Abstract
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.
