20mm engineered flooring is one of the most popular flooring thicknesses, and the thickest engineered flooring we sell. It is just as thick as the some of the thickest solid wood flooring we sell, but with different practical benefits, such as a better ability to handle moisture, and changes in humidity or temperature. 20mm refers to the thickness of the entire board. Wear layers will vary based on the product, but ours range from 4mm-6mm. This figure determines how much you can sand the floor down, whereas the overall thickness determines how long the floor will last, and how durable it is.
