VOISEN Sound Deadener for Cars, 157 MIL (4 mm) 36 sqft Sound Deadening Mat,Car Sound Deadening Closed Cell Foam & Heat Insulation Mat - PE Foam Sound Deadener Material & Heat Barrier

Excellent service.

Why did you pick this product vs others?: I’ve used several sound deadening materials over the years — from Noico to Siless — and honestly, this one surprised me. I used it inside my doors and rear panels during a full audio upgrade on my truck, and it made a noticeable difference in road noise and vibration control. What really stood out was how well it sticks. Compared to Siless foam, this adhered way better, especially on slightly curved or uneven metal surfaces. I didn’t have to fight with it or go back and re-press areas — once it was down, it stayed down. Installation was easy with a roller and a heat gun for tighter spots. It's also noticeably cheaper than some of the name-brand options, which is great when you're trying to cover a whole vehicle without spending a fortune. Pros: ✅ Excellent adhesion — better than Siless in my experience ✅ Reduces road noise and vibration effectively ✅ Flexible and easy to work with ✅ Great value for the price Cons: ⚠️ Backing paper can tear if you rush the peel (go slow) ⚠️ Doesn't have brand hype — but still performs like a premium option

Definitely helping with making my sound system sound better in a lexus 08 es350

Purchased to wrap some areas of the duct work in my house to help with the transition of sound from the basement throughout the rest of the house. While not perfect, it does make a noted decrease in volume and clarity of sound that gets echoed through our ducts and that's all I needed it to be able to do! The adhesive works great and application was very easy. The material isn't too heavy to work with and light enough to stick upside down without sagging or pulling off an aluminum duct. And was easy enough to trim with a razor blade and scissors (although the scissors needed to be cleaned to remove the adhesive residue afterwards) If you need sound dampening/deadening material, this one hundred percent does the job. Combine it with open cell sound foam and it makes a space both quieter and with less sound transmission to adjacent rooms.

No noticeable difference
