MULTIDENSITY LINER/INSULATOR

摘要

A liner/insulator (10) includes a pad of fibrous material (12) having a lofty, acoustically insulating portion (14) and a relatively higher density skin (16) along a first face thereof that may function as a water barrier. The acoustical liner is a non-laminate made from polyester, polyethylene, polypropylene, polyethylene terephthalate, glass fibers, natural fibers and any mixtures thereof. For certain applications the liner/insulator may incorporate a facing on one or even two opposing faces thereof. A method of insulating a door (38) including an exterior body panel (40) and an interior fascia panel (44) as well as a door for a vehicle are also disclosed and claimed.
