When arranging a traditional softwood floor on the ceiling between the storeys, we must think about ensuring proper sound insulation.. For this purpose, strips of a suitably impregnated soft fiberboard are placed under the joists. Other materials can be used. Such pads will prevent the transmission of sounds. It is necessary, because an ordinary softwood floor is a kind of soundboard. It is also good to insert mineral or glass wool boards between the joists.
