Abstract
A glass spandrel coated on the inwardly glazed glass surface with a transparent heat reflective film and a black, opaque coating firmly adhered to and covering the exposed surface of the film. The opaque coating includes a light absorbing component to limit the visible light reflection from materials attached to or located behind the inwardly glazed coated surface below a critical value.
Claims9
An architectural panel consisting essentially of a transparent substrate, a transparent reflective coating disposed on a major surface of said substrate, a black opaque coating disposed over said transparent coating and including a light absorbing component dispersed therein in an amount sufficient to limit the Illuminant C diffuse reflectance of the panel when viewed from the uncoated surface of the substrate to not more than 0.3 percent, an adhesive applied to said opaque coating, and a layer of insulating material adhered to said adhesive.
An architectural panel consisting essentially of a heat strengthened transparent glass substrate, a transparent reflective coating disposed on a major surface of said substrate, a black opaque coating disposed over said transparent coating and substantially coextensive therewith, said opaque coating having carbon black particles dispersed therein in an amount sufficient to limit the Illuminant C glass side diffuse reflectance of the panel to not more than 0.15 percent, an adhesive applied to the exposed surface of said opaque coating, and a layer of insulating material adhered to said adhesive.
