    Abstract: 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·m−1·K−1 and derived from a resin of polyhydroxybenzene(s) and formaldehyde(s), to this aerogel composition and to the use thereof. This process comprises: a) polymerization in an aqueous solvent of said polyhydroxybenzene(s) and formaldehyde(s) in the presence of an acidic or basic catalyst, to obtain a solution based on the resin, b) gelation of the solution obtained in a) to obtain a gel of the resin, and c) drying of the gel to obtain a dried gel. 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° C. and 500° C. to obtain the non-pyrolyzed aerogel whose heat conductivity is substantially unchanged, even after exposure to a humid atmosphere.

    Abstract: 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.

    Abstract: A three-dimensional, vacuum thermal insulating element comprising a compressed three-dimensional porous structure, an envelope closed in an airtight manner comprising a thermoformable barrier wall, enclosing the porous structure, which is interposed between two major surfaces of the barrier wall, and where, at outside ambient temperature and pressure, a pressure between less than 105 Pa and more than 10−2 Pa prevails. The barrier wall is thermoformed at said the two major surfaces, between which the porous structure is bent-shaped and/or has reliefs and/or depressions.
