Abstract
The present invention refers to a sealing element, particularly for the sealing of joints, having a foam element which is elastically expandable with delay as a result of impregnation and a substantially air-tight cover. In order to obtain improved tightness of the seal while retaining the advantageous ability of use of such a sealing element, the cover forms an open region within which the foam element is exposed.
