Why a parquet board is better than a laminate Dimensions (L × W× T) of parquet boards are as follows: 1800–2500 × 180–200 × 13–20 mm. On the side and end edges, grooves and ridges or tool joints are arranged. The manufacturing accuracy is so high that the joining is very tight, without backlash. First of all, let's make a reservation: we are not talking about an archaic parquet board, well known since the times of total shortage and, apparently, out of habit produced by a number of domestic enterprises, but about the product " high technologies ", completely devoid of the operational disadvantages of its predecessor. Among the innovations are the structure of the material, previously inaccessible wood species, the absence of finishing and finishing works, as well as simplified. Of course, after reading the instructions, it will be mastered not only by an adult, but also by a teenager. But first things first. Unlike old-style parquet boards, modern material consists of three, or rather four layers. Each performs a strictly defined function. The bottom, main layer is most often made of pine or spruce plywood.
The structure of the floorboard
Perpendicular to its fibers (which, by the way, andensures the strength and stability of the floorboard, as well as its increased resistance to changes in temperature and humidity) is a middle, stabilizing layer made of multilayer glued softwood or high density fibreboard. In the middle layer, grooves and ridges or locking connections are arranged in a special way. With their help, the individual elements of the flooring are assembled into a single unit. The direction of the fibers of the upper, working layer, or shirt, perpendicular to the middle and parallel to the bottom. This layer is a veneer about 0.5 mm thick or slats (slats) 2.2–6 mm thick, made of more expensive wood species: oak, ash, beech, cherry, pear, maple, bamboo, etc. 
For reference: the harder the wood, the longer it resists wear and, as a result, it has a longer service life. To describe the degree of hardness using the Brinell scale. In accordance with it, the durability of oak can be indirectly characterized by the numbers 2.9–3.7. The most durable will be an exotic jatoba tree, whose hardness lies in the range of 7–7.7. These layers are connected under high pressure, which provides the material with durability and wear resistance, polished, sometimes treated in a different, non-trivial way and coated with a fourth, finishing layer - varnish, wax or oil. Finishing protects the shirt from scratches and dirt, gives it an additional decorative effect. The basics of the latter lay the working layer.
