Abstract
A vehicle glazing comprises a pane of tinted glass, tinted by at least 1.0 to 1.8% wt. of total iron, having a low emissivity coating on its interior surface. The coating has an emissivity from 0.05 to 0.4 and may include a transparent conductive oxide (and optionally a dopant), or a metal layer and at least one dielectric layer. The glass is preferably toughened glass. According to another aspect, a laminated glazing includes two plies of glass, with a sheet of interlayer material laminated between the two glass plies, and wherein at least one ply of glass or the sheet of interlayer material is body tinted. The glazing has a low emissivity coating on its interior surface, the inner ply may be clear glass or tinted glass, and the interlayer material may be clear PVB or tinted PVB, and may further be infra-red reflecting. Either of the glazings may be used as a roof or other vehicle glazing.
