What is the difference between 6mm, 7mm, and 8mm laminate flooring?

What is the difference between 6mm, 7mm, and 8mm laminate flooring? Laminate flooring is available in a number of thicknesses. Measured in millimeters, laminate flooring can range from 6mm to 12mm thick. The difference between 6mm, 7mm, and 8mm laminate flooring is simply the thickness. When deciding what laminate is right for you, remember that thickness does  not determine durability. Durability of a laminate floor is measured by the AC rating, which rated the wear layer. The higher an AC rating is, the more durable the floor will be.

The Differences Between Thicknesses

6mm laminate flooring is the thinnest option. It is easy to assume that since the laminate is thin, it is not as durable. This assumption is not true, as thin laminate can have outstanding performance. When installed over a sturdy subfloor such as cement, thin laminate becomes very strong and durable. Be sure to check that the AC Rating will stand up to what you need.

7mm laminate flooring is ever slightly thicker than 6mm laminate flooring and is ideal for normal home installations. When installed over a quality subfloor with the right type of underlayment, 7mm laminate flooring has outstanding performance. Remember to be aware of the AC rating of your floor. The higher the AC rating, the more durable the wear layer on top of the floor will be.

8mm laminate floor is one of the most popular flooring options. It seems to be the happy medium between thick and thin laminate flooring options and provides ideal stability and easy installation. The 8mm thickness is enough to overcome any subfloor imperfections and create a sleek flooring solution.

    Is it ok to add 8mm thick laminate flooring to our current 7 mm laminate flooring. Both are Quick Step locking.

      I am not sure exactly what you are asking, Armando, but I will do my best to answer your question.

      If you are asking if you can add 8mm laminate on top of your currently installed 7mm laminate flooring, the answer is no. You should remove the old laminate flooring first before installing the new laminate flooring, especially if your 7mm laminate is installed as a floating floor. You cannot install two floating floors on top of each other.

      If you are asking if you can lock in new 8mm laminate to your old 7mm laminate, as an addition, such as you are only installing new floor in your living room, but leaving the old laminate in your kitchen. You would need a transition molding to cover the space in between the 7mm laminate and the 8mm laminate. Because the two floors are different heights, they will not lock together properly, even if they are the same locking system.

      I hope this answers your question! If you need any further assistance, please feel free to email us at or give us a call at 1-800-520-0961!
