Abstract

A sealing element, in particular for sealing a frame element with respect to a building component, having a sandwich structure, including: a metallic primary layer which is creped at least in certain regions to form an elongation reserve of the sealing element; a secondary layer; and a bitumen-including filling layer which is arranged between the primary layer and the secondary layer.

First claim

What is claimed is:

1. A sealing element with sandwich structure, the sealing element comprising:
a metallic primary layer which has been creped at least in some regions in order to form an elongation reserve of the sealing element;
a secondary layer; and
a fill layer comprising bitumen arranged between the primary layer and the secondary layer,
wherein the fill layer comprises a filler material, and a proportion of the filler material is 50% to 80% of the fill layer.

2. The sealing element as claimed in claim 1 , wherein the secondary layer is:
at least one of metallic and has been creped at least in some regions, or
an adhesive layer.

3. The sealing element as claimed in claim 1 , wherein a thickness, measured in a layering direction, of at least one of the primary layer and the secondary layer is 0.02 to 0.1 mm.

4. The sealing element as claimed in claim 1 , wherein the density of the fill layer is between 1.9 and 3.5 g/cm 3 .

5. The sealing element as claimed in claim 1 , wherein, in a layering direction, the fill layer is thicker than at least one of the primary layer and the secondary layer.

6. A process for the production of a sealing element with a sandwich structure, the process comprising the steps of:
providing a metallic primary layer and a secondary layer;
creping the metallic primary layer; and
after creping the metallic primary layer, joining the metallic primary layer and the secondary layer with a fill layer comprising bitumen arranged between the primary layer and the secondary layer to form the sandwich structure,
wherein the fill layer comprises a filler material, and a proportion of the filler material is 50% to 80% of the fill layer.

7. The process as claimed in claim 6 , wherein a degree of creping established during creping of the metallic primary layer is greater than a final degree of creping of the primary layer on the finished sealing element.

8. The process as claimed in claim 6 , wherein, during the joining procedure, at least one of the fill layer is laminated onto the metallic primary layer and the sandwich structure is edge-crimped.
