In our project, we show you how to install natural 12-in. unfinished cork tile over a sound plywood underlayment. This is just one of a wide variety of cork flooring products that are available.

This flooring is "floated" in that it is not glued or nailed directly to the subfloor, but laid on an underlayment -- in our example, cork, although 1/8-inch foam is also used.

Most residential cork flooring uses 1-foot-square tiles with natural earth-tone colors. These can range from almost white, such as a wine bottle cork color, to deep brown or almost black.
