Panel and method for producing a panel

A floor, wall, or ceiling panel, comprising:

• at least one core layer, the core layer comprising an upper core surface and a lower core surface and at least one pair of opposite side edges;
• wherein the at least one core layer has a density in a range of 1350 kg/m3 to 1550 kg/m3 and comprises a cement comprising magnesium oxide and having a crystal structure expressed as a ternary system of magnesium oxide, a magnesium salt, and water;
• wherein the at least one core layer further comprises at least 20 wt % natural fibers disperse in said cement;
• wherein the natural fibers comprise fibers encapsulated by the cement and form an interconnected matrix with the cement crystals in the core layer;
• wherein the natural fibers form a reinforcing network across the entire volume of the core layer;
• and
• wherein the density of the core layer is substantially constant over the entire volume of the core layer, wherein the spatial variation of density is below 10% over the entire volume of the core layer.
