A: Yes, Closed-cell Foam reduces road noise through:1.Sound absorption (energy to heat conversion) 2.Acoustic impedance reflection 3.Mass law blocking of mid-high frequencies. Its structure effectively reduces road/wind noise transmission into cabin.

**Q: Does it require any special tools for the installation? Is a roller necessary?**
A: Basic tools: gloves, utility knife, measuring tape. A roller (sold separately) is highly recommended to ensure proper adhesion of butyl/foam. Aluminum foil tape is essential for sealing seams. Keeping surfaces clean is crucial for optimal results.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Works as advertised, but does have a different texture compared to other closed cell foams
*by A***N on June 3, 2025*

This particular foam insulation was more stretchy compared to other brands which made it easier to wrap around the bumps on the car door. The texture and feel of this foam is more neoprene and less like a camping/yoga mat. The backing is sticky enough to adhere to the door's surface but you cant heat it up a little bit to get the glue to be more sticky if you need.For this to work as a "sound deadener", make sure to also use some sort of butyl rubber as the first layer. This foam alone won't help with the vibrations caused by the wind on the door panels, it just absorbs some of the sound waves.

### ⭐⭐⭐⭐⭐ Worked great for mechanical keyboard customization.
*by B***E on June 10, 2025*

Great soundproofing material for keyboard customization. Cheap and the adhesive seems pretty good. Did a great job of making my keyboard more "thocky", if that is the sound you are looking for.

### ⭐⭐⭐⭐ Works well in bathroom wall
*by W***A on April 27, 2025*

This sound foam made a significant difference in the noise from upstairs plumbing pipes. It was easy to install and with a couple of layers, it's really reduced the sound of water. I'm happy with it.
