Claim:
A heat treatable coated glass pane with a low-e and/or solar control coating comprising—in sequence from the glass surface—at least the following layers: a lower anti-reflection layer, comprising a base layer of an (oxi)nitride of aluminium in contact with a middle layer of an oxide of Zn and Sn, and a top layer of an oxide of zinc; a silver-based functional layer; a barrier layer of an oxide or suboxide of NiCrOx; and an upper anti-reflection layer comprising a layer of an (oxi)nitride of aluminium having a thickness of more than 10 nm and an outermost protective layer that comprises 10-90 wt. % Zn and 90-10 wt. % Sn in wt. % of the total metal content, wherein the barrier layer is in contact with the layer of an (oxi)nitride of aluminium of the upper anti-reflection layer, which is in turn in contact with the outermost protective layer.
