Claim Text:
1. A window comprising: a coating supported by a glass substrate, the coating being exposed to an adjacent external environment, wherein the coating comprises the following layers moving away from the glass substrate: a transparent layer comprising indium-tin-oxide (ITO) having a physical thickness of from 75-175 nm, a dielectric layer comprising silicon and nitrogen and being doped with aluminum, and a dielectric layer comprising oxygen and aluminum, the dielectric layer comprising oxygen and aluminum being located directly on and contacting the dielectric layer comprising silicon and nitrogen, wherein said layer comprising ITO is located directly under and contacting said dielectric layer comprising silicon and nitrogen, wherein the layer comprising silicon and nitrogen is thinner than is the layer comprising ITO, wherein a visible transmission of the coating and the glass substrate is 80% or higher, and the coating has a sheet resistance of less than 30 ohms/square, and wherein said dielectric layer comprising oxygen and aluminum is an outermost layer of the coating and is exposed to the external environment.
