A double glass in which the interval between the glass plates can be reliably held without sacrifice of design. In the double glass (10), a member (20) for holding the interval between two glass plates is fitted in an interstice (18) with a recess-like cross-section defined by the inner sides of the circumferential edge of the opposite glass plates (12, 12) and by the outer circumferential surface of a resin spacer (16). An outer side face (20A) of the interval holding member (20) is placed in flush with the circumferential edges (12A, 12A) of the two glass plates (12, 12) or placed slightly on the hollow layer side (14). The interval holding member (20) consists of a hard portion (22) with a rectangular cross-section inserted in the interstice between the glass plates (12, 12) and of soft portions (24) softer than the hard portion, the soft portions (24) being at those positions of the hard portion (22) which face the glass plates (12, 12) and made to be in intimate contact with the inner surfaces of the circumferential edges of the glass plates (12). The soft portions (24) are constructed to facilitate insertion of the hard portion (22) into the interstice (18) and to be less likely to come out of position.

L'invention concerne un double vitrage dans lequel l'intervalle séparant les plaques de verre peut être maintenu de manière fiable sans compromettre la conception. Dans le double vitrage (10), un élément (20) servant à maintenir l'intervalle entre deux plaques de verre est posé dans un interstice (18) avec une section transversale en retrait définie par les côtés internes du bord circonférentiel des plaques de verre opposées (12, 12) et par la surface circonférentielle externe d'une entretoise de résine (16). Une face latérale externe (20A) de l'élément de maintien d'intervalle (20) est placée en affleurement avec les bords circonférentiels (12A, 12A) des deux plaques de verre (12, 12) ou bien légèrement sur le côté de la couche creuse (14). L'élément de maintien d'intervalle (20) comprend en une portion dure (22) avec une section transversale rectangulaire insérée dans l'interstice entre les plaques de verre (12, 12) et des portions souples (24) plus souples que la portion dure, les portions souples (24) étant situées au niveau des parties de la portion dure (22) faisant face aux plaques de verre (12, 12) et établissant un contact étroit avec les surfaces internes des bords circonférentiels des plaques de verre (12). Les portions souples (24) sont construites pour faciliter l'insertion de la portion dure (22) dans l'interstice (18) et moins susceptibles de changer de position.
