One or more of the core, the upper arrangement and the lower arrangement includes a mineral-based layer, preferably including magnesium oxide. One or more of the mineral-based layers includes reinforcement fibres embedded in a mineral-based matrix, preferably including magnesium oxide. The fibres are configured to increase the tensile strength of the mineral-based layer.
