Low solar heat gain coatings, laminated glass assemblies, and methods of producing same

A laminated glass panel including two glass panes and an interlayer, the interlayer sandwiched between the two glass panes and bonded thereto, at least one of the two glass panes having an interior surface that bears a coating, the coating comprising, in sequence moving away from said interior surface and toward the interlayer, a first indium tin oxide film, a first nickel aluminum film, a second indium tin oxide film, a second nickel aluminum film, and an overcoat layer, the first indium tin oxide film having a thickness of between 480 Å and 725 Å, the first nickel aluminum film having a thickness of between 80 Å and 120 Å, the second indium tin oxide film having a thickness of between 580 Å and 870 Å, and the second nickel aluminum film having a thickness of between 65 Å and 100 Å, wherein the first nickel aluminum film is in contact with both the first and second indium tin oxide films.

A laminated glass panel including first and second glass panes and an interlayer, at least one of the two glass panes having an interior surface that bears an ITO-based coating, wherein the ITO-based coating comprises, in sequence moving away from said interior surface and toward the interlayer, a first indium tin oxide film, a first nickel compound film, a second indium tin oxide film, a second nickel compound film, and an overcoat layer, the first indium tin oxide film having a thickness of between 480 Å and 725 Å, the first nickel compound film having a thickness of between 80 Å and 120 Å, the second indium tin oxide film having a thickness of between 580 Å and 870 Å, and the second nickel compound film having a thickness of between 65 Å and 100 Å, wherein the first nickel compound film is in contact with both the first and second indium tin oxide films, the interlayer being sandwiched between the first and second glass panes, the laminated glass panel having an exterior reflected color characterized by a chroma magnitude number of less than 1.

A laminated glass panel including first and second glass panes and an interlayer, the interlayer being sandwiched between the first and second glass panes, the first glass pane having an interior surface facing the interlayer, the second glass pane having an interior surface facing the interlayer, the interior surface of the first glass pane bearing an ITO-based coating, wherein the ITO-based coating comprises, in sequence moving away from the interior surface of the first glass pane and toward the interlayer, a first indium tin oxide film, a first nickel-aluminum film, a second indium tin oxide film, a second nickel-aluminum film, and an overcoat layer, wherein the first indium tin oxide film has a thickness of between 480 Å and 725 Å, the first nickel-aluminum film has a thickness of between 80 Å and 120 Å, the second indium tin oxide film has a thickness of between 580 Å and 870 Å, and the second nickel-aluminum film has a thickness of between 65 Å and 100 Å, wherein the first nickel-aluminum film is in contact with both the first and second indium tin oxide films, the interior surface of the second glass pane bearing a low-emissivity coating, the low-emissivity coating comprising three silver layers.
