100 percent natural, reusable and recyclable, cork is, whether from the environmental, social or economic perspectives, one of the world's most versatile materials. It takes each cork oak 25 years before it can be stripped for the first time and it is only from the third stripping (at 43 years of age) that the cork, then known as «amadia», has the high standard of quality required for producing cork stoppers.

Cork harvesting is a sustainable and ancient practice that involves the careful removal of the bark from cork oak trees without damaging them. This process, which takes place every nine years, allows the cork to regenerate and gives rise to an endless array of products, from the traditional to the most innovative and unexpected.

The unique cellular structure of cork is what makes it such an effective sound insulator. The gaseous components contained in cork are enclosed in small, impermeable compartments, which are isolated from each other by a moisture-resistant substance.
Cork is a remarkable natural material that boasts excellent thermal insulation properties. The air trapped inside its cells makes it an efficient insulator, with very low thermal conductivity across a wide range of temperatures
Cork is also a natural fire retardant : it burns without a flame and does not emit toxic gases during combusition.
Cork is hypoallergenic because it does not absorb dust or other allergens like other materials. As a result, cork is a great choice for individuals who suffer from allergies or asthma.
• The density of cork is typically between 0.1 and 0.3 grams
per cubic centimeter (g/cm³), which is much lighter than most
other materials.
• The specific gravity of cork is usually between 0.14 and
0.24, which is also very low compared to other materials.
• Cork's lightness also makes it easy to handle and transport,
which can be an advantage in various applications.
Cork is known for its excellent impermeability to both liquids and gases. This property makes it highly resistant to moisture, which is essential for its durability and longevity. The impermeability of cork is due to the waxy substance called suberin that is present in its cell walls.
Cork's unique honeycomb structure provides it with a high degree of resilience and friction resistance. The gaseous components of cork are trapped within small, impermeable compartments, providing it with a cushioning effect.
Cork is elastic due to its unique cellular structure. The cork cells are filled with air, creating a complex network of pockets that can compress and expand. When pressure is applied to cork, the air in the cells is compressed, and the walls of the cells deform to accommodate the pressure. However, when the pressure is released, the walls of the cells return to their original shape.
