Dual silver layer low-e glass coating system and insulating glass units made therefrom

The scattered glass of the present invention consists of a glass substrate and a coating system therein. The coating system extends from the glass a) a Si3N4 layer, b) a nickel or nichrome layer, c) a silver layer, d) a nickel or nichrome layer, e) a Si3N4 layer, f) a nickel ornithrome layer, g) a silver layer, h a nickel or nicotine layer and i) Si3N4 layer. If the glass substrate has a thickness of 2 to 6 mm, the scattered glass has a transmittance of at least 70% in the visible range, with a normal emission of 0.02 to 0.09, a hemispheric emission of 0.03-0.12, a layer resistance of 2-10? . The subject matter of the invention is also heat insulating glazing comprising at least two substantially parallel, spaced glass sheets, wherein at least one glass sheet is the above-scattered glass. ŕ
