Title
(EN) LOW-COST HIGH-PERFORMANCE VACUUM INSULATED GLASS AND METHOD OF FABRICATION
(FR) VERRE ISOLANT SOUS VIDE À HAUTE PERFORMANCE ET PEU COÛTEUX, ET PROCÉDÉ DE FABRICATION
Abstract
(EN)
A low-cost high-performance Vacuum Insulated Glass is produced with three glass panes and bonding fiber mesh structures embedded between the glass panes. Each mesh structure is configured with elongated bonding fiber elements arranged in a grid configuration. The bonding fiber elements are formed with a fiber core covered with a low melting temperature material. The low melting temperature material melts upon heating and creates numerous vacuum sealed cells between the glass panes. The fiber core does not melt, and remains intact bonded to the glass panes, thus creating a support mechanism for supporting the glass panes at a spaced apart relationship.

L’invention concerne un verre isolant sous vide à haute performance et peu coûteux, produit avec trois vitres et des structures en maille de fibres de liaison incorporées entre les vitres. Chaque structure en maille est composée d’éléments fibreux de liaison allongés agencés dans une configuration de grille. Les éléments fibreux de liaison sont pourvus d’un cœur fibreux recouvert d'un matériau à basse température de fusion. Le matériau à basse température de fusion fond lors du chauffage et crée de nombreuses cellules scellées sous vide entre les vitres. Le cœur fibreux ne fond pas, et reste intact et lié aux vitres, créant ainsi un mécanisme de support destiné à porter les vitres en une relation espacée.
