6mm Thick Cork Underlay

Natural cork underlay provide exceptional sound reduction capabilities in addition to insulation and comfort underfoot. The cork is harvested from the bark of the Cork Oak tree without harm to the tree. An environmentally friendly option for naturally healthy living. Cork quiets both hardwood and laminate floors. The noise of foot traffic in the installed room and adjacent rooms alike are reduced. Cork can be used above, below and on grade. When installing over concrete floors you must purchase an additional moisture barrier for use with cork underlay.
