A first coating is provided on a first side of a glass substrate, and a second coating is provided on a second side of the glass substrate, directly or indirectly. The coatings are designed to reduce color change of the overall coated article, from the perspective of a viewer, upon heat treatment (e.g., thermal tempering and/or heat strengthening) and/or to have respective reflective coloration that substantially compensates for each other. For instance, from the perspective of a viewer of the coated article, the first coating may experience a positive a* color value shift due to heat treatment (HT), while the second coating experiences a negative a* color shift due to the HT. Thus, from the perspective of the viewer, color change due to HT (e.g., thermal tempering) can be reduced or minimized, so that non-heat-treated versions and heat treated versions of the coated article appear similar to the viewer.

Heat treatable coated article having coatings on opposite sides of glass substrate

A coated article is provided for use in a surveillance window or the like. The coated article is a second surface one-way mirror that allows an observer(s) on an observer side to be able to see an object(s)/subject(s) on the opposite side of the coated article, but a viewer on the opposite side cannot reasonably see through the coated article to view things on the observer side of the coated article. The second surface mirror is designed to have a high glass side visible reflectance (RY), and an extremely low film side visible reflectance (RY), so that visible transmission (Tor TY) of the coated article is lower than the glass side visible reflectance but higher than the film side visible reflectance.

Coated article for use in surveillance window or the like and method of making same

A dielectric mirror includes a coating having alternating high and low index layers. The mirror coating has no metallic reflective layer of Al or Ag in certain example embodiments, and may have film side and/or glass side visible reflection of from about 50-90% (more preferably from about 60-80% and most preferably from about 65-75%) and visible transmission of from about 10-50% (more preferably from about 10-40% or 20-40%) in certain example embodiments.

This invention relates to a window designed to prevent or reduce bird collisions therewith. In certain example embodiments, the window may include an insulating glass (IG) window unit having first and second substrates spaced apart from one another, wherein at least one of the substrates supports an ultraviolet (UV) reflecting coating for reflecting UV radiation so that birds are capable of more easily seeing the window. By making the window more visible to birds, bird collisions and thus bird deaths can be reduced.
