A faced fibrous insulation (10) having a facing (12) on one or more surfaces of a fibrous insulation material is provided. The facing provides improved surface quality, high and controlled adhesion, and is easily manufactured. The facing of the present invention includes a pre-applied adhesive (22, 24) that is heat activated to provide adhesion to the fibrous insulation. The facing may be input into the glass fiber forming section of a fibrous insulation production line. Alternatively, the facing may be applied to the uncured pack (64) prior to curing or applied to the cured fibrous insulation. As another alternative, a vapor barrier layer (14) may be attached on a surface of the insulation opposite the facing.
L~invention se rapporte à un isolant fibreux à parement (10) ayant un parement (12) sur une ou plusieurs surfaces d~un matériau d~isolation fibreux. Le parement fournit une qualité de surface améliorée, une adhérence contrôlée et élevée et il est facile à fabriquer. Le parement de la présente invention inclut un adhésif pré-appliqué (22, 24), qui est activé thermiquement pour fournir un caractère adhérent à l~isolant fibreux. Le parement peut être injecté dans la section de formation de fibres de verre d~une chaîne de fabrication d~isolant fibreux. En variante, le parement peut être appliqué sur l~ensemble non durci (64) ou sur l~isolant fibreux durci. En autre variante, une couche barrière vis-à-vis de la vapeur d~eau (14) peut être fixée sur la surface de l~isolant, opposée au parement.
