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 an electrically conducting adhesive tape out of aluminum, the entire shielding surface being connected to ground therein. |
