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.

Sealing element

The present invention relates to a sealing element of foam of delayed elastic resilience as a result of impregnation, in which, in order to obtain improved properties, on each cross-sectional plane (2) the delayed resilience is inherent in only a part of the elastically resilient volume and the remaining part (4) of the elastically resilient volume consists of closed-cell foam.
