  • a flexible outer skin formed from a plurality of metal cups having open ends which face inward toward an interior of the aircraft, and closed base ends which are smaller than the open ends and which face outward and away from the interior of the aircraft, sidewalls which are joined with the sidewalls of adjacent metal cups with the base ends spaced apart with thermal expansion gaps extending therebetween;

    rigid insulation formed from a plurality of ceramic blocks which are spaced apart and have outer ends which extend into the open ends of the metal cups, wherein the flexible outer skin extends over the ceramic blocks and retains the ceramic blocks against the interior of the aircraft; and

    an inner barrier extending across the inner ends of the blocks to block moisture transfer.
