1. A structurally enhanced liner for selectively insulating against the transmission of sound and heat energy, comprising:
- a multi-layer substrate comprising an insulating layer and at least one structural layer, said structural layer comprising a reinforced composite, and said substrate being formed so as to have at least one lofted area for insulating against the transmission of sound and heat energy and at least one compacted area for structurally enhancing the liner.

Abstract
A liner for insulating against the transmission of sound and heat energy, such as from the engine compartment of a vehicle, is disclosed. The liner is formed of an insulating layer or core and first and second structural layers. By creating regions or areas of the liner that are selectively lofted or compressed, the attenuation of undesirable sound energy and absorption of heat energy can be balanced with the desired degree of structural enhancement to be afforded for a particular application.

10. A method of manufacturing a structurally enhanced liner for selectively insulating against the transmission of ambient sound and heat energy, comprising:
-
forming a multi-layer substrate comprising an insulating layer of material and first and second structural layers, each said structural layer comprising a reinforced composite;
compressing one or more selected regions of the substrate to structurally enhance the liner, while leaving at least one lofted region for insulating against the transmission of sound and heat energy. - View Dependent Claims (11, 12, 13, 14)
