Exactly what i needed!
I recently purchased the Siless Liner 314 mil 18 sqft Sound Deadening mat and I am absolutely thrilled with the results. This product is a game-changer when it comes to reducing noise and improving the overall sound quality in my vehicle. The 314 mil thickness provides excellent sound insulation, effectively blocking out road noise, engine noise, and vibrations. One of the things that really impressed me about the Siless Liner is the price. Compared to other sound deadening products on the market, this one is incredibly affordable. I was a bit skeptical at first because of the low price, but after installing it in my car, I can confidently say that it is worth every penny. The quality of the material is top-notch, and it is easy to work with during the installation process. Not only does the Siless Liner effectively reduce noise, but it also helps to improve the overall sound quality in my vehicle. The sound deadening material creates a more acoustically pleasing environment, allowing me to enjoy my music and conversations without any distractions. I have noticed a significant difference in the clarity and depth of the sound in my car since installing the Siless Liner. Overall, I highly recommend the Siless Liner 314 mil 18 sqft Sound Deadening mat to anyone looking to improve the sound quality in their vehicle. It is a cost-effective solution that delivers exceptional results. Don't let the affordable price tag fool you - this product is a game-changer when it comes to reducing noise and enhancing the overall driving experience.

Bringing a 1976 MG Midget to the modern world!
I've been restoring a 1976 MG Midget barn find. I bought some Sinless liner to help make the car rattle less and feel more solid. This product is easy to cut, easy to install, and extremely sticky. I used it to line the trunk, the interior, and even some under the hood of the old MG. The adhesive stands up to the brutal temperature of the engine bay, and when (by accident) some fuel spilled onto the foam, it didn't fall apart or turn to mush. Thanks to Siless, the MG now feels like a modern car. The floor pans feel much more solid, the doors make a heftier thud when you close them, and the trunk no longer sounds like a percussion instrument when you touch it. If you know what you're doing, this product will transform the feel of a car. I found that 36 sq ft was enough for my MG Midget, but for a bigger car I would want more. The pattern on the back helped me to cut perfectly measured squares and rectangles. The foam itself doesn't have a strong odor, it works super well, and has held up to several months of changing temperatures (in the Midwest US.)

Better than Kilmat
Great adhesion, and you can immediately see the sound difference when you rap the area and compared it to another area without it. Also, very easy to cut and apply. Once on, you may not be able to peel it and reposition it, so be sure where you want it.

Its ok, it makes a SLIGHT difference in sound, heat insulation is subpar and mostly unnoticeable.
It works OK, could be better. The heat insulation is subpar, it needs several layers to make an actual difference. It is very lightweight but it needs more heft in my opinion. It looks like regular foam once installed nothing fancy, a bit shiny. It does scuff fairly easy, so be careful with whatever roller you use. It doesnt have any weird smell like butyl does or anything like that, it is OK value for the money, I expected a bit heavier material but it does the trick, have some very slight vibration reduction but nothing noticeable until a few layers are put down. You can get quite a large roll so it does cover a lot of space. I did wish they offered a wider version.

Works amazingly, but only if you install it correctly.
If you purchasing Siless Liner 157 mil (4 mm) Sound Deadening mat, to block unwanted sounds in your car, this is what you need to buy. But wait! It's not the only thing you need to buy if you want to "actually" deaden sound. By itself, it will definitely block a noticeable amount of sound, and, most likely, that's all you realistically need. But... But... If you want the Siless Liner Sound Deadening Mat to really help you take it up a few notches, to get the best sound almost bordering on soundproofing, listen up. You will have to install traditional butyl rubber first. Doesn't have to be the Siless brand, but I'm sure they would love to sell both to you, I used both Killmat (80mil) and Noico (50mil). I have a Honda S2000. It's a two-seater convertible sports car if you don't know what this car is, and it's loud when I'm driving above 60mph. I also happen to have a sound system installed as well. Other than that, the car is stock. I first installed the butyl rubber on the car's interior sheet metal. I went all out and covered everything I could. I didn't need to but I wanted to. I was extremely impressed with the results. But I wanted to go further. Not because I needed to but because just wanted to see what it would be like. So I bought Siless Liner 157 mil (4 mm) 36sqft Sound Deadening mat to go on top of the butyl rubber mats. I put this over every area I installed the butyl rubber. I had to be careful of clearance issues since I added a significant amount of underlayment, and you should too. If you put butyl rubber sound-deadening materials in 50% of the total interior area, you'll hear a noticeable improvement. If you put butyl in about 80% of the total area, you'll be even more amazed at the improvement, compared to before. I originally did all the above myself, so that's my experience and so your mileage may vary. I then installed the Siless Liner Sound Deadening mat over every place I could even going further than I could with the butyl rubber. I used the Siles Liner in areas where butyl rubber would not have been effective, such as the roll bar hoop area and large empty cavities or holes. I covered everything I could, firewall, doors, floor pan, transmission tunnel, trunk, trunk lid, fuel tank area, rear quarter panels, and rear-wheel tunnels, in Siless Liner Sound Deadening Mat. WOW!! The Siless Liner Sound Deadening Mat was the icing on the cake! Let's not forget, this car is a convertible sports car so it will never be a quiet ride, ever. But I can now actually have a conversation with a passenger at a normal-ish volume! This also means I can now have a normal hands-free phone call without having to plug one ear to block out the noise! My sound system sounds so much better! Just by going through the install process, I looked for any vibration, rattle, squeak, and noise-prone areas to either eliminate or reduce unwanted noise production. If you forget this step, the inside and outside of your car will rattle and buzz. I skipped this step the first time around. But did it right before I installed more butyl rubber and the improvement was impressive, especially inside the car. Outside the car, I didn't notice a difference until I put the last layer of Siless Liner Sound Deadening Mat. The sound deadening mat works both ways from what I can tell. If I turned up my music, as loud as I occasionally do, parked in the attached garage to the house, with the garage door closed, I would be barely able to tell the car was playing music in the garage. It sounds like it is another car, just a little bit down the street, with a very loud base. If you stand 20 feet away outside the car, the sound system is noticeable, but not obnoxious by a long shot. Get a 3 piece wood/metal roller set as well, which makes quick work of large areas.

Adheres very well, but scuffs very easy
Scuffs really easily. Just a bandaid on my finger while running it along the ends where they meet to seal up made a mark on it. Adhesion is very good.

Si buscas reducir la resonancia de la lamina debes usar primero caucho butilo y despues agregarle esta espuma encima para mejores resultados. Cumple perfectamente con su funcion que es aislar y sellar paneles, al sellar puertas mejora la acustica de los altavoces, evita vibraciones y ruidos si se usa como empaque o junta al montarlos, el adhesivo es muy fuerte, se pega excelente y es dificil removerlo, no desprende olor alguno aun con el coche cerrado todo el dia bajo el sol a 38 grados.
