A process for preparing a fiberglass insulation product, including the steps of: (a) providing a layer of fire-retardant kraft paper, (b) coating the fire- retardant kraft paper layer with from 2 to 10 pounds (0.91 to 4.54 kg) of HDPE or of polypropylene per 3000 square feet (278.7 square meter) of the paper to form an HDPE-fire-retardant kraft laminate or a polypropylene-fire-retardant kraft laminate, (c) coating the HDPE-fire-retardant kraft or polypropylene- fire-retardant kraft laminate with from 3 to 10 pounds (1.36 to 4.54 kg) of LDPE per 3000 square feet (278.7 square meter) of the HDPE-fire-retardant kraft laminate or polypropylene-fire-retardant kraft laminate to form an LDPE- HDPE-fire-retardant kraft laminate or an LDPE-polypropylene-fire-retardant kraft laminate, (d) adjusting the temperature of the LDPE-HDPE-fire-retardant kraft laminate or the LDPE-polypropylene-fire-retardant kraft laminate so that the LDPE becomes tacky while the HDPE or polypropylene remains solid, (e) providing a layer of fiberglass wool, and (f) contacting the LDPE layer of the LDPE-HDPE-fire-retardant kraft laminate or of the LDPE-polypropylene-fire- retardant kraft laminate with the fiberglass wool layer with pressure and cooling to bond the LDPE-HDPE-fire-retardant kraft laminate or LDPE- polypropylene-fire-retardant kraft laminate to the fiberglass wool layer to form a fiberglass insulation product.
L'invention porte sur un procédé de préparation de produits isolants à base de fibres de verre comportant les étapes suivantes: (a) acquisition d'une couche de papier kraft ignifugé; (b) enduction du papier kraft d'une couche de HDPE ou de polypropylène, à raison de 2 à 10 livres (0,91 à 4,54 kg) par 3000 pieds carrés (278,7 m?2¿) de papier de manière à former un laminé ignifugé; (c) enduction du papier kraft ainsi traité d'une couche de LDPE ou de propylène, à raison de 3 à 10 livres (1,36 à 4,54 kg) par 3000 pieds carrés (278,7 m?2¿) de papier de manière à former un laminé doublement ignifugé; (d) réglage de la température à laquelle on porte le laminé pour que le LPDE devienne poisseux et que l'HDPE ou le polypropylène reste solide; (e) acquisition d'une couche de laine de fibres de verre; (f) mise en contact sous pression de la couche poisseuse de LDPE avec la couche de laine de fibres de verre; et (g) refroidissement de l'ensemble pour former un produit isolant à base de fibres de verre.
