Three-layer parquet boards are still one of the most popular types of wood flooring on the market. Their three-layer construction gives them stability and can be installed quickly and easily thanks to the integrated board locking system. The surface of such parquet boards is already treated with resistant oil or varnish at the factory, so they can be used immediately after laying. They have earned reliability among customers due to their quality, long service life and durability. Recently, however, they are still losing ground to innovative, more environmentally friendly three-layer cured wood parquet planks.
