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, includesa glass substrate with a coating thereon.The coating includes a lower contact layer based on zinc oxide and/or at leastone silicon nitride inclusive layer that is Si-rich (i.e.,non-stoichiometric). Using such a design, it has been found that colorationcan be adjusted in order to achieve certain desirableoptical characteristics.
