Conventional insulating double-glazing unit and vacuum double-gazing unit do not have sufficient insulating property and the thickness of an insulating/double-glazing unit must be increased to improve the insulating property. The insulating/double-glazing unit according to this invention includes a first vacuum double-glazing unit (2) equipped with two sheets of flat glass (3 and 4) whose peripheries are sealed, which have multi-layered spacers (5) sandwiched between them and whose intermediate part is rendered vacuum, and a second vacuum double-glazing unit (2) or ordinary flat glass (10) whose periphery is sealed by a sealant (12) and which is laminated on the first vacuum double-glazing unit (2) with a gap between them. Because dry air or a rare gas is sealed between these sheets of flat glass, the insulating property can be improved without increasing the overall thickness of the insulating double-glazing unit.

Une unité de double vitrage isolante et une unité de double vitrage à vide classiques n'ont pas une propriété isolante suffisante et il convient d'augmenter l'épaisseur d'une unité isolante/de double vitrage afin d'améliorer la propriété isolante. L'unité isolante/de double vitrage de cette invention comprend une première unité de double vitrage à vide (2) dotée de deux plaques de verre plat (3 et 4) dont les périphéries sont hermétiques, entre lesquelles sont pris en sandwich des éléments d'espacement (5) multicouches et dont la partie intermédiaire est rendue vide, ainsi qu'une seconde unité de double vitrage à vide (2) ou un verre plat ordinaire (10) dont la périphérie est rendue hermétique par un agent d'étanchéité (12), et laquelle est stratifiée sur la première unité de double vitrage à vide (2) avec un espace intermédiaire. Etant donné que de l'air sec ou un gaz rare est enfermé hermétiquement entre ces deux plaques de verre plat, on peut améliorer la propriété isolante sans augmenter l'épaisseur globale de l'unité de double vitrage isolante.
