Beschreibung
Zusammenfassung:	An article comprises a tube having peripheral areas, including an upper section, a lower section, an inner section, and an outer section, the tube further comprising a tube wall having an inner layer and an outer layer, the inner layer being a semipermeable membrane that is permeable to vapors but impermeable to liquids and the outer layer being a nonwoven fabric, and the tube further comprising at least one inlet port integrated into the tube wall to permit the flow of an activated or activatable foamable composition into the tube interior, wherein the tube further has a plurality of holes that penetrate through the inner and outer layers of the tube to allow expanding foam to both fill the interior of the tube and exit the tube and fill a space exterior to the tube. L'invention concerne un article comprenant un tube ayant des zones périphériques, comprenant une section supérieure, une section inférieure, une section interne et une section externe, le tube comprenant en outre une paroi de tube ayant une couche interne et une couche externe, la couche interne étant une membrane semi-perméable qui est perméable aux vapeurs mais imperméable aux liquides et la couche externe étant un non-tissé, et le tube comprenant en outre au moins un orifice d'entrée intégré dans la paroi de tube pour permettre l'écoulement d'une composition expansible activée ou activable dans l'intérieur du tube, le tube ayant en outre une pluralité de trous qui pénètrent à travers les couches interne et externe du tube pour permettre l'expansion de la mousse à la fois pour remplir l'intérieur du tube et sortir du tube et remplir un espace extérieur au tube.
