The forces of nature are shown in the Rohol Crack veneer surfaces. Cracks, that arise because of the shrinking and expanding of wood, are usually eliminated in the production of veneers or wood planks. Rohol makes use of the cracks for decorative effects. Species Oak, Fumed Oak, Oak ‘Old’ and Robinia are available as veneers, fleece reinforced veneer decks or as veneered panels. Panel cores are chipboard, MDF, blockboard plywood, et cetera. The colour of the subsoil is generally brown or black.
