  • Patent number: 5743058
    Abstract: The invention relates to a wall board suitable for fixing to two profiles (1) extending vertically along the edges of the wall board (5), wherein the wall board is adapted for gripping by the profiles in form-fitting manner. As a result of this step no use need be made of fixing means which grip directly onto the wall board itself, so that damage of the wall board itself is avoided, and the boards with the profiles are completely re-usable. It is even possible to arrange finishes on the boards before assembly. According to a preferred embodiment the gripping means are formed on at least a first edge of the wall board (5) by noses (12) arranged on the profile, wherein a groove for the profile extends partially between the nose and the wall board.
