An acoustic and thermal shield for a motor vehicle, including a porous shell based on fibers bound together by a binding agent and a spring layer based on elastically compressible polyurethane foam, the porosity of the shell being such that the foam is able to create a sealed skin on the underside of the shell, which fibers consist of two types: thick reinforcing fibers in an amount of 25 to 40% by weight of the shell and fine fibers in an amount of 15 to 35% by weight of the shell, the bonding agent being formed by fusible bonding fibers in an amount of 35 to 50% by weight of the shell, so that substantially no foam penetrates the thickness of the shell.
