PARTITION

The invention relates to a partition () for sealing and/or supporting a cavity, comprising a carrier () and an expansion material () arranged on the carrier (), which expansion material can be transferred from an initial state to an expanded state by means of activation, wherein the carrier () comprises at least one compensation element (), which provides variability of the effective sealing surface () of the carrier (), such that a change in the effective sealing surface () of the carrier () can be brought about by means of a force acting on the carrier (), a limiting element () being provided, by means of which a movement of at least one portion of the carrier () which accompanies the change in the effective sealing surface () is limited.
