Abstract
The invention has as its subject a glass substrate provided with a conducting, low-emissivity transparent functional film, based upon metal oxide or oxides, on which is deposited an "outer" coating, the optical thickness of which is approximately one-quarter of the mean wavelength of the visible range, and preferably centered on 550 nm. In addition, an intermediate coating is provided between functional film and substrate, said coating having an optical thickness of from 50 to 100 nm, and preferably from 50 to 75 nm.
