Articles including anticondensation and/or low-E coatings and/or methods of making the same
View Patent ↗Certain example embodiments of this invention relate to articles including anticondensation and/or low-E coatings that are exposed to an external environment, and/or methods of making the same. In certain example embodiments, the anticondensation and/or low-E coatings may be survivable in an outside environment. The coatings also may have a sufficiently low sheet resistance and hemispherical emissivity such that the glass surface is more likely to retain heat from the interior area, thereby reducing (and sometimes completely eliminating) the presence condensation thereon. The articles of certain example embodiments may be, for example, skylights, vehicle windows or windshields, IG units, VIG units, refrigerator/freezer doors, and/or the like.
1. A coated article, for use in a window, comprising:
a coating supported by a glass substrate, wherein:
the coating comprises the following thin-film layers moving away from the glass substrate:
a first layer comprising silicon nitride located on and directly contacting the glass substrate;
a layer comprising an oxide of titanium located on the glass substrate over at least the first layer comprising silicon nitride, wherein the first layer comprising silicon nitride is substantially thicker than is the layer comprising the oxide of titanium;
a second layer comprising silicon nitride located over and directly contacting the layer comprising the oxide of titanium;
a transparent conductive layer comprising indium tin oxide (ITO) located over and directly contacting the second layer comprising silicon nitride,
a third layer comprising silicon nitride located over and directly contacting the transparent conductive layer comprising indium tin oxide (ITO), and
a protective layer comprising zirconium oxide located over and directly contacting the third layer comprising silicon nitride, and wherein the coating does not contain any silver-based layer.
2. An IG window unit including the coated article of claim 1 .
