Title: SUBSTRATE COMPRISING A STACK HAVING THERMAL PROPERTIES
Abstract:
The invention relates to a substrate (10), especially a transparent glass substrate, provided with a stack of thin films comprising a functional layer (40) which has infrared reflectance and/or solar radiation reflectance properties and is especially metallic based on silver or a metallic alloy containing silver, and two coatings (20, 60), said coatings consisting of a plurality of dielectric layers (24, 26; 64) such that the functional layer (40) is arranged between the two coatings (20, 60), the functional layer (40) being arranged on a wetting layer (30) which is arranged in turn directly on a subjacent coating (20). The inventive substrate is characterised in that the subjacent coating (20) comprises at least one dielectric layer (24) based on a nitride, especially silicon nitride and/or aluminium nitride, and at least one non-crystallised mixed oxide smoothing layer (26) in contact with the subjacent wetting layer (30).
