A double-sided self-adhering barrier layer (9) comprising a barrier layer (4), a first adhesive layer (3) covering at least a portion of an upper major surface of the barrier layer (4), a second adhesive layer (5) covering at least a portion of the lower major surface of the barrier layer (4),
- wherein the double-sided self-adhering barrier layer (9) further comprises a single release liner,
- wherein the single release liner covers at least a portion of the outer major surface of the first adhesive layer (3) facing away from the barrier layer (4) and at least a portion of the outer major surface of the second adhesive layer (5) facing away from the barrier layer (3).
A kit-of-parts comprising:
- i. A double-sided self-adhering barrier layer (9) comprising a barrier layer (4), a first adhesive layer (3) covering at least a portion of an upper major surface of the barrier layer (4), a second adhesive layer (5) covering at least a portion of the lower major surface of the barrier layer (4) and
- ii. A roofing membrane (10) comprising a waterproofing layer (2) comprising at least one polymer P1,
- wherein the double-sided self-adhering barrier layer (9) further comprises a release liner, wherein the release liner covers at least a portion of the outer major surface of the first adhesive layer (3) facing away from the barrier layer (4) and at least a portion of the outer major surface of the second adhesive layer (5) facing away from the barrier layer (4).
