Why do you need insulation in the apartment
Method of noise reduction in the apartment depends on the type of noise you want to eliminate. All penetrating into the apartment, the noise can be divided into 2 types: vibration (shock) and acoustical (air). Vibration noise is sound waves, which propagate in a solid medium. Many people know from their own experience how it is good sometimes hear the neighbors upstairs drop heavy objects, jump rope, stomp or rearranging furniture. But if anyone in the stairwell, wielding a jackhammer or hammer, the strongest roar on all apartment high-rise building. Here is the impact noise.
The noise level around 40 decibels will not give an opportunity to relax, and the noise of over 85 decibels can lead to mental disorders.
Acoustic noise associated with the propagation of sound vibrations through the air. This type of noise include loud music and voices in the neighboring apartment or room, the hum of passing cars, etc. the Sources of acoustic noise is the uneven joints between the panels, too thin walls, through holes for sockets, etc.
The only thing that can help in the conditions of a multistory building to eliminate noise — the soundproofing of the apartment, which should be comprehensive. Insulation is a decoration of the walls, ceiling and floor sound-absorbing materials. In addition, for integrated sound insulation to the doors and Windows as much as possible absorb the noise. The highest degree of noise isolation you can achieve if you take care of it at the stage of construction of the building, as the degree of noise absorption depends on the thickness and type of material from which made the walls of the house and its interior ceiling.
Integrated sound insulation in the apartment
The quality of the joints of ceilings and thick concrete walls provide a good protection against the penetration of noise. But, unfortunately, the design/construction standard panel houses the insulation factor is not taken into account. To provide comprehensive protection from noise, it is first necessary to make sound insulation of the ceiling, floor and walls using sound-absorbing materials that can be purchased in companies that sell building materials.
In addition, you need to pay taking out the following sources of noise ingress:
- junction boxes and sockets;
- pipes of water supply and heating;
- the joints between the ceiling, walls and floors;
- front door and Windows.
Noise insulation walls in the apartment
The panel houses the partitions and walls often have a small thickness, and so poorly absorb sound. To provide sound insulation of the walls, usually their thickness increase with drywall. The space between him and the wall is filled with porous material: polyurethane foam or mineral cotton wool, preventing the propagation of acoustic oscillations.
The greater the number of layers of sound-absorbing materials, the higher the efficiency noise-proof design.
First of steel profiles mounted skeleton. To eliminate transmission of vibrations from the floor and walls, and clamping profiles need to make a strip of elastic substance, for example rubber. When the frame is prepared, is glued on the wall sound-absorbing material, which completely covers its surface. The thicker the layer of this material, the more effective will be the noise. After that, the frame fasten the drywall sheets.
Insulation ceiling and floor in the apartment
Insulation of the ceiling is very important because most of the inconvenience associated with the noise that produce the neighbors above. Soundproofing ceiling is on the same principle as the insulation of the walls. First, the profile frame is assembled, you do not need to forget about pads of rubber in the places of its attachment.
After that, all its internal space is filled with any absorbent substance: a glass Mat, a foam or a special sound insulating slabs made of basalt or mineral wool. Such plates at their small thickness have excellent absorbing effect. After their installation, the ceiling height in your apartment will decrease only slightly.
If between tiling and overlapping, there is no intermediate layer, the noise from downstairs will constantly enter your apartment. At the same time, your neighbors can hear everything that's going on, until the sound of moving chairs and even steps. The issue of soundproofing the floor is solved by using special sound-absorbing material having a small thickness.
This material is made of special paper, fiberglass, foamed polymer, or other synthetic substances. In the repair process, depending on the kind of material the sound-absorbing layer, such material can be placed or directly under the screed, or under the laminate. This type of noise isolation perfectly dampens vibration and absorbs impact. When laying noise-isolating layer over the top of it is placed the film for waterproofing.
Insulation mounting boxes and outlets
In reinforced concrete slabs prefabricated houses are through holes for electrical installations. In such cases outlet be the conductor of the noise between adjacent apartments. To provide a soundproofing outlet, initially it should be shut down. After disassembling the socket, it has to come out, and then put in the hole of the washer (gasket) of the dense sound-absorbing material is compressed mineral wool, asbestos cloth or thick cardboard. After that, it should be carefully cement using gypsum mixture.
Working with sockets requires knowledge of electricity, and therefore it is better to trust the professionals.
Junction boxes are typically located near the ceiling in the middle of the wall. In some cases they can be hidden under the Wallpaper. Soundproofing boxes are performed by the same principle as the insulation of outlets. Need to get the plastic plug, and then install and cement the puck out of the noise insulation material. Before carrying out these works is necessary to ensure that the network does not have voltage.
Insulation of pipes Central heating
In accordance with the building regulations, risers are laid through the ceiling between floors using special liners that prevent the spread of noise. The sleeve is a piece of pipe of larger diameter, mounted in the ceiling. The gap between the pipe and the sleeve shall be filled with mineral wool or other sound absorbing material.
However, builders often cement risers without the use of casings. Over time, the cement is destroyed, the gap between the wall and the pipe increases, and sound from the apartment above, goes through the slot. To provide sound insulation of the riser, you need to clean around the pipe concrete to a depth of 10 cm Vacant pipe should be wrapped with mineral wool or fiberglass, and then again to cement. The resulting surplus of absorbent material are cut, and place around the pipe putty.
Insulation of joints, Windows and doors
In the process of operation panel buildings between floors and walls, and also along the joints, often there are cracks through which from the neighboring apartments can penetrate the noise. Causes these cracks can be different deformation buildings, as well as panel poorly adjusted to each other. To ensure sound insulation of joints necessary with a screwdriver or chisel to expand the crack, gently cleaned them, primed, paint over putty. When the latter dries, the surface of the joints need to be covered with acrylic sealant.
To eliminate the gap between the floor and the wall, fill it with silicone sealant, then seal with a special tape and install the baseboard in place.
From the noise from the entrance or from the street, the apartment needs to protect doors and Windows. To do the noise insulation of Windows, it is best to install special soundproof double-glazed Windows. They use a technology triple glazing, which allows to minimize the penetration of noise in the apartment. The gap between the wall and the glass is sealed thoroughly.
The heavier and thicker the door the less sound it will pass in the flat. Additionally, the doorway seal around the perimeter with a special rubber gaskets. This certainly is the threshold, and the space between the doorway and the door frame is sealed with cement mortar. The door should fit snugly enough to the box.
To effectively increase the sound insulation in the apartment, remember that the best result is possible when an integrated approach. It is necessary to use only quality and tested materials. When the apartment is provided with a good level of sound insulation, and life becomes much nicer: alarm in the courtyard and noisy neighbors.
