Noise isolation of Toyota Corolla

to the maximum includes: hood, ceiling, 4 doors, floor and wheel arches, trunk, rear fenders, trunk lid. For an additional fee: soundproofing of the torpedo and engine compartment or 4 wheel arches outside.

Noise isolation of Toyota Corolla. Another working day has come and we take another batch of cars for complete noise isolation of the cabin. One of them is a brand new Toyota Corolla. These cars come to us with enviable popularity, well, we in turn perform a full range of works to achieve comfort and suppression of acoustic noise in the cabin. The owner stays with us and will watch the whole process, well, we invite you to join us virtually. All our noise isolation is made strictly by appointment, so before the arrival of the car all the material in our company cut in advance on proprietary templates and heated in a special heater to a temperature of 50 degrees. Our team consists of more than twenty people and our work is organized in such a way that no one is distracted by breaks and do not interfere with each other during the implementation of noise isolation works. So, we start the full Toyota Corolla soundproofing, which will take us about 9 hours.

Then we use high-density acoustic Felton felt with a moisture-proof layer. After all, not for nothing in the expensive German cars (Audi, Mercedes, BMW) felt is used as factory noise insulation, including on the ceiling. Felt perfectly performs the role of trapping air sound waves, walking in the cavities of the roof.

The material is over 5 millimeters thick. That’s a tremendous impact on a vibration-loaded bottom. The modern chemical formula allows the material to be light, incredibly tenacious (adhesion) and efficient (KMP exceeds 0.63 units). This is a real exclusive for our customers from Auto-Locker and is produced on a separate factory assembly line specifically for our center. All this thanks to close cooperation and the status of the flagship center for the installation of noise insulation Comfort mat in Moscow.

Noise isolation of the Toyota Corolla is over. All our work took about 9 hours without a break in front of the owner of the car, who watched this “spectacle” with his mouth wide open. Not a single piston is broken, all linings assembled without gaps, as if the car had never been disassembled. Our masters have vast experience in soundproofing cars, the number of which passed through our hands are not hundreds but thousands. This Corolla has weighed 50-52 pounds of the most top sound absorbers at the time of publication of the photo report, increased rigidity and resistance of metal to accidental dents and bumps, and with it appeared feeling of the car class above. Working in the presence of the owner, we have very good feedback on the results of our activities, the owners recommend us to friends, and come to us again when they change the car. This is our incentive, which helps us to develop further. And now we invite you to take part in the play entitled “Noise control of your car in your presence. We have been working since 2007 and we have something to show you!

to the maximum includes: hood, ceiling, 4 doors, floor and wheel arches, trunk, rear fenders, trunk lid. For an additional fee: soundproofing of the torpedo and engine compartment or 4 wheel arches outside.

One of the factors that ensure comfort is the level of noise isolation of the car interior. It depends on the quality of the noise insulation materials that are placed on the hood, trunk, roof and wheel arches of the car. Over the course of use, the level of noise protection can decrease, which will ultimately lead to a reduction in the comfort of using the car. Often, the original Toyota Corolla 120 and 150 models of noise isolation, does not satisfy the motorist, and there is a need to increase the noise isolation of the vehicle.

On how to remove the original noise insulation, there are many videos, which show step by step how to remove the insulation materials from various parts of the car.

Hood Noise Insulation Installation

Hood noise insulation on the Toyota Corolla is installed in two steps:

  1. Hood Vibration Insulation

This step will protect the interior from vibrations resulting from the operation of the power unit. It is recommended to use materials that are not afraid of constant exposure to high temperatures (in the engine compartment can constantly remain high temperature). Foil-coated material is a good idea, it will act as a heat reflective layer.

To create a quality vibration isolation layer is necessary to treat all the planes between the stiffeners. Often there is a need to replace the already installed vibration protection. To do this, you need to order more effective materials online. As a rule, the delivery of the order takes a few days.

To create a second layer, which is responsible for thermal and noise insulation of the vehicle, you can use thermal insulation materials, using a foil layer. It is worth noting that the use of noise-absorbing elements, on the hood will not be as effective. It is better to mount sound reflective materials.

Installation of noise insulation of the roof

Installing noise insulation on the roof of the car is the most necessary step to improve the insulation of the entire interior. This is due to the fact that the roof has no sound protection, and is limited only to the upholstery material. This leads to the fact that the driver and passengers, through the ceiling, can clearly hear the noise of passing cars, wind and rain. Also, the relatively thin layer of metal resonates perfectly with a car speaker system.

Insulation of the roof is also carried out in two steps: the installation of vibration insulation and, directly, the noise insulation itself. To protect against all kinds of vibrations, it is recommended to use a two-millimeter layer of material “Vizomat”. It should cover the space between the ribs of the roof to 80 or 100%. To seal the space between the roof and the roof stiffeners, you can use strips of vibrodampfer.

Why do I need noise insulation?

Car engine compartment isolation is a very popular service, which is ordered by the owners of budget and rather expensive cars. Squeaks and crickets often become the reason for treatment in the technical center, which are especially evident in frosty weather and when driving on rough roads. But of course, after laying the insulation material also reduces the noise and vibrations that are transmitted from the engine compartment. Note that performing these operations involves dismantling the torpedo, which in itself is not the easiest thing to do. Of course, it is important to calculate the thickness of the material laid, because if you make a mistake, the panel installation will be very problematic.

Car engine compartment isolation can be an independent operation or a part of complex works. It is also worth noting that the price of such an event directly depends on the class of the model.

Noise insulation of wheel arches

In medium-class cars, noise insulation of the wheel arches is given little attention. However, it is this part of the vehicle is the most noisy. The sound that occurs when the car is in motion penetrates the interior and interferes with a comfortable ride.

Noise isolation Toyota Corolla includes measures to trim the wheel arches with sound-absorbing material. To do this, each wheel arch is trimmed as the outside of the body, and inside the cabin. On the outside, it is recommended to use vibration-absorbing materials that were used to increase the sound protection of the doors and hood of the vehicle. On the inside, noise-absorbing materials are used. They are processed by the rear wheel arches, the floor of the car, the trunk and the bulkhead of the engine compartment.

Noise isolation of Toyota Corolla 150 and 120 is carried out in several stages: hood, roof, doors, wheel arches, partition of the engine compartment, trunk. Actions aimed at improving the insulation, you need to accurately and carefully, since many parts of the interior trim are made of plastic, which tends to break when handled carelessly. Broken latches do not contribute to a tight fit of this or that part of the car interior, and it significantly spoils the comfort of using the vehicle.
