SOLAR CONTROL GLAZING

摘要

A vehicle glazing comprising a pane of glazing material, an absorptive coating, which absorbs radiation of wavelength greater than 400 nm (and possibly up to 100 µm), on a first surface of the pane, and a low emissivity coating on the first surface, or a second surface, of the pane. The glazing may be used as a roof glazing. The absorptive coating may comprise either a) a metal, metal alloy or material based on a metal alloy, or b) at least one layer of a dielectric material and at least one layer of a metal or metal alloy. The low emissivity coating may comprise either a) a transparent conductive oxide (and optionally a dopant material), or b) at least one metal layer and at least one dielectric layer. Also disclosed in a laminated glazing comprising two plies of glazing material with a sheet of interlayer extending therebetween, an absorptive coating, as above, on a surface of one of the plies of glazing material, and a low emissivity coating on the interior surface of the glazing.
