Product Description

Automobile Insulation car auto
Trunk Soundproofing materials

reduce noise

Reduce noise and vibration

Improve the sound insulation performance of the car, reduce the noise inside the car, so that the driver and passengers get a more quiet and comfortable environment.

Hood absorption sound mats isolate noise and vibration

Slow down hood paint aging

The temperature in the engine compartment will rise after driving, accelerating the aging and cracking of the hood paint, while the sound insulation material can well slow down the aging of the paint and isolate the noise and temperature of the hood.

Fireproof and waterproof

Flame retardant and waterproof

The sound insulation foam is flame retardant and reduces the entry of external temperature. The aluminum outer layer is waterproof and prevents rust and corrosion of metal parts inside the car.

Modification of car audio sound insulation materials

Make the car audio play better

The energy of the speaker triggers the resonance of the car when it reverberates in the door, acoustic insulation absorbs vibration and noise. When that stops the speaker projects better with more clarity, perfect for use when modifying car audio.

    Reviewed in the United States on February 15, 2024
    Style: 197mil/15 pcs(16.3sqft)Verified Purchase
    These were perfect for what I needed them for. I have a Honda Fit that, by the factory, has near no sound insulation and is terribly loud when driving down the road. These were thick enough to be effective but not so thick that it kept my interior trip panels, headliner and console from obstructing them from going back on. The pill-and-stick feature was easy and fast. The paper backing was not only easy to remove but gave a surface to draw on when transferring over a pattern to cut out. Plus, they cut super easy with a good pair of all-purpose scissors, not once clogging up the blades with adhesive residue. The adhesion also seemed super strong even on the underside of my roof sheet metal. After using these over a good portion of the inside of my car, concentrating above the exhaust, the firewall and the roof sheet metal, my car is not only much quieter, but it now also gives the impression of a more solid driving car. I wasn't expecting that and it was a bonus. If you have the knowhow and time to take apart an interior to get to the car's interior sheet metal. I highly recommend these stick-on insulators. But I cant give feedback on engine compartment or outside of the interior use. I have no experience if they'll hold up to direct heat or moisture.,...

    For what I used them for.... 5-stars all the way

    Be careful when handling because If the adhesive sticks to your fingers or anything else it will pull some of the foam off. Used inside of plastic speaker pods to make them sound less hollow but I'm not sure how they would hold up to any other application which may be more demanding.

    This does nothing to affect sound damping. I recorded the sound of knocking on the side of my car door and it made no difference. Too late to return it, so I guess I'll use it for padding for something.
