Abstract

L'invention concerne un module de canal en une mousse de particules de plastique, en particulier pour des systèmes de répartition d'air ou de ventilation, qui comporte plusieurs éléments de canal qui sont raccordés les uns aux autres de manière étanche à l'air et qui constituent une couche d'isolation qui entoure au moins partiellement un espace creux. À l'aide d'éléments d'armature moulés par injection qui peuvent être raccordés aux éléments de canal entourant un espace creux par leur extrémité ouverte, le module de canal est stabilisé. Les éléments d'armature sont assemblés à partir de quelques pièces individuelles et sont de plus équipés de géométries de raccordement qui permettent de raccorder ensemble des modules de canal de manière étanche à l'air pour produire un système de canal adaptable de manière flexible. L'invention concerne en outre un procédé de production d'un système de canal étanche à l'air par assemblage de modules de canal selon l'invention à partir d'éléments de canal et d'éléments d'armature.
