Acoustic Panels 12 pack Self-Adhesive 2"X12"X12" Quickly-Expand Foam

I looked at a lot of these products and chose this brand with their no headaches pitch expanding and applying these. Full body adhesive was a critical reason as well. I bought a 36 pack and only 2 had any type of issue expanding to a perfect from, and honestly, the only way to be absolutely sure they come in perfect form is to never compress them, and that just raises cost of packaging and shipping. The 2 that didn't snap to perfect form, we're just talking one edge being about 1/4" lower than perfect, so it is all perfect for my needs. They expanded fast, however, I let them sit out with only 3 high in each pile for 2 hours before I came back to look at them, so excellent score at easy expansion description. Adhesion is also a great score due to full body adhesive, however I am using them on a resin walled shed cleaned with 95% isopropyl alcohol, so the adhesive does not touch 100% of a surface to fully adhere. They are up and good so far, but I do not expect them to stay that way as the temperatures change. If they don't, I'll know exactly where they go and reapply using some car headliner spray glue, that will most assuredly keep them in place. For now, I'll hope to keep it mess free and see if they hold their place. I am using them to keep my CNC machine noise down a little for my neighbors since I don't have the room for an enclosure. These panels along with a different sound insulation product designed for cars, mostly applied to the doors of shed, they actually works well. I don't have any sound measurements, but my own hearing tells me it was all worth the $80 in materials as I like my neighbors, most of them anyway. I barely hear it 12ft away from shed and that's with the 16,000 rpm Dewalt router. With the 4 extra I had, I placed next to the 60db air compressor, if the adhesion works out, I'll buy some more and fill out that wall and those 2 sides of shed being covered will do a good job as there isn't anyone on the side of the other 2 walls. Turns out my work enabled me to seal up all the cracks that allowed air to come in (besides designed vents that I cover with removable material), so in winter, I'm already ahead of the game keeping the shed warm when heater is on. Best $80 and 2 hours work done to this shed yet.

I used these panels in my closet, and once out of the packaging, they didn't take long to air out. They were way easier to stick on than other brands because of the adhesive backs, so hours worth of work was cut down to 30 minutes. After a couple months, none of them have unstuck. They mold easily around two planks I have on my wall, around corners, and it dampens reverb well when recording. I'd definitely buy again

Got them today, did my measuring and placement testing. Opened them up and let them sit about 30min and they formed nicely. Super easy to place on the wall, and they stayed nicely. Noticed a difference right away, not so tinny and echo-ey sounding now, more full sound from my Towers and Center. I'm running Klipsch speakers in a 7.2.2 configuration. Have about 15 sheets left so I have some more to use. Biggest difference was setting them up behind the center channel and TV area wall.

It did the job pretty well. I would buy again, loved how easy it was to place and the hold is awesome so far.

After tiles are installed, the acoustic padding often separates from the adheasive backing, and the padding falls to the floor, leaving the adheasive stuck on the wall. It usually takes a day or two for this to happen. I have installed this product in the past snd had no peoblems. With my latest purchase, t's a crap shoot whether it will stay where it is installed. Not recommended.

I have a small theater room and in the rear I have my racing sim setup. So I added these all over the rear of the room to cut down on sound bouncing around. Worked like a charm. These are super easy to install and they really do work on cutting out echos and sound that you don't want. Would recommend to anyone looking to control acoustics in their room. Update: I've purchased these a few times. The most recent order seems to have dropped in quality significantly. The adhesive on the back is very weak and doesn't cover the back of the panel. Causing them to fall off my wall. The panels are also cut improperly. So they don't line up properly. I'd be very cautious purchasing these with high expectations.

These are great for that pro studio look and feel! These really do fully expand within a few mins like it says. Yes the adhesive backing does work beautifully with one catch, you have to read the one key instruction that says “clean the surface you’re sticking them on first.” I used Lysol Disinfectant Spray, let it dry for a few mins and I haven’t had any problems after a couple weeks of them being stuck to the wall. Before sticking them though, I used thumb tacks to place them on the wall in the design I wanted to make sure they would work in the area I wanted. The only con that you personally may have and it is not a con for me is: These do not do much in terms of sound dampening. They do a little and I can hear a mild difference but nothing that’s going to be useable for a live band or loud environment. For me, I knew these weren’t going to be that and I was okay with it for that’s not what I bought these for. I needed these for video content and over all atmosphere feel and these are excellent for that!

When h place this make sure they are snug they shrink and will have spots between if you don’t but all in all good buy
