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 five most popular ranging in thickness and features. These five products include:

  1. FlexeCork Interlocking Cork Rubber Tile - ½ inch thick
  2. AcoustiCork Underlayment Roll - 6 mm thick

  4. Coffee Cork Laminate Flooring - ½ inch thick
  5. Rubber Flooring Rolls - 8 mm thick

How Thick Are Composite Cork Floors?



FlexeCork Interlocking Cork Rubber Tile is a ½ inch thick, high quality rubber cork flooring option. The tiles are 3x3 feet and made of high quality recycled rubber material that is mixed together with cork, which saves energy and reduces oil consumption. It also makes this particular product partially non absorbent.

There are a number of different colors and patterns available in this product, and the tiles are easy to assemble with their interlocking design. This makes for a quick DIY installation without the need for glue or adhesive.

This flooring is made in the USA and has a very low rubber smell. It's a great solution in any space where extreme use and abuse are present, or, where traditional resilient flooring is installed. Its non-skid properties, shock absorbency, wear resistance, fatigue relief, and sound absorption make it perfect for a gym, basement, office, or commercial setting.

To clean the tile, it can be damp mopped with hot water and a neutral ph cleaner. This low maintenance, versatile flooring is available at a cost of less than $7.50 per square foot, and it comes with a 5 year limited warranty.

Rubber Flooring Rolls with cork are 8 mm thick. This is a two-ply flooring system that combines 3mm of rubber with 5mm of cork rubber base. This provides superior durability, insulation, protection, and noise reduction to a subfloor in a gym or workout room; it even does a fabulous job protecting existing subfloors from potential damage caused by dropped weights and the weight of heavy exercise machines. It’s a great solution for weight rooms, gyms, golf areas, ice skating rinks, rec rooms, playrooms, warehouses, and industrial floors.

The top layer is 90 percent colored rubber with flecks that are distributed throughout the product. This low odor rubber option is not slippery - even when wet. It’s very durable and made in the USA.
