Abstract
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.
