Condensation water-free insulation system for passenger aircraft

An insulation arrangement for thermally and acoustically insulating an aircraft fuselage, which comprises at least one insulation packet arranged on an exterior skin of the aircraft. The insulation packet includes dimensionally rigid foam, and comprises a shape corresponding at least with a structural component on the exterior skin, as the result of which the insulation packet is retained on the structural component even without any additional attachment elements. As a result, ventilation openings need not be provided, thereby reducing condensation water accumulating in aircraft insulation.
