When choosing a floorboard, pay attention to its thickness. Indeed, much depends on this parameter. Thus, the thickness of the floorboard determines, for example, the installation height of the entrance doors. In addition, when joining with ceramic tiles, they begin to lay tiles on the upper level of the parquet floor. And it is governed by the thickness of the board, the substrate and in some cases the leveling base. If the floors in the adjacent rooms turned out to be of different heights, use a special joint profile.
The board has three layers, perpendicular to each other with respect to each other. This increases the strength of the parquet, not allowing it to lose shape. If we consider the board, starting from the bottom, then first we will see its wooden base with a thickness of 8 to 10 mm. For its production, a well-dried spruce or other less valuable breed is taken. Next comes a dense wood HDF plate or a thin strip of coniferous wood, 13 to 20 mm in size. The board is finished with a facing layer from 3 to 6 mm thick. It is made from precious woods - birch, cherry, ash, oak, etc.
7 mm . The thinnest models of the floorboard are only 7 mm thick. This flooring is considered to be applicable only once - because you can not ottsiklyuchёsh and the surface can not be restored. Although, if only the top layer of lacquer has been erased, it can be restored. This parquet flooring is put on glue, mainly using in the nurseries, corridors and halls.
10 mm. The thickness of the floorboard 10 mm - quite sufficient for scraping. However, it is impossible to clean more than 2 millimeters of the upper layer. Because of this, lay such a board only on the ground, which is very carefully aligned.
12 mm. Approximately the same can be said about wood flooring 12 mm thick. In addition, it can already be laid on top of a warm floor, which is made on the basis of infrared elements.
15 mm. And what is the most popular thickness of the floorboard? The answer is simple - 15 mm. It can be mounted both on glue and with the help of locks. It is possible to remove the top layer (working) up to 5 mm, so it is quite possible to restore the appearance of the parquet more than once. In everyday life to use it most optimally.
20 mm. Board thickness of 20 mm is particularly durable. It is placed on the floor of offices and various public spaces.
22 mm. The thickest board is also suitable for public spaces - 22 mm thick. Laying it with a complex pattern is expensive and time consuming, so it is usually mounted in the simplest way - deck installation.
Usually, the instructions attached to the parquet say in what way and where it is best to lay it.
Remember: if the working layer of the floorboard is at least 6 mm, then you can sand the board 10 times, not less. So say the standards of GOST. Therefore, such a parquet can lie for 100 years.
The height of the parquet floor will not at all equal the thickness of the parquet boards - it will be larger. After all, it is necessary to take into account both the leveling layer and the substrate. For leveling it is common to use plywood 10 mm thick, which is able to make even and concrete floor with a slope, and wooden floor, cracked from time to time. One plywood sheet costs about $ 12 or $ 15. To this we add the price of glue for plywood - $ 5 per kilogram. That is how much glue goes on one sheet. Get decent additional costs.
When working with the floorboard for every 2 m², standards allow you to have a height difference of up to 2 mm (taking into account the shrinkage of the substrate and uneven ground). The correct thickness of the substrate under the floorboard - 2 mm. If you make it thicker, then soft material (cork or foam) will shrink and deform, and the locks of the parquet will begin to play and wear out. And it will not happen immediately, but only a few months later.
