Rolled noise -insulating substrate fits simply and quickly

An alternative to the two previous options is a "floating floor". Similar noise insulation for the floor will solve the problem with impact exposure to noise. The uniqueness of this method lies in the fact that the insulating layer has no mechanical connection with the walls or inter -story ceilings. And this, in turn, allows you to isolate the apartment from external sounds by preventing vibration. It is due to this that effective sound insulation of the floor under the screed is ensured.
