Abstract

A door or wall of an environmental chamber and in particular a glazed door or wall includes an insulating panel. The insulating panel includes at least two glass substrates between which a vacuum has been created. The at least two glass substrates being separated from each other by mounts distributed over the entire surface of the at least two glass substrates. The at least two glass substrates joined together around their periphery by an inorganic seal.

Claims
