VAZ-2107: noise isolation by one's own hands. Detailed description of the work package

The car VAZ-2107 is an excellent classic product of the Togliatti automobile plant of past years. Despite the fact that it was withdrawn from production, 7-ka remains on the wheels of many drivers. Inexpensive and easy to maintain, the device is well suited for acquaintance with motor transport as the first machine for learning. But there is a significant disadvantage. Like any classics of Russian production, the 2107 has a poor noise isolation.

What is needed for noise isolation, is it important and how it works? You can find answers to these and other questions in this article. We will consider the sequence of actions for independent work by one's own hands, the necessary tools and materials. And if it is necessary to carry out such procedure as noise insulation of VAZ-2107, is it worthwhile to undertake altogether or better to give the car to a specialized maintenance center?

Is it necessary to use noise insulation?

This question can ask unless the owners of foreign cars, which have never been in the salon VAZ-2107. Once driving around behind the wheel or as a passenger of the VAZ-7, you immediately realize that noise insulation is necessary. In the cabin, the sound of the engine, boxes, noise from the wheels and other sounds outside the car's saloon are clearly heard.

Lovers listen to a quality sound in the VAZ-2107, noise insulation in which there is no, will suffer a strong disappointment. Do not buy expensive music acoustics. While in the cabin there is no good sound insulation, the music from the speakers will be greatly distorted.

High-quality noise insulation brings joy not only to the ears of the owners of the 2107 model. In the cold season, the car will be warmer, and the cabin will warm up more quickly. In hot weather, if the salon is properly processed, it will be cooler and more comfortable in the car. Many of the advantages of complete noise insulation 2107 can only be estimated live. All the questions about the need after this will disappear by themselves.

Easy choice

After the decision to conduct noise isolation is taken, it remains to decide where it can be done. The options are actually a bit:

1) specialized service station;

2) a private garage;

3) own hands.

Make a choice as to where to make noise isolation VAZ-2107 will have each individually. Consider the pros and cons of each option. In a specialized service there will be the biggest price tag for work, but a guarantee is possible if something is wrong. In addition, the most skilled work is possible there. In a private service it is usually much cheaper, but no guarantee. At the same time in both cases it would be good to know if there is a specialist who makes high-quality noise insulation. Ideally, it would be nice to ride a previously made car for evaluation.

Sound insulation by one's own hands

So, there remains the option - to do everything yourself. Is it possible? In fact, everything is possible. But if there is no experience of owning a screwdriver and wrenches, then this option will not work. For any man, the noise insulation of the VAZ-2107 is quite feasible. The whole complexity of the procedure is not in the process itself, but in disassembling and assembling the interiors of the car. After all, you need to get to the native noise insulation, and better to bare iron.

There are several positive features of the work with their own hands:

• The experience gained will not go anywhere and you do not have to pay for it;
• A good opportunity to learn your VAZ-2107 closer;
• There is no time limit - you can work slowly and accurately;
• Saving of material resources;
• In the end, you can get a comfortable VAZ-2107, noise insulation of which at the proper level, an excellent deal.

Features of the process of noise insulation

In order to produce high-quality noise insulation, it is first of all necessary to understand where the noise comes from, where it is larger and what its nature is. It is known that the main sound comes from the running motor and the exhaust system. Hence - the conclusion: as much as possible to isolate the floor and the front motor partition.

Noise, which can reach from the street, is eliminated by noise insulation of doors and roof. Do not forget about the luggage compartment. Noise from the trunk can irritate very much. As a result, it turns out that it is best to soundproof the entire interior completely. This process is also called complete noise insulation. While partial designate the noise insulation of a part of the cabin, for example, only the floor.

To understand the processes, it is easiest to turn to physics. After all, both sound and vibration have such a parameter as the frequency of oscillations. And if the vibration is usually low-frequency, then the sound is vice versa. Therefore, it is more difficult to isolate and absorb. Hence the importance of the thickness of the noise insulation materials.

First steps

Noise isolation VAZ-2107 own - an interesting and exciting process for fans dig deeper into their cars. If the work is for the first time, it is necessary to prepare for it. The simplest option is to learn from a master who has long been involved in such activities.

Information can also be found in the technical documentation printed and in the electronic version. Having thoroughly prepared, you can go for the chosen material and prepare tools. Sometimes a building hair dryer is required to speed up the process. With its help, the noise insulation material warms up and becomes more plastic. This allows you to squeeze it as tight as possible to the metal base. To smooth the coatings, a hard roller will be very convenient.

Materials used

Factory noise insulation VAZ-2107 consists of two layers: anti-vibration and actually noise-proof, often of the simplest quality. For good quality of work, these materials can be replaced with improved ones. It is also possible, in addition to these two layers, to add soundproof and anti-scratch.

The very first layer protects the interior from vibrations. The reason for them may be different, but most often it is the vibration of the engine transmitted through the supports on the body, as well as the vibration of the gearbox. The worse the cushions of the power unit and the gearbox work, the more tangible it will be. The material for protection against vibration most often consists of two layers: a mastic base and a foil. Among the ready-made variants one can note "Vibroplast" and "Bimast".

As to concrete noise insulation, it is known in shops as "noise". Physically it is a porous material such as foamed polyurethane or thick felt.

As a soundproof layer necessary for the reflection of sound, material that looks like vibro-isolation is used. But on the properties he is different. As the famous brands can be used "Splen". In addition to sound insulation, this material has high thermal insulation properties.

Modern "noises" are very convenient for their adhesive layer. Thanks to him, the installation of coatings is quick and qualitative. Many materials for noise insulation are applied universally - both for cars and for the walls of a residential house.

First defense - doors

Despite the fact that the most unpleasant sound penetrates into the interior through the engine partition and across the floor, it's best to start work from the doors. This is much easier than disassembling the salon immediately. Time will take less, and experience will turn out to be great. The next steps will therefore go faster and better.

First of all, it's worth it to remove the cladding. When they reach the iron base, they make a visual inspection for corrosion. If this is available, the rust converter and the anticorrection are cleaned and processed. Must give time to dry. Only after this, using a hair dryer, the vibrating plate is heated and pressed against the surface by the roller. The next layer is glued to the noise insulation of VAZ-2107 doors . And last but not least, if there is a desire - a layer of soundproofing.

The doors of the car in its composition have many moving elements, which can cause squeaking. Therefore, it is important to use such anti-scratch materials as madelin or bitoplast. The first has a small thickness of about 2 mm, and the second is somewhat like a thin foam, impregnated with a special composition.

Features of sound insulation of doors

Of the important features, it should be noted:

1. It is enough to cover with a vibration isolation material only half the area of the protected surface. It has been experimentally established that the vibrations are equally well extinguished starting at half the area.

2. Noise insulation coating will work the better, the thicker its layer.

3. Increasing the layers of noise insulation, do not forget about increasing the weight of the door, so as not to change the loop later.

Sound insulation of the engine compartment

The partition of the engine compartment has a very small surface area. But the time taken to cover it is usually the greatest. And this is connected, of course, with the amount of disassembly work that needs to be done until the desired surface appears.

A good instruction for removing the dashboard can be found in the resources for repair and replacement. After the application of labor, patience and time, the partition of the engine compartment will appear to perform noise insulation work on it. The order and procedure of sizing by materials are similar to noise insulation of doors. Plus the septum is that for it there is no restriction on the weight, and hence the number of layers. It is important to remember that the layers of noise and sound insulation must be glued without gaps, in contrast to the vibroplast. The sound has a higher frequency than the vibration, so a small hole will be enough to penetrate the interior.

Protection of floor and wings

Noise isolation of the floor VAZ-2107 occurs in accordance with the general algorithm, worked on the door panels:

• Give access to the surface by removing all the interfering elements;
• Remove factory coatings;
• Treat the bottom with anticorruption;
• To lay a layer of vibration isolation;
• Lay a layer or layers of a silencer;
• Fix the soundproofing layer;
• Reassemble in reverse order.

At this stage, there are practically no difficulties, there are no such jobs as panel removal. The most difficult thing is to remove the seats - their weight is the heaviest of what is in the cabin. Again, depending on what to compare. From the nuances it should be noted that the VAZ-2107, the noise insulation of which was carried out as much as possible, will be limited during the pedals. Under them you have to make a cutout for comfortable driving.

Roof Sound Insulation

From the first time it may seem that it is easier to soundproof the roof of the car. There are no hinged elements here, as on the floor, and there are no difficulties with removing the dashboard as in front. The flat surface of the roof is deceptive. In fact, there are many nuances for the accurate removal of native upholstery and coverings.

After the bare iron appears, a well-developed procedure for surface treatment and application of protective coatings will not be particularly difficult. As a result, a truly comfortable VAZ-2107, noise insulation of which is made by own hands, will bring a lot of pleasant sensations. With the protection of the roof should not be "brutal." The absence of noise during the rain is good, but the presence of layers of noise insulation increases the weight of the car, slightly shifting its center of gravity.

Loud boot VAZ-2107

The car's roof rack also requires noise insulation materials. If you produce protection, then make it maximum. In addition, it is in the trunk most often transported a diverse small cargo, which is particularly noisy when traveling.

Noise isolation of the luggage compartment VAZ-2107 - the procedure is quite simple. Easier, probably, only to process a cowl. But the work here is also enough. There are few flat surfaces like on the roof, so you will still have to try.

Noise isolation of the hood

Good noise insulation of the VAZ-2107 hood is quite a simple matter. There is enough cuttings vibroplast and a small cut "noise". These works are best done at the very end or do the very first to "fill" the hands.

If there is native noise insulation on the hood of the car, it should be left. In the absence of this, the thickest noise-insulating material can be used. But the vibration isolation is applied at a minimum, and therefore not more than 50% of the surface area. With its own weight, the vibrating plate can significantly weight the lid.

Conclusion

Noise isolation VAZ-2107 own hands - an interesting and exciting process. The results of the work, with the availability of quality materials and observance of technology, are simply impressive. Of course, to reach the heights of comfort of expensive foreign cars is unlikely to work, but audibility inside the cabin will be close to ideal. You can forget about the majority of external noise and enjoy the new sound of the old speaker system.
