Certain example embodiments of this invention relate to insulating glass (IG) units including three substantially parallel spaced apart glass substrates, wherein at least two of the surfaces include low-emissivity (low-E) coatings and at least some of the non-low E coated surfaces have antireflective (AR) coatings disposed thereon. In certain example embodiments, low-E coatings are provided on the second and fifth surfaces of the IG unit, and each internal surface of the IG unit that does not support a low-E coating does support an AR coating. Additional AR coatings may be provided on one or both of the outermost surfaces in certain example embodiments. In some cases, the center substrate need not be heat treated because of the reduced absorption enabled by providing the low-E coatings on the two outermost substrates, as well as the reduced heat accumulation in the center lite itself and in the two adjacent spacers.

Insulating glass units with low-E and antireflective coatings, and/or methods of making the same

This invention relates to a coated article including a low-emissivity (low-E) coating. In certain example embodiments, the low-E coating is provided on a substrate (e.g., glass substrate) and includes at least first and second infrared (IR) reflecting layers (e.g., silver based layers) that are spaced apart by contact layers (e.g., NiCr based layers) and a dielectric layer of or including a material such as silicon nitride. In certain example embodiments, the coated article has a low visible transmission (e.g., no greater than 60%, more preferably no greater than about 55%, and most preferably no greater than about 50%).

Coated article with low-E coating having low visible transmission which may be used in IG window unit for grey appearance

A coated article is provided, having a coating supported by a glass substrate where the coating includes at least one color and/or reflectivity-adjusting absorber layer. The absorber layer(s) allows color tuning, and reduces the glass side reflection of the coated article and/or allows sheet resistance of the coating to be reduced without degrading glass side reflection. In certain example embodiments the absorber layer is provided between first and second dielectric layers which may be of substantially the same material and/or composition. In certain example embodiments, the coated article is capable of achieving desirable transmission, together with desired color, low reflectivity, and low selectivity, when having only one infrared (IR) reflecting layer of silver and/or gold. Coated articles according to certain example embodiments of this invention may be used in the context of insulating glass (IG) window units, monolithic windows, or the like.
