Component (10) for
exhaust gas aftertreatment, with a housing (26) that defines an inner cavity (56) through which exhaust gases can pass, the housing (26) consisting of an inner body (34), an outer body (32) and a space (66) defined between the inner body (34) and the outer body (32), and an insulation
package (100) positioned in the room (66), wherein the insulating
package (100) consists of insulating material (102) encapsulated in a flexible fabric (104) and an at least partially rigid element (110) whose stiffness is greater than the stiffness of the insulating material (102) and the flexible fabric (104), characterized by that the at least partially rigid element (110) extends over a significant part of the width (W) of the insulation
package (100) and thereby substantially prevents bending, curvature or compression of the insulation package (100) in the width direction, so that the insulation package (100) is generally flexible along its length (L) but substantially rigid along its width (W), and that the at least partially rigid element (110) is attached to an outer surface of the flexible fabric (104).
