Most people on planet Earth try to make their housing as cozy and comfortable as possible. If in the early periods of the formation of civilization the main emphasis was on security, then today the safety of housing has faded into the background. Few people can now imagine that once there were no sexes in the houses. Even in the houses and castles of the nobility and aristocracy, the floor did not lay the floor from the very moment of the collapse of ancient states (there was a stone floor) to the era of the Renaissance. It was during this period of time that parquet and the so -called floorboard appeared. Satven board – this is a building material for laying the floor. This material is made from durable varieties of wood, almost all varieties except linden and poplar. Some types of wood, such as aspen, pine and alder, require additional processing by persistent paintwork, otherwise they cannot make the floorboard from them. Satven board its price, by the way, unlike a number of other building materials that are used for the manufacture of the floor an order of magnitude higher, but it has a number of advantages. For example, the floorboard retains heat and has anti -allergic properties. In addition, this building material is absolutely environmentally friendly and, accordingly, harmless to human health. Installation can be carried out on a concrete or plywood base, on the already existing floor and on carrying wooden structures. Installation of the floorboard today is a profitable business. In our country, the sexual board was widespread only in the 90s of the twentieth century, and in the country it practically does not produce. That is why the Polish sexual board was distributed, which is not inferior in quality to the best samples of the sexual board from Europe. Paul from such material will be indispensable in any housing.
