Low emission expansion joint assembly

Abstract

The invention relates to an expansion joint assembly (1) adapted for flexibly connecting first and second duct ends. The expansion joint comprises an expansion joint layer (2), a fastening assembly (3) adapted for attachment at the first duct end (41) and at the second duct end (42), and a metal foil (5). Thereby the assembly (3) at the first duct end (41) fixes a first end (21) of the expansion joint layer (2) between a first face (31) and a second face (32) and the fastening assembly at the second duct end fixes a second end (22) of the expansion joint layer (2) between a first face (31) and a second face (32). Furthermore the metal foil (5) encloses at least one end of the expansion joint layer (2) between the first face (31) and the second face (32), so that the metal foil (5) overlays the expansion joint layer (2) radially inwards, radially outwards and at the axial end.
