Abstract

L'invention concerne un procédé pour produire une isolation dans une cavité entre une cloison d'un bâtiment et l'enveloppe extérieure. Des éléments d'isolation provenant d'unités d'emballage sont placés dans ladite cavité et ces derniers sont disposés sous forme d'au moins deux couches adjacentes, l'une derrière l'autre, situées entre l'enveloppe extérieure et la cloison du bâtiment. L'objectif de l'invention est de créer un procédé de ce type, de sorte qu'une isolation peut être formée rapidement dans une cavité située entre la cloison du bâtiment et l'enveloppe extérieure, sans que les problèmes susmentionnés, tels que les endroits présentant des discontinuités, n'apparaissent, et que l'isolation peut être réalisée dans une pluralité de cas grâce à l'obtention de caractéristiques d'isolation améliorées. A cet effet, les couches adjacentes de l'isolation sont formées par des éléments d'isolation différents en ce qui concerne leur construction et/ou leurs propriétés mécaniques, leurs matériaux, leur masse volumique apparente, leur résistance à la flexion et/ou leur rigidité.
