Cork is a 100% natural material, biodegradable, and environmentally friendly.
Cork is an impermeable buoyant material that is harvested form the bark of the Cork Oak Tree. Those trees grow in southwest Europe and northwest Africa, with Portugal having almost 50% of the world production of cork in the world.
Bark is stripped from the trees when they are 25 years of age. Every nine years there is new bark to be harvested. The first two harvests are generally of a lower quality. The cork tree can live for about 300 years and is the only tree whose bark regenerates itself after each extraction. With this awareness that the cork industry is regarded as environmentally friendly and sustainable since the cork tree is not cut down to obtain the cork it is a great alternative to material that is harvested by cutting down trees. Also, cork can easily be recycled.
Properties of cork materials:
- matte appearance
- lightweight material, that is soft to the touch
- fire resistant and flame retardant
- water resistant and repellent
- stain resistant
- scratch resistant
- mosquito repellent
- durable
- environmentally renewable
- natural resource
The extractors who are specialized in removing the bark are using a special designed hatchet to slice through the cork layer on the trunk of the tree. It is a process that doesn't harm the tree and is renewable. The cork planks are stacked outdoors for a few weeks to six months. The air, sun, and rain improve the quality of the cork. After this period, heat and water are used to remove the dirt and tannin from the planks to make the cork softer and more flexible. The outer layer, which is poor quality, is scraped off.
The planks are stacked in a dark, humidity-controlled cellar for a few weeks to dry and cure. They will be trimmed to a uniform, rectangular shape and sorted by quality. Since cork is a natural product it requires very little processing.
Cork has been used since ages: Cork bottle stoppers have been found in Egyptian tombs, the ancient Greek used it to make fishing net floats and sandals. The Romans used it to make life jackets for fishermen. And the people living in the regions where cork is produced have been using it as building material for centuries. Cork used as roofing material would be perfect to keep the heat out in the summer. In winter it would keep the cold out. Cork used on floors would provide a soft walking surface.
