Soundproofing the roof of the car helps to significantly reduce the noise level in the cabin. To do this, it must be made using the right materials and technology. We will figure out whether you need soundproofing of this zone, and what nuances you need to take into account when performing it.
Why do you need roof insulation?
At first glance, soundproofing the roof of a car does not seem to be a paramount task - the site does not belong to the main sources of noise penetration. Actually this one is not.
The roof is a flat metal element without stiffeners. It resonates to the beat of vibrations when driving on uneven surfaces. Due to the specifics of the aerodynamics of the machine, the air flow is located in a horizontal plane. The area of this area is significant.
The upper part of the machine in the warm season becomes a source of high temperatures. In cold weather, on the contrary, it is a source of heat outflow.
Another important factor is precipitation. Noise from hail or rain drops significantly reduces the acoustic comfort inside the cabin.
Efficient soundproofing of the roof of the car leads to: a decrease in the overall background noise of the cabin when driving on uneven road surfaces, strengthening the body when overcoming bumps and normalizing the temperature balance.
What materials are needed
Before the beginning soundproofing of the roof is carried out preparatory work. It is advisable to contact a certified installation center: experienced craftsmen know how to avoid damage to the skin. For soundproofing, materials with different properties are used:
- The first layer is vibration isolation. It is tightly glued to the metal surface and rolled with a roller.
- The next layer is sound and heat insulating. It helps to avoid the formation of condensation in the warm season. The layer is made of materials based on foamed polyethylene or foamed rubber. Installation is carried out over the entire surface.
- The third layer is noise-absorbing material. Blocks the propagation of sound waves.
To avoid the appearance of a creak, plastic elements and wiring are treated with special anti-creak materials. Processing is carried out in places of attachment to the body. These are special woven or non-woven materials that limit the movement of plastic elements, eliminating the appearance of unnecessary sounds.
Be sure to consider these points before ordering soundproofing. It is better to check with the masters how such retrofitting is carried out in order to gain confidence in the quality result.
