Building panel and a method to produce such a building panel

A method to manufacture a building panel comprising:

• joining a first material and a second material to form a first layer and a second layer of a semi-finished panel, wherein said first material comprises at least one or more of a thermoplastic material, a thermoset material, a mineral based material and/or a combination thereof,
• applying a third layer on the second layer, and
• applying heat and pressure to form said building panel,
• wherein the first layer forms a core of the building panel and the third layer forms a surface layer of the building panel, and
• wherein the second layer forms a sublayer between the first layer and the third layer of the building panel,
• wherein the second layer is configured to be at least partly plastically deformed when heat and pressure is applied, wherein the second layer is plastically deformable, such that the shape of the second layer is changeable under the application of heat and pressure and the changed shape is maintained during and after the application of heat and pressure, and such that a depression of at least 0.04 mm is formed when an embossing plate with a rill of 1.2 mm depth and a base width of 2 mm is pressed against the second layer at a pressure of 20 bar and a temperature of 80° C. for 35 seconds,
• wherein the second layer is more plastically deformable than the first layer.
