  • Publication number: 20080152848
    Abstract: The invention relates to an insulating glass pane, in which two separate glass panes (2, 3) are held at a distance from one another by a spacer (4), which consists of a strip and which has an inner side (12), and outer side (6) and two flanks (11). A drying agent is provided in conjunction with the spacer (4), and a gap is provided on both sides of the spacer (4) between the spacer and both glass panes (2, 3). This gap is sealed by a primary sealing compound (19) that adheres to the spacer (4) and to the glass panes (2, 3). This invention provides that a compound (18), which contains a drying agent is supplies to the primary sealing compound (19) that seals both gaps and, afterwards, to the side (12) of the spacer (4) (also referred to as inner side (12) hereafter), this side facing the inner space (17) of the insulating glass pane. Said compound (18) is applies so that it covers the inner side (12), that is, as long as the inner side is not already covered by the primary sealing compound (19).
