Articles including anticondensation coatings and/or methods of making the same
First Claim
1. A skylight, comprising:
- first and second substantially parallel, spaced apart glass substrates;
a plurality of spacers arranged to help maintain the first and second substrates in substantially parallel, spaced apart relation to one another;
an edge seal sealing together the first and second substrates; and
an anticondensation coating provided on an exterior surface of the first substrate exposed to an environment external to the skylight, the anticondensation coating comprising the following layers moving away from the first substrate;
a layer comprising silicon oxynitride,a transparent conductive layer comprising indium-tin-oxide (ITO), andanother layer comprising silicon nitride,wherein the anticondensation coating has a hemispherical emissivity of less than 0.23 and a sheet resistance of less than 30 ohms/square.

Abstract
Certain example embodiments of this invention relate to articles including anticondensation coatings that are exposed to an external environment, and/or methods of making the same. In certain example embodiments, the anticondensation 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.

6. A window comprising:
-
a coating supported by a glass substrate, wherein the coating is an anticondensation coating comprising the following layers moving away from the glass substrate; a dielectric layer comprising silicon oxynitride, a transparent conductive layer comprising indium-tin-oxide (ITO), a layer comprising silicon nitride, and wherein said layer comprising ITO is located between and directly contacting said dielectric layer comprising silicon oxynitride and said layer comprising silicon nitride, wherein the anticondensation coating is disposed on an exterior surface of the substrate such that the anticondensation coating is exposed to an external environment, and the anticondensation coating has a hemispherical emissivity of less than 0.23 and a sheet resistance of less than 30 ohms/square. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14)
