Cork is an impermeable, bouyant, cellular material harvested from the bark of Quercus suber (cork oak
tree) grown in Portugal, Spain and other areas. It is harvested in a sustainable, environmentally friendly
way. Starting when the tree is about 25 years old, the bark is removed from the tree trunks every 9 years
without causing permanent damage to the tree. Cork oak trees live about 200 years. Cork products are
easily recycled into other cork products.
