  • an insulation barrier with insulating blocks that are as standardized as possible in order to reduce manufacturing costs.
  • the construction of a large load-bearing structure such as the hull of a ship is subject to high dimensional tolerances, for example several centimeters, which prevent the dimensions of a vessel from being fully planned before its construction. It follows that it may be necessary to construct at least some of the insulating blocks to measure according to the actual dimensions of the load-bearing structure.
  • One idea at the basis of the invention is to propose a sealed and thermally insulating tank with a multilayer structure which makes it easier to take into account at least some of the aforementioned constraints.
  • Another idea underlying the invention is to provide a waterproof and insulating multilayer structure which is easy to produce over large surfaces.
