Method of producing a building panel and a building panel
First Claim
1. A method of producing a building panel, comprising:
- providing a core,applying a balancing layer on a first surface of the core, wherein the balancing layer has a first moisture content and comprises a sheet impregnated with a thermosetting binder,applying a surface layer on a second surface of the core, wherein the surface layer has a second moisture content and comprises a thermosetting binder,adjusting the first moisture content of the balancing layer such that the first moisture content of the balancing layer is higher than the second moisture content of the surface layer prior to curing by applying heat and pressure, andcuring the surface layer and the balancing layer by applying heat and pressure.
