Abstract
A method of producing a vacuum between two glass sheets to form an insulating glazing. One of the sheets has a hole drilled in its thickness. Spacers are placed between the two glass sheets with the sealing joint being placed around the periphery of the sheets. A vacuum is created between the sheets through the hole which is then closed. The spacers are fixed on one of the sheets by bonding with a mineral compound covering at least the bonding zones on the glass sheet. The second sheet is placed on the spacers and on the peripheral sealing joint. The peripheral sealing and the bonding with the spacers are simultaneously effected by raising the temperature.
