Abstract: A hood, dash, firewall or engine cover liner is provided for a vehicle. The liner includes a nonlaminate acoustical and thermal insulating layer of polymer fiber that shows no signs of any thickness increase, delamination, deterioration or any undesirable effect which may affect performance for at least 330 hours when maintained at a temperature of at least approximately 150° C. The liner may include a relatively high density, nonlaminate skin of polymer fiber and/or one or more facing layers constructed from polymer material.

Abstract: An acoustical and thermal insulator provided which is suitable for use in a vehicle. The insulator includes a nonlaminate acoustical and thermal insulating layer of blend of polymer fibers and natural fibers. The fiber blend provides a lower cost material with similar acoustical, thermal properties. The insulator includes a relatively high density, nonlaminate layer of the fiber blend and/or one or more facing layers constructed from various materials.

Abstract: A trim panel insulator is provided for a vehicle. The insulator includes a nonlaminate acoustical and thermal insulating layer of polymer fiber. The insulator may include a relatively high density, nonlaminate skin of polymer fiber and/or one or more facing layers constructed from various materials.

Abstract: An acoustical liner with integral water barrier is provided. The liner includes a pad of fibrous material having a lofty, acoustically insulating portion and at least one heat-seared face of relatively higher density to provide water barrier protection. The acoustical liner is a non-laminate made from polyester, fiberglass, polypropylene and any mixtures thereof. A method of insulating a door including an exterior body panel and an interior fascia panel as well as a door for a vehicle are also disclosed and claimed.

Abstract: A liner/insulator includes a pad of fibrous material having a lofty, acoustically insulating portion and a relatively higher density skin 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 including an exterior body panel and an interior fascia panel as well as a door for a vehicle are also provided.

Abstract: An acoustical insulation product for a vehicle includes a blanket of fibers and a facing material adhered to a major surface of the blanket. The product has a perimeter flange made by pressing the facing material and an edge portion of the blanket together. The flange provides stiffness to the product, and the flange is capable of being held in place on the vehicle by an attachment system.
