Abstract

The present invention relates to a method of manufacturing a heat shield and to a heat shield manufactured with this method. Heat shields of this type are particularly used in the field of the automobile industry. According to the method according to the invention, an insulating material, performed in a suitable contour and consisting of graphite, for example vermiculite, without binding agent, is inserted as an insulating plate (4) between two flat materials (2, 3), consisting of sheet metal, for example. The flat materials (2, 3) are then connected to one another at their edges in a positive or non-positive manner. The insulating material is here compressed, before or after being deposited on the flat material, to form a coherent insulating plate.
