Natural cork tackboards are suitable for any classroom, library, or other space, dampening sound and adding texture as well as display space. Natural cork is an environmentally responsible and naturally renewable resource. Cork is harvested from a cork tree, stripped with careful cuts that do not harm the inner core of the tree. The cork bark regrows, and this process allows a useful life of more than 150 years for each tree. Our most economical and best value surface, Valu-Tak features 1/16 inch thick cork layer bonded to 7/16 inch lightweight and tackable substrate material.
