VAZ 2107 do-it-yourself car soundproofing

The factory sound insulation of the VAZ 2107 is not far removed from the FIAT of the 60s, which became the prototype of the “penny”. Noises in the car make it difficult to talk and enjoy music while driving. The comfort of the “Seven” can be significantly improved by reducing the noise of the external environment and vehicle components, which is heard in the cabin while driving.

Purpose of sound insulation

Additional sound insulation reduces the noise of the engine, suspension, chassis and reduces vibrations that occur during operation of car components. Thanks to this, in the interior of the “Seven”:

• you can talk without raising your voice;
• you can enjoy music without noise interference;
• The overall noise level is reduced, which improves driver concentration and response.

Consequently, sound insulation of the VAZ 2107 provides additional safety and reduces the harmful effects of noise on the nervous system.

Is sound insulation really necessary?

This question can only be asked by owners of foreign cars who have never been to a VAZ-2107 showroom. Having driven once behind the wheel or as a passenger in a VAZ Seven, you immediately understand that sound insulation is necessary. In the cabin you can clearly hear the sound of the engine, gearbox, noise from the wheels and other sounds outside the car.

Those who like to listen to high-quality sound in the VAZ-2107, which lacks sound insulation, will be greatly disappointed. Buying expensive musical acoustics will not help. As long as there is no good sound insulation in the cabin, the music from the speakers will be greatly distorted.

High-quality sound insulation brings joy not only to the ears of the owners of the 2107 model. During the cold season, the car will be warmer and the interior will warm up faster. In hot weather, with proper treatment, the interior of the car will be cooler and more comfortable. Many advantages of the complete sound insulation of 2107 can only be appreciated in person. All questions about necessity will then disappear by themselves.

Features of the use of soundproofing materials

For sound insulation, you should use specialized materials intended for use in a car. Using building sound insulation or, for example, sweatshirts will not give the desired effect and can cause harm. For example, the fire safety of the interior will deteriorate or the material will begin to absorb moisture, leading to corrosion of body elements.

Particular problems are caused by filling body voids with polyurethane foam. This homemade method helps to achieve a significant reduction in noise in the cabin, eliminating vibrations. However, polyurethane foam perfectly absorbs moisture, forming a humid environment in the sills and other cavities of the body. Accordingly, the metal quickly rots and body parts require unscheduled replacement.

The order and method of placing soundproofing materials is of great importance. Violation of technology will not allow you to get the desired result, regardless of the quality of the materials used. They are stacked in the following order:

• The first layer is a material that absorbs vibration from the metal elements of the body.
• The second layer is a sound-reflecting and sound-absorbing material. The first is located outside in the area of ​​the wheel arches and engine. The sound absorber is used inside the cabin.
• A third layer of sound insulation - anti-creaking material - is placed under the trim elements and the dashboard.
• The fourth layer can be a decorative coating, if necessary. It gives a complete and aesthetic appearance to the completed work.

The first defense is doors

Despite the fact that the most unpleasant sound enters the cabin through the engine partition and through the floor, it is best to start work from the doors. This is much easier than immediately disassembling the interior. It will take less time, and you will gain a lot of experience. The following stages will therefore go faster and better.

The first place to start is by removing the casing. Having reached the iron base, do a visual inspection for corrosion. If there is one, it is cleaned and treated with a rust converter and anticorrosive. Be sure to give it time to dry. Only after this, using a hairdryer, the vibroplast is heated and pressed against the surface with a roller. The next layer is the sound insulation of the VAZ-2107 doors. And last but not least, if desired, a layer of sound insulation.

Car doors have many moving elements that can cause squeaking. Therefore, the use of anti-squeak materials such as madeline or bitoplast is relevant here. The first has a small thickness of about 2 mm, and the second is somewhat similar to thin foam rubber impregnated with a special composition.

Required Tools

To install soundproofing you will need the following tools:

• rags;
• solvent;
• set of screwdrivers and keys;
• construction hair dryer;
• roller for rolling sound insulation sheets;
• cotton mittens;
• cardboard for patterns;
• spray bottle for applying liquid sound insulation to the bottom;
• soundproofing materials.

Soundproofing a VAZ 2107 is a labor-intensive job and will take a whole day to complete. It is better to carry out the work in the garage so as not to depend on weather conditions and protect surfaces from dust and contamination.

Selecting material for work

Soundproofing a VAZ 2107 is a simple process, but quite expensive both in terms of finances and time. In order not to waste time, you can entrust car noise reduction to professionals, but you will have to pay decent money for the work. The best option is to carry out the procedure yourself, for which you will need to stock up on basic materials for the work, as well as tools and patience.

Soundproofing materials today are replete with variety. They differ not only in cost and appearance, but also in the quality parameters of suppressing external noise and vibration. Some are designed to reduce vibration, while others are designed to reduce noise. The best option for noise reduction of a VAZ 2107 car is products from brands such as: StandardPlast (STP), Shumoff and others. In this article we will consider the process of gluing Shumka using STP materials.

The advantage of materials of these brands is that they meet all noise insulation requirements and have a relatively low cost. The materials can be either universal, but you will need to cut the product into pieces, or special ones for each brand of car. This is very convenient when you don’t want to cut out the noise insulation of the hood or doors into pieces. But such options are more expensive than universal ones. Having purchased the basic material, you can begin to work. Let us consider in order the features of noise reduction of the main components of the VAZ 2107 car.

Hood

It is recommended to glue a ready-made set of Shumkas about 3 cm thick with a foil coating onto the hood of the “Seven”. It's easy to find at the car market. Why is it necessary to tape the hood? This is done, first of all, to keep the engine warm and quickly warm it up in winter, and to some extent it reduces the noise level coming from a running engine. The hood is glued between the ribs, so you will need to aim carefully while working.

Soundproofing the hood of the VAZ 2107 is based on the following procedures:

• Using a degreaser, such as white spirit, you need to degrease the surface on which the material will be glued. Surfaces that are heavily soiled or oily should be cleaned first.
• In the cold season, it is necessary to warm up the adhesive side of the product using a hair dryer. This procedure is mandatory, since the effectiveness of adhesion depends on the quality of heating.
• After warming up the sound insulation sheet, you should remove the protective layer from the adhesive side, and then glue the product to the hood from the inside.
• For high-quality gluing, you will need to use a roller or press well with your hands.

Preparatory work

First you need to decide on the procedure for soundproofing parts of the car (trunk, interior, hood, etc.). This is followed by:

• purchase the necessary materials (they can be purchased in sets for each part of the machine or per meter, having previously calculated the required quantity);
• prepare a set of tools;
• make cardboard patterns (if the materials are purchased by the meter and not in ready-made kits);
• disassemble the insulated area down to the metal, removing the trim elements, dashboard, and other parts that impede work;
• wash the surface thoroughly and dry;
• clean and treat areas of corrosion;
• degrease with solvent.

Sound insulation of the trunk and hood of the VAZ 2107

The opinion that sound insulation of the engine compartment is necessary only for the comfort of others is false. It performs several important functions:

• reduces metal vibration;
• muffles the engine sound penetrating into the cabin;
• improves thermal insulation and prevents the engine from cooling quickly in winter.

Soundproofing the trunk is important for the following reasons:

• improves the sound of the subwoofer (if equipped);
• dampens external sounds penetrating into the cabin;
• reduces vibration noise during operation of the acoustic system and movement of the machine;

In the engine compartment, sound insulation should begin with the engine compartment panel. To increase the elasticity of the “vibroplast”, it must be heated with a construction hairdryer before laying. After laying it, the surface must be rolled with a roller to remove air bubbles, which reduce the effectiveness of the insulation and can cause corrosion of the body. “Splen” must be glued on top of the “vibroplast”.

The hood and trunk lids are insulated in the same way, with the difference that the “vibroplast” is not laid over the entire area, but only between the stiffening ribs.

The wheel arches in the trunk require additional sound insulation. For this, an additional layer of sound insulation is used.

Make sound insulation for VAZ 2104, 2105, 2106 and 2107 in Moscow

Installing sound insulation is a complex and painstaking process. How is sound insulation installed on classic cars VAZ 2104, 2105, 2106 and 2107? After a preliminary inspection of the car, we draw up a detailed list of work. Then the process of disassembling the machine begins, a very responsible and important process. For example, we carefully pack each interior element in protective film. Then the cleaning stage begins, degreasing the surfaces. Only then does the process of installing sound insulation begin. After completing the painstaking work of multi-layer sizing of insulation, the car is assembled and cleaned. Photo materials are attached to the reporting documents so that you can see how we worked on your VAZ car.

Sound insulation of VAZ 2107 doors

The vibration and noise insulation coating on the doors improves the sound of the built-in speakers, eliminating resonance, and prevents street noise from penetrating into the car. The isolation procedure is as follows:

• stick “vibroplast” onto the door panels;
• stick the second layer “Accent”;
• wrap the rods with “Madeline” to eliminate squeaks;
• cover the outer layer of the doors with “vibroplast”;
• seal the technological holes with “bitoplast” or foil;
• glue the door trim on the inside with “Accent” to improve sound absorption and fit of the part.

Doors

Sound insulation on the doors of VAZ 2107 cars is necessary in order to reduce the level of noise coming from outside, as well as improve the sound quality of the audio system.

Sound insulation of VAZ 2107 doors

The insulation kit contains only vibration damping material, but it would not be amiss to treat the surfaces with noise absorbers.

1. The first layer of processing is carried out through technological holes. Vibroplast Silver has proven itself excellent here.
2. First, treat the areas behind the speakers.
3. The second layer is Splen 4 millimeters thick.
4. Now tape the outside of the doors under the cards. Use an audiophile. It is necessary to completely seal the technological holes, which will seal the volume of the doors where the speaker is located.
5. Applying a vibration filter will increase the rigidity of the door, which will make the acoustics sound better.
6. The outer sides are covered with vibroplast, and a layer of Spleen is applied on top for sound insulation.
7. It would be a good idea to treat the door cards with anti-creak. Thick Bitoplast is suitable here.
8. Crickets inside the doors will also make themselves felt over time, so immediately additionally cover the rods and handles with Madeleine.
9. Don't use too thick a layer of insulation, otherwise you simply won't be able to secure the cards back together properly.

Soundproofing of the VAZ 2107 interior

Before soundproofing the interior, you should make sure that components and assemblies that can create additional noise are in good working order. Sound insulation of the VAZ 2107 interior is carried out so that vibration and sound insulation materials do not cover the mounting holes.

The procedure for soundproofing the interior:

remove the seats;

• remove the dashboard;
• remove floor and ceiling coverings;
• wash surfaces;
• clean and treat corrosion areas;
• degrease with solvent;
• stick a layer of “vibroplast” on the roof, then “Accent”;

Tip: you need to glue the roof with an assistant, who helps warm up the material and holds it while rolling with a roller.

• stick on the arches, in addition to the “vibroplast”, a double layer of “Accent”;
• lay “Bimast Super” on the floor;
• cover the floor with “Accent”;
• stick “Accent” on the inside of the dashboard;
• cover the body partition under the dashboard with “vibroplast”;
• stick “Madeline” in places where the dashboard touches the body to prevent squeaks.

Floor

If you examine the standard sound insulation on the floor of a VAZ 2107, you will find a bitumen-based vibration damper no more than 3 millimeters thick, and a standard noise insulation of 7-10 millimeters. Moreover, more often than not, they were not laid very well, which affected the comfort of the driver and passengers.

Soundproofing the floor on a VAZ 2107

So that you are not bothered by all the pebbles that hit the bottom when moving, you will need to perform the noise yourself.

1. This area opens up enormous opportunities for creativity and the use of all kinds of materials. Some use sheet insulators, others use mastics based on rubber and bitumen.
2. The advice of experts is to use Bimast Bomb as a vibration damper, and make Shumka from Spleen.
3. Pay special attention to the processing of the inner wheel arches. They will require 2-3 layers of the thickest insulating material.
4. Thick sheets of Splen are not very convenient to lay, so it is better to use thin material and apply it in 2 layers, without leaving gaps.

Sound insulation of the bottom of the VAZ 2107

External underbody sound insulation reduces tire noise and rock clatter while driving. For this purpose, you should use liquid sound insulation, which is applied with a spray bottle. After drying, it is foamed rubber and performs anti-corrosion and soundproofing functions.

Thanks to the spray application, such sound insulation can be easily and quickly applied in hard-to-reach places. Its weight is significantly lower than that of sheet material, vibration and sound insulation properties are no worse, and the price is only slightly higher.

After applying the soundproofing coating, it is necessary to carefully assemble the parts. Loose tightening of threaded connections, broken clips and other assembly defects can neutralize all efforts to reduce the noise of the “seven”.

In conclusion

Sound insulation of the VAZ 2107, as well as in other domestically produced cars, the so-called “classics”, is usually absent, or leaves one to expect better. The big drawback of all Russian cars is the loud noise inside the cabin when driving. In the domestic automobile industry, practically no measures are being taken to improve the sound insulation of products, since this significantly increases the cost; for the same reason, today even in foreign cars you rarely see high-quality Shumka, let alone the 2107, in which sound insulation becomes the business of its owner.

Briefly about sound insulation
The VAZ 2107 model is called in dealerships one of the best domestically produced cars, but it also suffers from a similar flaw:
- When driving, the “Seven” is noisy and rumbles so loudly that you can only talk in the cabin if you raise your voice too much (in fact, up to scream); — In addition, as scientists have already proven, increased noise affects the nerves and the functioning of the heart, so it is harmful to human health; — That is why many owners, in order to eliminate unnecessary noise, carry out noise treatment in the car interior with their own hands; — The process of isolating noise in a car is not complicated, but it is time-consuming and financial; — If you don’t have any problems with finances, then it’s easier for you to take the car to a service station, where they will perform a full or partial noise of your choice; — The price of work and materials will of course be higher, but you can spend your time on something else; — If you do the work yourself, you will get huge monetary savings; — Sound insulation of the VAZ 2107 is divided into complete and partial; — Partial “shumka” gives you the opportunity to gradually process the interior and body of the car; - At the same time, there is no need for a large amount of money at once and you can get good at the simplest areas, for the next finishing of more difficult areas of the car; — First of all, it will be necessary to process the wheel arches on the outside and the bottom of the car; — Then move on to the hood and trunk; — Then the floor in the cabin, the doors (see Soundproofing the doors - it’s not difficult), the instrument panel and ceiling, the engine bulkhead can be combined with the hood; — The maximum effect is obtained with complete processing and use of specialized materials; — Today, car owners sometimes use unimaginable components (batting, linoleum, mineral wool) as soundproofing materials, which are not at all suitable for car treatment, since their sound-absorbing properties are much lower than those of automotive materials; — We recommend that you use only special noise-insulating automotive materials that reliably protect your car and do not emit harmful substances and dust; — The most popular products today are StandardPlast and Shumoff; — The materials from these manufacturers meet all the requirements that apply to this type of product and the price is acceptable; — In order not to “bother” with cutting out templates and adjusting the “noise” to the gluing places, you can purchase ready-made kits for processing the hood, trunk, and doors of a VAZ 2107 at any car market; - Now in the VAZ 2107, sound insulation of the trunk, hood and doors will only require you to correctly glue the materials to the internal space of the elements being processed; — As always, first clean and degrease the surfaces to be glued with a solvent; — Now let’s take a closer look at the entire process of processing individual parts of the VAZ 2107.
