An insulation assembly includes an elongated batt of fibrous insulation material (52) having two opposed major surfaces (54, 56), where the batt (52) has a first facing (60) secured on its first major surface (54). The first facing (60) extends beyond the side edges of the batt (52) to form opposed flanges (32) suitable for attaching the insulation assembly (70) to a building structure. The batt (52) has a second facing (62) secured on its second major surface (56), with the second facing (62) extending beyond the side edges of the batt (52) to form opposed flanges (32) suitable for attaching the insulation assembly (70) to a building structure. The method of making an insulation assembly (70) includes moving a batt of fibrous insulation material (52) along a path, where the fibrous insulation material (52) has two opposed major surfaces (54, 56). A continuous encapsulation material (16) is applied to the pack (10), and a portion of the encapsulation material (16) is continuously gathered to form a two part fold (22). The two parts of the fold (22) are bonded together to form a flange (32) suitable for attaching the insulation assembly (70) to a building structure.

Cette invention concerne un ensemble d'isolation composé d'un panneau semi-rigide allongé de matériau isolant fibreux (52) qui présente deux surfaces principales (54, 56) opposées. Le panneau (52) comporte un premier revêtement (60) fixé sur sa première surface principale (54). Ce premier revêtement (60), qui dépasse des bords latéraux du panneau (52), forme des rebords opposés (32) destinés à fixer l'ensemble d'isolation (70) sur une structure de la charpente. De même, le panneau (52) comporte un second revêtement (62) fixé sur sa seconde surface principale (56). Ce second revêtement (62), qui dépasse des bords latéraux du panneau (52), forme des rebords opposés (32) destinés à fixer l'ensemble d'isolation (70) sur une structure de la charpente. Pour la fabrication de l'ensemble d'isolation (70), on déplace le long d'un trajet un panneau semi-rigide de matériau isolant fibreux (52) qui présente deux surfaces principales opposées (54, 56). Une matière d'encapsulage (16) est appliquée en continu tout autour de l'enveloppe (10), une partie de la matière d'encapsulage (16) étant pincée tout du long pour former un double pli (22). Collées l'une à l'autre, les deux parties du pli (22) forment un rebord (32) qui sert à fixer l'ensemble d'isolation (70) sur une structure de charpente.
