The fire-resistance of such a partition wall is increased in that its frame structure (15, 16) which extends between the floor and ceiling of a room is covered with mineral fibre boards (19, 21) which can be faced on the room side with gypsum boards (20, 22). The mineral fibre boards (19, 21) are suitably composed of approximately 75% of mineral wool, approximately 15% of fillers consisting of clay and approximately 10% of organic binders consisting of starch products. <IMAGE> |
