Do-it-yourself noise insulation of Lada-Vesta: step-by-step instructions. Sound insulation STP

Comparison of the noise level of Lada-Vesta with similar models

According to subjective sensations, the noise level in the cabin while driving has decreased compared to the Lada-Granta, which is a budget version of the Russian car. However, these are models of different classes and different price categories, so comparing them is not entirely correct.

Recently, a comparison was made of the noise level of the Lada Vesta with another model produced on the Togliatti assembly line, but under the Japanese brand Nissan Almera.

The measurement took place on the ring road of St. Petersburg. This location was chosen for two reasons. Firstly, here you can accelerate to a decent speed, and secondly, heavy traffic on this highway creates additional noise.

The measurement took place at speeds of 60 and 100 km/h. The result showed better sound insulation for the Lada Vesta.

Based on the test, it is clear that the company’s engineers have done work to improve the ergonomics of the car. Especially considering that these cars are in the same price range.

What the reviews say

technical characteristics of Lada Vesta sw cross. clearance of Lada Vesta St. cross Lada Vesta has been in the hands of many journalists who tried to find its advantages and disadvantages. If we talk specifically about sound insulation, one of the first opinions on this matter was expressed by Anton Avtoman in his video review. Even before starting to drive, “playing” with idle speed, he noted the noisy engine and the need to install additional noise.

Autoreview experts checked the sedan more globally. To get an assessment of Vesta's noise insulation, they compared it with competitors: Ford Fiesta, Kia Rio, Renault Logan, Volkswagen Polo. According to test results:

1. The Kia Rio and Ford Fiesta received the highest score.
2. Volkswagen Polo and Lada Vesta have average noise levels. In terms of acoustic and vibration comfort, both sedans are approximately on the same level, but Vesta’s engine turned out to be a little quieter than that of the German.
3. Renault Logan ended up in last position.

What materials are used to reduce noise

For sound insulation, materials with different properties are used, depending on the place of their application. Some of them are combined. They can be roughly divided into categories:

1. Soundproofing. This type of material is designed to reduce noise levels. They glue the metal elements of the body: doors, roof, rear fenders.
2. Vibration isolation. Used to dampen vibration coming from the bottom, engine compartment and wheel arches. The base is rubber or bitumen mastic.

3. Thermal insulation and noise absorption. These materials are used to insulate engine compartments. Their main property is not only to obstruct the passage of acoustic waves, but also to shield thermal energy. In winter, it is very important to minimize engine cooling time. Each start in cold weather leads to increased wear of the cylinder-piston group, as well as other elements. These materials look like foamed plastic on a foil base.
4. Anti-creak. These materials look like adhesive-based canvas tapes. They are used to glue plastic parts such as shelves, door trims, and instrument panels.
5. Liquid sound insulation. Its use has two purposes: noise elimination and anti-corrosion protection. Used to protect the underbody and arches of cars from the outside. After application, it partially or completely hardens.
6. Sound-absorbing mats. By themselves, they are not able to increase sound comfort, but in combination with other measures they will give results.

↑ Procedure

Any work on installing automotive sound and vibration insulation on a car such as the Lada Vesta will include a number of actions that must be performed in a specific order. Usually the work takes no more than two or three days, although auto repairmen sometimes reduce the period to one and a half days.

In order to make sound insulation, you need:

• remove the vehicle trim, providing free access to the metal body;
• metal surfaces are thoroughly degreased using the liquid mentioned above;
• noise and vibration insulation membranes are cut;
• vibration-absorbing material is placed directly on the metal;
• on top of the previous one - a layer of sound insulation;
• for sound insulation - an anti-creaking layer;
• the casing is returned to its place.

Important! The insulation area must be at least 70% of the area of ​​the metal structure of the vehicle. When laying vibration insulation, it must be warmed up well with a hairdryer and the sheets are rolled with a roller so that there are no air pockets and the texture is no longer foil-like

If bubbles still form, they are carefully pierced

When laying vibration insulation, it must be warmed up well with a hairdryer and the sheets are rolled with a roller so that there are no air pockets and the texture is no longer foil-like

If bubbles still form, they are carefully pierced

Unlike vibration isolation, it is important to maintain the integrity of the sound insulation layer. The roll is carefully cut according to the measurements taken

Then the material is sequentially glued, finishing the work by rolling with a roller.

↑ Hood

A special feature of soundproofing work on the hood is that this part of the vehicle does not require large layers of insulators. Just a thin layer of vibration insulation and insulation is enough. Accent material is usually used as the latter.

↑ Roof

Insulating the roof will require first removing the interior sheathing. To do this, you need to unscrew all the parts that are attached to it - these are all kinds of handles and lampshades. Once this is done, the sheathing material can be easily removed.

The main feature of roof sound insulation is the need to use sufficiently dense sound absorbers. The reason for this is that a sound wave “walks” directly under this structural element of the car.

↑ Doors

Doors are one of the noisiest places in any car and Lada Vesta is no exception. Therefore, when soundproofing them, you will have to apply all three layers: protection from vibration, sounds and creaks.

In order to get to the metal frame, the first thing you need to do is unscrew all the handles. As with the ceiling, the interior lining material can then be easily removed. It is worth considering that the door frame is insulated not only by the external metal, but also by the internal rigidity frame.

When gluing insulating material, it is worth considering the need to use solid sheets in places where there are technological holes. The rods, places where the casing is attached and the wires are covered with anti-creaking material. Holes for fasteners are cut out in the sound insulation.

How to plan your work

It will take several working days to complete soundproofing work on the Lada Vesta. The volume is large: you need to disassemble the interior, remove the seats, remove the factory carpet. In addition, the door and ceiling trims are removed. If you completely glue the engine shield, you will need to dismantle the instrument panel and console.

In the engine compartment, the hood protection is removed, and in the luggage compartment, the internal trim must be removed.

For convenience, the work can be divided into four stages. On the first day, carry out all disassembly work. In the second, glue the bottom, arches, and trunk floor. In the third - doors, roof, hood. Spend the fourth day assembling the car.

Soundproofing the floor of Lada Vesta

What box is on Vesta Cross 1.8. What gearbox is on the Lada Vesta? how to determine which gearbox is on a Lada Vesta car

If the first two stages could be called light, then soundproofing the Lada Vesta floor will be more difficult. First we need to remove the seats. First we remove the back seat, and then move on to the front. After which you need to remove all the sill trims, the central tunnel with the armrest and other small plastic elements.

After this, we remove the carpet and standard sound insulation. If the factory vibration insulation does not hold up well or peels off, then it is best to remove it. After that, we degrease everything and move directly to the sound insulation itself.

We apply StP Aero Plus material to the metal floor, joint to joint. We will also cover approximately 100% of the area. As usual, we leave the amplifiers open. On top of this material we apply StP Accent Premium 6 mm, also in a continuous layer, or StP Barrier 4 KS. And on top of it all we glue with StP NoiseBlock material 2 mm thick.

At this stage, the wheel arches of the Lada Vesta are immediately soundproofed. Sound insulation is made with Biplast Premium material, which is used instead of StP Aero Plus, and the remaining two layers - Biplast and Premium Accent - are glued in the same order.

After the work has been done, we assemble the interior in the reverse order and move on to the trunk.

Disassembling the interior

In order to make soundproofing of the Lada Vesta with your own hands, first disassemble the interior:

1. The first thing you need to do is remove the plastic trim on the windshield pillars. To do this, remove the door sealing rubber, then pull the trim with a little force until the three latches snap off.
2. The next step is to remove the plastic thresholds. If this is not done, it will be impossible to remove the carpet covering the bottom, as well as remove the plastic lining of the door pillars. First, the door seals on all openings are removed. Then the screws from the plastic thresholds are unscrewed around the perimeter. At the same time, the plastic lining of the rear wheel arch is removed.
3. Then there are the plastic door pillar trims. This is necessary for subsequent dismantling of the ceiling cladding. First the seat belt is removed. To do this, unscrew two bolts: one that holds the belt carriage from below, the second that secures the belt eyelet from above. After this, the top trim of the door pillar is dismantled.
4. Removing the ceiling trim. It is attached using six clips, sun visors, three passenger handles, and a lampshade. It is removed as follows. First, the six bolts securing the handles are unscrewed. Then the eight screws securing the visors are unscrewed. After this, using a special spatula, the clips are removed: three in the center of the ceiling and three near the rear window. The trim is then removed through the front passenger door.
5. Removing the front seats. They are secured with four bolts. First you need to move the seats back as far as possible. Then remove the front bolts securing the slide to the floor. After that, move the seats forward and unscrew the rear ones. After this, they can be removed from the interior.
6. Removing the rear sofa. The lower seat is attached using two hinges. You just need to lift the sofa by the bottom so that the hinges come out of the lock. The rear backrest is secured at the bottom with four bolts, and at the top with clamps on the sides.

Self-soundproofing Vesta

In auto repair shops, the price of soundproofing a Lada Vesta can be up to 30-40 thousand rubles. By doing everything yourself, you can save almost half of this amount.

We will consider sound insulation of the entire car, but the owners of the Lada Vesta say that it is quite possible to limit it to arches and doors.

Materials and tools

The sound insulation of a car is usually made up of a vibration and sound-absorbing layer. You may also need material to prevent squeaks. Among the best manufacturers the following will be highlighted:

• STP
  is one of the market leaders. It has a good assortment and acceptable quality; one drawback is that sometimes you have to overpay for the brand.
• STANDARD-Profi
  – the quality is no worse than STP, but the prices are more affordable.
• Noise Control
  – produces inexpensive products with quite satisfactory quality.
• Noise
  – sound insulation does not always live up to expectations, but the cost is appropriate. We can say that this is the best budget option.
• Deloud
  is a manufacturer of premium sound-absorbing materials that have the highest performance. But this pleasure does not come cheap.

To carry out the work you will need:

• construction hair dryer;
• stitching roller;
• scissors;
• stationery knife;
• marker;
• roulette;
• degreaser or solvent (you can use regular White Spirit).

General procedure

Do-it-yourself noise insulation of Lada Vesta involves a standard algorithm:

• The casing is removed to provide access to the metal;
• The metal surface is degreased;
• Soundproofing materials are cut;
• The vibration absorber is installed;
• Sound absorber is installed;
• Anti-creaking is installed;
• The casing is being assembled.

If necessary, vibration isolation can be glued in separate pieces. Most of its types require pre-heating with a hair dryer. The vibra should be thoroughly rolled with a roller until the foil texture disappears

If bubbles form underneath, carefully pierce them with a utility knife

The sound insulation layer must be solid. By taking measurements from the surface where the Shumka will be glued, you can mark the roll and carefully cut it. The material is glued sequentially with gradual tearing off of the film. At the end you need to go through the roller thoroughly.

Complete soundproofing of the Lada Vesta may take 1-2 days, depending on your skills.

Hood

It is recommended to install light vibration insulation on the hood cover. It should also be remembered that the insulation of the engine compartment must have heat-saving properties in order to maintain temperature in the winter. Accent material is perfect for these purposes.

Roof sound insulation

Sound insulation of the roof To remove the ceiling lining, unscrew all the ceiling handles, remove the lampshades and racks. As a result, the sheathing should come away freely, and you can work with the metal surface of the roof.

It is better to use a dense sound absorber, which will allow you to fight the sound wave traveling under the casing.

Soundproofing doors

Doors must always be insulated, because this is one of the “noisiest” places not only on Vesta, but also on other cars. Therefore, everything needs to be done with the utmost quality.

Two layers of insulation (vibration, sound) are glued to both the outer metal and the inner frame. Technological openings must be covered with a single sheet. Holes are cut out for tie rods, clamps, etc.

It is recommended to cover all wires, rods and places of contact between the door trim and anti-squeak.

Arches

To carry out the work you will need to remove the wheel and locker. Before degreasing, the surface of the arch is cleaned of dirt.

It is better to use a vibrating layer on a bitumen basis. It will not be very convenient to glue a whole layer, so it is better to cut small pieces. The joints are coated with rubber bitumen mastic. The entire surface is treated with it.

The sound insulation layer is glued to the locker.

Floor and trunk

The seats, carpets, center console and upholstery are removed from the interior. In this case, three layers of materials are usually laid:

• vibration absorber (it is recommended to install more advanced options such as Bimast Bomb on the arches and under the seats);
• sound absorber (8-10 mm);
• soundproofing NoiseBlock.

The video demonstrates all stages of soundproofing Vesta.

Removing the console

All that remains in the cabin is the carpet and the insulation underneath. They are held only by the center console, which consists of several parts. To remove the plastic and the closing handbrake, you need to unscrew the two bolts at the edges and remove the plastic plug near the handbrake lever. The back of the console will become free and can be removed.

The front part is more difficult. In front, along the edges of the tunnel, there are two plastic plugs in the area of ​​the driver’s and passenger’s feet. Under these plugs the fasteners for the tunnel linings are hidden, so first the plugs are removed, then the screws that secure the lining are unscrewed. In addition to these fasteners, there are several more screws in the area of ​​the gearshift lever, but to get to them, you need to remove the plastic lining of the console near the lever and simultaneously disconnect the electrical wiring connectors. The last two screws hold the console near the engine shield, unscrew them and remove the console completely.

Now you can remove the carpet, which consists of several parts.

How to remove the door trim of a Lada-Vesta

The work takes place in several stages:

1. Remove the plastic triangle covering the side mirror mounts. To do this, you need to pry it off with a plastic spatula.

2. Disconnect the electrical mirror control connector.
3. Remove the lighting shade at the bottom of the casing.
4. Unscrew the three screws at the bottom. A T 20 sprocket is used.
5. At the end of the casing there is a plug under which the screw is hidden. You need to unscrew it.
6. Unscrew the screw located inside the handle next to the power window control unit.
7. Remove the power window control unit and disconnect the electrical connector.
8. There is another screw under the control unit. You need to unscrew it.
9. Use a plastic spatula to unclip the fastening clips along the perimeter of the casing.

We glue the arches

Sound insulation of Lada Vesta arches is the main component of the fight against the source of noise. When driving on asphalt at high speed, the tire tread emits a hum, which enters the cabin through the arches. Both the road surface and the tread pattern play a big role.

To reduce the noise coming from the arches, sound insulation STP Noise Liquidator is applied to them. It is a two-component mastic in jars. Apply with a brush to a clean, grease-free surface. One can is used for one arch.

STP Silver sound insulation is glued to the plastic wheel arch liners. This material belongs to the category of vibroplasts; it dampens vibration well from the impacts of small stones on the fender liners of the car.

Soundproofing of the Lada Vesta is complete.

The car has become truly more comfortable. Both the driver and passengers will be able to appreciate this. Noise insulation at medium and high speeds has changed dramatically, for the better. The car's microclimate has stabilized. The interior will not cool down so quickly in winter and will not heat up so quickly in summer. The sound of the standard audio system has been improved. The outer metal of the doors has become less susceptible to dents from small impacts (it is precisely such impacts from opening the doors of neighboring cars in the parking lot that lead to dents). And so that you can see what a great and meticulous work we have done, we will provide a full photo report.

We insulate the doors

Soundproofing of Lada Vesta doors is carried out comprehensively. To make it easier to apply vibroplast to the inner surface, the speakers and window lifts are additionally removed. Sheets of sound insulation must be marked in advance and cut according to the pattern. After gluing, they need to be rolled with a roller or pressed firmly against the surface of the door.

The outer frame is also pasted over, but a sound absorber is used here. For example, NoiseBlock or “Biplast”. The material is taken with a thickness of 0.8 cm - it can be glued not to the door frame, but to the plastic door trim on the inside.

Soundproofing of the engine compartment

The factory insulation of the Vesta engine compartment under the hood is quite high quality. If desired, it can be brought to perfection by improving the area on the salon side. Sequence of work:

1. First, the dashboards and shields are dismantled, all plastic surfaces are degreased.
2. The panel is covered with a 2 mm thick sound absorber. As in other works, it is recommended to heat the sheets (if this is required according to the instructions) and roll them with a rubber roller.
3. Next, the area is treated with a sound absorber.
4. All removable parts are upholstered in a similar way - the casing, the glove compartment lid.
5. It is enough to reinforce the upper part of the air ducts and heater with one layer of sound absorber.
6. Panel fastening areas and wire harnesses are treated with anti-creaking.

The procedure will take 10-12 hours.

The price of materials for complete noise reduction will be 15-17 thousand rubles.

It is worth considering that complete sound insulation of a Lada Vesta SV in a car repair shop will cost 7-8 thousand rubles. You can look for a service where some part of the work, for example, the trunk or arches, will be performed as a bonus.

Video of complete noise reduction with your own hands:

Ceiling gluing

When working on soundproofing the car interior, special attention should be paid to the roof. It is a large sheet of metal that creates good acoustics. Vibrations that occur in the roof area are damped only with the help of amplifiers. But it happens that the amplifiers peel off from the metal sheet, and it begins to vibrate in time with the engine.

Light materials are used to cover the roof so as not to create additional load. Vibroplast sheets with a thickness of no more than 2-3 mm are taken. If there is factory felt insulation on the roof, it will need to be removed. Stiffeners should not be pasted over. If they are covered with sound insulation, condensation will accumulate inside, which will lead to corrosion.

You need to glue a layer of sound absorber on top; “Accent 8” with a self-adhesive foil base is suitable, it is light in weight - you don’t have to worry that it will “pull” the roof down.

Is it worth it to soundproof Vesta yourself?

By independently enhancing the original sound insulation, Vesta owners will receive a number of advantages. First of all, get rid of the creaking of all plastic elements. Besides:

• the noise level will decrease under any operating mode;
• it will be possible to drive the car in complete silence and talk to passengers without straining your voice;
• when traveling long distances, fatigue will decrease;
• the sound of the speakers will improve;
• drafts will disappear even at high speeds, due to this the temperature in the cabin will become stable.

The body will also receive additional benefits, since it will be less susceptible to corrosion.

With high-quality insulation, the surfaces are first cleaned, then degreased, and the insulation is properly rolled and a reliable adhesion is achieved that prevents the penetration of air and moisture.

However, self-made shvi also has its disadvantages. Interior elements may be damaged during dismantling and reinstallation. If there is an error with the thickness of the material, some parts will be installed offset. There will be places for condensation to accumulate. Due to moisture, corrosion will quickly begin to develop.

Soundproofing Vesta's interior

High-quality insulation can only be done with experience. It is recommended that the first layer of ShMI—vibration isolation—be ordered from a service center, where the material will be rolled tightly without bubbles or unevenness. It is easier to install the next 2 layers yourself: the soundproofing material is covered with glue. It is enough to clean and degrease the surface, remove the protective layer and press the sheet.

Soundproofing the underbody and trunk

Sound insulation of the Lada Vesta trunk and bottom can be done in several ways. The first is when an anti-gravel coating is applied to the outside of the bottom in several layers, which performs the function of noise insulation and anti-corrosion protection - these are polymer substances that are applied with a spray gun. Once cured, they form a thick, porous film and add weight to the car, increasing its stability.

The second option is to apply a thick layer of bitumen mastic from the inside of the body. Bitumen perfectly dampens sound vibrations, increasing the sound insulation of the Lada Vesta. In addition, you can use vibroplast of large thickness - from 5 mm and above.

When gluing the floor, you need to take into account its shape, especially the places where water can accumulate, so the vibroplast needs to be pressed very carefully, without leaving any gaps.

You can use bitumen-based roofing materials. When heated with a hair dryer, they will perfectly take the shape of the bottom without leaving any gaps.

↑ recommendations from manufacturers

Today there are many manufacturers of sound insulation systems for cars. Their products differ in quality and price. But, despite all the differences, they give general recommendations for improving protection from unnecessary sounds. They look like this:

• for the ceiling it is worth using modern felt absorbers;
• metal parts should always be degreased;
• external metal is covered with a vibration damper;
• car doors require at least three layers of sound insulation
• wheel arches, trunk and floor are insulated last.

By following these recommendations, the owner of the Lada Vesta will significantly improve the comfort of travel.
