Almost all vehicles, especially older cars, have problems with noise. These issues are made even worse if you have upgraded your sound system or vehicle in any way. To keep your car quiet isn’t enough just blocking outside noise. You also need to reduce the noise made by your car. Vibrations, rattling, loose parts - all of these things contribute to unwanted noise.The factory sound insulation does not always provide comfort for the passengers. Factory noise insulation materials are usually inexpensive and small parts. We recommend installing additional noise insulation for a comfortable interior.
Best solution for noise and heating
Noises (they are also sounds) in the car can occur both inside and outside. Interior noises - squeaks are mainly caused by the rubbing of the interior parts against each other. External noises can be caused by the vibration of the body itself - resonating noises, as well as by the sources from the outside. Therefore, the task of the car's noise isolation can be divided into three parts: noise reduction, noise isolation and antiskrip.
These works shall be performed in complex, because it is necessary to carry out noise isolation of different body elements in order to reduce the noise to the comfortable level. Such works are carried out with the use of damping materials, which are good at absorbing noise and vibration vibrations. We carry out noise isolation:
- Doors and cards
- Arches of wheels, underfenders
- Cabin beneath, engine bulkheads
- Trunk and rear fenders
- Roof and uprights
- Hood
The vibration dampers are excellent at absorbing all vibrations and converting them into heat. Vibration dampeners are bitumen-mastic tiles that are glued to the car body. They are selected depending on its thickness. Also these materials contain anti-corrosive substances and are designed to protect the body from corrosion. Special sound insulators do not let any outside sounds through due to their porous structure. Also, these materials effectively retain heat inside the car. With the help of anti-squeak materials, friction between all elements of the trim is prevented.
Before the work is carried out, the interior is completely disassembled and the electronics are disconnected. All surfaces are degreased before gluing the soundproofing, as this ensures the most reliable attachment of the insulating materials.
Vibration-damping materials are usually used to work with the arches. This is due to the fact that the wheel arches are located close to the main sources of noise. In addition, we recommend gluing vibration dampers on the fenders.
Special attention is paid to the soundproofing of doors, because they allow a lot of external noise to pass through due to their large surface area. In this case, soundproofing materials are applied to all internal surfaces of each door. Here it is better to use lightweight materials to prolong the life of the hinges and limiter.
The creation of a soundproofing layer on the ceiling is of great importance, as it has a large area and a low degree of rigidity. As a result, it is through the ceiling can easily penetrate the sound vibrations and vibration. This is especially noticeable when driving at high speeds and in rainy weather.
The soundproofing of the underbody is performed with materials that are designed to withstand heavy vibration. When treating the underbody, soundproofing materials of great thickness on a bitumen basis are used. Only in this case, they will well dampen the vibrations of the body.
Thanks to the noise insulation of the hood, the noise coming from the engine is removed. As a result, it significantly reduces the overall level of noise when the car moves in traffic jams. Vibration dampeners are used to treat the hood, which are used to cover all surfaces.
After the work is completed, the interior is assembled and the electronics are connected. Clips are replaced with new ones, by default. Installation of noise insulation will eliminate extraneous noises in the car while driving and will provide the necessary comfort for the driver and passengers.
