1. A large-format building board having a large edge length of the desired height between floors, which board contains fibrous organic additives and hydraulic binders in such a form that the building board has, in cross-section, a less dense, thick core zone (2 and 3) with coarse fibres and at least one thin denser outer surface (1) of fine materials, characterized in that the core region comprises layers (2, 3) or different thickness, poured green-on-green onto one another, and become denser, and have increasing strength, going outward from the centre of the cross-section of the building board, and that the dense outer surface is a thin layer (1), which has also been cast green-on-green and has a smooth surface (01), which layer also extends over the narrow sides of the building board to form dense sealed edges.
