Soundproofing the hood of Lada Largus - instructions with photos and videos

Soundproofing Lada Largus (Lada Largus)

performed by our team in 9-10 hours in the presence of the car owner. You, of course, may not be present, but we always insist that the owner of the car be with us during the work, especially since for this we have comfortable sofas with tea, coffee, cookies and WiFI right in front of the cars. It’s a pleasure to work with Largus, because it is more of a foreign car than a Russian car - the parts, pistons and their layout are built on the basis of Renault Logan and the assembly and disassembly of the interior occurs predictably and in compliance with all factory standards.

It is worth noting that 1 hour before the arrival of the car by appointment, we cut all the sound insulation according to our proprietary patterns and place the sheets in a special oven to heat up to a temperature of 50-55 degrees, so that subsequently we do not waste time heating each sheet. Every day we soundproof several cars at once, so our owners will not be bored - they can not only exchange impressions about our work, but also share their experience in operating their cars. So, let's see what the factory sound insulation of the Lada Largus is and how it can be significantly improved.

Sound insulation of the hood of Lada Largus

begins with cleaning and degreasing the surfaces, onto which we will apply vibration damper Comfort mat Dark D3, as well as a noise absorber based on Fusion 3 mm polyurethane foam.

Soundproofing the roof of Lada Largus

carried out by a master wearing clean gloves so that not a single spot or snag remains on the ceiling trim and racks. We remove the ceiling lining and prepare the roof metal for vibration insulation.

Lightweight and effective vibration insulation Comfort mat Premium Dark D3 3 mm thick. applied to the roof metal and rolled with a special tool.

The roof area is quite large. Do not neglect it when soundproofing.

Thick, high-density Felton 10 felt will protect the cavity between the roof and sheathing from the propagation and reflection of airborne sound waves. This is a moisture-resistant felt sound absorber that is an ideal trap for sound waves reflected under the ceiling lining.

Soundproofing doors Lada Largus

It is produced using a multilayer scheme, in which both the outer metal of the door and the frame itself are processed. And before you start gluing, degreasing is strictly necessary - this will increase the adhesion of the material and ensure its reliable fixation.

Lightweight (no more than 1500 per sheet) vibration damper Comfort mat Premium Dark D3 takes its place on the outer metal of the door. We have all the necessary special tools for high-quality rolling of material even in the most inaccessible places.

Then the light membrane sound insulation Comfort mat Integra 6, which is 100% moisture-resistant material, takes its place on the door.

The door frame also needs damping and we do it using Premium Dark D3 from Comfort mat.

We apply noise-absorbing “pyramids” Comfort mat Soft Wave 15 to the door trim, which not only perfectly absorb sound, but also ensure a reliable and tight fit of the trim without crickets or squeaks.

In our special center, every day we carry out simultaneous soundproofing of several cars at once, so car owners can not only see how neighboring cars are made, but also exchange impressions with each other.

Sound insulation of the floor, trunk and wheel arches of Lada Largus

performed immediately after finishing work on the ceiling and doors. At this point, approximately 4.5 hours have passed on our watch and the whole team is rushing to the most important part of the work, which will bring the greatest effect in combating noise.

We remove from the salon everything that could prevent us from doing our job beautifully: seats, console, carpets, upholstery. Degreasing of the body is carried out with a special composition that does not spoil the paint surface of the car.

Since all of our vibration-proofing material is not only cut in advance, but also evenly heated in a special oven to 50-55 degrees, the work of applying vibration-proofing to the floor of Largus takes no more than 1 hour.

On the floor we use a premium series of Comfort mat Ultra Loker 4 material. Here we have a two-layer foil design and an exclusive mastic recipe, which is manufactured only for the needs of Auto-Loker on a separate Comfort mat conveyor. The high frame structure of the material allows you to most effectively combat the structural noise of the metal floor and arches, which is the source of the most unpleasant wheel noise. The material is not supplied to retail and is produced by the flagship Comfort mat installation center in Moscow, the Auto-Loker company.

Soundproofing on Lada Largus

People are thinking about soundproofing a car in cases where they are dissatisfied with the quality and to build an audio system. The sound inside the car directly depends on the percentage of extraneous noise. It is clear that the more there are, the worse the sound will be reproduced.

Note. Even a simple noise insulation operation, which does not involve the full range of work, significantly increases the sound quality. This immediately becomes noticeable even to a non-professional.

To begin with, before carrying out work, you need to set the final goal, which implies the result in the end. If the process concerns improving acoustic properties, then the purchase of special materials is necessary. If the owner wants to get greater driving comfort from sound insulation, prepare other materials.

Note. Let us note one important detail. If the budget is limited and the work is carried out with your own hands, there is no need to pursue a full range of sound insulation. In this case, you can isolate the machine not entirely, but in parts. In this way, you can eliminate large-scale errors and save your budget, because the cost of repairs will be minimal.

Soundproofing in Lada Largus

How is Lada Largus soundproofed?

1. Doors: we treat the inside of the door with vibration-insulating material, which will smooth out vibrations from passing cars.

2. Doors: acoustic preparation in Largus should begin with surface treatment and technical openings.

3. Door trim: to get rid of rattling and squeaks on the road, you need to treat the doors with anti-squeak, sound-absorbing material.

4. Trunk: glued with vibration and noise insulating materials in two layers - the first vibration insulating layer will remove vibrations from the engine.

5. Trunk: by treating the trunk with a noise absorber, we will get rid of the noise from the power unit.

6. Floor: the removal of the standard carpet is followed by the process of vibration and noise insulation.

7. Floor: the front part of the cabin in the Lada Largus has the highest degree of vibration load, so noise-heat-insulating material is laid as a second layer over the entire treated surface.

8. Soundproofing the ceiling in Largus: before applying the first vibration-proofing layer, you need to dismantle the ceiling and prepare the surface.

9. Ceiling: sound-heat-insulating material will eliminate the ringing effect during rain, reducing noise in the space above the ceiling panel.

10. Fifth door: an additional measure for noise insulation of the Lada Largus is the treatment of the fifth door of the car with vibration and noise insulation material.

11. Fifth door: the car door rises quite high, which may cause an additional hum. Therefore, this area must be treated with anti-creaking sound-absorbing material.

12. Sound insulation of the hood in Lada Largus: treatment with noise-absorbing material will serve as a good reflector of sound waves.

Materials

Materials for sound insulation

We read this paragraph very carefully, since all the most important things depend on the materials. If it is chosen incorrectly, all noise insulation work will go down the drain.

Vibroplast Silver

This is a very flexible and elastic material for carrying out noise. Differs in the following features:

• It is a polymer self-adhesive composition combined with aluminum foil;
• The material is made with a marking pattern, which is 5x5 cm squares, which makes it easy to cut the sheet into pieces of a certain size;
• Vibroplast Silver does not allow moisture to pass through, does not decompose over time and includes components for corrosion protection;
• The material, which also has the properties of a sealant, ideally fits on surfaces with complex terrain and does not require heating during installation.

Note. Any vibration-proofing material is assessed by its mechanical loss coefficient. For Silver vibroplast it is quite good (0.25-0.35 conventional units).

• By the way, this material will cover the floor of the Lada Largus, the doors and roof of the car, as well as other parts.

Vibroplast Gold

A material with almost the same properties as described above, but has greater vibration insulation.

BiMast Bomb

This material already absorbs sound rather than insulating. It is distinguished by the following features:

• The material is an “absorber” of a multilayer structure. BiMast is three layers: front (aluminum foil), bitumen (based on a bitumen composition) and rubber, protected by an anti-adhesive film;
• It has high efficiency, does not absorb moisture and does not decompose over time.

Note. This material has been named the best vibration-absorbing material in recent years.

Splen 3004

Soundproofing material with an adhesive layer. Differs in the following parameters:

• Has high heat-insulating properties;
• It is easy to cover vertical and curved surfaces with it;
• Does not absorb moisture and does not decompose from external influences;
• It is best to use it to cover the front panel of the Lada Largus interior, wheel arches, doors and tunnel.

Note. One of the features of Splen is that it is glued on top of vibration-absorbing material. In order for it to stick perfectly, you must follow the rule: the surfaces to be glued must always be clean and completely dry. Acetone or white spirit cleans such surfaces well.

Bitoplast 5

A material that is also called anti-squeak. Differs in the following features:

• Ideally eliminates squeaks and rattles in the cabin;
• Made on a polyurethane foam base with a sticky layer;
• The material is protected by an anti-adhesive gasket and special impregnation;
• Waterproof and durable;
• It is not subject to decomposition and has high thermal insulation properties;
• It is odorless and retains its noise-absorbing properties even at very low temperatures (up to -500 degrees).

There are a lot of materials for soundproofing. The table shows only the most popular ones.

Do-it-yourself noise insulation

Now let's move on to the direct process of soundproofing the Lada Largus. As a rule, today rarely anyone trusts this process to the masters at the service station. This is not only about the cost of services (which are sometimes so overpriced that you want to cry), but also due to a number of other reasons.

High-quality sound insulation Lada Largus

Absolutely any Russian driver with more than 1 year of driving experience is ready and able to handle high-quality sound insulation (the approximate time it takes any driver to learn to hold a key in his hands). The main thing is to buy materials, have the necessary tools at hand and know the basic rules (what to glue where). The tools you will need are the following:

• Hairdryer (construction). This tool is a must, because without it it is impossible to imagine pasting materials;
• Roller (roller). Also a mandatory tool needed for rolling materials. Its cost in stores is low (only about 200 rubles);
• Scissors needed for cutting pieces of a certain size from materials;
• Solvent. Instead, you can also use acetone, white spirit, and so on.

Features of choice

The selection of materials for performing soundproofing work on the Lada Largus body comes down to the following goals:

• reduce acoustic discomfort inside the cabin by reducing the level of extraneous noise;
• improve the musical capabilities of the audio system.

These two areas cannot be developed to the desired and identical effectiveness. Here the owner of the Lada Largus Cross will have to independently decide on the ultimate goal of the upcoming operation. For example, the desire to achieve improved sound while simultaneously reducing the transmission of vibrations from the acoustics to the body requires the implementation of improvements of a completely different nature in comparison with work to reduce outboard noise. The types of materials used will also make a significant difference.

An important aspect when soundproofing is carried out is the owner’s budget, at the expense of which he intends to implement the above measures with his own hands. If there is a limiting factor, then, as an option, you can lean toward partial revision.
