Abstract
A glazing includes a transparent substrate coated with a stack of thin layers including at least one functional metal layer and at least two antireflective coatings, each antireflective coating including at least one dielectric layer, so that each functional metal layer is positioned between two antireflective coatings. The stack includes at least one silver-based functional metal layer including at least 95.0% by weight of silver, with respect to the weight of the functional layer, and from 0.5 to 3.5% by weight of zinc, with respect to the weight of zinc and silver in the functional layer.
Claims22
A glazing comprising a transparent substrate coated with a stack of layers comprising at least one functional metal layer and at least two antireflective coatings, each antireflective coating comprising at least one dielectric layer, so that each functional metal layer is positioned between two antireflective coatings, wherein the stack comprises at least one silver-based functional metal layer consisting of:
- at least 96.5% by weight of silver, with respect to the weight of the functional layer, and
- from 0.5 to 3.5% by weight of zinc, with respect to the weight of zinc and silver in the functional layer.
