COMBINED THERMAL AND ACOUSTIC INSULATOR

摘要

A combined thermal and acoustic insulator (10) comprises a first metallic material layer (20) formed, for example, from a metal foil, a fibrous low density material batt layer (30) adjacent the first metallic layer, a high density plastic material layer (40), and a second metallic foil layer (50). The first metallic material layer forms the heat exposed side (12) and the second metallic layer forms the shielded side of the insulator (14).
