High light transmission, low-e sputter-coated layer systems and insulated glass units made therefrom

摘要

A high visible light transmitting, low-E sputter coated glass article, achieving neutral color and non-mirror-like appearance, useful in 2-pane and 3-pane IG units is achieved by an intermediate layer of silver, an undercoat of a metal oxide or nitride having an index of refraction of 2.35-2.75, and an overcoat of a metal oxide or nitride having an index of refraction of 1.85-2.25.
