Title
(EN) IMPROVED THERMAL AND ACOUSTICAL INSULATING SHIELD
(FR) ECRAN D'ISOLATION THERMIQUE ET ACOUSTIQUE AMELIORE
Abstract
(EN) A flexible, adhesively attachable, self-sealing, thermals and acoustical insulating shield has a needle, flexible, fibrous bat (40) having an insulating layer (43) of insulating fibers (44) disposed between opposite binding layers (41, 42) of binding fibers (45). Binding fibers (45) of each binding layer (41, 42) are needledly disposed trough the insulating layer (43) and an opposite binding layer (41, 42) to provide tufts (46) of binding fibers (45) protruding from the opposite binding layer (41, 42) so as to form a tufted upper surface (47) and a tufted lower surface (48) of the bat (40).
(FR) La présente invention concerne un écran d'isolation thermique et acoustique autocollant, adhésif et souple qui possède une aiguille, une dalle (40) de fibre souple comprenant une couche d'isolation (43) constituée de fibres isolantes (44), placée entre des couches de liaison (41, 42) opposées constituées de fibres de liaison (45). Les fibres de liaison (45) de chaque couche de liaison (41, 42) sont nécessairement positionnées à travers la couche d'isolation (43) et une couche de liaison opposée (41, 42) de façon à permettre à des touffes (46) de fibres de liaison (45) de se projeter à partir de la couche de liaison (41, 42) opposée et former ainsi des surfaces supérieure (47) et inférieure (48) de la dalle (40) tuftées.
