A sleeve (10) for providing thermal insulation to elongated substrates (30) is disclosed. The sleeve (10) is formed from a composite sheet (10) having a tough, resilient reinforcing layer (14) to which are attached a metallic reflective layer (16) on one side and a fibrous, non-woven insulative layer (12) on the opposite side. The composite sheet (10) is reverse folded (20) with the reflective layer (16) facing outwardly and the insulative layer (12) facing inwardly. A seam (26) is formed lengthwise along the sleeve (18) in spaced relation to the reverse fold (20), thereby defining a central space (28) for receiving the elongated substrates (30). The seam (26) is formed by fusing the inwardly facing insulative layer (12) on each side of the reverse fold (20) together.
Manchon (10) assurant une isolation thermique à des substrats allongés (30) et constitué d'une feuille composite (10) comprenant une couche de renforcement résiliente, robuste (14) à laquelle est attachée une couche réfléchissante métallique (16) sur un côté et une couche isolante, non tissée, fibreuse (12) sur le côté opposé. La feuille composite (10) est repliée à l'envers (20), la couche réfléchissante (16) donnant sur l'extérieur et la couche isolante (12) sur l'intérieur. Une couture (26) est formée le long du manchon (18) espacée du pli retourné (20), ce qui forme un espace central (28) pour recevoir le substrats allongés (30). La couture (26) est obtenue par fusion de la couche isolante donnant sur l'intérieur (12) de chaque côté du pli retourné (20).
