A thin-walled structure (e.g., an end cone insulator () and/or a mounting mat) () comprising insulating material suitable for insulating portions (e.g., an end cone) of a pollution control device () and/or mounting material suitable for mounting a pollution control element in a pollution control device () (e.g., a catalytic element in a catalytic converter, a filter element in a diesel or gasoline engine exhaust filter, etc.). The thin-walled structure can comprise an insulating material and/or mounting material in the form, for example, of a sheet, mat () or three-dimensional thin walled structure (e.g., a single piece or multiple piece three dimensional end cone insulator). () An intermediate adhesive () (e.g., a heat activated adhesive, hot melt adhesive and/or adhesive-like thermoplastic material) is bonded to at least one major surface of the thin-walled structure so as to coat and penetrate into the at least one major surface. The intermediate adhesive () at least mechanically bonds to the thin-walled structure. A pressure sensitive () adhesive is bonded to the intermediate adhesive () and used to secure the thin-walled structure in place in the pollution control device ().
