GUERRI 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.

I’m extremely impressed with these 12” x 12” x 2” soundproof foam panels! The 36-pack was perfect for covering my recording area, and installation was simple—I used a mix of adhesive spray and double-sided tape, and they’ve stayed firmly in place. The wedge design not only looks professional but really makes a difference in sound clarity and echo reduction. My room now feels like a proper studio, and the overall audio quality has improved dramatically. The foam expanded nicely after opening, and the consistency across panels was great. Fantastic value for the price—highly recommend for anyone doing voiceovers, podcasts, or home recording! Unfortunately, the last order had a price increase which I'm not happy about because I plan on buying more.

Worked great nice product

These are vacuum sealed, so you do have to pull them out and let them inflate for a day or so, and some of them you do still have to pull apart from themselves, as they come stuck together. They are thick, but some of the foam was damaged - thankfully that didn't matter for me - and they have an odd scent. Somewhat of a chemical smell. These do NOT have adhesive on the back, and you do have to purchase some form of adhesive spray as needed. I initially tried to attach them with glue dots (to not damage the wall) but realized that wouldn't hold well enough.

Great product.

Looks and works great but do let it sit out and fully expand, can soak in hot water to help expand and let it dry but do let it sit before hanging. Place tightly close to each other they do shrink a touch after time.

Exactly what you should expect

They don't work and sticking them up is a nightmare. They cancel no noise and are not thick what so ever, any glue you try to put on them gets absorbed and you're left with the glue on your hand as you try to stick it to the wall. Save your money and get better ones. I don't know if they changed quality from everyone that gave them a 5 star, but they are not dense, they're squishy, they cancel no noise, and they are such bad quality that you could easily tear them if you're not paying attention like the good ones you can find elsewhere.

الفوم خفيف جدا أقرب للإسفنج وبيوبر لو مررت إيدك عليه ينفع منظر فقط ولكن لا أنصح بالشراء مطلقا.

في منهم متقطع و مترب و متداس عليهم و اثار كوتشي عليه و الوانهم مش زي بعض في البيلمع و المطفي و الغامق و الفاتح واضح اوي اختلاف الالوان و هما متعلقين على الحيطة غير ان ملهمش اي فايدة ولا عازلين صوت ولا حاجة للاسف كان نفسي ارجع البروداكت بس فتحت الكرتونة بعد شهر من الشراء
