| abstract |
The invention relates to a vapor permeable laminate (1) having at least one first cover layer (2) and at least one second cover layer (3), wherein the cover layers (2, 3) have perforations (4, 5) and are connected to one another in such a way that the Perforations of the first cover layer (2) do not overlap with the perforations (5) of the second cover layer (3), and wherein between the cover layers (2, 3) a structure (6) having pores (7) is provided. To achieve a sufficient vapor permeability while sufficient hydrostatic tightness is provided that the pores (7) each have a clear cross-sectional area (A) of less than 200 microns2. |
