1. A material comprising a transparent substrate coated with a stack of thin layers comprising at least one silver-based functional metallic layer and at least two dielectric coatings, each dielectric coating including at least one dielectric layer, so that each silver-based functional metallic layer is disposed between two dielectric coatings,
wherein the stack comprises, in the following order starting from the substrate:
a first silicon nitride layer;
a first crystallized zinc oxide layer in contact with the first silicon nitride layer and having a first thickness from 1.0 nm to 8.0 nm;
a silver-based functional metallic layer in contact with the first crystallized zinc oxide layer or separated from the first crystallized zinc oxide layer by a blocking underlayer having a thickness from 0.1 nm to 5.0 nm;
a nickel chromium-based metallic layer in contact with the silver-based functional metallic layer and having a thickness from 0.1 nm to 5.0 nm;
a zinc-based metallic layer in contact with the nickel chromium-based metallic layer;
a second crystallized zinc oxide layer in direct contact with the zinc-based metallic layer and having a second thickness from 1.0 nm to 8.0 nm, and
a second silicon nitride layer in contact with the second crystallized zinc oxide layer,
wherein a total thickness separating the first silicon nitride layer from the silver layer is from 1 nm to 13 nm.
