An insulation product (60) includes an elongated batt (62) of fibrous insulation material, and a facing adhered to a major surface of the batt (62), wherein the facing (64) is a coextruded polymer film of barrier (70) and bonding layers (72), with the bonding layer (72) having a softening point lower than the softening point of the barrier layer (70), with the bonding layer (72) being one or more materials of the group consisting of ethylene N-butyl acrylate, ethylene methyl acrylate and ethylene ethyl acrylate, and wherein the facing (64) has been heated to a temperature above the softening point of the bonding layer (72), but below the softening point of the barrier layer (70), whereby the facing (64) is adhered to the batt (62) by the attachment of the bonding layer (72) to the fibers in the batt (62) due to the softening of the bonding layer (72).
Un produit d'isolation (60) comprend un matelas allongé (62) de matériau isolant fibreux, et un revêtement collé sur une surface principale du matelas (62), le revêtement (64) est un film polymère coextrudé d'une couche d'arrêt (70) et d'une couche de liaison (72), la couche de liaison (72) a un point de ramollissement inférieur au point de ramollissement de la couche d'arrêt (70), la couche de liaison (72) comprenant un ou plusieurs matériaux du groupe contenant de l'éthylène N-butylacrylate, de l'éthylène méthylacrylate et de l'éthylène éthylacrylate. Le revêtement (64) a été chauffé à une température supérieure à celle du point de ramollissement de la couche de liaison (72), mais inférieure à celle du point de ramollissement de la couche d'arrêt (70), de manière que le revêtement (64) soit collé au matelas (62) par la fixation de la couche de liaison (72) aux fibres du matelas (62) du fait du ramollissement de la couche de liaison (72).
