Hello. The structural parts of automobile sound insulation are generally: 1. Four doors and two floors 2. Chassis 3. Trunk 4. Hood 5. The more demanding fender also includes a firewall and a rear cover. . . Among them, four doors and two floors are the most important. Because the door is the largest four single metal vibration surfaces in the car body. However, it is generally recommended to mainly use the material of Rongmao Top Sound Insulation King, which is composed of butyl rubber and aluminum foil board. Sound insulation is waterproof, shockproof, heat preservation and flame retardant. If it is sound-insulating cotton, it has a certain sound-absorbing effect. However, if it comes into contact with water vapor, it will be difficult to dry in the car body, which will cause odor inside the car and rust the car body. I hope my answer can help you.
