I was in yoga class the other day desperately trying to concentrate on something other than the muscles burning in my legs when I looked down and started thinking about the cork floor they have in the studio. It’s really nice. Chances are you have heard or read something about cork flooring lately. It’s being touted for its eco-friendly properties, versatility and resilience. But I bet most people still don’t know enough about cork to give it serious consideration when exploring flooring options. So here’s a primer on where it comes from, how its manufactured, what it costs and how you can integrate it into your own home design.
Where Does Cork Come From?
It’s the outer layer of the cork oak tree that grows in the Mediterranean area. It is light colored, insulative and very sound absorbent. The type we use as flooring is indeed the same as the cork in your wine bottle. The bark naturally splits every 9-15 years and can be harvested safely without harming the trees. The trees can live up to 500 years making it a sustainable and renewable resource. Portugal is home to 30% of the world’s cork trees and produces 70% of the cork worldwide.

I love the exotic look of Ardosia from epanko. It's available from 12"x12" up to 12"x36".
What Makes Cork a Great Flooring Material?
- Comfort- It feels great to walk on because it is naturally shock absorbent.
- Durability – It can be compressed up to 40% (by high heels and heavy furniture) and return to its natural shape.
- Impermeable- It is naturally resistant to liquids.
- Low Maintenance- Cleaning instructions vary by manufacturer. All suggest regular sweeping/vacuuming but cleaning solutions recommendations vary.
- Hypo-allergenic- It does not absorb dust so it’s great for people with allergies or asthma. Suberin is a waxy substance in cork that naturally repels insects, mites and mold.
- Eco-Friendly – It comes from the earth and can be recycled. Just opt for low- or no-VOC sealents.
Where Should You Use Cork in Your Home?
You can use Cork just about anywhere in your home. It’s great for kitchens or anywhere you are on your feet for extended periods of time because of it’s soft feel. I also like it for kids rooms and recreation rooms because it’s soft and durable. It can also be used in high humidity areas such as bathrooms, basements and laundry rooms but standing water can damage it so be careful. Since it’s a natural material, it can fade, so it should not be exposed to direct sunlight for extended periods of time.

The small accent tiles in this kitchen tie the cork in with the traditional look.
What Designs and Finishes are Available?
In order to make floors, the cork is ground up in to pieces of varying sizes. The pieces are sorted by size or mixed together to form a variety of styles. Once you have chosen the style you like, then you can move on to color! If you are a purist you might want to stick with the natural, warm brown tone. But if you want to jazz it up, there is a rainbow of colors available. With tiles you can create any design you can dream up.
How does the Material Come and How is it Installed?
Cork Tiles
Cork tiles come in many shapes and sizes. Squares and rectangles start at 6″ and go up to 36″. Various shapes are available from hexagons to herringbone. Pretty much anything you could do with tile, you can do with cork.
They are cut to size and glued to a clean, even surface. Once the glue has dried, the floor is sanded and sealer is applied. There are many tiles available that are pre-finished. You cannot install cork tiles over other wood or tile floors. They must go directly onto the subflooring.

Interlocking Cork Panels
Cork Panels made like other laminate floors and are pre-finished. They have cork on the bottom, MDF, a cork core, a cork veneer and then an acrylic varnish. Because there are other materials involved, it’s important to speak to the manufacturer about all the components of the flooring material if you are looking for an eco-friendly product.
These panels require a floating floor installation. Depending on the product, you may be able to float it over a tile or wood floor. Some may require it be removed.
Whether you go with tiles or planks, always order an extra box or two for repairs down the line. Dye lots vary and you want repairs to blend in.

I love this rich color and pattern variation in Cordovan from Epanko.
How much does it cost?
The average cost of a cork floor is $5-$10 a square foot installed. As with any material, it can vary greatly (from $3-$22 per sq. ft.) depending on the quality and design. If you are an experienced do-it-yourselfer, you can save a couple of dollars per square foot by installing it yourself.
