1. A visually neutral reflectance, high transmittance, low emissivity article comprising:
- a. a transparent nonmetallic substrate;
b. a first transparent antireflective metal oxide film having a refractive index of about 2.0 deposited on a surface of said substrate;
c. a transparent metal oxide layer having a refractive index greater than 2.0 deposited on said first antireflective metal oxide film;
d. a transparent infrared reflective metallic film deposited on said metal oxide layer;
e. a transparent metal layer deposited on said infrared reflective metallic film; and
f. a second transparent antireflective metal oxide film deposited on said metal layer.
