It seems a minor problem for those who live in the countryside or have an independent residence with respect to the city but that of noise is an important and often unsolved issue that could be solved by exploiting plunder from a few euros. Who lives in a condominium, perhaps in the center, knows how important it is to carve out a moment of tranquility away from annoying sounds from annoying neighbors or, worse still, from the noise pollution of the roads.

A house in the city has its comforts and it is possible to increase the latter through works aimed at one complete renovation that implement works by sound insulation. Industry experts point out that each case stands alone and that interventions for the acoustic insulation of domestic environments may not always solve the problem definitively. In other words, everything depends on certain factors, such as the materials used in the construction phase of the building.

Although there are different regulations that define the minimum requirements for thepassive acoustic insulation of a structure (which goes alongside the laws governing noise pollution), recent buildings do not always fully comply with the current regulations, more than anything relying on a matter of saving on materials. It will then be the responsibility of the owner of one or more properties to face the cost of soundproofing the apartments because, after all, everyone chooses the company to which to entrust the interventions based on their budget and the result they want to achieve.

In this context, in fact, isolating a building intended for office use is a very different matter than a residential apartment where the tenant is presumed to spend most of the day, including evenings and holidays. Consequently, the predilection of this or that solution is left to free will, but in most cases many prefer to put off spending.

How much it costs to soundproof an apartment: techniques and materials for greater domestic comfort

To determine which are the best solutions for the sound insulation of the building it is good to know that the noise is transmitted in three ways: by vibrations, by internal movements and by air.

Le vibrations are those sounds, sometimes subtle and annoying at other times deafening and exhausting, caused for example by the engine of an operating appliance (may be the air conditioner, a malfunctioning boiler or a washing machine), from the plant of an industry whose installation it is just a few steps away from the house, from refrigerators or from the lift near the bedroom. The extent of the sound is perceptible even with the ears plugged because noise propagation mainly affects the structure of the building.

Some internal movements we have a daily example: the neighbor who moves the furniture, the lady in heels who walks around the house, the tenant of the sold apartment who is renovating the interior. They are loud noises, not necessarily continuous but that cause a certain annoyance if perpetrated during the first afternoon hours or in the middle of the night.

Finally the noises can be spread to by air: it is the example of the screams of two young people fighting on the street or of music heard at full volume. Also in this case it is sudden and sudden sounds, impossible to tolerate in particular hours of the day.


Another element to be reckoned with is to establish which room in the building requires thesoundproofing because it is more sensitive to external noise. Generally there are two (or three) domestic environments that sound badly tolerated and are those rooms dedicated to relaxation and rest of the person: bedroom, study and children's room are the areas that should be isolated with a radical intervention.

Deciding to proceed with sound insulation means facing a careful analysis in a sector in which the solutions seem to be many but the final result is little less than satisfactory. The advantages of correct sound insulation they can be multiple, all aimed at the right of everyone to live peacefully in their own environments. It will be possible to prevent the noises of neighbors but also those coming from the street without advancing the idea of ​​selling the apartment. It will be necessary to know the materials and carry out a restructuring that allows a correct acoustic insulation suitable to the expectations.

It is good to shed light on one aspect: solutions exist soundproofing and solutions soundproofing. Although the two terms seem to be synonyms, only the second is the one indicated for sound insulation. In fact the soundproofing is the ability of a material to absorb the noises coming from inside a structure, for example to optimize the acoustics of a room intended for the study of a musical instrument.

The sound insulation is, on the contrary, the ability of a material to isolate the sounds coming from the outside preventing them from propagating inside the home. Between the two alternatives only the soundproofing materials are indicated for the acoustic insulation of external noise. Several panels are available on the market to be installed inside one or more chambers made of different materials based on natural minerals, vegetable fibers and innovative technologies. The must it is glass wool or rock wool, but also gypsum, cotton fiber and mineral fibers combined with specific resins needed to absorb all types of noise in an optimal way.

In 'acoustic insulation materials they are therefore different from each other and designed to improve comfort within the rooms. In addition to synthetic products that are widely used, it is always possible to focus on 100% natural solutions, such as the cork. Fully recyclable, low-polluting and with zero environmental impact, cork offers satisfactory results and is an eco-compatible material that meets expectations eco-friendly.

Acoustic insulation can be realized in different ways, each of which is aimed at reducing the propagation of sounds coming by air, by movement or by vibration. The use of the panels can be considered suitable for thewall insulation if you want to drastically reduce the noises produced by vibration. These could derive from a railway or even from the appliances of the underlying store but, through an intervention , you will succeed in isolating also the noises of the neighbors.

In the perspective of one energy restructuring of the fixtures you can install soundproof windows and doors with double glasses of which the windows and French windows of many structures are equipped. Someone can even opt for triple glazing but in most cases the structure of the frames is in PVC or aluminum. Wood (a natural material suitable for every aesthetic requirement) is used to define the frame of a window, but what really matters is being able to eliminate any acoustic leak that facilitates the reverberation of sounds.

In other words, it is necessary to equip the windows, doors and French windows with sheaths that seal the doors during the closing of the windows, preventing the thin propagation of the whistles produced by the wind. On the market it is possible to find insulated blinds mainly designed to isolate the rooms especially at night: these are products always made with materials such as aluminum, PVC and wood, previously tested to accurately identify the absorbency degree of each panel.


In fact, any sound insulation work can be effective only after a careful analysis performed by a professional technician in the field. Someone could turn to DIY using sheaths to optimize the fixtures but bricolage is not always the best choice, even more so if you do not have the adequate knowledge on the materials to be used.

Beyond the materials and solutions on the market it is good to point out that, very often, the noise issue is an easily solved factor by performing some types of intervention. Sounds propagated by air, for example, can be reduced if insulation materials are used for elements such as roller shutter boxes, the front door frame, the roof which, in some cases, easily absorbs the noise of hail. These are obviously practical and inexpensive systems, to be adopted with the help of an expert and after having carried out an inspection.

I restructuring costs for sound insulation they vary according to the intervention necessary for the optimization of the environments, to the material that one intends to use and to the opportunity to change frames and doors and windows. The expense incurred represents a small amortizable investment either through the tax deductions developed by Government, and through an improvement in the quality of life. The law allows you to deduct the cost incurred for an amount equal to 50% as you can get the benefits on the purchase of materials if you have done the work privately. The acoustic improvement must be certified by a technician who deems the type of intervention to be suitable or unsuitable.

A final question must find an adequate answer: how to isolate from the noises of the neighbors? Never heard of the sound insulation of the security door? Most of the annoyances can come from the stairs like the noise of the elevator, the forced closing of the door and the trampling of people going up the steps. Even the rumors on the landing can be disruptive and in this regard there are armored doors, with sound insulation certification, able to isolate all the sounds coming from the hallway. These are products made up of frames and panels made of specific materials combined with sheaths that seal the door during closure.
