One of the most extraordinary raw-material in Nature

With a Millennial tradition, for many years that Portugal is the main source of cork production. Cork is the bark of the cork oak (Quercus Suber L.), which means it is a plant tissue 100% natural. It is formed by a honeycomb of microscopic cells filled with a gas similar to the air and lined mainly of suberin and lignin. A single cubic centimeter of cork includes almost 40 million cells, arranged in perpendicular spun to the trunk of the cork oak.

Removed every nine years without any trees being cut in the process, the cork gives origin to a myriad of products, from traditional to the most innovative and unexpected. Each cork oak tree takes 25 years to be harvested the first time and the cork removed in the first two harvests, as well as the cork removed by pruning the tree, results in a raw material for insulation, flooring and products to such diverse fields as construction, fashion or design.

The harvest is done by highly skilled professionals, always between May and August, when the tree is in a more active growth phase and becomes easier Cork extraction it without hurting the trunk. For being a renewable and recyclable product, it is regarded as a raw material of excellence with favorable consequences for natural resources and for Planet Earth.
