摘要
A sputter-coated layer system on a glass substrate particularly useful in insulating glass (IG) units, enables normal emissivity values (E.sub.n) of 0.06 or less, good durability and neutral color. The layer system includes an undercoat of a transparent dielectric having an index of refraction between 2.5-2.6 at a wavelength of 550 nanometers, two layers of Si.sub.3 N.sub.4, and two layers of nichrome sandwiching a layer of silver to achieve its unique low-E, neutral color, non- mirrorlike solar management properties. An optional overcoat of a transparent dielectric material having an index of refraction of 2 at a wavelength of 550 nanometers may be provided.
