The design and attachment of an insulation package near the fuselage structure to protect the cabin region of an aircraft against fire acting on the insulation package from outside the aircraft environment, thus clearly facilitating evacuation of the passengers from the vehicle. The insulation package arrangement may comprise several fuselage insulation packages of an elongated form. These packages may adjoin the aircraft fuselage structure in the direction of the longitudinal axis of the aircraft. They may be completely enclosed by a burn-through-proof foil which is arranged in a space enclosed by interior paneling and by the panels of the outer skin. The longitudinal end of the fuselage insulation package continues outward with a flat insulation end section is attached which is attached to a rib-attachment region arranged below the respective longitudinal sides of a rib and near the stringer by means of burn-through-proof attachment elements arranged on the inside of the aircraft with respect to the insulation.
