Abstract
A building panel having a thickness (D) after pressing and including a substrate, a first sub-layer including a binder arranged on a first side of the substrate and a surface layer including a first wood veneer, arranged on the first sub-layer, wherein the building panel has a thickness distribution of about ±7.5%, the thickness distribution defined by the formula: ((Dmax−Dmin)/(Dmax+Dmin))×100 and a method for producing a building panel.
Claims21
A method to produce a building panel, the method comprising:
- providing a substrate,
- scattering a powder comprising a binder on a first side of the substrate, to obtain a first sub-layer;
- applying a first wood veneer on the first sub-layer to obtain a surface layer,
- applying heat and pressing by external pressure to bond the surface layer, the first sub-layer and the substrate to obtain a building panel such that the building panel has a thickness D after the pressing, wherein the thickness D has a thickness distribution Ddistr Of about ±7.5% or less, the thickness distribution Ddistr being defined by the formula:
