Apartment soundproofing has become an integral part of the repair works today. The low quality construction and the improper layout, as well as the use of the modern powerful speakers, result in the necessity of the noise insulation.

Apartment soundproofing may be made preventively or after-the-fact. In the first case, the potential noises of the new apartment are not yet known. In this instance, the acoustic engineer analyzes the layout of an apartment and the calculated characteristics of its walls and floor structures to make a decision on the optimal design for a particular apartment.

The similar procedure should be followed in the second case for after-the-fact soundproofing. The difference is that the type and the level of the disturbing noise is already known.

Before starting the work, make a decision on where the sound insulation should be necessary: throughout the whole apartment or in some rooms only, for example, in the bedroom. It is clear that the overall soundproofing will provide high acoustic comfort throughout your apartment, but the financial issues should also be taken into consideration. With a small budget, you can only soundproof the rooms (the bedrooms, a nursery). A compromise option is often used when different level of soundproofing is provided for each room depending on its purpose. Depending on your budget, the MaxForte experts will offer you the most suitable option of sound insulation to achieve the comfortable conditions on the largest possible area.

Complex soundproofing of an apartment requires that all subtleties and nuances of a particular premise were taken into account. For example, the sound insulation for the floor should be chosen depending on the carrying capacity of the floor structures in the house: the wooden floor structures of the old housing stock cannot bear the “floating” screed because of high loads. And when choosing the sound insulation for the walls, it is necessary to take into consideration the walls structure and the expected loads on walls.

If necessary, our acousticians will draft a free design clearly showing the types and the locations of sound insulation products to be applied (with a rationale for the made solution) as well as the detailed calculation of the required materials.

In the apartment buildings, the apartment enclosing surfaces (walls and floors/ceilings) are of a uniform structure. The soundproofing capability of single-layer barriers is determined by their mass and internal losses. It is never sufficient in real-life situations! Good soundproofing requires the higher consumption of building materials and increases the weight of the house (and therefore demands a stronger foundation). So the pursuit of the additional decibels is not economically beneficial for the developers.

We found out that increasing sound insulation by only escalating the weight is unprofitable and impossible due to weight restrictions. That’s why the multilayer systems are used for apartments soundproofing. The idea is to attach the additional layers to the existing enclosing surfaces (walls, ceilings or floors).

The alternation of soft sound-absorbing and solid soundproofing layers creates a complex interference pattern: the multiple reflections and retractions of sound wave at the inter-layer boundaries make it losing the energy each time!

The practical way to improve the sound insulation of the apartments is to use the three-layer cladding: weight No.1 - resilient element - weight No.2.

Weight No.1 is the existing enclosure (floor, wall or ceiling).

Resilient element is the layer of MaxForte sound-absorbing materials.

Weight No.2 is the extra cladding of drywall on the walls/ceiling (or the screed on the floor).

This simple formula allows to improve dramatically the noise insulation of the apartment with the minimum area loss!


The modern houses apartments soundproofing is performed in two stages. At the first stage, the sound isolation of the floor is mounted: the builders place the sound-absorbing materials and pour the so called “floating” screed over them.

When the "floating" floor is arranged it is critical that the screed should not touch the walls. Otherwise the contact points between the screed and the building will be covered with acoustic bridges significantly reducing the sound insulation. Be sure to bend the sound insulation to the walls or use the special edge stripping to arrange vibration isolation between the screed and the walls!

On the second stage, the sound insulation of the ceiling and the walls is mounted. Ceiling and walls soundproofing is described in the relevant sections. All the structures are based on KNAUF dry construction designs therefore the sound insulation may be mounted by your own workers. Being minimum 4 cm thick, the walls and ceiling sound insulation cuts off the most part of the domestic noises (like talks, screaming or TV). Sound insulation against low-frequency noises (from stereo system or home theater) "consumes" about 7-8 cm of space.

The cladding not only increases the sound insulation but also levels the insulated surfaces so saving significantly the cost of finishing the apartment: you don’t need to buy the plaster and the glass-fiber mats or to pay the builders for levelling the walls and the ceiling! Due to high carrying capacity, the cladding may be used for securing even the heavy interior design items, such as: shelves, kitchen cabinets, TV.

Since the floor soundproofing works include the wet works (the screed is poured), it is a good reason to order the floor sound insulation first and then to buy the rest of the materials for the ceiling and the walls after the screed becomes dry. Indeed, all the unused materials in the apartment will be the obstacle for the workers when applying the “floating” screed. So the apartment should not be blocked.


In conclusion, it should be noted again that no soundproofing solutions based on thin structures can exist. No wallpapers, cork backerboards or “soundproofing” membranes will save you from the noise from your neighbors. If there were any opportunity to increase sound insulation without loss of area (or height), our company would deal only with such structures! However, the miracles do not happen, that’s why the time-tested solutions are used for apartments soundproofing. By the way, exactly the same multilayered claddings are used in recording studios and cinemas, although the sound insulation can reach there the thickness of several tens of centimeters!


Imagine that you are having a dinner in a restaurant with your loved one and at some point a noisy company appears at the next table and starts shouting and laughing loudly. Under such circumstances, nobody can enjoy a dinner and the party will be spoiled! The life in an apartment building is similar to a restaurant with the apartments instead the tables. We believe that our apartment is a house which must be free from the ambient noises. The soundproofing issue arises often after settling in the apartment. The people start living in a new apartment and find out that they can hear the conversations of neighbors who live behind the wall and tramping from the upstairs. If so, it is clear that neither an expensive finishing materials based design nor the exclusive furnishings will bring a delight. High quality MaxForte sound insulation will provide you not only a dry increase in decibels, but also a comfort and a harmony for your home!
