Abstract
A low emissivity coatingincludes a plurality of phase adjustment layers; a first metal functional layer; and a second metal functional layerlocated over and spaced from the first metal functional layer. A ratio of the geometric thickness of the first metal functional layer divided by the geometric thickness of the second metal functional layer is in the range of 0.6 to 1. The low emissivity coatingprovides a reference IGU summer/day SHGC of at least 0.4 and a reference IGU winter/night U factor of no greater than 0.4 BTU/hr-ft-° F. (2.27 W/m2-K).
