Anyone can become a hostage to annoying noise. Just as anyone can be a victim of noisy neighbors, so can become a cause of their anxiety. The solution to the sore problem is ceiling sound insulation. Modern technologies are constantly offering new types of materials that help absorb sound waves. Soundproofing the ceiling in an apartment under a stretch ceiling is not particularly difficult, but requires a careful study of the basic concepts.

Soundproofing the ceiling in the apartment: the advantages of a stretch ceiling
The stretch ceiling itself already assumes a certain percentage of sound insulation. According to experts, it "dampens" about 5 dB. The air space between it and the concrete slab reduces the propagation of sound waves. Attaching it to walls rather than floor slabs also reduces sound propagation. Of course, suspended ceilings also have airspace. But here the system of profiles itself, on which the drywall is attached, will serve as a bridge for the propagation of sound.
It often happens that this quality of the stretch ceiling alone will not be enough. Therefore, we have to resort to various methods of solving this problem. Each of these methods differs in the choice of material. It is the material used that will become the fundamental criterion in the entire process of soundproofing the ceiling. In addition to the choice of material, you need to decide on its thickness. Its indicator directly proportionally reduces the noise in the home. Today's market offers the latest materials that are able to qualitatively reduce the volume of sounds and not take away such important centimeters.
Ceiling soundproofing materials
99% of noise reduction efficiency depends on the choice of material. In order to more reliably understand the principle of operation of the entire system, it is necessary to define and distinguish two concepts. There are sound-absorbing and sound-insulating materials.
Sound absorbing the material has a fibrous, porous, soft structure.First, braking occurs, and then the complete absorption of the sound wave. The fiber from which they are composed, with its properties, provides the desired result. These include mineral wool, basalt slabs, felt and synthetic winterizer slabs.
Soundproof - the opposite of the previous type according to the principle of action. Such material does not absorb, but reflects sound. It must be dense and strong in structure to reflect the wave, and she would not be able to swing it. These include brick, concrete, etc.
Helpful advice! The best method of using certain materials for soundproofing the ceiling in an apartment would be to use representatives of both categories at the same time.
A sandwich construction with a sound-absorbing material inside and surrounded by a massive sound-insulating material on the outside is the most advantageous in practice. This composite structure will significantly affect the noise reduction ratio. Sound absorption in general depends on the correct choice of material, its thickness and quality. The modern market offers both a lot of well-known and well-proven products, as well as many new ones that are just beginning to receive reviews: cork, membrane.
Mineral wool - a proven method of soundproofing under a stretch ceiling
Mineral wool is the first in the list of sound insulation materials. It should be noted that its use will give not only this effect, but also other advantages:
- good insulation;
- ease of installation;
- relatively inexpensive price.
The above qualities are very important at the stage of material selection. If we talk about the installation of noise insulation of the ceiling in the apartment with your own hands, then you will need to construct a wooden frame. The form of release of the insulating coating is a roll or mat. Their width determines the range of distances that each rail is located from each other. In order for the cotton wool to hold firmly to the ceiling, it must fit tightly under the slats with an interference fit. Therefore, the distance between them should be less than the width of the noise isolator. To reinsurance against its fall, experts sometimes practice nailing insulation with nails over its area.
The downside in the technical characteristics of mineral wool is its instability to moisture, under the influence of which it swells and loses its shape. The way out of the situation was the use of the following materials in the following sequence: waterproofing film, mineral wool, vapor barrier.
Important! Steam rising from inside the room threatens to damage the noise isolator. Therefore, the mineral sheet must be reliably protected from both sides.
Expanded polystyrene: the pros and cons of using it for stretch ceilings with sound insulation
High-quality sound insulation can be organized using a material such as expanded polystyrene. It is easy to use, has low thermal conductivity and vapor permeability. The technological process of its manufacture is the saturation of polystyrene balls with gas, as a result of which they increase in volume by a factor of 50 or more. This increase gives a high coefficient of elasticity, compression resistance and lightness. Ease of installation ensures its release in the form of plates, the thickness of which is from 2 to 10 cm. The sound absorption of expanded polystyrene also has a high level: from 23 to 25 dB. Fastening of expanded polystyrene plates to the surface of the interfloor overlap is carried out using special glue, "liquid nails", and polyurethane foam. For a stronger grip, "fungus" fasteners are used.
Soundproofing the ceiling in the apartment: modern materials
The latest production technologies in any area provide consumers with the opportunity to choose an alternative. For soundproofing the ceiling in an apartment under a stretch ceiling, such an option was the release of soundproofing membranes. A sound-insulating thin layer of such membranes will effectively cope with its task. Due to their small thickness, they are very advantageous in comparison with mineral wool and expanded polystyrene, which take up significant centimeters of ceiling height. Such acoustic membranes are made of natural aragonite material, therefore they have an extremely environmentally friendly composition. They are produced in the form of rolls, they are flexible and plastic, nevertheless, they are a rather dense type of insulator. Due to this combination of important technical characteristics, noise absorbing membranes are gaining in popularity.
Latest adaptations of the noise insulation process
Special fabric is a new word in sound insulation. The speaker system is a fabric with a huge number of holes. This micro-perforation is capable of excellent noise absorption. The sound wave is constantly reflected from each hole. At the same time, it loses energy until it completely extinguishes inside the polymer holes.
How to make ceiling soundproofing with cork
The cork coating has excellent soundproofing qualities. In addition, it has a number of other advantages:
- natural and environmentally friendly;
- has a low coefficient of thermal conductivity;
- has a high level of sound insulation (it should be noted that this material absorbs high-frequency waves better);
- soft, elastic, moisture resistant;
- thin, does not "take away" centimeters of the ceiling height.
It should be borne in mind that when using a cork coating for soundproofing the ceiling in an apartment, the price of the material itself will be quite tangible. You also need a more expensive special glue for mounting this material.
Soundproofing the ceiling in an apartment under a stretch ceiling: installation secrets and its pitfalls
Installation of soundproofing flow in an apartment under a stretch ceiling can be done in three ways:
- laying between the sheathing profile;
- fixing with dowels - "fungi".
The choice of installation method depends on the soundproofing material used, the design of the room, the desired result and the availability of utilities in the under-ceiling area (wiring, ventilation, etc.).
Before proceeding directly with the installation, the ceiling surface must be prepared. The carrier board should be carefully examined for cracks and holes, irregularities. Small cracks are simply putty, large ones can be sealed with polyurethane foam. Every seam must be perfectly smoothed. After this procedure, the floor should be well cleaned from dust and debris. A commonly used element in any construction field is a primer. It significantly increases the adhesion between the layers superimposed on each other.
Important! Don't forget about lighting. When making a soundproof ceiling, it is imperative to remove the hook. A chandelier will subsequently be mounted on it.
A separate issue for consideration will be the device of sound insulation in a house with wooden floors. It is usually done on the second floor. The floor of the second floor is the ceiling of the first. And any construction manipulations are easier to do with the floor than with the ceiling. The process goes like this: a crate is made of a wooden bar, into the cavity of which a sound insulator is laid. Granular sand is one such material. It has excellent sound absorption characteristics and is therefore used quite often.
How to make noise insulation in an apartment: frame and frameless method
The name of the first method makes it clear that its basis is a skeleton. Most often, a metal profile or a wooden bar is used for it. If you believe the reviews, many people make noise insulation of the ceiling by this method.
At the beginning of the work, markings are made around the entire perimeter of the ceiling. The parallel profiles should be approximately 60 cm apart. The distance from the extreme profile to the wall is no more than 10 cm. Holes are drilled, the entire lathing is installed and you can go directly to the laying of the sound-insulating material
The frameless method of soundproofing the ceiling in an apartment is less laborious than the previous one, since it completely excludes the installation of complex structures. During the work, special adhesive mixtures are used. Recently appeared innovations in the field of soundproofing materials have a distinctive feature: one of the sides is self-adhesive. Here it will be important to correctly and evenly press this side to the floor slab and everything will be ready in a very short period of time. It is this feature that is singled out as the biggest plus when choosing materials for soundproofing the ceiling in an apartment. Reviews guarantee that by spending money on their purchase, everyone can save a lot later. Since further installation does not require the purchase of absolutely any additional materials.
The second subspecies of the frameless method is the method of installation of sound insulation using dowels - "fungi". When using it, a rough marking is also required, additional gluing of the panels can be used. "Mushrooms" must be fixed at the corners of the slabs and, preferably, in the center.
High-quality noise insulation of ceilings in an apartment under a stretch ceiling should be performed as smoothly as possible, without cracks and gaps. This will make it possible to get the desired result. Following the above tips, you can do the noise insulation of ceilings with your own hands. And staying in your own home will only bring pleasure. “Loud” residents of the upper floor will no longer bother. At the same time, you can be calm that they will not find out all the details of your personal life.
