I was surprised by how good the adhesive is. The backing paper has sq inch measurements so it’s very easy to cut to size. I used a cheap paper cutter from Walmart to get a straight cut.
I used it for the headliner, door panels and for sealing gaps.
Remember this is closed cell foam so it’s really not for sound proofing rather to stop rattles and vibrations, if you use it for what it is you will be pleased.

Good job when used for soundproofing overhead garage doors in home workshop.

Reviewed in the United States on March 22, 2024

Size: 36 sqftVerified Purchase

This product, in conjunction with rockwool and door edge gap sealing strips made a big difference in reducing the sound from my garage workshop so my work won't disturb the neighborhood. This by itself will not be sufficient but does help absorb lower frequency sound while the rockwool and edge gap treatment worked with higher frequency sounds. I installed this on the metal of the back of the overhead door, then applied spray adhesive over that to hold the rockwool in place. I used z shaped foam to cover the gaps around the edges of the doors and this eliminated most of the noise and made a big difference in reducing how much noise was emanating from the garage. It was very easy to install.

This product seems like it will work good as an under-layment. I mean, apply it to the dry wall then install an accent type wall over it. That is my next move. I did help but not much. I understand this is meant for automotive so keep that in mind. I am using it outside of its intent. With that being said, boy, it is STICKY and when a quarter size area sticks to your wall (or whatever) you're stuck lol. If you try to remove it, it will just tear. I suggest two people for install. I am being creative with it, so take it for whats its worth.

Works amazingly, but only if you install it correctly.

Reviewed in the United States on December 23, 2021

Size: 36 sqftVerified Purchase

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.

once stuck they stay stuck!

Reviewed in the United States on February 21, 2024

Size: 51 sqftVerified Purchase

We are converting a mini van to a weekend camper & used these as 2 layers on the floor for insulation & noise reduction after removing the seats. They stick REALLY well and, since we got the larger order in squares instead of a roll, the pieces were very easy to work with. The biggest trick is to start the peel back, place the square with just an inch or so of sticky exposed then peel as you smooth. Keeps out air bubbles and allows for a minimum of "straightening" if needed. We have enough squares in the box of 51 to do 3 full layers, 2 below the wood flooring and one on top of it when it goes in. It is squishy enough to make for a really nice padding layer under the final flooring (low pile carpet) that we put down.

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.
