Abstract
A transparent substrate comprises glass and is provided with a thin-film stack including a plurality of functional layers. The thin-film stack comprises at least three silver-based functional layers. The thin-film stack has a resistance R□<1.5 Ω per square. The transparent substrate may undergo at least one transformation operation involving a heat treatment at a temperature of at least 500° C., so as to make it possible to achieve, using the substrate, alternatively or cumulatively, thermal control and/or electromagnetic shielding and/or heating.
