A fire-resistant, heat-reducing wall element (1) with at least 2 insulation layers (2, 2a) made of bound mineral wool contains a layer (3) arranged between the insulation layers (2, 2a), which consists of a mixture of a water-releasing hydroxide and an inorganic binder like water glass or silica sol is made. The layer (3) increases the fire resistance of the wall element (1), which is therefore particularly suitable as an insert for a fire-retardant door. |
