INSULATING GLASS (IG) WINDOW UNIT INCLUDING HEAT TREATABLE COATING WITH SPECIFIC COLOR CHARACTERISTICS AND LOW SHEET RESISTANCE

摘要

An insulating glass (IG) window unit, or other suitable window unit, includes a glass substrate with a coating thereon. The coating includes a lower contact layer based on zinc oxide and/or at least one silicon nitride inclusive layer that is Si-rich (i.e., non-stoichiometric). Using such a design, it has been found that coloration can be adjusted in order to achieve certain desirable optical characteristics.
