About Organic Cork.
Cork is a natural plant tissue! Cork is the bark of the cork Oak, it’s harvested between May and August by specialised workers. When the tree reaches 25–30 years of age and about 60cm (24 in) in circumference, the cork can be removed for the first time and then, every 9 years. The Cork Oak lives for about 200 years (on average) witch means that it can be stripped for about 17 times. It’s the only tree whose bark regenerates.
Light because over 50% of its volume is air.
Elastic because when compressed on one side, does not increase in volume on another.
Impermeable, to liquids and gas, because of the suberin and ceroids contained in the cell walls.
Insulator, to temperature and sound, because has low conductivity to heat, noise and vibration.
Fire Retardant because it burns without flame.
Abrasion Resistant because of its honeycomb structure.
Hypoallergenic because it doesn’t absorb dust.
Because of these qualities organic cork is used in a large variety of products in construction, fashion, design, health, energy production and the aerospace industry. In its early years, the first two harvests as well as the cork removed from the base of the tree, are used as raw material, it’s only when the tree reaches 43 years, that the stripped bark is good enough to produce wine stoppers.
