Solar control glazing

摘要

A sheet of vitreous material bearing a multilayer solar control lamination that includes at least one functional layer based on a material that reflects infrared radiation surrounded by dielectric coatings and at least one 4 nm thick absorbent layer formed by at least one oxide or oxynitride of a cobalt- and/or copper-based alloy. The sheet of vitreous material may be applied to solar control glazing units having multiple glazings.

1. A sheet of vitreous material bearing a multilayer solar control lamination, said lamination comprising:
a functional layer; a dielectric coating below the functional layer; a dielectric coating above the functional layer; and an absorbent layer, wherein the functional layer comprises a material that reflects infrared radiation, wherein the absorbent layer has a thickness of at least 4 nm, wherein the absorbent layer comprises at least one oxide or oxynitride of an alloy comprising at least 20 atom % cobalt and/or copper, and wherein the alloy comprises cobalt-tin, cobalt-titanium, copper-aluminium, cobalt-chromium, copper-zinc, copper-tin, copper-cobalt, copper-titanium, cobalt-copper, or mixtures thereof.
