Abstract: The invention relates to a spacer for panes (20) of multilayer insulation glazings, particularly for use in windows, doors, or similar. Said spacer consists of a hollow profile that is filled with a moisture-absorbing material. In order to obtain a good seal with a low quantity of sealant in the peripheral bond, the spacer is provided with webs (3) which protrude from the rear wall (5) of the hollow profile. Such a web (3) delimits a space (24) for receiving a sealant along with a disk that is adjacent to said web (3). No sealant needs to be applied to the outer surface (17) of the rear wall (5).
