Whether you live near an airport or in a suburban neighborhood, noise can become an intense source of daily stress. You can be the main source of noise yourself, like musicians, for example, which can lead to tensions with your neighbors. Understanding how sound insulation works is therefore essential to protect yourself from noise. Find more articles on the theme: Insulation
The fundamentals of sound insulation
Sound is a vibration that first spreads through the air. The vibration is transmitted from molecules to molecules if nothing stops it. It can also travel thanks to sound conductors like concrete or tiles. Thus, if you do not insulate your home, concrete, bricks or wood will not alone be able to protect against outside noise. It is also important to note that where the air passes, the noise passes: thus the windows which let pass a draft will also let pass the noise. In addition, the thicker a material, the greater its ability to stop vibrations, this is called the mass effect. It should also be borne in mind that noise can circulate inside the accommodation between the different rooms, which seriously affects the comfort of the family.
First, consider installing new windows, double or triple glazing. Thus a large part of the outside air and therefore of the noise will be blocked by efficient windows. The installation of new windows may be subject to a tax credit. The second step is the use of thick carpets in the bedrooms to prevent house noise from circulating, you will also gain a lot in comfort. You should also think about creating thick partitions using polystyrene panels for example.
Sound insulation and thermal insulation
Sound insulation is almost always accompanied by thermal insulation when it comes to insulating against external noise. Rock wool and glass wool, because they are thick, can serve this double purpose. Attention, do not leave empty space, the air could penetrate there and thus cancel the insulation. Polyurethane composite foams are light and can be placed on the inside, which allows insulation during renovation work by limiting the space lost. Also remember to identify where outside noise comes from. If they are aerial in the case of a nearby airport, insulate the roof with a thicker layer of glass wool in the attic. If noise is coming from the road, insulate the walls more effectively. But keep in mind that a sound and thermal insulation will make you comfortable and energy saved the efforts provided!
