Abstract: A multi-layer façade film having a fleece layer and two plastic film layers, the fleece layer being sandwiched between the plastic film layers and bonded thereto. Each layer is elastically extensible in all directions. The fleece is made of a thermoplastic elastomer in a melt-blown process. Each film layer includes an elastically deformable thermoplastic urethane and is connected to the fleece as an extrusion coating. The façade film has a yield strength of at least 40% in the length and width directions of the film. A 50 mm wide film strip has a tensile strength of at least 120 N, a maximum Sd value of 1.5 m for vapor permeability, and a value corresponding to a water column of at least 8 m for water impermeability.
