Opposed functional coatings having comparable single surface reflectances
First Claim
1. A sheet-like pane having generally opposed first and second major surfaces, the first major surface bearing a low-maintenance coating, the second major surface bearing a low-emissivity coating, wherein one of the low-maintenance coating and the low-emissivity coating has a single surface reflectance that is less than 3 times, and more than one-third, that of the other coating, wherein the low-emissivity coating includes an infrared-reflecting film comprising silver, and the low-maintenance coating includes a silicon-containing base film having a thickness of less than 100 angstroms and a titanium-containing film having a thickness of less than 50 angstroms.

21. A method of depositing a low-emissivity coating onto a first major surface of a sheet-like pane and depositing a low-maintenance coating onto a second major surface of the pane, the method comprising:
-
depositing a low-maintenance coating onto the first major surface, wherein depositing the low-maintenance coating comprises depositing a silicon-containing base film to a thickness of less than about 100 angstroms directly on the first major surface, and depositing a titanium-containing film to a thickness of less than about 50 angstroms directly on the base film; and depositing a low-emissivity coating onto the second major surface, wherein one of the low-emissivity coating and the low-maintenance coating has a single surface reflectance of less than 3 times, and more than one-third, that of the other coating. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29)
