Laminate, linoleum or parquet can serve as flooring for such a floor. The simplest performance of such a sex is its coating in one board. You can lay boards after alignment and insulation of the floor is carried out. An even better option is to lay the floor on the lags. Lags create an air gap between the floor slabs and the floor surface. And the air is a good heat insulator. Lags can be made in the form of columns or wooden bars. These bars are located in rows along the perimeter of the room. In the corridor, the lags are laid in parallel to the walls, in the room — perpendicular to the window. Lags are made from spruce, treated with antiseptic drugs. Brutus for the lag should be well dried. All this is necessary for a longer service life. For the better strength of the floor, lags are installed at a distance of no more than 40 cm from each other. The thickness of the lag is 30mm. Lags are laid with level measurements, so that the floor does not have waves or bubbles. If a new house is being built, then there are several options for the installation of floors. For a house on a area with a low location of groundwater, it is possible to lay the floor right on the ground.
