflective layer, a second dielectric spacer coat comprising an oxide film in contact with the second nickel-aluminum blocker layer, a third infrared-reflective layer, a third nickel-aluminum blocker layer in contact with the third infrared-reflective layer, and a dielectric top coat comprising an oxide film in contact with the third nickel-aluminum blocker layer. Also provided are methods of depositing such a coating.
A multiple-cavity controlled transmission coating on a substrate, the substrate being a sheet of glass, the multiple-cavity controlled transmission coating comprising three infrared-reflective layers and a nickel-aluminum blocker film such that the multiple-cavity controlled transmission coating includes at least one contiguous sequence of, moving outwardly away from the substrate, a zinc tin oxide film, a silver or silver-containing film, and the nickel-aluminum blocker film, wherein the multiple-cavity controlled transmission coating has only one nickel-aluminum blocker film.
A multiple-pane insulating glazing unit having a substrate coated with a multiple-cavity controlled transmission coating, the substrate being a sheet of glass, the multiple-cavity controlled transmission coating comprising three infrared-reflective layers and a nickel-aluminum blocker film such that the multiple-cavity controlled transmission coating includes at least one contiguous sequence of, moving outwardly away from the substrate, a zinc tin oxide film, a silver or silver-containing film, and the nickel-aluminum blocker film, wherein the multiple-cavity controlled transmission coating has only one nickel-aluminum blocker film, the multiple-cavity controlled transmission coating having a sheet resistance of less than 3.0 ohms per square and an emissivity of less than 0.03, the multiple-pane insulating glazing unit having a solar heat gain coefficient of less than 0.23.
