Siless 80 mil 5 sqft Car Sound Deadening mat - Butyl Automotive Sound Deadener - Noise Insulation and Vibration Dampening Material

Product works for what it's designed for but I will say it is a lot messier than some of the other brands of sound deadening I've used! It sticks well but it seems to become a lot more soft and tacky in the heat compared to other brands! Great value if you're on a budget! It does have an odor kind of like a kind of asphalt tar smell but it goes away after a couple days. Decent quality for the price and the thickness is as advertised. Sticks on easy so installation is a breeze and it's easy to cut which is great!

This is an excellent product. Easily moldable, cuttable with good scissors or razor knife, very sticky, works great. This pack was enough to do all 4 doors on a crew max truck, and I went wild on the fronts. I used 9 peices on each rear door which was just enough, and the rest on the fronts. I doubled up layers and even used some on the back of the door panels. If you follow the instructions and dont go wild you might even have extra left over. It works just like you would imagine. Without doing the entire cab there will still be road noise but this helped noise, better audio, no buzzing door panels, terrific improvement. It is kind of heavy, so extra weight is added to truck, but that really isnt a bad thing. It is noticable but in a good way. Get it. Use it.

Have used several times. Easy to work with and does the job.

Worked GREAT! Big difference on the sound of the interior. Applies easily.

I read everything I could in every brand of this product. I have no experience in use of others in market. However this product performed exceptionally well in all area's of my concern. Adhesion biggest factor. Ease of install exceeded my expectations. Sound deadening? It did stop cross beam noise that were just glued to stop noise from manufacturer. Heat resistant is a good word for this product. I installed product in vehicles doors. Then went shopping. Came back to car full sun side door aluminum shield was very hot. However non other on market could prove different about their products. As far as odor the product delivered on quality of backing being no odor. Even with heat on door. No odor. ( No I do not have Covid) Overall very satisfied the amount to do my project pretty much matched the manufacturers suggestions in ordering product. I also purchased the sound deadening waterproof foam as a top dress. I used the heat shield and covered with the foam in roof of vehicle. That did make a difference in sound deadening and once headliner is reinstalled I believe it will buffer hear from outside a bit. This product as heat shield in my opinion would be more effective and added benifit to snow and cold country at trapping heat inside vehicle. I gave it less stars as I have no comparison to other products. I am thinking on ordering more . I also used it in place of undercoating in tough area's see what happens as it wears. It definately sticks to clean surfaces.

I purchased this to insulate and quiet the large compartment on my motorhome that served as a echo chamber while driving. It is easy to install, and the roller evens out the seams. Definitely a game changer if you are looking for insulation and want to reduce noise. I have now found additional uses for it. Namely, to quiet the inside of my side-by-side.

Let me start of by saying WOW! This made a huge difference in the SQ of my L7S pushing 930w rms. Before I had major rattles in my 2020 Honda Civic SI. Taking the time to do this to my trunk and Lid made me realize just how loud my subwoofer actually is. It literally eliminated the rattles throughout my whole car. I still plan on doing this to my doors and rear deck but once I upgrade the speakers. I still have half of the box just doing the trunk and lid so 1 box of 36sf will be enough for most of the areas that need to get done. You may need a little more overall. This is true 2mm spec. Very sticky and easy to apply. It just take time to finish the work correctly and roll it down. It is not as heavy as I thought it was going to be. The size of the sheets are perfect for what you need to do. The value is on point for the quality. It does not rip very easily but you can cut it to size without any problems. Again, This is a must buy for anyone who is pushing 1000w rms or more.

Worked great!

Seems to work well - as advertised

Quedo bien beuna calidad, fácil de instalar

Tried to sell a lower quality product compared to the description

Good adhesion, easy to use. It dampens vibrations well, but you also need sound deadening foam. One package was enough to completely cover four doors.

Not really worth it. Very little difference in noisec reduction.
