    Abstract: An assembly comprising at least one first pocket (3) which contains a thermally insulating material (5) and in which a first controlled atmosphere prevails, and at least one second pocket (7) 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 (5) preferably has open cells with a diameter greater than or equal to 1 micron.

    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 translation: 根据本发明,步骤a)在溶解在该溶剂中的阳离子聚电解质的存在下进行,并且该方法还包括步骤d)在步骤c)中获得的干燥凝胶的惰性气体下,在 150℃和500℃,以获得即使在暴露于潮湿气氛之后其导热性基本上不变的非热解气凝胶。
