Cork flooring, although offering water resistant features, is not waterproof. Although durable and low maintenance, the liquid can find its way through cracks and crevices. Cork flooring comes in different thicknesses, with the most common ranging from ¼ inch to ½ inch.

Cork is among the most eco-friendly flooring solutions there are. Where certain hardwood and other wood flooring products have a reputation for being hard on mother nature, cork comes from the bark of a tree, and the process of removing the bark does not kill the tree. That makes cork completely renewable and sustainable, as one tree can repeatedly generate the material needed to produce the flooring.

Cork is also considered to be hypoallergenic with anti-microbial properties and mold and mildew resistance benefits. It also repels dirt, dander, and dust mites - making a great choice for allergy sufferers. It’s also a low maintenance flooring choice that is soft and comfortable underfoot.

What Is Cork Flooring?

If green and eco-friendly products are what you desire for your home, cork is a perfect choice. Cork is all-natural, being harvested from the renewable bark of the cork oak tree. As previously mentioned, the trees are not damaged during the harvest, so this 100 percent eco-friendly product meets the requirements to protect and conserve the environment.

In cork oak plantations, the bark will not be harvested from a tree until it is 25 years old. The cork oaks are stripped of their bark by hand, and the bark grows back after each harvest, taking on a smoother texture each time. A cork oak can live for up to 200 years, but stripping the bark only happens once every nine years. Throughout their long lives, cork oaks can be harvested up to 20 times - making it a truly inexhaustible resource.

Cork´s structure is very similar to that of a honeycomb, and every cubic centimeter boasts around 40 million cells. The cells and the spaces between them are filled with a gaseous mixture similar to air, which makes cork flooring warm, elastic, and sound absorbent.

Greatmats offers many cork flooring products for sale, with the four most popular ranging in thickness and features. These five products include:

  2. Cork Underlayment 4x50 Ft. - 3 mm thick
