joint-sealing strip (10) has two longitudinal sides (16, 18) as well as a top side (22) that borders on the one joint flank (20) in the installed state of the joint-sealing strip (10), and an underside (26) that borders on the opposite joint flank (24) in the installed state of the joint-sealing strip (10), wherein the membrane layer (14) or membrane layers (14) run(s) in the longitudinal direction (28) between top side (22) and underside (26), in each instance, as well as parallel to or almost parallel to the longitudinal sides (16, 18). ### Claim 3 (depends on 1) Joint-sealing strip (10) according to claim 1, wherein the composition of the membrane layer (14) or membrane layers (14), the arrangement of the membrane layer (14) or membrane layers (14), and/or the number of the membrane layers (14) are selected in such a manner that the joint-sealing strip (10) is tighter against water vapor in the region that borders on an atmosphere with high moisture than in the region that borders on an atmosphere with lower moisture. ### Claim 4 (depends on 1) Joint-sealing strip (10) according to claim 1, wherein the foam material (12) is a predominantly open-celled raw foam. ### Claim 5 (depends on 1) Joint-sealing strip (10) according to claim 1, wherein the foam material (12) is an impregnated, preferably a homogeneously impregnated raw foam. ### Claim 6 (depends on 1) Joint-sealing strip (10) according to claim 1, wherein the foam material (12) is a raw foam, preferably impregnated with acrylates in such a manner that the water vapor diffusion resistance of the impregnated foam material is less than the water vapor diffusion resistance of at least one membrane layer. ### Claim 7 (depends on 1) Joint-sealing strip (10) according to claim 1, wherein at least one membrane layer (14) is formed from an adhesive, preferably from an acrylate pressure-sensitive adhesive, or a mixture of an acrylate pressure-sensitive adhesive and a polyurethane adhesive. ### Claim 8 (depends on 1) Joint-sealing strip (10) according to claim 1, wherein at least one membrane layer (14) is formed from at least one water-resistant modified acrylate ### Claim 9 (depends on 1) Joint-sealing strip (10) according to claim 1, wherein at least one membrane layer (14) is formed from a modified polyamide film that is preferably glued to the foam material (12). ### Claim 10 (depends on 1) Joint-sealing strip (10) according to claim 1, wherein at least one membrane layer (14) is formed from a polyamide dispersion, preferably in the form of an adhesive. ### Claim 11 (depends on 1) Joint-sealing strip (10) according to claim 1, wherein at least one membrane layer (14) has a greater water vapor diffusion resistance than the foam material (12). ### Claim 12 (depends on 1) Joint-sealing strip (10) according to claim 1, wherein at least two membrane layers (14) have a composition that is different from one to the other. ### Claim 13 (depends on 1) Joint-sealing strip (10) according to claim 1, wherein the membrane layer (14) or membrane layers (14) is/are disposed within the foam material (12). ### Claim 14 (depends on 1) Joint-sealing strip (10) according to claim 1, wherein the membrane layer (14) or membrane layers (14) are permanently elastic. ### Claim 15 (depends on 14) Joint-sealing strip (10) according to claim 14, wherein the joint-sealing strip (10) has at least one membrane layer (14) on one or on both longitudinal sides (16, 18), in each instance, in addition to or in place of the membrane layers (14) that lie on the inside. ### Claim 16 (depends on 1) Joint-sealing strip (10) according to claim 1, wherein when using multiple membrane layers (14), these have the same and/or a different distance of 5 mm to 100 mm, from one another, in each instance, preferably between 5 mm and 13 mm or preferably between 14 mm and 20 mm or preferably between 21 mm and 30 mm or preferably between 31 mm and 100 mm. ### Claim 17 (depends on 1) Joint-sealing strip (10) according to claim 1, wherein the foam material sections (12a, 12b, 12c) that run in the longitudinal direction (28) and are divided by at least one membrane layer (14) are configured differently, in such a manner that the joint-sealing strip (10) is tighter against water vapor in the region that borders on an atmosphere with high moisture than in the region that borders on an atmosphere with lower moisture. ### Claim 18 (depends on 1) Joint-sealing strip (10) according to claim 1, wherein the foam material (12) is a PUR foam material, preferably soft PUR foam
