Abstract
Coated articles include at least one functional infrared (IR) reflecting layer(s) sandwiched between at least dielectric layers. The dielectric layers may be of or including silicon nitride or the like. At least one of the IR reflecting layers is of or including titanium nitride (e.g., TiN).
Claims38
A coated article including a coating supported by a glass substrate, the coating comprising:
- a first dielectric layer comprising silicon nitride;
- a first infrared (IR) reflecting layer comprising a nitride of titanium on the glass substrate over at least the first dielectric layer comprising silicon nitride;
- a second dielectric layer comprising silicon nitride on the glass substrate over at least the first dielectric layer comprising silicon nitride and the first IR reflecting layer comprising the nitride of titanium;
- a second layer IR reflecting layer comprising a nitride of titanium on the glass substrate over at least the second dielectric layer comprising silicon nitride;
- wherein the second dielectric layer comprising silicon nitride is located between and directly contacting the first and second IR reflecting layers comprising nitride of titanium;
- a third dielectric layer comprising silicon nitride on the glass substrate over at least the second IR reflecting layer comprising the nitride of titanium;
- wherein the coating contains no IR reflecting layer based on silver, and contains only two IR reflecting layers;
- and
- wherein the coated article measured monolithically has:
- a visible transmission from about 12-70%, a glass side visible reflectance no greater than 14%, and a glass side reflective a* value of from −10 to +1.6.
