Claim:
1. A joint-sealing strip composed of foam material, wherein the joint-sealing strip has one or more moisture-variable membrane layers, wherein a water vapor diffusion resistance of the one or more moisture-variable membrane layers changes continuously depending on a surrounding moisture, such that a desired tightness of the joint-sealing strip adjusts itself depending on a surrounding moisture, wherein the composition of the one or more membrane layers, the arrangement of the one or more membrane layers, and/or the number of membrane layers are selected in such a manner that the joint-sealing strip is tighter against water vapor in a region that borders on an atmosphere with high moisture than in the region that borders on an atmosphere with lower moisture, and wherein the joint-sealing strip has two longitudinal sides as well as a too side that borders on a 1 pint flank in a installed state of the joint-sealing strip, and an underside that borders on an opposite joint flank in the installed state of the joint-sealing, wherein the one or more membrane layers run the longitudinal direction between the top side and underside, in each instance, as well, as parallel to or almost parallel to the longitudinal sides.
