Evora Cork Flooring includes an integral 1.2 mm (approx. 1/16") cork underlayment. Including the underlayment as part of the flooring makes installation faster and easier and eliminates the inconvenience of purchasing multiple products and calculating multiple coverages. Additionally, because the Nano Collection uses the UNICLIC glueless click locking system, your cork flooring can be disassembled to replace damaged planks, or to move the flooring to another location. By integrating the underlayment with the product, the underlayment moves with the product and there is no need to try to move or re-use separate underlay.
