If from city bustle or loud neighbors do not save their own walls, then it's time to think about sound insulation. From the noise of the included drill, loud music, or the clarification of relations behind the walls of residents of high-rise buildings, only special construction materials that prevent the penetration of unwanted sounds into the dwelling will be saved.
What are the materials for soundproofing
Thin walls, through which there are various kinds of noise and creates an undesirable acoustic effect, force the use of sound-absorbing and noise-insulating material. The choice of sound insulation determines the nature of the noise, which is of the following types:
- Air( running household appliances, barking dogs, driving cars outside the window) is the most common type of noise that causes discomfort. To solve the problem, materials with the Rw index help.
- Impact( drilling, nailing, knocking of heels) occurs when striking a structure, causing sound vibrations that are able to spread far to adjacent elements. When choosing materials to solve the problem, one should focus on the Lnw index.
- Structural( growling water, tapping in the batteries, noise of the ventilation shaft) is formed due to the vibration of communications, but is transmitted through the structural details of the building.
The task for materials for soundproofing is to create a reliable barrier to any kind of noise, do not allow them to enter the room or absorb. A successful solution assumes that it is better to use different materials for this, for example, mineral wool, fibrolite, multilayer panels, a cork, sealant, but there is a risk of creating a cumbersome design or large financial costs. When choosing the right material, you should give preference to those that have a high index of sound insulation, sound absorption, minimum thickness, simple installation.
Sound insulation materials for walls
Why are concrete, brick or foam walls not always safe from noisy neighbors? They are "rigid" in structure, therefore reflect sound fluctuations."Soft" soundproof materials for walls with cellular, fibrous, granular structure absorb them, while representatives of a new generation, such as Tecsound, PhoneStar, Sonoplat do it at the highest level and without losing any useful space. High coefficient of sound insulation( up to 70 dB) is achieved thanks to an innovative polymer, and in combination with the sound absorption function they provide maximum comfort.
The materials for the ceiling in the apartment
This is another nuance on the way to a quiet life and a comfortable atmosphere in the apartment. Choosing noise insulation materials for walls, it is not necessary to leave the ceiling unattended. The ideal option is when the neighbors from above take care that the slab on their side, where the floor is, is soundproofed. Less favorable solution to a complex problem involves the creation of a frame structure with plasterboard and mineral wool inside. Even for noise insulation of the ceiling use thermo sound or ZIPS, but they are unpopular because of the high cost.
How to choose materials for soundproofing of walls and ceiling
Finding soundproof materials for walls and ceilings will not cause much trouble, but the choice in favor of this or that option will not be easy. What will help to reduce noise level, thus will not cause fears about harm to health? When choosing it is necessary to take into account not only price, quality, but also important factors to choose the right sound insulation materials for walls and ceilings.
- Thickness of the material.
- The efficiency coefficient, with the indicator closer to 1, the better insulator for unwanted sounds will be the selected material. For example, the brick has a coefficient of 0.05, carpet with pile and cork - 0.2, sound-proof panels for walls - 0.7.
- The level of flammability of the material, how toxic it will be in case of fire. Environmentally friendly and non-combustible materials - mineral wool, cork, sealing self-adhesive film, and polyurethane foam, vinyl when burning will release harmful substances.
The best materials for soundproofing the
ceiling. Alternatives to plasterboard sheathing, as the best insulating material for the ceiling, will not be easy to find, because neither suspended acoustic structures nor stretch ceilings have such qualities. But to absorb noise, sound will have to look for a suitable option among soft, semi-rigid or hard materials:
- Soft( jute, felt, fiberglass, soundproof membranes).ACOUSTIC BATTS, TOPSILENT BITEX, ThermoSonicIsol, Texaund 70 are characterized by their low weight and high degree of sound absorption up to 70%.
- Semi-rigid( pressed plates based on fiberglass, mineral wool with polyurethane foam).SoundGuard Basalt, MaxForte-EcoAcoustic, Schumanet have a cellular structure, and the degree of sound absorption varies in the range of 50-70%.
- Hard( granulated mineral wool, pumice, vermiculite).IZOVOL, Rockwool, Knauf have a porous structure and are capable of absorbing sounds at 50%.
Where to buy and how much are the
The building materials market does not have a shortage of offers regarding the choice of both the properties and the price of products that act as a soundproofing device. Foreign or domestic manufacturers offer their products directly, through intermediaries, retail networks or the Internet. Often, sound insulation materials for walls and ceilings have to be chosen among a huge number of proposals, with the average price range is very wide - from 150 to 1300 rubles per 1 sq. Km.m
The minimum cost of soundproof materials taking into account the thickness is as follows:
| Thickness( mm) | Price( in rubles) |
| 5 | 900 |
| 10 | 175 |
| 12 | 230 |
| 15 | 280 |

Reviews
Vyatcheslav, 38 : In a small room decided to make a bedroom, but one wallbordered on the porch and the audibility was that still. I had to do plasterboard plastering, a layer of cotton wool was laid inside. Excellent helped: no unnecessary sounds, and the loss of almost 10 cm because of the frame I do not consider critical when it comes to quietly fall asleep in silence.
Maxim, 29 years : I would recommend foam thermocom instead of mineral wool for soundproofing. It has less harmful substances, it's thin, it's easy to pack it. For houses with brick walls or for gypsum plasterboard walls, you can select EcoTish. This soundproof material can be used as a filler, and as an interlayer.
Vadim, 41 year : If you need to make a good noise block against not too quiet neighbors, then only the profile construction, drywall, special tape and minvate. Penofol does not give a good effect, extinguishes a minimum and almost does not affect the noise level. Cork or other soundproofing plates for walls are not a panacea, although they absorb sound well, and at cost - an extra waste of money.
