Patent ID: 8287701

Claim:
A method of making a spandrel panel, the method comprising: providing a glass substrate; sputter-depositing a layer comprising titanium oxide on the glass substrate; sputter-depositing a layer comprising silicon nitride on the glass substrate over at least the layer comprising titanium oxide; thermally tempering the glass substrate with the layers comprising titanium oxide and silicon nitride thereon, so that the article has a Î”E* g value of no more than 6.0 due to the thermal tempering; after said thermal tempering, applying an opaque overcoat layer on the substrate over at least the layers comprising titanium oxide and silicon nitride, wherein the opaque overcoat layer directly contacts the layer comprising silicon nitride or an optional primer layer which may be provided on the layer comprising silicon nitride; and wherein after said tempering the glass substrate having the layer comprising titanium oxide and the layer comprising silicon nitride thereon, before the opaque overcoat layer is applied, has a visible transmission of from about 65-90%.
