Leakage protection cladding for forming a double walled tank, wherein the Leakage protection cladding comprises knobbed metal foil (11), in particular knobbed aluminum foil with regularly arranged nubs (13) in strips (33)in which nubs (13) interchange with foil basal surface portion. Adjacent nubs (13) in adjacent strip portions (33) is offset to each other are arranged such that one knob (13) of a strip portion (33) on both sides of each two by a film basal surface portion (31) separate nubs (31) of an adjacent strip portion (33), thus reducing the risk of fractures formation. |
