Abstract

Le but de la présente invention est de fournir un verre multicouche qui a une résistance suffisante pour constituer une porte ou une fenêtre sans châssis et qui peut garantir des propriétés d'isolation thermique.　L'invention concerne un verre multicouche dans lequel au moins deux plaques de verre sont disposées à distance l'une de l'autre avec un élément d'espacement interposé entre ces dernières et une couche creuse est formée dans un espace vide entre les plaques de verre. Dans le verre multicouche, un élément de renforcement est disposé à la périphérie de l'espace vide formé entre les plaques de verre et un côté bord extérieur des plaques de verre par rapport à l'élément d'espacement. L'élément de renforcement présente une résistance élastique supérieure à celle des plaques de verre, et comprend un matériau plastique renforcé par des fibres. Selon cette configuration, la résistance du verre multicouche peut être améliorée et les propriétés d'isolation thermique peuvent être garanties.
