Glass article having a solar control coating
First Claim
1. A coated glass article comprising:
- (a) a glass substrate, having a surface;
(b) an iridescence-suppressing interlayer deposited on and adhering to the surface of the glass substrate;
(c) a first transparent coating deposited on and adhering to the iridescence-suppressing interlayer; and
(d) a second transparent coating deposited on and adhering to said first transparent coating, said first transparent coating and said second transparent coating having a difference in refractive indices in the near infrared region greater than a difference in refractive indices in the visible region, wherein the coatings, including the interlayer, are such as to provide, when applied to a clear nominal 3 mm glass substrate, a glass article having a visible light transmittance (Illuminant C) of at least 10 percentage points higher than a solar heat transmittance integrated with an air mass 1.5.

Abstract
A glass article having a solar control coating is disclosed for use in producing heat reducing glass for architectural windows. The coated article includes a glass substrate, an iridescence-suppressing interlayer deposited on and adhering to the surface of the glass substrate. At least a first transparent coating deposited on and adhering to the surface of the iridescence-suppressing coating and at least a second transparent coating deposited on and adhering to the surface of the first transparent coating. The first transparent coating and the second transparent coating have a difference in refractive indices in the near infrared region greater than a difference in the refractive indices in the visible region. The use of the article in architectural glazing results in a glazing that rejects solar energy in the near infrared region while permitting the transmittance of a high degree of visible light.
