Beschreibung
Zusammenfassung:	Production of a vacuum between two glass sheets making up an insulating window, one of these glass sheets incorporating a hole pierced through its thickness, is characterised in that a piece of low melting point alloy is placed at the outer end of the hole, the vacuum is produced and the alloy is melted so that it seals the wall of the hole in a manner that obstructs the hole. An insulating window produced by this method is also claimed. L'invention concerne un procédé pour réaliser le vide entre deux feuilles de verre constituant un vitrage isolant, l'une des feuilles de verre comportant un trou percé dans son épaisseur.Selon l'invention, on place une pièce d'alliage à bas point de fusion à l'extrémité externe du trou, on réalise le vide et on fond la pièce d'alliage pour la sceller sur la paroi du trou de façon à obstruer ledit trou.
