Claim:
A floorboard for making a wood flooring, the floorboard having a core comprising wood lamellae and a surface layer arranged on an upper side of the core, the floorboard having a longitudinal direction and short direction orthogonal to the longitudinal direction, wherein the core comprises at least two layers of material, which are arranged at different distances from the surface layer, and which differ in respect of material properties or material composition, and wherein a first core layer closest to the surface layer comprises HDF or MDF, and is uniformly dimensioned, and a second core layer comprised of a wood fiber based material is positioned farther from the surface layer than the first core layer, wherein the second core layer comprises slats, the slats are perpendicular to the longitudinal direction of the floorboard, the slats having a fiber orientation which is perpendicular to the longitudinal direction of the floorboard and perpendicular to the fiber orientation of the surface layer, and the second core layer is directly attached to the HDF or MDF of the first core layer, wherein said surface layer is a continuous sheet of a wood veneer, which is arranged directly on said HDF or MDF layer.
