Sound insulation: installed on VAZ 2114

Do-it-yourself noise insulation of VAZ 2114 according to instructions

How to make sound insulation in a VAZ 2114

Do-it-yourself soundproofing of the VAZ 2114 has the most important goal - to reduce the level of audibility of extraneous sounds in the car interior. Noise comes from the power unit, the wind outside when moving quickly, and other sources.

If you know how to make noise insulation for a VAZ 2114 yourself, you can significantly reduce the noise level and save a lot of money at the same time, since services of this kind in service stations are not cheap.

Do-it-yourself step-by-step soundproofing of a VAZ-2114

VAZ-2114 has a high noise threshold.
While the vehicle is moving, the driver and passengers are forced to hear extraneous sounds. The sources of noise can be the power unit and even the wind. It’s difficult to call such a ride comfortable, so owners of domestic cars sooner or later think about how to soundproof a VAZ-2114 with their own hands. Car maintenance yourself saves a lot of time and money. With a little experience and knowledge in repairing the VAZ-2114, you will always feel confident on Russian highways. Moreover, domestic cars seem to be created for studying the internal structure of the structure - mechanics allow you to independently eliminate almost all problems of the components.

General information about the process

The initial one is provided by the manufacturer at the stage of assembling the machine. But gradually, due to temperature changes, any material loses its beneficial properties.

Before you start carrying out the “Shumka” on your own, it is recommended to dismantle the seats, door trims, mats and free the car from the old standard insulation.

Note. Only by carrying out a complete and thorough soundproofing procedure can one hope for a significant reduction in noise from the outside. Only in this case will the cabin be perfectly quiet and comfortable.

It is especially important to treat doors, as they often become the main installation location for speakers. It is clear that this place should be well protected not only from noise penetration, but also from plastic vibrations and other negative phenomena.

Along with sound insulation, the interior will also receive high-quality insulation. In Russian conditions this is extremely important. To achieve this effect, you need to combine vibration and sound insulation.

Soundproofing for VAZ 2114

“Shumka” carried out on a VAZ 2114 is often called tuning. This is true, because a real modernization of the car is being carried out. Operational parameters are increased and comfortable conditions are created when the vehicle is moving.

The driver is no longer oppressed by engine noise, his nervous system is not irritated by the strumming and vibration of plastic elements. All this cannot but have a positive impact on overall driving safety.

As mentioned above, the standard “Shumka” will not be of good quality; relying on it is the last thing. The process of carrying out “Shumka” on cars with high mileage is especially relevant. In general, such cars are very difficult to drive, since the noise penetrates everywhere, interferes with the normal operation of the acoustics, creates complete discomfort, and the trip turns into a very tedious task.

On sale today you can find a sufficient amount of high-quality materials for carrying out “Shumka”. There are a lot of them and making the right choice can sometimes be extremely difficult. One of the main indicators of a good material is not only the ability to absorb sounds, but also to be light in weight (details about materials in the table below).

Note. If the material itself is heavy, making noise will be difficult. As a rule, good and proper insulation involves laying several layers of material, a kind of sandwich consisting of layers of vibration and noise absorbers. Heavy materials will create excess weight that is dangerous for the car and its body, which will inevitably affect fuel consumption and the overall dynamics of the car.

Among other things, you also need to lay out materials skillfully. The fact is that if you don’t pay attention to this, the materials will simply turn into a time bomb for the metal component of the car.

Poorly laid material creates gaps through which air, moisture, etc. will penetrate. And all this will inevitably lead to the appearance of the most terrible enemy of the body - corrosion.

Correct installation of the material always means following the instructions in a step-by-step sequence, using the right tools, using a hair dryer and much more.

In some cases, especially when carrying out the noise yourself, partial sound insulation is also appropriate. In this case, the target is the most noise-producing parts of the machine. Definitely the doors, then the trunk, the rear parcel shelf, and so on.

It is important, when working on your own, not to damage the upholstery. Unfortunately, this often happens due to the inept actions of the car owner who is carrying out such an operation for the first time. In general, conducting a “Shumka” is a painstaking and lengthy process, but it’s worth it.

Before carrying out soundproofing, it is recommended to carry out a partial or complete inspection of the machine. The causes of all vibrating and knocking sounds produced by suspension elements or other vehicle components must be eliminated. They may be loose or need to be replaced. The body and its parts must also be checked.

Algorithm for carrying out an operation to “shumka” a VAZ 2114 car

To isolate the interior from excess noise, you need to carry out soundproofing by following these step-by-step instructions:

1. First, disassemble the car, removing those parts that make noise when driving. These could be mudguards, arches, fenders, etc. It is advisable to cover them from the inside with some kind of vibration-damping material;
2. The seats will also need to be removed if the interior is fully soundproofed;

• Cover the floor of the car with a vibration damper and roll it in with a special tool.

Advice. To ensure that materials adhere better to metal or plastic, it is recommended to carry out work in a dry and warm room. In a damp room, it is better to preheat the foil with a special hair dryer, and only then roll it onto the surfaces of the body.

• The next material, as a rule, is Spleen. It has a sticky base, lays on surfaces easily, and perfectly cuts out excess noise penetrating from the outside;

To install materials in the trunk, the lid is removed in advance, all screws and bolts are unscrewed.

Note. In general, disassembling the luggage compartment involves a separate operation. Here you will need to prepare everything thoroughly, disassemble the compartment down to the bare metal surface, pull out all the wires going into this area. As for laying materials, only clean and dry surfaces should be processed. After the material has been laid, you will need to put the wiring back in and close all the extra holes.

• Door treatment (see Soundproofing VAZ 2114 doors can be easily done independently) is practically the most important procedure in terms of increasing the so-called “acoustic” properties of the interior. It is recommended to insulate these parts of the car with a good polyurethane-based material. The front doors of the VAZ model, which are entrusted with the role of a stand for acoustic speakers, are recommended to be rolled in two layers.

Note. In fact, the “noise” of the door also involves the initial disassembly of the upholstery, gluing both sides and the card. Door technological openings are closed only on one of the edges.

• The roof of the VAZ 2114 is also treated. In order to fully carry out the “noise” of the car ceiling, you will need to remove everything, from the mirrors to the upholstery;

• No less valuable in terms of protection from the penetration of external noise and sounds of the internal combustion engine is the hood. You also need to be able to properly process it (see Soundproofing the hood of a VAZ 2114: is it necessary or not).

Trunk

When the car is moving, noise from the muffler and the road is transmitted through the trunk floor into the cabin. Therefore, it will not be superfluous to soundproof the trunk of a VAZ 2114. The design feature of this model is that the luggage compartment is located directly inside the cabin.

The whole process can be divided into several stages:

• Pasting the trim and luggage compartment lid;
• Processing of metal components;
• Application of bitoplast;
• Assembly.

Now let's look at each stage in more detail:

1. Remove all trunk trim elements to remove dust, dirt, and grease from the internal surfaces.
2. Be sure to treat the surfaces with special anti-corrosion compounds and white spirit.
3. Small elements of soundproofing materials should be glued to the casing. It is not recommended to use too much, as this will noticeably make the structure heavier.
4. The lining of the entire trunk, including the area for the spare tire and the lid, is treated with sound-absorbing materials. Experts advise using Accent or Bitoplast. But in the spare tire area, use Splen.
5. Now let's move on to the metal parts of the body. They need to be cleaned and then covered with sound-absorbing materials. Gold is well suited for the VAZ 2114 because it weighs a little but effectively copes with its task. Try to prevent air bubbles from appearing between the sound insulation material and the body.
6. Next comes Bitoplast. It plays the role of a noise-absorbing material. It treats the entire surface of the trunk, excluding the spare wheel compartment. There, as you remember, Splen is used.
7. You can then use a layer of Splen around the entire perimeter, applying it on top of the sound absorption material. In this case, Splen will play the role of a thermal insulation coating. Please note that you should not install a lot of noise, since you simply may not be able to install the casing back.
8. The process is completed by assembling the entire structure. This is not difficult to do, just follow the instruction manual, try to work carefully with all fasteners.

Useful tips

Today, many owners of the VAZ 2114 install new acoustics in the car, more powerful and productive. They buy an expensive subwoofer (see 1000-watt subwoofer and a review of the best models), a powerful amplifier (see The best amplifier for a subwoofer and how to choose it) and a lot of other useful things that significantly increase the level and quality of sound. But imagine their disappointment when all the money spent turns out to be thrown down the drain, since the sound still leaves much to be desired.

It turns out that the whole point is insufficient insulation of the car body panels, through which noise penetrates from the outside. It’s no longer possible to enjoy clear sound: rattles, vibrations, knocks - all this degrades the quality.

As mentioned above, car doors are very important in this regard.

Here's what you need to focus on:

• They must be insulated on both sides, although excessive zeal should not be shown either. Heavy doors mean they may sag over time;

• In addition, we must take into account the fact that the doors of the VAZ 2114 are often covered with cellophane. The latter makes unpleasant sounds and creaks in the cold season in the frost;
• It is advisable to lay materials on the door in large pieces (as much as possible). The materials used should not be visible beyond the edges of the sheathing. It’s not difficult to learn how to carry out “Shumka” with your own hands. Step-by-step instructions, photos, materials, and videos will help in this matter. The factory standard insulation must be completely stripped off so that new materials can be installed efficiently.

How to assemble a VAZ 2114 panel

It is important to know that VAZ installs very fragile fasteners on its cars. Therefore, they are very easy to break, which means that when disconnecting the shield from them, you need to be doubly careful. Today we’ll talk about how to remove and disassemble the instrument panel on a VAZ -2114, and what should be taken into account during the work.

Where to begin

1. We take a positive screwdriver and carefully remove the three screws that secure the left screen. If you have a tool with a short tip, it is better to use it, it will be more convenient.
2. We remove the lower part of the lining from the mounting on the body.
3. We do the same with the screen on the right side. The only difference is that it is fixed with 5 screws. While working, carefully hold the pad with your hand.

Now that all the fasteners have been removed, you can remove the screen. But be careful that it doesn't get caught on the wires underneath it. Otherwise, you may simply break the cables.

Next, you should disconnect the ground from the battery. This is done by disconnecting the pads. If a radio is installed in the car, it must be disconnected from the wiring. If you do not have any audio devices installed, you can simply remove the wires (they are closed with a plug). Then the cigarette lighter and the socket that illuminates the ashtray are turned off.

So, the first stage of work has been completed. You can proceed to the next steps.
