Renew or replace any torn or worn board with natural cork panels, available in two varieties. Cork is an environmentally friendly, naturally renewable resource. Harvested from trees that are stripped of their bark when they are 15 to 20 years old, cork is taken with carefully made 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. Natural Add-Cork Panels feature a durable tackable layer of .13" natural cork bonded to .38" lightweight tackable core material. Natural Cork-Plate Panels are the ultimate in tack surfaces, featuring a layer of .25" natural cork laminated to .25" moisture-resistant rigid core material. Natural cork material also available in roll form, either cut to size or in precut sizes. Adhesive for rolls sold separately. Please add fiberboard or other appropriate backer to allow for use as tack surface. 10 year guarantee. TAA compliant.
