VOISEN Sound Deading Material for Cars,157 mil 36 sqft Sound Deadening Mat

The product is of good quality and is true closed cell foam. see my pictures for the thickness. I am installing in my doors and trunk for car stereo. I think it is the best value for the money and the coverage of 36 square feet is amazing! the size is 1 long roll which you can cut to shape any way you need which is good. Installation is a breeze with the sticky backing to it. it makes the install go much faster then having to use your own adhesive. this is decent for noise level but is made for vibrations decoupling to stop rattles from bass. you could paur it with butyl sound deadener and you would have a really quiet cabin! I'm sure the noise level would be quieter just with this, but I'm using it to help stop resonant vibration of plastic trim pieces and smooth out my subwoofers bass. I am also installing butyl sound deadener on the main metal. 50% butyl coverage on metal, 60-70% coverage on inner plastic trim panels as well as the bottom of my false floor and also on top of my butyl pieces as a dual install. this will stop all flexing as well as help with cabin gain and make the interior quiet and your doors won't sound hollow when you shut them. This does also help some with outside ambient noise when used in tandum with the butyl. I'll use 50-72 square feet of this for my glb250 and the same for butyl. for the quality and money you cannot go wrong. you will be extremely happy.

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

The sound deading material holds to curves well. It sticks to the bare/painted metal of a 30 year old vehicle well. I used it to cover the back hatch of a xj along with the wheel well areas and the back hatch and I still have several feet that I intend on putting on the floor boards when I pull that carpet up later. Since I had the cat stolen from me... The jeep is loud and this helped calm down the noise in the cab so I can hear things again. Without a decibel meter I cannot tell you how much the reduction was but... The rattle from the back and the feel in the seat is better. There will need to be more put in to fully help. This was the cheapest material I could find for the size, it works well and covers quite a bit of area. I would buy it again and I probably will when I pull the headliner down. As for heat, summer is coming and I am hoping this helps keep the back cooler. We will see what happens. My goal with the jeep is to build a nice daily driver for a cheap as I can, think low car, so far I am doing pretty well at that.

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

I USED THIS IN COMBINATION WITH AMAZON BASICS SOUND DEADENING IN A 4RUNNER. HUGE DIFFERENCE, SPEAKERS SOUND BETTER, ROAD NOISE IN GREATLY REDUCED, AND NOW THE DOORS CLOSE WITH A QUIET DULL THUMP INSTEAD OF THE LOUD HOLLOW RINGING SOUND TYPICAL OF 4RUNNERS. WAS EASY TO INSTALL AND CUT TO SIZE AND SHAPE, HIGHY RECOMMEND.

I used this foam on top of the Amazon basics sound deadening material and I must say there is quite a difference in both sound temperature insulation 5 stars and will buy again

Product Name or Manufacturer: VOISEN Product Description:Sound Deadening Mat w/Adhesive Key Features: 36 square feet; 3-layer sound deadener; Blocks radiant heat; Sound proofing; Water proof; Convenient to install; Flexible and odorless. Product as Arrived: Single roll (16 inches by 330 inches), rolled up in the item's original cardboard box. Positive Attributes: Roughly $1.10 per square foot; Sound proofing; Sound deadening; Easy to cut and install; Good adhesive; Added insulation. Negative Attributes: Durability. Overall Impression: I was searching for an inexpensive way to reduce road noise inside my vehicle’s trunk. I have used other sound deadeners for projects, those being the high-density sound deadeners. This is a closed-foam material, basically like lining the trunk with a thin yoga mat, not butyl rubber. I knew what I was looking for, and this was exactly that. The material was easy to size, cut and contour to the trunk walls. The roll of 36 feet was enough to do the trunk floor and side walls, which is all I needed. I literally had a tiny square. The car specs were around 26 feet, so I am glad I had enough. I would have been extremely upset if I had to take everything apart again! I don’t know how well of an insulator the material is, the listing says “blocks 98% of radiant heat”, whatever that actually means, I am not sure, but it has got to reduce heat gain and loss, at least a little bit. If you are looking for a sound deadener for your car stereo, this would definitely not be my first choice. This material works good for reducing road noise, vibrations and rattles, but not for increasing SPL like the other material. I would definitely think about the project and the desired results before making this purchase so as to properly manage expectations. I paid roughly $1.33 per square foot of the other material. If I were to do it again, I would spend the extra $7.20 (per 36 square feet) for the heavier-duty material. * = Product does NOT function correctly!

Purchased for sound deadening purposes in my sports car as I was upgrading door speakers. It did a great job and definitely made a difference for sound reproduction and road noise deadening.

Super easy to work with

Le produit est agréable à utiliser, l'adhésif est robuste, bravo.
