ABSTRACT:
A high performance, durable, low-E glass exhibiting about 80% or more visible transmittance, a hemispherical emissivity (E.sub.h) of about 0.13 or less, and a normal emissivity (E.sub.n) of about 0.10 or less is formed by sputter-coating a layer system on the glass substrate which comprises an undercoat and overcoat of Si.sub.3 N.sub.4, at least one silver layer, and at least two sandwiching layers of a nickel or nickel alloy, preferably with the nickel alloy being nichrome, and the chromium being in the form of a nitride thereof.
