I Tested And Reviewed 10 Best Sound Deadening Material For Cars (2023)

The 5mm closed cell foam matt self-adhesive with a foil backing is a versatile option for various projects. While it can be a bit challenging to handle due to its larger size, the inclusion of installation tools is a nice bonus. It's important to note that this foam is part of an overall sound insulation system and should be used to reduce airborne noise. To achieve optimal results, ensure there are no gaps or cracks in coverage by placing the foam on the entire roof, door, or other panels.

Although the reviewer used the product differently – to further insulate and soundproof their RV – they were pleased with the results. The foam was easy to work with, thanks to its adhesive backing that securely attaches to surfaces. The quality of the product is commendable, and the reviewer expressed satisfaction with the insulation and soundproofing it provided. They also encourage thinking outside the box for alternative uses of this product.

One aspect that could be seen as both a pro and a con is that the adhesive is slightly weaker. However, it does not leave residue behind, and if needed, the product can be repositioned a couple of times before the adhesive loses its stickiness. In most typical applications, a strong adhesive is not necessary.

The foam itself is soft and has a jelly-like texture, making it ideal for sound absorption. The foil layer also proves effective in reflecting heat. Overall, this product is of high quality and would be beneficial for enhancing sound insulation in classic cars or other applications where stock insulation is lacking.

I recently purchased insulation panels for my vehicle and garage door, and I must say, the results exceeded my expectations. The installation process required a razor, a good pair of scissors, and a fair amount of patience. Cutting out all the tiny holes for trim screws and around wiring proved to be quite tedious. However, in hindsight, I wish I had done all the panels instead of just a few.

I initially bought the insulation panels to reduce the noise in my FJ cruiser, which was incredibly noisy. I noticed an immediate difference after installing the panels on just the driver's door. The rectangles were easy to work with, although I wouldn't recommend trying to use a roll of this material. It's much more manageable in panel form.

One important tip I learned is to avoid exposing the insulation to direct sunlight. It becomes extremely sticky and challenging to work with when heated up. It's best to apply the insulation in colder temperatures. The adhesive material reminded me of asphalt, so I can only imagine how it would react if exposed to fire.

In terms of my garage door, I read in other reviews that full coverage wasn't necessary to achieve good results. This was crucial for me because adding the entire box of insulation would have required re-tensioning the spring to account for the added weight. Instead, I decided to cut up the panels evenly and distribute them in the most noisy spots, including the door, tracks, and opener motor. Despite only using a few panels, the results were phenomenal. My garage door is now quiet enough to open and close at 4 am without waking my neighbors in adjacent bedrooms. I'm so impressed that I plan on using this insulation on everything now!

I recently sound deadened the driver side door of my wife's car and the results were remarkable. The door feels more solid with the added mass and the speaker system sounds much better now. The application process was easy, especially with the use of a metal roller, gloves, and proper cutting tools. The sound deadening material sticks well and does a great job.

I also placed these pads under the floor mats, front and back seats, as well as in the trunk of the car. The highway and tire noise were significantly reduced, making the car much quieter at high speeds. It has made a noticeable difference in the overall driving experience.

I also used this sound deadening material for the inside of my motorcycle fairing to improve the sound quality of the speakers. It was easy to work with and stuck securely. I was initially concerned about heat resistance, so I tested it with a touch lighter and was pleased to see that it did not melt or drip even after being accidentally set on fire. It did puff up slightly and became gummy when touched, but this was after exposing it to more heat than it would ever experience in normal circumstances.

Furthermore, I used this product in my trunk to reduce the loudness of my exhaust. It worked great and effectively dampened the noise. It was easy to work with and adhered well to clean surfaces. The added weight of the sound deadening material is a bonus, as it adds to the overall quality of the product. I used it on various parts of my 2009 Harley Davidson Electra Glide, such as the fairing, lower speaker pods, and saddlebags. It has helped prevent any potential rattling caused by the new custom stereo.

An additional advantage of this sound deadening material is that it is made in Russia, which adds to its appeal. I am highly satisfied with this product and will definitely purchase it again in the future. I would also recommend it to all my friends who are in need of sound deadening solutions. Lastly, the shipping experience was excellent, with the product arriving in a timely manner.

I recently purchased this sound dampening mat for my vehicle and I must say, it exceeded my expectations. Not only does it do a great job of keeping the desired sounds inside the car and blocking out unwanted noise, but it also enhances the overall sound quality of my radio experience. Additionally, it has helped to compensate for the aging sound deadening in my older vehicle.

One of the standout features of this product is its resemblance to dynamats in terms of look, feel, and performance. It easily forms into shape and stays put with its super sticky adhesive. I am yet to test the longevity of the adhesive, but based on my initial experience, I am optimistic about its durability.

The importance of sound dampening cannot be overstated, as it helps prevent rattles, shakes, and excess vibrations that can interfere with your music listening experience or be caused by rough rides in older vehicles. This sound dampening mat is heavy and sticky, ensuring it stays in place once applied. Just make sure to properly smooth it out during installation.

In terms of quality, I found this product to be on par with other sound dampening mats I have used in the past. However, it comes at a fraction of the price, making it a cost-effective choice. Of course, individual experiences may vary.

I was pleasantly surprised by the weight of the product when it arrived. It is as heavy as a brick, which speaks to its durability and effectiveness. Despite its weight, it is thin enough to easily slide behind paneling and carpet without causing bulges. This feature also aids in easy reassembly.

On top of its performance, I appreciate that this sound dampening mat is made in the US and is priced more competitively compared to other options in the market.

I recently purchased this product and was pleasantly surprised by its performance. Contrary to what some others have mentioned, I found it to be easy to work with and not overly sticky. When cutting it with scissors, I was able to do so quickly and without any issues.

I specifically used this product to insulate the seat of my Honda Pioneer 1000-5 from the heat emitted by the exhaust. It worked perfectly for this purpose. The material was easy to cut into the desired shape and install. I made sure to use the largest pieces that I could properly apply, removing the backing carefully.

One thing to note is that once the adhesive sticks, it is very strong and cannot be easily moved. This is important to keep in mind, especially when working in corners or tight spaces. However, as long as you position it correctly the first time, you won't have any problems. Attempting to peel the product up may result in tearing, so it's best to ensure it's in the desired location before placing it.

I also used this product to line a box housing a diesel heater. While removing the backing proved to be a bit challenging, especially if not pulled at the perfect angle, it wasn't a major issue. Some small pieces of backing did get stuck on the mat, but they were manageable and didn't hinder its functionality.

Considering the price, I can't complain about these minor inconveniences. I have used other expensive products like Dynamax Extreme and Dynaliner for similar purposes, but for this particular job, they seemed like an unnecessary expense. Overall, I am satisfied with this product and would recommend it for insulation needs.

I recently purchased the Siless LinerPRO 2in1 200 mil sound deadening material and I am extremely satisfied with the results. I installed it in my car to reduce exhaust noise and it has made my drives much more enjoyable.

The adhesion of this product is excellent and it was easy to install. It is also easy to cut, which is a plus. As long as you clean the mating surface well, this material sticks like a glue trap for mice. It has a strong adhesive that does not let go. Just make sure to leave it in the shade before peeling the adhesive backing off, as direct sunlight can make it super sticky and slightly harder to remove the backing. However, this is not a big deal and keeping it in the shade will make it peel off easily.

I am impressed with the chemical and water resistance of this sound deadening material. It is also visually appealing and looks fantastic once installed. I have used other brands in the past, but this one does it all.

I plan on using this material for several other projects in the future and would like to try out other types to see if there are any differences. It worked well in my 79 MG Midget, and I would highly recommend it to others.

I purchased two boxes of the 36sqft 200mil Siless pro, and it is definitely going to help me transform my old Dodge Cummins into a nice cruiser. I may need to buy another box to complete all the areas I want to cover, including the ceiling.

If you have an older car or one that lacks noise insulation, or if you simply want to improve the quality of your ride, adding sound deadening material like the Siless LinerPRO 2in1 200 mil is a great solution. Unlike some other sound deadeners, this product not only provides a butyl layer for reducing vibrations and road noise but also includes closed cell foam for added insulation.

The butyl layer effectively reduces road noise by blocking out vibrations from panels, tires, wheels, and suspension parts. This is particularly noticeable on roads with many imperfections, where vibrations tend to seep into the cabin. The Siless LinerPRO 2in1 goes beyond just reducing noise, as it also adds a layer of insulation that helps maintain consistent vehicle temperature. It blocks out heat when it's warm outside and keeps the car warmer when it's cooler outside.

With this product, you have the convenience of a 2 in 1 solution. Instead of applying separate layers of butyl and closed cell foam, you can simply install the Siless LinerPRO 2in1 and enjoy the benefits of both. I have personally installed this in my VW GTI's trunk floor, and the overall driving experience has improved significantly. There is noticeably less road noise, and I feel more isolated from the road.

With 36 square feet of material, I was able to cover my trunk floor, door panels, and possibly even the area under the seats. However, the amount needed may vary for larger cars. While I may not go as far as covering the seats, I am eager to improve the door panels.

I recently had the opportunity to use this product on my NB Miata 2001 and I must say, I am extremely impressed. Living in Guatemala, where the weather is tropical and hot, my car's cabin would often become unbearably hot, especially during long drives. However, after using this product, I noticed a significant difference in cabin temperature. The heat has been reduced, making my driving experience much more comfortable.

The application process was easy and straightforward. I followed the instructions and had no issues with the paper coming out unevenly, which some other reviews had mentioned. The trim tools provided were of good quality and helped me during the installation process. I did have to remove my dash, which was a lot of work, but the end results were well worth it.

Not only did this product help with heat reduction, but it also helped in reducing road noise. While it may not completely eliminate the noise like in a luxury BMW, there was a noticeable improvement. It made my driving experience quieter and more enjoyable.

I also had the opportunity to use this product on my 14-year-old Evaporative Cooler. The cooler was becoming increasingly loud, making it difficult to sleep on hot nights. After trying various repairs, I decided to give this product a try. I was amazed at the results. The noise reduction was significant, and it made sleeping much easier. The insulating properties of the product also improved the cooler's efficiency, resulting in cooler air in a shorter amount of time.

The application process for the cooler was a bit more time-consuming, but it was well worth the effort. The product was flexible, allowing me to fill gaps without precision cutting. However, it is important to note that once it is firmly attached, it cannot be easily lifted without tearing it. So, it is essential to start with small sections and learn from the process.

This sound deadening material truly lives up to its claims and performs as advertised. I recently installed it in the rear hatch area of my 84 Corvette, and the difference in sound quality is remarkable. Previously, even light tapping on the surface would result in a drum-like sound, but after the installation, the tone has significantly lowered. I used 5 and a half sheets for this area alone and plan to continue using the rest of the material for the doors, floors, and trans tunnel.

In another vehicle, an Acura RDX, I used two packs of this sound deadening material and was able to reduce the sound pressure level by 10 dB (A weighting) at 70 MPH on coarse roads. This improvement was clearly noticeable and made for a quieter ride, as well as enhanced music listening experience. To achieve this level of noise reduction, I covered all four doors, the rear hatch, the spare tire area, the floor, and the wheel wells. While it did require a significant amount of work, the results were definitely worth it.

What I appreciate about this sound deadening material is that it is relatively easy to work with. It adheres well to any clean metal surface, even curved areas, as long as the bends are not too sharp. The first two packs I used were black and seemed to have better sticking power compared to the third pack I purchased, which was silver. However, overall, I still highly recommend this product as a reliable and cost-effective sound deadening solution.

Additionally, the density of this material is impressive considering its thickness. It easily conforms to the desired shape, and I found that using a heat gun while rolling it made the installation process even easier. It is also incredibly sticky, ensuring a secure and long-lasting bond. I used this material in my 92 K1500 truck, which was previously plagued with rattling and flexing whenever I played music. After applying it to problem areas such as the roof, inner door skins, and rear wall of the cab, the difference was astonishing. The sound is now solid, and there is significantly less exterior and road noise, even with a 3" exhaust and super 10 mufflers installed. I will be reinstalling my stereo equipment soon and will update my review to provide feedback on the improvements in that aspect as well.

The Siless Liner 157 mil (4 mm) Sound Deadening mat is a highly effective product for reducing unwanted noise in your car. While it can make a noticeable difference on its own, combining it with traditional butyl rubber sound-deadening materials will take your sound deadening efforts to the next level.

The reviewer, who owns a Honda S2000 convertible sports car, shares their experience of installing both the butyl rubber and the Siless Liner. They first installed the butyl rubber on the car's interior sheet metal, covering as much surface area as possible. They were impressed with the results but wanted to further improve sound deadening.

Next, they added the Siless Liner on top of the butyl rubber, covering every area where the butyl rubber was applied. They even used the Siless Liner in areas where butyl rubber wouldn't have been effective, such as the roll bar hoop area and large empty cavities or holes. The reviewer was amazed by the results.

With the combined use of the butyl rubber and the Siless Liner, they were able to have conversations with passengers at normal-ish volumes and make hands-free phone calls without blocking out the noise. The sound system also sounded much better. The reviewer emphasizes the importance of looking for any vibration, rattle, squeak, and noise-prone areas during the installation process to eliminate or reduce unwanted noise production.

They also mention that the Siless Liner works both ways, reducing noise from inside the car and preventing sound from escaping outside. The reviewer notes that even when playing music at high volumes in their garage, the noise is barely noticeable from the outside.

To make the installation process easier, the reviewer recommends getting a 3 piece wood/metal roller set, which helps with applying the mats to large areas.

I found the adhesive qualities of this product to be impressive. I used it to line the sub saddlebag box of my 2004 Honda VTX 1300, and it provided a low, deep, and solid beat while also effectively killing sound waves in the sub box. I was thoroughly impressed and will definitely purchase it again.

Additionally, I utilized this product to insulate and reduce noise in the inside of my RV rooftop AC units. After watching instructional videos on how to apply it, I ordered this product and found it to be perfect for the job. I highly recommend it for this purpose.

Contrary to some reviews, I did not experience any difficulty cutting the material. I simply measured the pieces I needed and effortlessly cut them with a pocket knife. The thickness of the material, combined with its strong adhesive properties, left me with no complaints. I will certainly purchase it again for my future projects.

While the material is lightweight, the 10mm thickness proved to be sufficient for lining the freedom top of my 2008 Jeep, effectively reducing heat and keeping it cooler. The adhesive sticks well to any surface. However, it is worth noting that the aluminum facing is slightly wavy, lacking the flat and smooth finish I had hoped for. On the positive side, it accepts plastic paint without flaking off.
