Patent ID: 7875357

Claim:
A coated glass article comprising: a dielectric substrate; a first dielectric metal oxide layer deposited over the dielectric substrate, the first dielectric metal oxide layer comprising an oxide of tin or titanium; a first highly conductive silver free metal oxide layer deposited over the first dielectric metal oxide, the highly conductive metal oxide comprising an oxide of rhenium or ruthenium, having a thickness <1,000 Å and an electrical conductivity greater than 10,000 ohm −1 cm −1 ; and a second dielectric metal oxide layer deposited over the conductive, silver-free metal oxide layer, the second dielectric metal oxide layer comprising an oxide of tin or titanium; wherein the coated glass article has an emissivity of 0.3, a visible light transmittance >70%, and a total solar energy transmittance of <60%.
