How to make sound insulation in the room yourself?
A little about the types of noise
To find out what kind of insulation on the ceiling in the apartment you need, it is necessary to determine the main type of sound vibrations to which you are exposed.
Most often in the apartment from above they can turn on the TV loudly, when pets live, barking or meowing can be heard from there, and conversations in raised tones can be heard through the entire thickness of the ceiling. Such noise is called air - it can quite effectively be extinguished by traditional building materials, such as concrete, cement-sand mortar and structural blocks.
However, if during the construction of the building the builders saved on the thickness of the floors, the insulation from the sound of the air transmission would be very bad.
In addition, there is another kind of unpleasant effects, from which the insulation of the ceiling of the apartment saves very rarely - they are represented by shock vibrations.
Each of us encountered such a variety of sounds - a neighbor in the apartment from above makes repairs, children run on the floor, furniture moves, a large mass of people stomps out loud, large objects fall.
Conventional materials do not create obstacles for such a method of noise propagation - on the contrary, they contribute to its amplification and transfer to surrounding objects.
For example, a chair falls in an apartment above you, while you hear a noise from below - this is always caused by the use of construction tools that freely conduct sounds and transmit them to surrounding surfaces.
To make sure of this, try putting your ear to the wall, when the sounds begin to come from above, you will feel tangible vibrations and hear everything as if you are in close proximity to their source.
To once again make your home as comfortable as possible, you need insulation for the ceiling of the apartment, which may have different types.
If the sound intensity,with which you have to fight, is small enough, then you can use a more dense finish - for example, multilayer wallpaper or polymer decorative panels.
Noise isolation will increase slightly, but in your apartment muffled sounds will still be clearly heard. In addition, alternative finishing materials do not save vibrations.
Noise insulation in this case is laid over the formed structure, which basically serves as a support for laying elastic material. Among the advantages of the stretch ceiling can be called ease of installation, as well as a small load on the structural elements of the building.
Drywall is heavier, but very durable and amenable to additional finishing with decorative materials.
Traditionally, insulation for the ceiling of the apartment is represented by mineral wool or similar materials created from fiberglass.
They are very light and easy to install - mineral wool can be purchased in long rolls of several tens of meters, and in compact mats, which can be raised to the height of the ceiling in the apartment with one hand.
In addition, they can be stitched together with each other with their own hands in order to exclude the possibility of the formation of cracks that let sounds through in the future. If you watch promotional videos from the main producers of glass and mineral fibers, you will find out that their additional advantages include effective isolation from cold and moisture.
Among the well-known brands are:
Alternative insulation on the ceiling in the apartment can be created from a special acoustic fabric, which is placed in several layers and contains many slots or holes. Such noise insulation acts like a car muffler - passing through the gaps, sound vibrations propagating through the air are repeatedly reflected from the layers of fabric and are gradually absorbed by it completely.
Quite similar to it in its properties and insulation of the ceiling of the apartment, created from cork mats. More information about the properties of the cork can be found in advertising and training videos, but it greatly exceeds all types of synthetic insulation of the ceiling in the apartment.
Among the shortcomings can be noted only the high cost and large mass. In addition, a cork devoid of a synthetic base is fragile enough - you need to install it yourself with the utmost care.
Features of prefab houses
A rather complicated type of work is insulation on the ceiling in an apartment located in a panel house built during the period 60-80. The problem is that the plates made at house-building factories by the method of vibropressing, very well carry out vibrations due to its high density and monolithic structure.
Their insulation is so inefficient that when you move the chair from above you can hear a strong gnash not only from the right direction, but also from the walls and the floor.
Simple additional processing of the ceiling will not work out - it is necessary to turn your apartment into a real closed capsule, otherwise the sounds will still be transmitted by other plates. When overhauling a room, it is worth laying insulating materials on all surfaces. It is desirable to use multilayer structures.
Noise isolation, which can really increase the comfort of an apartment, is a combination of a rubber mat, mineral wool and a film layer. At the same time between the layers should be a gap of 0.5-1 cm for the free reflection of sounds. In addition, it is necessary to select high-quality materials that do not have to change in 1-2 years.
