Abstract

Cette invention concerne un ensemble garniture/isolant (10) comprenant un coussin de matière fibreuse (12) qui comprend une partie spongieuse, isolante au plan acoustique (14) dont une première face est recouverte une couche de densité relativement plus élevée (16) pouvant agir comme paroi étanche à l'eau. La garniture acoustique, non laminée, est faite de polyester, polyéthylène, polypropylène, polyéthylène téréphthalate, fibres de verre, fibres naturelles, seuls ou mélangés. Pour certaines applications, l'ensemble garniture/isolant peut comporter un parement sur une de ses faces, voire sur deux faces opposée. Est également décrite un procédé d'isolation de porte (38) comprenant un panneau de carrosserie extérieur (40) et un panneau intérieur de capitonnage (44). L'invention concerne également une portière de véhicule.
