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

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

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.

Be sure you know where you are placing this, because the adhesive is REALLY good! This material is easy to work with and does the job fabulously. It doesn't seem like it would hold up to heat well so keep away from engine compartment. I used it inside all my doors and trunk lid to keep noise and vibration down.

Great Value and Noticeable Noise Reduction Reviewed in the United States on October 5, 2025 I used the VOISEN 157 MIL sound deadening mat on my truck cab and doors, and the difference was immediately noticeable. Road noise, vibration, and rattles dropped a lot — especially on the highway and when towing. The cabin feels tighter and more solid, and even my audio system sounds cleaner with better bass response. The material itself is thick and flexible enough to mold around corners and contours, and the adhesive backing sticks very well once pressed down with a roller. It feels just as solid as some of the bigger-name brands I’ve used but for a fraction of the cost. My only small complaint is that the foil layer can tear if you’re not careful when cutting or repositioning, and the adhesive gets messy on hotter days, so wear gloves and plan your layout before sticking it down. Also, it’s a little heavy once installed — but that’s expected at 4 mm thickness. Overall, this is a great mid-priced sound deadener that performs far above what I expected. If you want a quieter ride or better-sounding audio setup without spending a fortune, this VOISEN mat is a solid choice. Would buy again — 4 stars

Honestly this is the best bang for your buck. Adhesive sticks, easy to apply (fits in the car nicely, easy to cut), and it is quite durable. After putting on a deadener (that must be the first layer for cars!), this is both a great sound insulator and decent thermal insulator. Good thickness, was defintely as adverstised. It resulted in a noticable decrease of sound (works well). Don't waste your money on other stuff.

Excellent service.

It is a very good product with many applications

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

This product wasn’t my favourite after using several sound proofing products for my car sound proofing project. I found that the material was pretty rigid and required a very flat surface to adhere to. It was great for flat panels but I noticed that when adhered to contoured panels, the material would later lift and unstick in certain areas. I would recommend a product with a butyl rubber adhesive instead.

Super easy to work with
