Abstract
A building panel having a thickness after pressing, the building panel 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% or less, the thickness distribution defined by the formula: ((Dmax−Dmin)/(Dmax+Dmin))×100 and a method for producing a building panel.
Claims21
A building panel, which was formed by pressing, the panel comprising:
- a substrate,
