A heat shield for an exhaust system of a vehicle includes a resinified spaced layer fabric having at least one inner layer, at least one outer layer, and at least one spacer between the inner layer or layers and the outer layer or layers to form one or more insulative spaces. The heat shield includes an emissivity reducing material. The insulative space is between about one and about eight millimeters thick, to reduce convective heat transfer.


[ I claim:] [1.] A shielding system for components of a vehicle exhaust system, the system comprising a first layer and a second layer, and a space between the first and second layers, the spacer holding the second layer a distance of about one to about eight millimeters from the first layer to form an insulative space between the first layer and the second layer, the insulative space being substantially filled with a gas, and means for holding the system to a component of the exhaust system.
