1. A multiple-pane insulating glazing unit comprising two glass panes and a between-pane space, the two glass panes respectively defining two opposed external pane surfaces, a desired one of the two external pane surfaces having a flash-treated transparent conductive oxide coating such that a desired one of the two glass panes is a coated glass pane, said coated glass pane being annealed glass having a surface stress of less than 3,500 psi, the coating comprising a flash-treated indium tin oxide film and an overcoat film on the flash-treated indium tin oxide film, the flash-treated indium tin oxide film having a thickness of less than 1,800 Å, the flash-treated indium tin oxide film being a sputtered film having a surface roughness of less than 3 nm, the flash-treated indium tin oxide film having a sheet resistance of less than 15 Ω/square in combination with said coated pane having a monolithic visible transmittance of greater than 0.82, the flash-treated indium tin oxide film having an optical bandgap of 370 nm or shorter and being characterized by a pre-flash optical bandgap of 400 nm or longer, the multiple-pane insulating glazing unit including an internal pane surface bearing a low-emissivity coating that has only one film comprising silver, the film comprising silver containing at least 50% silver by weight, the low-emissivity coating being exposed to the between-pane space, the multiple-pane insulating glazing unit having a U value of less than 0.25 together with an IGU visible transmission of greater than 75%. |
