<p>The device (1) has an outer wall (4), and an inner wall (3) arranged opposite to a component (2) that emits heat and noise, where component is formed by a precatalytic exhaust pipe of an exhaust line. An intermediate layer (5) presenting acoustic absorption and thermal insulation properties is arranged between the walls (3, 4). The walls and the intermediate layer are associated with each other by seaming using a wire. An independent claim is also included for a thermally protected assembly comprising a component that emits heat and noise, and a thermal and sound protective device.</p> |
