An insulation plate 1 out of mineral wool, for protection against detrimental environmental influence due to electromagnetic fields has an electrically conducting layer 2 on its surface, which preferably consists of a perforated aluminum film. For connection to form a wall lining, the layer 2 at its margin overlaps with adjacent insulation plates or the electrical connection with one another is effected with the aid of a electrically conducting adhesive tape out of aluminum, the entire shielding surface being connected to ground therein. |
