Abstract

The invention relates to a wall (11) comprising a thermally insulating barrier (12, 14) and a metallic sealing membrane (13, 15) resting against the thermally insulating barrier; the thermally insulating barrier comprising at least one load-bearing element (20), the load-bearing element comprising: - a hollow pillar (21) made of composite material rising along the thickness direction (E) of the wall, - a sleeve (25) made of composite material fitted onto the hollow pillar and bonded to a longitudinal surface of the pillar; and - an internal plate (22) made of metal, fixed to the sleeve via a fastening device and against which the sealing membrane is welded, wherein the sleeve has an internal end that is flush with an internal end of the pillar and wherein the internal plate bears, directly or indirectly, partly against the internal end of the pillar and partly against the internal end of the sleeve.
