Natural wood parquet floors are multilayer, which in their thickness consist of two parts. The upper layer in them is a layer of high -quality wood of a valuable breed, and its lower part consists of two layers of wood, in which the fibers are located in different directions. For the lower part, pine is more often used. By the way such a parquet is made, and in structure it is divided into parquet Tangential and parquet radial. They are distinguished by orientation of annual rings on a tree. The rings of the tangential parquet are on the front surface at an angle, and have an irrelevant shape of the oval.
