Abstract
A combined thermal and acoustic insulator comprises a first metallic material layer formed, for example, from a metal foil, a fibrous low density material batt layer adjacent the first metallic layer, a high density plastic material layer, for example, a mass loaded elastomer, adjacent the batt material layer, and a second metallic foil layer. The first metallic material layer forms the heat exposed side and the second metallic layer forms the shielded side of the insulator. Alternatively, additional layers may be provided, for example, a third foil layer adjacent the fibrous material layer and a second fibrous layer between the third metal foil layer and the first metal foil layer.
