Patent ID: 7314668

Claim:
A coated article that is a vehicle windshield, comprising: a coating provided on a glass substrate, said coating comprising from the glass substrate outwardly: a) at least one dielectric layer; b) a first contact layer, and another layer provided between at least layers (a) and (b); c) a first IR reflecting layer comprising Ag; d) a second contact layer, said first IR reflecting layer contacting each of said first and second contact layers; e) at least one dielectric layer; f) a third contact layer; g) a second IR reflecting layer comprising Ag; h) a fourth contact layer, said second IR reflecting layer contacting each of said third and fourth contact layers; i) at least one dielectric layer, and another layer provided between at least layers (h) and (i); wherein after being heat treated (HT) and laminated in the form of a vehicle windshield said coated article has a visible transmittance of at least 70%, a T solar no greater than 50%, an R solar of at least 26%, a sheet resistance (R s ) of no greater than 8.0 ohms/sq, a glass side reflective color coordinate value a* G (normal viewing angle) in the range of from −2.0 to +2.0; and wherein said glass side reflective color coordinate value a* G does not change by more than 3.0 upon a 60° change in viewing angle (VA) from normal; and wherein said dielectric layer a) and/or said dielectric layer i) includes both Si and Zr and does not directly contact any contact layer, and wherein the metal portion of the dielectric layer a) and/or i), said metal portion not including Si because Si is a non-metal, consists of Zr.
