Abstract
An acoustical and thermal insulator in the form of a multilayer composite includes a first facing layer such as a heat reflective material layer, a polymer based blanket layer and an insulation insert encapsulated in the polymer based blanket layer. The insulator may also include a second facing layer. The insulation insert is sized and positioned in the insulator so as to provide extra thermal insulation at selected hot spots and/or extra acoustical insulation at high noise points of a vehicle to which the insulator may be mounted.
