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.

Great sticky power and great insulation

Love the product, have it in my cargo ven the entire area , works great as described, sticks very well, after one year of trying more doing my camper shell. Worth the price, hope they don't increase it

I like it

Easy to work with. The adhesive is sticky, duh. But what I mean is it's difficult to cut with scissors and sticks to fingers. It comes off by rubbing them on a cloth. Seems to stay adhered to walls and metals. I found it pretty satisfactory.

Works great

We bought this to insulate our cargo van roof. The roof has so many angles and dips. This molded over everything perfectly. You have to be very careful because once you touch it to the metal it's done. You cannot get it off without tearing it. We found we needed two careful people to get it on right. I gave it 4 stars because it would nice if it was thicker or we had the option to buy a thicker product. Also, when we ordered it, we didn't notice that the last photo had advertising on the surface and we were going to return it (I do not want to look at advertising), but then we received it and it did not have advertising on the surface after all. It's easy to cut with scissors or straight edge and a ruler. If you push down and don't stretch it, it does not tear. It is thin moldable foam with a strong adhesive. Here's some pictures of what we did. We plan to cover the roof with wood slats or something similar. We did it for the sound deadening, but also for a small layer of insulation on the ceiling of our van. It was really difficult to find a product to put up there and this worked!

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.
