Abstract
The invention relates to a soundproof thermal shield (), particularly for motor vehicles, comprising an aluminum support (), a noise-absorbing layer () and an aluminum thermal covering (). In order to make the inventive soundproof thermal shield easy to recycle while obtaining a great thermal shielding effect and noise-absorbing power, a permeable mat made of knitted aluminum is used as a noise-absorbing layer (), said knitted aluminum being superimposed in several layers and pressed so as to form the permeable mat. The inventive thermal shield is thus made of a single material. Preferably, the support () is made of a microperforated aluminum sheet while the thermal covering () is preferably made from an aluminum film.
