These 190mm wide planks are 14mm thick with a 3mm wear layer and a hardened oil finish. Bourne also has FSC certification, the environmental gold standard of the timber industry, and a hardened oil finish that combines a natural look with a subtle sheen. This oil-based finish has an outer layer that is hardened to give extra wear and splash resistance making it easy to maintain. Bourne can also be used as wall cladding.
