Abstract
The present disclosure relates to a hollow board 1 with first and second main surface layers 3, 5. A plurality of distance elements connecting the first and second main surface layers and maintain a predetermined distance there between. The main surface layers include at least a layer of high-density fiber, HDF, board, and a plurality of distance elements are distributed in the space between the main surface layers, and at least some comprise at least one elongate HDF board strip 15 which is oriented such that its longitudinal edges interconnect the first and second main surface layers 3, 5. The HDF boards of the surface layers and of the at least some of the distance elements comprise wood particles bonded by a resin including an isocyanate, such as methylene diphenyl di-isocyanate, MDI.

Hollow board comprising first and second main surface layers and a plurality of distance elements connecting the first and second main surface layers and maintaining a predetermined distance there between, wherein:
- (i) each main surface layer including at least a layer of board having a density of at least 800 kg/m3;
- and
- (ii) a plurality of distance elements distributed in a space between the main surface layers, wherein the first and second main surface layers and at least one side edge surface of the hollow board are made from a single piece of board having a density of at least 800 kg/m3.
