  • roofing membranes are known to be installed under the tile or slate of steep roofs as protection against flying snow, splash water, dust and the like.
  • roofing membranes should on the one hand be impermeable to water and on the other hand permeable to air and steam. In addition, they should have a high strength, in particular a high tear resistance, in order to be able to absorb the weight of the roofer, for example in the event of an accident.
  • roofing membranes made of lattice-proven foils are widespread. Although these films have good tear strength, the tear resistance and often also the vapor permeability remain unsatisfactory.
