Zusammenfassung:	An embodiment method can form an oriented strand board panel. A lay-up has a first surface layer, a second surface layer and a core between the first surface layer and the second surface layer. The first surface layer comprises wood strands with a binding resin that comprises phenolic resin without comprising a pMDI resin and the second surface layer is comprising wood strands with a binding resin that comprises pMDI resin without comprising any phenolic resin. The lay-up is located in a press that includes a first platen facing the first surface layer and a second platen facing the second surface layer. The first surface layer contacts the first platen and the second surface layer contacts a screen. The lay-up is pressed and consolidated to form a consolidated panel having a smooth outer surface of the first surface layer and a rough outer surface of the second surface layer.
