A device suitable for use as a catalytic converter for the purification of exhaust gases from an internal combustion engine includes a ceramic monolith catalyst element resiliently mounted within a metallic housing. The metallic housing is in turn mounted within a hot gas chamber, such as an expansion chamber or muffler of a motorized vehicle. The ceramic monolith is wrapped with an insulating layer of inorganic ceramic fiber. At least one layer of intumescent material is disposed between the metallic housing and the inorganic fiber layer.
