The car contributes to increased comfort, since this insulation prevents noise penetration from the outside to the salon. To ensure a car from hitting the sound will not work, but a small and average sound is noise insulation can drown.

Noise insulating processing of any car comes down to applying noise absorbing layers on certain parts of the car body. Such processing can be conventionally divided into three zones - the front of the car, the interior, the rear.

The processing of the face is reduced to the noise insulation of the boobspace and the arches of the front wheels. Rearly insulation is applied on the walls, the floor and the trunk lid on the inside.

The most undergoes noise insulation. It is caused by insulating layers on the floor, the wall bordering the engine compartment, the ceiling and the door. If an auto in the body by type of hatchback, then the noise insulation processing of the cabin is combined with the rear handle.

It is worth noting that automakers do not always pay attention to worthy noise insulation, well, or simply save on it. And if there can be quite high-quality material with good sound-absorbing properties to the floor, then on the doors of cars, often the treatment is very weak, although the sound is penetrating very well through them.

Noise isolation of the car doors with your own hands - the operation is completely executed if you know the sequence of action and correctly select the necessary materials.

If there is noise insulation of doors, the music in the cabin becomes much better

One of the main factors that affect the complexity of the performance is the presence or absence of elements in the doors. If there are no dynamics, then the door will be easier, and the material will spend less.

The presence of speakers in the doors will somewhat complicate work, but the final result of the work on the noise insulation of the doors will lead to an improvement in the sound.

It should be noted that the noise insulation of the doors will lead to another positive factor - due to an increase in the mass of the door due to the applied layers, they will be easier and quiet closed. But it is important here and not overdo it. A large amount of noise insulating layers can lead to an excessive increase in mass, because of which the doors can suit or pull them away.

Necessary materials

To perform work, it will be necessary not so much:

Preparatory work

Next, consider the sequence of actions. First of all, you should remove the door map. It is necessary to do it carefully so as not to damage it, as well as the elements of its attachment. If there are handles for lifting, they need to be removed from the shaft, the door opening handle can not be touched.

If there is factory noise insulation on the door, it will need to be removed from the door, the dynamics will also need to dismantle, if any.

Before you start, you need to remove all items from the car door that can prevent the installation of noise insulation

Any door of the car consists of two walls - the inner, which is closer to the cabin, and external. Often, automakers on the outer wall are applied anti-corrosion processing, which will also have to remove, for which you can use white spirit and vet. At the same time, it is necessary to remove the anti-corrosion processing in order not to damage the walls. After removing the processing, the door will need to dry well.

This preparatory work completed and you can start gluing insulating layers.

Noise insulation of the doors of the car do it yourself

If the door is mounted on the outer wall, in the area of \u200b\u200bits location, you can stick the circle of the anti-slip material, in the future it will have a positive effect on the sound. But the entire surface of the outer wall should not be accumulated by this material, since it absorbs moisture well, which can lead to the emergence of corrosion.

Next, go to the inner wall. To this wall, too, you need to stick a layer of vibration insulation. Moreover, it will take it from two sides. On the inside, the one is closer to the outer wall, the pieces of vibration insulation are pasted, on all available surfaces, but it is important to monitor that in the future they do not interfere with the operation of the door opening mechanism and lifting glass. After stickers, it is better to immediately check their performance, if necessary, you can make lubrication of these mechanisms.

It is necessary to attach the door from the inside

After processing the inside of the wall, it is possible to embark on the outside, the one goes to the cabin. This side can be saved, together with the technological holes. After pasting, you will need to cut holes under the speaker, door opening knobs and lifting glass, as well as when necessary to carry out all the necessary wiring.

Then an insulating layer is glued to the applied layer of vibration insulation. It should cover the surface of the vibration insulating layer, after which it is cut into this layer the necessary holes. At this stage, you will need to check the performance of all the door mechanisms once again, as well as set the speaker if it is attached to the door wall, and not to the map. After the stickers of the noise insulating layer, an almost closed space is formed inside the door between the walls, which will significantly improve the sound of the speaker system.

Further, work is made with the door itself. You will need to stick first vibration insulating material chopped on thin flap. It is better to do it along the contour, as well as stick a few stripes on the inside of the card. If it consists of two parts, they need to cry for both. Applying the strips of this layer will prevent the vibration of the card.

Then the entire surface of the card is covered with anti-slip material, with a small margin at the edges. After that, you can attach a card to the door. But before this, it is better to replace all fasteners to new ones, as well as use self-tapping screws, but only in such places where they will not be noticeable. It is necessary to do this because the old items may not stand the load and the map will go away from the door.
