DEKIRU Sound Proof Foam Panels Fast Expand, Acoustic Wall Panels 1" X 12" X 12" High Density, Soundproof Wall Panels Self-adhesive Pyramid Design, Acoustic Foam For Wall Door & Ceiling, 12 Pack

I bought this product in order to absorb the sound of my son laughing/yelling/screaming in his room while he is playing video games with his friends late at night.Pros:Self Adhesion - Many of the other products required double stick tape or glue or some other means of getting it to stick to the wall. This product came with an adhesive already on, just peel and stick, no muss no fuss.Sound absorbancy - Like others said, this is not a professional product, and you are not going to get total sound absorbancy with this product. However, I put up several squares on the walls in my sons room and it cut down a lot of the noise that he makes.Meh - As many people had said, several squares did not fully expand when they first pulled them out of the packs. However, I just didn't use those, and noticed several days later they fully expanded.Really no cons to this product. Easy to install and does a good job for the price point. I did not need studio quality sound absorbtion, and this product was perfect for what I needed.

I would like to apologize, previously I had informed that I only received 1 item of the product, but when I opened the box I verified that the four items were present, therefore I apologize a thousand times for having poorly evaluated the receipt of the merchandise, the product is in accordance with the advertised, I confirm that everything is correct.

Im a producer, on Christmas Day I got my very first pair of studio monitors so I knew I just had to get some foam to minimize the sound reflection on the walls. The day I got them I let them air out for 2 days and started to put them up I was very happy with my work but annoyed later when I find them on the floor the next day. I recommend you don't use the included adhesive in the package and use command strips or any double sided tape.

I used them in my laundry "closet" primarily because my neighbor above has a very large noisy washing machine.The tiles expanded in only a few hours (no water needed). They were easy to cut to size where necessary and adhered well. Plus they look cool!

The media could not be loaded. Not sure how these people are getting away with the misleading info not in just words but visual content like photo shop edited pictures. If this is what they consider high density foam and you really want high density foam check and see if they sell concrete pillows bc this is no way even close to high density foam. It’s very light and soft. The shape does bounce back after opening package so I guess they told the truth there but disregard anything else.The adhesive on the back unless they peeled the original 3m cover off and added their own to protect the adhesive and 3m adhesive had just gone downhill recently, IT IS NOT A 3M ADHESIVE and has the tackiness of a cheap electrical tape if you know what I mean.If you decide to buy and then decide to use once you see it’s not what what is described you need to also purchase a can of spray adhesive like the real 3m headliner adhesive from an auto parts store or right here on Amazon m if you want it to last longer than a couple weeks and not fall off what you want them stuck to like I will do.I bought this to stop the echos or hollow sound inside my deer blind and I’m hoping it works bc I have no choice as I don’t have the luxury of time ,season is ending soon so, if you are using for sound proofing it’s not what you want.Look for acoustic panels. Learn from my mistake. I wish I would’ve went with my gut and got the acoustic panels bc these are not, even though it says they are in description.Well I hope this helps someone.

These are not very effective for sound blocking on walls. Also, the adhesive worked about 45 days then they fell off the wall.

I've got to admit-- I was a little hesitant to purchase this product because I saw where some people had given it a bad review because they said that either the tiles were inconsistent in thickness or that the 3M adhesive stickers provided with it were very difficult to separate. I needed a lot of these tiles (enough to cover a 7.5 ft x 14 ft wall), and I needed the quickest shipment and most economical product I could get my hands on. Let me say that IF YOU FOLLOW THE DIRECTIONS, these tiles WILL "fluff up" to the full 1-inch thickness. The directions state that you need to open them and let them air out for a couple of days. We did this and they were perfect. Also, it did take a little while to figure out how to remove the backing from the sticky adhesive tabs, but there's a knack to that, too. All you have to do is place them on the foam as instructed (one in the center and four on each corder), and then you can bend the tile at the edge of a sticky pad, place your thumbnail against the tile firmly IN THE CENTER OF A SIDE OF THE STICKY TAB, and you can peel the backing right off from the center of the sticky tab with your other thumb. It took about 4 hours to do the entire wall, and that included the time to measure and cut the tiles, which cut easily with standard scissors. (I did have a window to work around, and that slowed me down) For about $118 and four hours of our time, we have a very impressive wall that makes our music room look like a cutting edge sound studio. Rock on! :-)

If you order the right one it is two inches. Adhered well without coming loose. Quick install. Bad reviews of this are incorrect that are stating they aren’t 2 inches thick after expansion.

But a lot of them were compressed with the adhesive or something piled up in the corners. They will not expand and are glued stiff.

No es mal material, sin embargo los cortes en las orillas son irregulares, lo que hace que al ponerlos uno tras otro empiecen a verse desalineados.

very thin and the packaging was bad and destroyed the foam frame

El producto se ve bien, pero tiene varios defectos, tarda bastante es tomar su tamaño correcto, dice 3 horas pero le lleva casi un día. El pegamento es de.muy mala calidad le quitas la película y no se nota con mucho agarré, por más que la superficie está libre de polvo y grasa, hay que comprar algún pegamento extra y además es muy frágil, hay muchas esquinas y puntas rotas.. la verdad no lo recomiendo.
