A multilayer mounting mat for an exhaust gas treatment device comprising high temperature resistant inorganic fibers, optionally an organic binder, and optionally an expandable material. The plurality of mounting mat plies contain most of the inorganic fibers oriented in the xy plane of the mounting mat. An exhaust gas treatment device housing, a fragile catalyst support structure elastically mounted in the housing, and a multilayer mounting mat provided in a gap between the housing and the fragile catalyst support structure.
