The invention relates to an insulating arrangement for the inner insulation of an aircraft according to the preamble of claim 1. Appropriate measures (and control of ventilation) ensure that almost no humid air or other humid gas or water (vapor) particles penetrate a film-covered insulating packet (1) while the accumulated humidity will quickly and easily escape (if such accumulation has taken place) from the insulating packet (1). The insulating arrangement consists of an insulating packet (1) which is covered by a film (4). The film is arranged within a clearance (7) between an inner insulation (12) and a shell (6). The insulating packet (1) which is completely covered by the film (4) does not line the clearance (7) entirely. The film consists of a gas- permeable film material which permits realization of different diffusion resistance behaviors depending on the direction of diffusion of the entire structure.

L'invention concerne une structure isolante pour l'isolation intérieure d'un aéronef, selon le préambule de la revendication 1. Des mesures appropriées (et des ventilations adéquates) permettent d'éviter que de l'air humide ou toute autre particule humide de gaz ou (de vapeur) d'eau ne pénètre dans un paquet isolant (1), et qu'à l'inverse, (dans le cadre d'une accumulation ainsi effectuée) l'humidité accumulée puisse se dégager rapidement et facilement du paquet isolant (1). La structure isolante comprend un paquet isolant (1) entouré d'un film (4) situé dans un espace intermédiaire (7) entouré d'un habillage intérieur (12) et d'une enveloppe extérieure (6). Le paquet isolant (1) qui est entièrement entouré par le film (4) ne garnit pas totalement l'espace intermédiaire (7). Le film se compose d'un matériau pelliculaire traversé par des gaz, qui permet de transformer un comportement de résistance à la diffusion différencié, en fonction du sens de diffusion de la structure globale.
