| 摘要 |
The invention provides a glazing sheet and a low-emissivity coating on the glazing sheet. The low-emissivity coating comprises, in sequence moving outwardly from the glazing sheet, a layer comprising oxide film, nitride film, or oxynitride film, an infrared-reflective layer, a nickel-aluminum blocker layer, and an oxide layer. Also provided are methods of depositing such a low-emissivity coating. |

1. A multiple-pane insulating glazing unit having a between-pane space, the multiple-pane insulating glazing unit comprising a pane having a surface coated with a low-emissivity coating, said surface of said pane being exposed to said between-pane space, the low-emissivity coating comprising, in sequence moving outwardly from said surface of said pane, 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 dielectric middle 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, and a dielectric top coat comprising an oxide film in contact with the second nickel-aluminum blocker layer, the first and second infrared-reflective layers each comprising silver, wherein the low-emissivity coating has only two silver-containing infrared-reflective layers and the multiple-pane insulating glazing unit has a visible transmittance of between 0.3 and 0.5. |
