SUBSTRATE PROVIDED WITH A STACK HAVING THERMAL PROPERTIES AND HAVING A METAL TERMINAL LAYER

摘要

The invention relates to a substrate (10) coated on one face (11) with a stack of thin layers (14) having reflective properties for infrared and/or solar radiation comprising at least one metal functional layer (140), in particular made from silver or from a metal alloy containing silver, and at least two anti-reflective coatings (120, 160), said coatings each comprising at least one dielectric layer (122, 164), said functional layer (140) being disposed between the two anti-reflective coatings (120, 160), said stack further comprising a terminal layer (168) that is the layer of the stack that is the furthest from said face (11), characterised in that said terminal layer (168) is a metal layer consisting of zinc and tin, made from SnxZny with a ratio of 0.1 ≤ x/y ≤ 2.4 and having a physical thickness of between 0.5 nm and 5.0 nm, excluding said values, or indeed of between 0.6 nm and 2.7 nm, excluding said values.
