Abstract:
Method for producing a vacuum between two sheets of glass constituting insulating glazing, one of the two sheets of glass including a hole pierced through its thickness, comprising, after having deposited spacers between the two sheets of glass, a peripheral sealing joint at a periphery of the two sheets of glass, forming the vacuum and stopping up the hole, whereby the spacers are fixed onto one of the two sheets of glass by bonding with an inorganic compound covering at least bonding areas on said one of the two sheets of glass, whereby another one of the two sheets of glass is deposited on the spacers and the peripheral sealing joint, and whereby a peripheral sealing step and the bonding step with the inorganic compound are carried out simultaneously by raising a temperature thereof.
