Abstract

Disclosed is a plastic sheet (10), which is water-resistant and water-vapor permeable, consisting of at least two permanently connected sheet layers (12, 14), wherein the first sheet layer (12) is made of a plastic material enabling the transmission of water vapor through chemical pathways by absorption/description. The second sheet layer (14) is provided with mineral additives (16) forming capillaries (18) between the plastic material and the mineral additives during expansion on the phase transition limits, which extend throughout the second sheet layer and enable the transmission of water vapor by physical pathways.
