A method of making an insulating glass (IG) window unit includes: having a coated article including a multi-layered low-E coating on a glass substrate; at least two flexible protective sheets adhered to a top surface of the low-E coating via at least an adhesive layer, and a protective coating over the low-E coating and/or over at least one of the flexible protective sheets in order to substantially fill one or more gaps formed between the low-E coating and the flexible protective sheet(s) and/or between the flexible protective sheets; and following cutting, edge seaming, and/or washing, removing at least part of the temporary protective coating by peeling the protective sheets off and removing at least part of the protective coating when peeling off the protective sheets.

Method of making coated glass article, and intermediate product used in same

In certain example embodiments of this invention, there is provided a method of making a window, the method including: forming a multi-layered low-E and/or solar control coating on a glass substrate; providing at least two flexible protective sheets in non-liquid form to the glass substrate over at least part of the low-E and/or solar control coating; applying at least one protective coating in liquid form, before and/or after the flexible protective sheets are provided, so as to reduce one or more gaps formed between the low-E and/or solar control coating and the flexible protective sheet(s) and/or between the flexible protective sheets; and performing one or more of cutting, edge seaming, and/or washing the coated article with the protective coating and protective sheets thereon and peeling the protective sheets and at least part of the protective coating off of the top surface of the low-E and/or solar control coating. Heat treatment (e.g., thermal tempering) may then be performed, and the heat treated coated article may be used in a window unit or the like.
