Patent ID: 8389077

Claim:
An IG window unit for reducing bird collisions comprising: a first glass substrate; a second glass substrate spaced apart from the first glass substrate; a UV reflecting coating provided on an exterior surface of the first glass substrate so as to directly contact the exterior surface of the first glass substrate at an exterior surface of the IG window unit so as to face an exterior of a building in which the IG window unit is to be mounted; a low-E coating comprising at least one IR reflecting layer comprising silver located between at least first and second dielectric layers, the low-E coating being provided on an interior surface of the first glass substrate so that the low-E coating and the UV reflecting coating are located on opposite sides of the first glass substrate for reducing bird collisions; wherein the UV reflecting coating is located at the exterior surface of the IG window unit and has an outer surface that is exposed to atmosphere; and wherein the IG window unit has a visible transmission of at least about 50%, and the UV reflecting coating reflects at least 20% of UV radiation in the range of from 350-450 nm.
