A three-dimensional vacuum thermal insulation element having a compressed three-dimensional porous structure and a shell closed in an airtight manner. The shell includes a thermoformable barrier wall and encloses the porous structure arranged between two major surfaces of said barrier wall. The porous structure has a pressure of between less than 105 Pa and more than 10-2 Pa at ambient external temperature and pressure. The barrier wall is thermoformed at the site of said two major surfaces, between which the porous structure has a curved shape and/or reliefs and/or depressions.

3D thermoformed element

The invention relates to a process for preparing a gelled, dried composition forming a monolithic aerogel with a heat conductivity of less than or equal to 40 mW&#xb7;m&#xb7;Kand derived from a resin of polyhydroxybenzene(s) and formaldehyde(s), to this aerogel composition and to the use thereof. This process comprises: According to the invention, step a) is performed in the presence of a cationic polyelectrolyte dissolved in this solvent, and the process also comprises a step d) of heat treatment under inert gas of the dried gel obtained in step c) at temperatures of between 150&#xb0; C. and 500&#xb0; C. to obtain the non-pyrolyzed aerogel whose heat conductivity is substantially unchanged, even after exposure to a humid atmosphere.

Monolithic, super heat-insulating, organic aerogel composition preparation method, said composition, and the use thereof

An assembly comprising at least one first pocket () which contains a thermally insulating material () and in which a first controlled atmosphere prevails, and at least one second pocket () which surrounds the first pocket and in which a second controlled atmosphere prevails. The first controlled atmosphere is different from the second one and corresponds to a vacuum of 10 Pa or less. The thermally insulating material () preferably has open cells with a diameter greater than or equal to 1 micron.
