A low-emissivity (low-E) coating on a substrate (e.g., glass substrate) 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), a layer comprising silicon nitride, and an absorber layer of or including a material such as niobium zirconium which may be oxided and/or nitrided. The absorber layer is designed to allow the coated article to realize glass side reflective (equivalent to exterior reflective in an IG window unit when the coating is on surface #2 of the IG unit) grey color. In certain example embodiments, the coated article (monolithic form and/or in IG window unit form) has a low visible transmission (e.g., from 20-45%, more preferably from 22-39%, and most preferably from 25-37%). In certain example embodiments, the coated article may be heat treated (e.g., thermally tempered and/or heat bent).

The invention relates to a process for obtaining a material comprising a substrate coated on at least one part of at least one of its faces with at least one functional layer, said process comprising: a step of depositing the or each functional layer, then a step of depositing a sacrificial layer on said at least one functional layer, then a step of heat treatment by means of radiation chosen from laser radiation or radiation from at least one flash lamp, said radiation having at least one treatment wavelength between 200 and 2500 nm, said sacrificial layer being in contact with the air during this heat treatment step, then a step of removing the sacrificial layer using a solvent, said sacrificial layer being a monolayer and being such that, before heat treatment, it absorbs at least one part of said radiation at said at least one treatment wavelength and that, after heat treatment, it is capable of being removed by dissolution and/or dispersion in said solvent.

A window is designed to prevent or reduce bird collisions therewith. In certain example embodiments, the window may be an insulating glass (IG) window unit, or alternatively a monolithic window. In IG window unit embodiments, the IG window unit includes first and second substrates (e.g., glass substrates) spaced apart from one another, wherein at least one of the substrates supports both a patterned ultraviolet (UV) absorbing coating for absorbing UV radiation, and a UV reflecting coating for reflecting UV radiation, so that a more contrasting UV image is emitted/seen and birds are capable of more easily seeing the window and avoiding collisions therewith. By making the window more visible to birds, bird collisions therewith and bird deaths can be reduced.
