The “nobel” quality designates the manufacturing of solid wood lamella panels glued width-wise. This is also referred to by the name “ lumber-cored ”. This results in panels with a more homogeneous appearance, closer to "traditional" manufacturing. The length of these panels generally does not exceed 2.5 m due to the raw material required.
The "glued-laminated" or “finger-jointed” quality refers to panels manufactured using to a more recent manufacturing process. The solid wood lamellas are glued together width-wise and length-wise. This also makes it possible to produce panels of larger dimensions.
In both cases, the wood grain of the panel is length-wise.
