'NEUTRAL HIGH PERFORMANCE, DURABLE LOW -E GLASS COATING SYSTEM, INSULATING GLASS UNITS MADE THEREFROM AND METHODS OF MAKING SAME'

摘要

A sputter-coated layer system on a glass substrate particularly useful in insulating glass (IG) units, enables normal emissivity values (En) of 0.06 or less, good durability and neutral color. The layer system includes two layers of Si3 N4 combined with a sufficient amount of stainless steel sandwiching a layer of silver to achieve its unique low-E, neutral color, non-mirrorlike solar management properties.
