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.

1. An acoustic and thermal insulator for a vehicle, comprising: a hood, dash, firewall or engine cover liner including a nonlaminate, non-needled multidensity acoustical and thermal insulating layer of polymer fiber selected from a group consisting of polyester, polypropylene, polyethylene, rayon, nylon and any mixtures thereof, and also including a nonlaminate skin of polymer fiber along at least one face of said acoustical and thermal insulating layer, said nonlaminate skin having a higher density than a remaining portion of said insulating layer. 2. The insulator of claim 1, wherein said acoustical and thermal insulating layer is a nonwoven fabric. 3. The insulator of claim 1, wherein said acoustical and thermal insulating layer further includes additional fibers selected from a group consisting of glass fibers and natural fibers. 4. The insulator of claim 1, including a first facing layer over a first face of said acoustical and thermal insulating layer, said facing layer being constructed from a polymer material selected from a group consisting of polyester, rayon, polyethylene, polypropylene, ethylene vinyl acetate, polyvinyl chloride and mixtures thereof. 5. The insulator of claim 4, including a second facing layer over a second face of said acoustical and thermal insulating layer. 6. The insulator of claim 5, wherein said first and second facing layer has a weight of between about 0.50-3.00 ounces per square yard. 7. The insulator of claim 5, wherein said acoustical and thermal insulating layer, said first facing layer and said second facing layer are approximately the same color. 8. The insulator of claim 4, wherein said acoustical and thermal insulating layer is white and said first facing layer is black. 9. The insulator of claim 4, wherein said acoustical and thermal insulating layer and said first facing layer are approximately the same color. 10. The insulator of claim 1, wherein said acoustical and thermal insulating layer is gray or black in color. 11. The insulator of claim 1, wherein the acoustic and thermal insulating layer is polymer fiber selected from a group consisting of polyester, rayon, and any mixtures thereof. 12. A hood, dash, firewall or engine cover liner for a vehicle, comprising: A nonlaminate, non-needled multidensity acoustical and thermal insulating layer of substantially 100% polyethylene terephthalate nonwoven fabric having a relatively high density skin along at least one face thereof. 13. The liner of claim 12, including a first facing layer over a first face of said acoustical and thermal insulating layer, said first facing layer being constructed from a polymer material selected from a group consisting of polyester, rayon, polyethylene, polypropylene, ethylene vinyl acetate, polyvinyl chloride and mixtures thereof. 14. The liner of claim 13, wherein said acoustical and thermal insulating layer and said first layer are approximately the same color. 15. The liner of claim 13, including a second facing layer over a second face of said acoustical and thermal insulating layer. 16. The liner of claim 15, wherein said first and second facing layer has a weight of between about 0.50-3.00 ounces per square yard. 17. The liner of claim 15, wherein said acoustical and thermal insulating layer, said first facing layer and said second facing layer are all approximately the same color. 18. The liner of claim 12, wherein said acoustical and thermal insulating layer is gray or black in color. 19. An acoustical and insulating device for a vehicle, comprising: A hood, dash, firewall or engine cover liner including a nonlaminate, non-needled multidensity acoustical and thermal insulating layer of polymer fiber selected from a group consisting of polyester, polypropylene, polyethylene, rayon, nylon and any mixtures thereof that shows no signs of any thickness increase, delamination, deterioration or any undesirable effect which may affect performance for at least 330 hours at 150 degrees C., and also including a nonlaminate skin of polymer fiber along at least one face of said acoustical and thermal insulating layer, said nonlaminate skin having a higher density than a remaining portion of said insulating layer. 20. The insulator of claim 19, wherein said acoustical and thermal insulating layer is a nonwoven fabric. 21. A hood, dash, firewall or engine cover liner for a vehicle, comprising: A nonlaminate, non-needled multidensity acoustical and thermal insulating layer of polymer fiber selected from a group consisting of polyester, polypropylene, polyethylene, rayon, nylon and any mixtures thereof, and also including a nonlaminate skin of polymer fiber along at least one face of said acoustical and thermal insulating layer, said nonlaminate skin having a higher density than a remaining portion of said insulating layer; anda first facing layer over a first face of said acoustical and thermal insulating layer, said facing layer being constructed from a polymer material selected from a group consisting of polyester, rayon, polyethylene, polypropylene, ethylene vinyl acetate, polyvinyl chloride and mixtures thereof. 22. The liner of claim 21, including a second facing layer over a second face of said acoustical and thermal insulating layer.
