    Abstract: The invention relates to a sealing element (1) comprising: i. A waterproofing adhesive layer (2) having first and second major surfaces, ii. An adhesive layer (3) covering at least a portion of the first major surface of the waterproofing adhesive layer (2), and iii. A carrier layer (4) on the side of the waterproofing adhesive layer (2) opposite to the side of the adhesive layer (3), wherein the waterproofing adhesive layer (2) is composed of a self-adhering bituminous composition and the adhesive layer (3) is composed of a non- bituminous pressure sensitive adhesive. The invention also relates to use of the sealing element as a waterproofing, roofing, vapor barrier, vapor retarder, or a façade membrane, or as a waterproofing, roofing tape, or façade tape.
