Abstract
A transparent substrate provided with a covering multi-layer stack of thin coatings of which at least one is a metal coating (5) having low emissivity characteristics in the infrared positioned between two layers of the multi-layer stack, which are formed of a dielectric material, said multi-layer stack having at least one wetting layer below the metal coating (5), which wetting layer is based on tantalum oxide or niobium oxide.
