We have now been able to expand our popular 'Supreme' engineered wood flooring range after continuous demands to include 21mm American black walnut flooring. As with all of the boards in the 'Supreme' range, this high spec flooring has an overall thickness of 21mm with a 6mm solid wear layer of solid hardwood on the top surface. Underneath the 6mm of walnut is a 10 layer multi-laminate hardwood ply which is what gives the boards a vast amount of strength and stability. American black walnut is one of the most stunning materials used for flooring. The deep, rich colour with beautiful decorative grain that American walnut has to offer provides a real touch of class to your property. Coming in at 190mm wide and 1900mm long with a 6mm wear layer of walnut you will be hard pushed to find a walnut floor made to this specification at a better price than this.
