LOW SOLAR ABSORBING BLUE GLASS, SOLAR REFLECTING COATED BLUE GLASS, AND INSULATING UNIT HAVING A LOW SOLAR HEAT GAIN |
摘要 |
An insulating unit having a blue color and a solar heat gain coefficient less than 0.40 includes a clear glass sheet spaced from a coated glass sheet. The coated glass sheet includes a colored glass substrate having a solar infrared reflective coating. The composition of the coated substrate includes a base glass portion and a glass colorant portion, the glass colorant portion including total iron in the range of 0.04 to less than 0.28 weight percent; CoO in the range of 32 to 90 parts per million, and Se in the range of greater than 0 to less than 5.5 parts per million. In one non-limiting embodiment of the invention the glass substrate at a thickness of 0.223 inches has a* chromaticity coordinates of -3.5 to +2.5 and b* chromaticity coordinates of -1 to -15, and a visible light transmittance of 40 to 80%.
