The invention relates to a barrier sheet (1) comprising an elongated windproof membrane (2), a wind, water and radon-proof adhesive layer (3), and an elongated radon-proof membrane (4). It also relates to a method for manufacturing a barrier sheet (1) comprising an elongated windproof membrane (2), a wind, water and radon-proof adhesive layer (3), and a radon-proof membrane (4), comprising the steps of; providing an elongated windproof membrane (2), an elongated radon-proof membrane (4) and an adhesive substance (9), advancing the windproof membrane (2) while applying adhesive substance (9) to the middle section (10) of the windproof membrane (2), applying a protective sheet (7) to at least the adhesive substance, cooling the barrier sheet (1), and applying adhesive substance (3) to a first side area (5) of the radon-proof membrane, the adhesive substance being coherent with at least a part of the adhesive substance being applied to the windproof membrane (2) so that the first side area (5) of the radon-proof membrane is connected to the windproof membrane (2). The invention further relates to the use of the above barrier sheet and a method for providing radon gas protection in a building comprising the steps of; covering the inner surfaces of a basement with radon membrane, arranging a barrier sheet (1) comprising an elongated windproof membrane (2), a wind, water and radon-proof adhesive layer (3), and a radon-proof membrane (4) between the walls of the basement and the framework of a building, and connecting the radon-proof membrane (4) to the radon membrane. |
