For roof insulation, we need to use high-density boards. Although it is different from the exterior wall construction, it needs to bear the pressure of people's activities on it. Therefore, it is necessary to use high-density boards to insulate the floor. Floor insulation means that the sun cannot directly contact the floor, so that it cannot continuously irradiate the concrete layer of the fl...
