Cork, an exceptional raw material
Cork comes from the bark of the cork oak tree (Quercus Suber L). It is a plant tissue, 100% natural, which covers the trunk and branches.
It consists of a honeycomb-like structure of microscopic cells filled with an air-like gas and coated mainly with suberin and lignin. One cubic centimetre of cork contains about 40 million cells.
Cork is known as “nature’s foam” due to its alveolar C structure. Cork is lightweight, airtight, watertight, resistant or w. k ce vie to acids, fuels, and oils and impervious to rotting. ll microscopic
Cork is sustainably harvested by specialized professionals without damaging the trunk. The cork oak tree re-grows the outer bark layer and is harvested every 9 years. Over the course of its lifetime, which lasts about 200 years, the bark will be harvested 17-20 times. Cork is a natural material which is both renewable and recyclable.
