What is cork?

Cork is a renewable and recyclable material that is increasingly found in construction.

Cork comes from the bark of the cork oak, a tree that grows in the Mediterranean region. Portugal accounts for around 50% of world production. This country even has laws that have protected these trees since the 14th century. Spain produces around 25% and France, Morocco, Italy and Tunisia are the other producing countries which share this market.

The first harvest of cork oak bark is done when the tree is about 20-25 years old. This harvest gives a more irregular cork, used mainly for building materials, furniture and accessories.

This bark is removed by hand using an axe, mainly around the trunk, which does not harm the tree. The bark will regenerate and can be harvested approximately every nine years. The new bark will have a smoother texture and better quality cork.

A typical tree produces several hundred kilos of cork and its lifespan is around 200 years and even more. It will be possible to make about twenty harvests per tree, without harming it. After this age, he will be replaced by a younger one.

Cork has a structure composed of mini-cells, this membrane is flexible, waterproof, light, elastic. Cork floats, it is compressible and returns to its initial shape following pressure. It does not mold, it is hypoallergenic, antimicrobial, antifungal and resistant to wear.

It is a good insulating material, both thermal and acoustic. It is also a good insulator against fire because it does not propagate flame or gas under combustion.



For some years it has been used in the construction of ecological houses. It is found either in pellets or in panels as insulation for walls, roofs, basements, attics.

It is increasingly popular as a floor covering in the kitchen as well as in a bedroom or living room. Tiles or slats are now being made that fit together without glue like a floating floor. It gives a feeling of warmth and it is comfortable under our feet due to its flexibility.

Other cork products are now popular in home improvement such as wall tiles that stick directly to the wall. There are cork upholstery with different patterns and colors that give a touch of originality to your interior. It is also made into stair treads, decorative accessories and it is also an important element in the composition of linoleum.

It is a versatile material that deserves to be used in this period where we are more and more concerned about making the right choices for our environment.
