Abstract
A shield for mounting on a vehicle intermediate the passenger compartment and the exhaust system is formed as a sandwich of a fibrous layer between two heat reflecting layers. During the manufacturing process a hardenable resin impregnates the periphery of the fibrous layer and hardens in place to serve as an adhesive for bonding the layers together and providing a hard rigid mounting bracket. The fibrous layer intermediate its peripheral edges is relatively loosely held in place to serve as a sound absorbing barrier.
