Siless 80 mil (2mm) Car Sound Deadening mat - Butyl Automotive Sound Deadener - Noise Insulation and Vibration Dampening Material 5 sqft (0.46 sqm)

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!

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.

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.

Works great sticks even better easy product to work with definitely buy it again

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.

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

I installed this product in the doors of my 2006 Mazda MX-5. Do they reduce road noise? Probably, but the reduction by just doing the vehicles' doors is minimal. BUT noise reduction was not my goal.Improving the radio performance and sound quality was my goal. The sound deadening instalation does change the sound. The aftermarket system is a Sony AX5600 head unit, door speaker are Kickers KS 5x8. Kicker HS8 subwoofer behind the passenger seat.The sound: The highs will be less tiny and maybe not as loud. The middle tones impoved in clarity and are easier to hear. The singers voice does sound better and more seperated from instuments. The bass distortion is less. The bass hits hard, but the low end rumble of the bass is reduced. Noise vibration from the door is greatly improved. I adjusted the subwoofer to address the loss of low end bass rumble.The overall sound quality did improve. Plan to have about two hours per door for installation. This includes disassembling the door, cleaning the door interior and installing the sound deadening material. There are videos on YouTube. Watch a video for tools needed and if you are up to the door disassembly process. I would do it again, because I have an ear for detail and quality sound. The second reason I'd do it again is it only costs me $30.00 and about 4 hours in the garage on a hot day. I used 10 square feet of sound deadening material for both doors (19 sheets)If your goals is to reduce road noise. My understanding is the wheel wells is where you should start. I don't have experience with this installation, but there are videos on YouTube.Good luck.

I purchased 10 sqft of Siless sound deadening mat to use on my 2016 Honda Fit LX. Being the base model of the cheapest car in Honda's lineup, you definitely know they skimped on the sound insulation.After removing the interior panels in the car, I applied the Siless mat directly to the sheet metal of the spare tire well, the tailgate, and each of the four doors with about 25% coverage evenly distributed as possible. The 10 sqft was just enough to complete the job. I went with 25% coverage since that's all that's needed to dampen the vibration from each of the areas.The mat itself was really easy to work with and cut to size. Having a roller definitely helps, but don't sweat it if you don't have one. I pressed the sheets into place with the palm of my hand inside places that were too tight for a roller to work in.The materials were applied to my car with the ambient temperatures near 90F. This made the butyl materials a bit goopy and challenging to peel back the backing paper. Having gloves on definitely helped when working with this stuff as the butyl can smear all over your hands.The difference the Siless mat made to the road noise inside the little Honda was night and day! The car rides much quieter now. For less than $30, this was a worthwhile purchase to add a little comfort to the car, and it only took a few hours to put everything together!
