How to make noise insulation in the car?

Before making noise insulation, you need to know exactly what result you need to achieve: better sound of music, freeing the cabin from squeaks, more comfort, and only after that you should select materials based on the task. When financial resources are limited, and the work is done personally, you should not strive to make the whole car soundproof, but this should be done partially, gradually improving your experience. You can start with soundproofing doors, and then the trunk, floor and other parts of the car will go.

What materials are needed if you do everything yourself?

First of all, you need to stock up on a building hair dryer (this is necessary if the noise insulation sheet is thick), a stitching roller (for normal stitching it is recommended to get one, moreover, it is inexpensive, and the benefits of it are large), scissors (for , to cut sheets), solvent (for degreasing the surface) and, of course, patience and the desire to make "Shumka".

Materials that are necessary for sound insulation

We recommend using materials from StP (Standartplast), which is one of the best on the market. The range of StP is divided into the following types:

Vibration absorbers;
Sound attenuators;
Antiscriping;
Sealants;
Strengthening materials.

Consider specific recommended materials.

StP Silver New

The vibration absorbing sheet is very flexible and flexible. It is a self-adhesive base with aluminum foil. Drawing markup allows you to cut a sheet into several parts you need size. The material is moisture resistant and does not decompose from exposure to the environment, has anti-corrosion properties and properties of sealant. It is easily glued to uneven surfaces and absolutely does not require heating during installation.

Material application: doors, hood, roof.

StP Vibroplast Gold

Almost the same as Silver, but thicker, which means it has the best vibration insulation parameters. The coefficient of mechanical loss is 0.33. Weight-4 kg/m². Sheet height is 2.3 millimeter.

StP Bimast Bomb Premium

Vibration-absorbing material. It is a multi-layer structure consisting of a front aluminum layer, a sheet with a bitumen base, and a sheet based on a rubber composition. When mounting is required to warm up to 40-50 ° C. The sheet has moisture protection and the highest efficiency of vibration isolation. Ideal for styling acoustics in the car. Mechanical loss factor is 0.6. The thickness is 4.2 millimeters.

Material application: floor, trunk, doors, roof, cladding.

StP Splen 3004

Sound insulation material with a glue base. It has high thermal insulation properties. The sheet of material is very easily mounted on vertical or uneven surfaces, it is moisture-proof and does not decompose from environmental exposure. The weight is 0.42 kg/m³. Sheet thickness is 4 mm. StP Splen 3004 can be used in the temperature range -40-+ 70 ° C.

Material application: floor, trunk, doors, roof, cladding.

There is also a StP Splen 3008 with a thickness of 8 mm

The material "Splen" is applied with a second layer on the vibration isolation. In order to make a strong connection, the surfaces that are glued together must be clean and dry. Acetone can be used to degrease the surface.

The most optimal temperature at which the insulation is mounted is from 18 to 35 ° C, which guarantees the preservation of the adhesion properties (reliable adhesion of two surfaces) in the temperature range from -40 ° C to + 70 ° C. At a temperature of +10 degrees it is not recommended to apply “Splen”, since the adhesion will be extremely low. Adhesive tape must be applied without stretch. The protection layer is removed right before application.

StP Bitoplast A5K

The material is intended to absorb the sound of medium and high frequency, as well as for antiskripnogo effects on the plastic lining of the cabin (side racks, door cards, ceiling, elements of luggage carrier fasteners). In addition, a sheet of material has excellent thermal insulation properties. The bituminous impregnation of five-millimeter polyurethane foam reliably protects its exposure to moisture, ultraviolet radiation, from the appearance of odor, retaining its useful properties for up to twenty years. Viscous elastic material with a layer of glue has the widest working temperature range -50 to + 100 ° C.

Material application: plastic, plating.

StP Madeleine

StP Madeleine-a black decorative sealing material with a fabric base. The thickness of the sheet of material is 1.5 millimeters with a layer of glue, which is protected by a special anti-adhesive gasket.

Material application: plastic, plating.

StP Accent 10 KS

Sound insulation material. The structure includes a metallized film, polyurethane foam and mounting adhesive layer. It has an excellent operating frequency range and good thermal protection. Able to absorb up to 90 percent of noise. Thickness is 10 mm. The material retains its performance at temperatures of -40-+ 100 ° C.

Material Application: hood, roof.

Hood Insulation

Some car owners mistakenly believe that as soon as they make soundproofing the hood, it will save them from the noise that comes from the engine. This is not entirely true. Soundproofing hood is carried out to achieve thermal insulation of the engine during the winter period. To do this, you need materials StP Accent 10 KS and StP Silver New.

When soundproofing the bonnet, it is important to consider the weight of the material. If the hood is too heavy, soon the hood shock absorbers may leak and they will have to be replaced with new ones.

It is recommended to use StP Silver New (or similar) as a vibration insulation material, which has a low weight. Specialized material Accent 10 CS is used as thermal insulation, which is intended to keep warm inside the engine compartment in winter. The material is resistant to heat and will not catch fire due to high engine temperature. As for thickness, here the more, the better.

It is important to pay attention to whether there is a factory insulation in the car. It does not need to be thrown away, the proposed insulation will then become auxiliary. During the selection of the thickness of the "Accent" you need to work on this principle, so that later it was easy to put on the full soundproofing of the hood.

Some cars do not have a factory soundproofing hood, then the hood insulation is needed, and a thick material of 15 millimeters is used as insulation. Together with vibration isolation, it will give the best effect.

Door Insulation

Noise isolation of the car door is carried out in order to get rid of annoying noise from the outside and to improve the sound of the speakers in the car. Even the simplest door insulation can create a real miracle, and the music after it will play much better.

In order to get at least the minimum noise insulation of doors, you need only vibration-proof material, such as StP Silver New or StP Gold New. It must be pasted on the inside of the door opposite the speaker. The larger the area of vibration isolation coating, the better, and the thinner the metal, the greater the amount of vibration isolation required.

When making Shumkov car doors need to take into account the weight of materials. It is not necessary to heavily weight the door, as over time it may sag and you will have to buy new hinges. If you need to significantly improve the sound of music, it will not work out with small means. We need a cumulative approach and noise isolation in at least 4 layers.

The first layer is glued to the inside of the door. The material used is StP Silver New or a small amount of StP Bimast Bomb Premium in the space behind the speaker. The second layer on top of the vibration insulation is splen 4-8 mm.

The next step will be insulation outside the door, under the door cards and is suitable for lovers of high-quality car audio. It is necessary to completely seal the technological holes in order to make the volume of the door airtight where the speaker is playing. In addition, after this operation, the rigidity of the door will increase, and this has a positive effect on auto sound. Silver New is plastered on the outside and Splen on top for sound insulation.

Next comes the soundproofing door cards. This is done so that they do not creak and do not make any extra sounds. Useful anti-scratch and noise-absorbing material "Bitoplast". The more massive it is, the better. It is important to remember about the "crickets" inside the door and, in addition, glue the traction and handles with StP Madeleine.

Insulation of the rear doors is performed by analogy with the front. If there are no speakers in the door, the number of layers is less and the type of vibration isolation is used easier.

Soundproofing ceiling and roof

Roof noise insulation is used to reduce outdoor noise, such as rain, and also to remove crickets.

StP Silver New is used for the roof. Weight is important, because the heavier the ceiling, the higher the center of gravity of the car, and this has a bad effect on handling. StP Splen 4 or 8 millimeters is used as a silencer, perhaps even in two layers. Opportunities in sound insulation of the roof are limited only by the normal installation of headlining back into place.

Car noise insulation

The floor is insulated to shield the noise coming from the road, as well as the impact of rubble on the bottom of the car. To do this, use the best quality vibration noise insulation materials. On the floor of the car, they usually put the vibration insulation of StP Bimast Bombs Premium, and a layer of noise insulation of StP Splen 4 or 8 millimeters is placed on top.

It should be borne in mind that StP Splen large thickness is inconvenient to lay, so it is better to use a material of reduced thickness, but lay it in two layers. Be sure to lay on the entire surface of the floor, without gaps. The larger the coverage area, the better.

Also, when laying the material on the floor, you need to pay attention to the places of the wheel arches on the side of the cabin-these are very important places in terms of noise insulation. Best of all would be pasting arches in two or three layers of thick materials, and as a vibration isolator you should use StP Bimast Bomb Premium or StP Vibroplast Gold in 2 layers.

Soundproofing of the trunk and wheel arches

Whenever possible, it is necessary to glue the spare wheel niche with vibration insulation and soundproof the plastic lining of the trunk with Bitoplast material. Noise wheel arches is needed to improve the comfort in the car. If done correctly, the noise from the wheels and the roadway will be minimized, and in the winter time you will not hear the noise from studded rubber.

The sequence for soundproofing wheel niches is as follows: fenders are removed (they should not be thrown away, as they are not bad insulators). Next you need to clean the dirt and apply on the inner layer of the arch material StP Vibroplast Gold. It will not be superfluous and anti-gravity wheelbase treatment. On the one hand, it will protect against the effect of corrosion, and on the other, it is also insulation.

In addition, you can soundproof plastic fenders. It is enough to stick StP Silver New material on the reverse side and StP Bitoplast as sound insulation. Next, the fenders are put on the spot. If everything is done correctly, the impact of stones on the niche of the wheels will not be heard.
