Glazing assembly comprising a substrate provided with a stack of thin layers for solar protection and/or thermal insulation

A glazing assembly is provided made of at least one transparent substrate having a stack thereon that includes an alternation of n functional layers and n+1 coatings, wherein the functional layers have reflection properties in the infrared and/or solar radiation and wherein n.gtoreq.1 and where, in order to maintain the quality of the stack when the substrate is subjected to a heat treatment step, at least one of the following must be satisfied:

Glazing assembly comprising a substrate provided with a stack of thin

The subject of the invention is a glazing assembly comprising at lest one transparent substrate provided with a stack of thin 'A' layers composed in succession of a first coating of dielectric material, a first 'functional' layer having reflection properties in the infrared, in particular a metallic layer, and a third coating of dielectric material. The sum of the thicknesses of the first and second functional layers is greater than or equal to 25 nm. The ratio of the thickness of the first functional layer to the thickness of the second functional layer is less than 0.55.
