Patent ID: 8734920

Claim:
An insulating glass (IG) window unit including a coated article including a coating supported by a glass substrate, the coating comprising: first and second infrared (IR) reflecting layers comprising silver, wherein said IR reflecting layers are spaced apart from one another by at least one dielectric layer that is located therebetween, and wherein the first IR reflecting layer is located closer to the glass substrate than is the second IR reflecting layer, wherein the first IR reflecting layer has a thickness of from about 125 to 150 Å, and the second IR reflecting layer has a thickness of from about 140 to 200 Å, and wherein the thickness of the second IR reflecting layer is greater than that of the first IR reflecting layer; a bottom dielectric stack provided between the first IR reflecting layer and the glass substrate, wherein the bottom dielectric stack comprises moving away from the glass substrate a first layer consisting essentially of silicon nitride, a layer comprising titanium oxide having a thickness of from about 70-120 Å, and a dielectric layer, and wherein the layer comprising titanium oxide is located between and directly contacting the first layer comprising silicon nitride and the dielectric layer; a center dielectric stack provided between the first and second IR reflecting layers, wherein the center dielectric stack comprises, moving away from the glass substrate, a first layer comprising tin oxide, a layer comprising silicon nitride, a second layer comprising tin oxide, and a layer comprising zinc oxide, wherein the layer comprising zinc oxide is located directly under and contacting the second IR reflecting layer; a contact layer comprising NiCr located over and directly contacting at least one of the IR reflecting layers comprising silver, wherein the contact layer comprising NiCr is from about 4-14 Å thick; and wherein the glass substrate is spaced apart from another glass substrate in the IG window unit, and wherein the IG window unit has an LSG value (T vis /SHGC) of at least 2.0, an SHGC value of no greater than 0.35, a U-value of no greater than 0.30, a visible transmission of at least about 60%, and wherein the IG window unit has at least one of: an outside b* color value of from about −8.5 to −5.5, and a transmissive b* color value of from about 0.75 to 1.85.
