Insulating glass panel and method for producing the same

Method of producing an insulating glass panel in which two separate glass panes are kept at a distance by a spacer formed from a hollow section bar, which has an inner surface, an outer surface and two flanks,

• a drying agent is provided in combination with the spacer,
• and a gap is provided on both sides of the spacer between the spacer and the two glass panes which gap is sealed by a primary sealing compound that adheres to the spacer and to the glass panes,
• a compound, which contains a drying agent, is arranged beside the primary sealing compound that seals the two gaps, on the side of the spacer, hereinafter also described as the inside, that faces the inner surface of the insulating glass panel, comprising the steps of:
• (a) Providing a section bar having a hollow cross-section;
• (b) applying a compound containing a drying agent, on the section bar, on the side of the spacer which later forms the inside of the spacer and
• applying a primary sealing compound on the flanks of the section bar so that the primary sealing compound, and the compound containing the drying agent are arranged one adjoining the other and the compound containing the drying agent comes to cover the inside of the spacer to the extent it is not covered by the primary sealing compound;
• (c) forming the coated section bar into the shape of a frame-like structure;
• (d) closing the frame-like structure to form a spacer by joining the ends of the section bar one to the other;
• (e) applying the spacer to the first glass pane so that it adheres to the pane in the neighborhood of the edge of the first glass pane;
• (f) applying a second glass pane to the spacer in parallel to the first glass pane so that the spacer adheres to the second glass pane as well;
• (g) compressing the two glass panes to the thickness predetermined for the insulating glass panel;
• (h) bonding, if necessary, the spacer to the two glass panes by application of a secondary sealing compound,
• wherein the order in succession of the operations of applying the primary sealing compound and of the compound containing the drying agent may be exchanged or the primary sealing compound and the compound containing the drying agent may be applied simultaneously or in time-overlapping fashion.

Method of producing an insulating glass panel in which two glass panes are firmly bonded one to the other and are sealed by at least one sealing compound, with a frame-like spacer positioned between them, comprising the steps of:

• (a) Producing a frame-like spacer from one or more hollow-section bars having a base, two flanks projecting from the base and one side which later faces the inner space of the insulating glass panel;
• (b) applying a rope of a compound containing a drying agent upon the side which later faces the inner space of the insulating glass panel;
• (c) applying the whole at least one sealing compound on the flanks of the one or more hollow-section bars of the spacer;
• and
• (d) bonding the spacer to the two glass panes,
• wherein the order in succession of the steps (a), (b) and (c) may be exchanged.
