At first, when a person began to equip his home, he paid little attention to the ceiling. And, in fact, in those first dwellings there were no ceilings in the form that we are used to. The main task during the construction was to build strong walls and cover with a reliable roof. Most likely, the beginning of the ceilings went from the moment when people decided to use the free space under the rafters. There were a lot of things in the household that needed to be put away for some time in a dry place. Then a flooring was made under the roof, which separated the space under the roof from the interior.
In most cases, such flooring was made of wood, since this material was light and allowed to keep the air dry. In addition, it was convenient to attach any devices to such a ceiling. Surely, many people know that until the end of the 19th century, baby cradles were hooked on ropes attached to hooks on the ceiling. But in the homes of wealthy people, the ceilings were already covered with a special composition and decorated with various paintings.
In modern multi-storey buildings, the ceiling is the ceiling, which, in turn, serves as the basis for the floor in the apartment on the floor above.
