      The description clearly says that these include self adhesive strips on the back of the panels. These DO NOT include any adhesive. I can buy adhesive and do it myself, but I expect some sort of refund to pay for that. Your description is misleading.

      Can these be used in windows for exterior sounds?
      ByAug 20, 2024
      1 Answer | 
      Answer This Question

      These panels are designed for interior use to absorb sound and reduce echoes within a room. They are not designed for exterior use in windows to block exterior sounds. While they may offer some minor sound dampening, they are not the ideal solution for blocking noise from outside.

      Yes, if you want to defeat their purpose. Then they won't work to absorb sound.

          Not as advertised
          The panels did not stick well and half of them did not have the sound absorbing prices. I gave them a week for them to expand and they never did

            No adhesive to stick on wall
            None of them had adhesive to apply them to the wall. In the description is says they do have adhesive. Easy to install: our regular acoustic wall panels install easily using general-purpose spray adhesive and double-sided tape (not included), our adhesive-backed sound-absorbing wall panels come with their own adhesive, you can peel off the adhesive paper and stick it on the wall.

              Sharp Panels
              These panels come shipped in a compressed state. You need to let them expand prior to installing them. The color is very sharp. It really stands out way more than the typical dark gray foam panels. I installed them over a pegboard backing material using foam double siding mounting squares. You can alternatively install them using various adhesives. I chose the foam squares so that I could move them if needed. They are fairly lightweight and do a great job with reducing sounds in the mid and high range. Foam panels like this will not reduce low frequencies well. I am using them in a golf simulator room to reduce the sound from the impact of a golf shot. They are very easy to install and do a great job reducing the sounds. The color is so much better than my other dark gray panels and will most likely intersperse the blue panels with the gray to up the visual look of the installation.

              Great sound absorbing panels, good quality panels.
              There sound absorbing foam panels are great, they are designed for this to absorb the sound in a room, that is why i have installed them in my laundry room around the washing machine. The wall of my laundry room is to a room in which i sleep in and definitely the noise is to a minimum since I have installed things foam canceling panels. I would recommend to anyone who is looking for a easy solution for sound absorption. Really easy to install, I have added double side tape on the back of them that easy. They are great looking and work great.

              they work
              I have wanted these for a while now, these looked good so i ordered them. they arrived well packed and in new condition. there are instructions to get them uncompressed and back to original shape. they have glue applied so the install is just peal and place. the big question, do they work? yes they do muffle the sound and quite the music, i love the.

              Works for me
              I was surprised by the flat envelope that contained these 12 panels! They were vacuum packed and also the panels were interlocked to really compact them. So, I pulled them all apart and let them set for several days, and voila, overnight they had already mostly expanded most of the way. After a couple of weeks, they settled at a depth of 1.75 in., not quite the 2in. claimed, but ok. One of the tiles looked like the end peak was short or cut off after a day, but after the 2 weeks, it finally expanded out to almost perfect. Give them time to fully expand if any look wonky. The adhesive is clear, flexible and gooey like the type used on peel and stick vinyl floor tiles. If you ever try to remove them from finished drywall, they will probably ruin it; so just be aware of that. I’m putting these on my unfinished basement ceiling above the laundry and furnace to dampen the noise that carries upstairs. Its easy to fit them in around pipes etc. and leaves the pipes exposed for continued access. They help.

              Sound absorbing panels
              Wellco High Density Panels come in a bundle of 12. we got them to help with the echo in my husbands recording studio. They arrive in very flat condition and plump up when you take them out of the package and let them set a while. While they are less deep than I expected they do the job just fine. I was very pleasantly surprised to find that the back was fully coated in the material needed to stick them to the wall. Just be sure to clean/dust the wall before installation.

              They do their job - absorb sound waves
              I admit I was skeptical when this relatively thin package arrived at my door - how in the world are there twelve 2-inch foam panels in that? The answer was soon apparent - they are vacuum-packed for shipping. Once open, the 1" or so package expands to usable shape. They are not diamond-shaped like in the picture, more of a triangle (wedge) shape. They come with adhesive already in place for easy attachment to flat surfaces. The $50 question is... do they work? My first very quick test was using one as a 'shield,' about 15 feet away from a 3D printer, to see the impact on direct sound. I measured a reduction of 3dB peak, which was impressive considering that I was simply holding up a 1' square in front of the sound meter from 15' away. I wouldn't call they "high density" foam by any means.... but it strikes me that you don't really want high density for this application.

              It gets the job done. Be aware that the panels do not come with adhesive. You will have to devise a way to attach them to a surface. I'm using velcro.
