1. A glazing in the form of a window glass or vehicle glass, comprising:
a transparent substrate, and
a coating, comprising, in order outward from the transparent substrate;
optionally, a diffusion barrier layer,
a first anti-reflective layer,
optionally, a first seed layer,
a first functional metal layer,
optionally, at least one first blocker layer,
a second anti-reflective layer,
optionally, a second seed layer,
a second functional metal layer,
optionally, at least one second blocker layer,
a third anti-reflective layer,
optionally, a top layer,
wherein each anti-reflective layer has at least one dielectric layer,
wherein at least one of the first functional metal layer and the second functional metal layer comprises a Ag alloy consisting essentially of Ag and Al, and
wherein an Al content of the Ag alloy is 0.05-0.14 at %, the rest being Ag.
