A multilayer mounting mat for an exhaust gas treatment device including high temperature resistant inorganic fibers, optionally organic binder, and optionally intumescent material. A plurality of the mounting mat plies contain a substantial proportion of the inorganic fibers oriented in the x-y plane of the mounting mat. An exhaust gas treatment device includes a housing, a fragile catalyst support structure resiliently mounted within the housing, and the multilayer mounting mat disposed in a gap between the housing and the fragile catalyst support structure.
