Sound Proof Foam Panels - 12 x 12 x 2 Inches 36 Pack Wedges Acoustic Foam Panels Sound Proofing Padding for Walls and Ceiling High Density Foam Studio Foam (Black)

These are really dense foam. If you've tried to use 1" these are another level of hush. No need to do water on these. just fuss with the mashed edge, working down, pull little bits apart and rub your thumbs trying to spread it open, but do it light enough you don't tear the edge. Just a light pass, most of it will fluff out, go back and rub, stretch the edge and it's easy to get the hang of dealing with smooshed ones. Alternate the panels as you build your enclosure or wall. I put 48 of these in 6's and 4's in a 10x14 room and it is so quiet in there now! If the house is all quiet, then the silence in this room is deafening haha. These will block a lot of mid to high sounds. Pyramid will block high end, for mid-range to lows you need thicker than 2" or layer with another material like felt or wool.I did make gains in deadening workshop sounds, but I learned I'll have to do corner pieces, and more than just hang foam on walls for better soundproofing.I used a gummy spray adhesive, just a line around the edges and a fat dot in the middle and none have come down in a few weeks now.Overall, I love these and probably buy this particular brand/vendor again. They are either cut with a dull blade it looks like or it's just mashed and cut, but they never fluff it out before sealing it up with vacuum. I think it took me about 35 minutes to fluff out 48 panels. I still have a couple packs of them, but once the outer plastic is open, the unopened ones expanded in a day inside their pack.

They dont stick. I bought small circles that were recommended. They didn’t work. I bought double sided tape. It didn’t work. I tried gluing it on. It didn’t work. Use the troubleshooting and it tells me to quote. Remove the adhesive backing from the panels“ but these have no adhesive backing. I would like to return them, but in order to put them up there, I had to cut several of them

This foam expanded right away, looks and feels high quality, and the smell was gone in just a few days. High quality. This is BY FAR the best value for quality, thickness, price compared to a few others I’ve tried. Absolutely would buy again.

I like these for insulation a storm shelter from the echo of the concrete walls. These also help with keeping the heat in the shelter if the weather is cold during the storm. These work well FocusSo9und "Yellowpoint" round double sidedd adhesive stickers.

Great products super hard to stick and line up with the grooves and try to switch directions with it didn't look very good as far as sound damning not 100% sure I got the two inch it was okay well I don't think it dampen the sound is much as I was looking for

Read a lot of reviews on numerous/similar products. This one mentioned a horrible smell that lasted days after opening the package. Mine did smell a bit when I took them out, but it went away after about 10-15m.The sound absorption for what it is and the price is pretty decent. Had a very echoey room. After putting up all 36, there is virtually no echo to be had.Most fluffed up to 2" thickness right away, but some did not. I put all of the panels in the dryer on low for about five minutes and they all puffed up to the expected thickness. Definitely recommend for someone trying to lower echo/etc by way of small panels.

Helped with sound some.

Look good
