What is Cork Flooring?
Cork flooring is an Earth friendly material created from the cork bark of trees. The main tree that is used is called the “cork oak", also known as quercus suber. This tree is native to the Mediterranean area of the world and is harvested mainly from Spain, Portugal, France and Italy. It is interesting to note that harvesting cork is only done after a tree matures to being twenty-five years old.
Once the cork material is harvested from the trees it is then washed, stripped from the harder outer bark and boiled down. The boiled cork is then drained and set into slab shapes. The slabs are holed punched for stoppers but the resulting cork scrap is where the flooring comes from. To create natural cork flooring, non toxic scrap cork is ground back up and baked into blocks. Those blocks of cork can be organically dyed in various colors offering a myriad of flooring choices.
Beyond the ideal of safe and sustainable flooring, cork floors offer a wide range of bonuses. The flooring is water, gas and stain resistant. Because of the water resistance the flooring is also mold resistant, will not rot and is naturally resistant to termites. The resistance of natural cork flooring created this way allows for no harmful chemicals in the home.
