ATS Acoustics Soft-Touch Sound Absorbing Insulation Recycled Cotton, Denim and Synthetic Textile Batts, 2 Inch Thick, 2.5 PCF, Case of 6

UPDATED Dec 2023: I spoke with a rep by phone at ATS and she stated that the warning notification is required because these cotton batts are stored in the same warehouse with products made of other source materials, like fiberglass. So this product does not have fiberglass in it but the warning is included due to storage. Sounds reasonable. Updating this review. My first acoustic panel has turned out good... now to make 5 more Nov 2023: Just received these and am excited to put them to use in my home studio for better acoustics. I bought these because they are not a fiberglass product, but instead primarily cotton-based according to the Amazon product description which states, "Product Description: Acoustical Cotton Batts are an eco-friendly alternative to fiberglass or mineral wool acoustic insulation. The natural cotton fibers are 100% recyclable and are made from at least 85% post-industrial recycled content, making them ideal for LEED certified projects. ATS Acoustics does not recommend this material for use in applications requiring a fire rating." However, in the package was included a Warning Label stating "Product Safety Information. Fiberglass Wool or Mineral Wool Product. Warning: possible inhalation hazard. Can cause respiratory, skin, and eye irritation." The enclosed packing list states "ATS Acoustical Cotton Batts." So, WHICH is it? Cotton or Fiberglass based?

I had questions about sound panels when I first started looking. I found 95% of the answers on Amazon and ATS Acoustics, the sellers, website. I did have a question about the cotton batts. I called the sellers phone number expecting nothing more than an automated system. I was wrong. Someone answered within the first few rings and was able to answer my question immediately. Lynn and the team were amazing! They made me feel confident and comfortable with my purchase. The shipping was great too. My first order was supposed to take 7 days but only took 4. My second order was supposed to take 7 days but only took 3 days! Packaging was nice and neat with no issues. Everything was as advertised. Customer service is the best I've had. The shipping was fantastic, and quality was great. Thank you ATS Acoustics.

Have you ever wished that you could hear Miley Cyrus in true high definition? Do you think you could contain your excrement whilst listening to Beiber live in a crystal clear sound stage? If you answered yes to both of these questions, you should consider this product. Not only will it prevent you from getting lung cancer from fiberglass particles, but it will also make the worst artist sound like they are singing versus strangling a cat. I pay no attention whatever to anybody's praise or blame. I simply use Applegate Acoustical Cotton Batts to enhance the girth and volume of my tunes. -Wolfgang Amadeus Mozart

I don't have a dedicated theater/music room, so I decided to keep the acoustic panels in a closet until I’m ready to watch a movie or listen to music. These cotton batts are perfect to be used in this way. Since they’re rigid enough on their own to lean against something without collapsing and they don't seem to be friable at all, there’s really no reason to frame and cover them. I’d rather keep them soft and light weight so they’re easier to handle and can’t hurt anything, and even if they do lose some fibers as I move them around it’s only cotton. The sound improvement is huge! I’m almost 60 and have been a low budget audiophile all my life (my current system costs about $7,000 including the TV) and for the first time now I fully understand the term 'audio fatigue'. Reducing the wall sound reflections in my room tightens and crisps up the music or sound track noticeably increasing my easiness and even my eagerness to listen. For the money nothing could have made this big of an improvement. No way! A note for those planning some sort of frame or cover, the batts aren’t 2” thick they’re 1-1/2”.

Very misleading to advertise material is 2 inches . The insulation verifies 1 1/4 to 1 1/2 in thickness That’s 25% less if you do the math. This stuff wasn’t cheap either. Going off of their 2 inch advertising. I bought more than enough for my project. Now I’m a box short. I feel like I’ve been duped Very disappointing!

Wow this works so well at dampening sound. It is so much easier to work with than fiberglass. They are made of cotton so they are nice and soft. No itch. No stink. They smell kind of like chocolate for a while but that smell is not unpleasant and goes away soon. I have treated my voice over studio with by building individual panels and placing them all around the room. When you walk into the studio the world just closes in on you. It's awesome. It is so quiet, with no reverb. I am a professional voice actor. I highly recommend this product and have been using it for over 5 years.

Healthier option than Rockwool or fiberglass insulation. Quick delivery and nice quality

I bought 3 cases to make panels for my home theater and for my HiFi room. After months of research I settled on these. All 18 where close enough to 2” within an 1/8”. Not building a watch am building panels. Overall very happy with the quality of the product. No off gassing or weird smell. Wife much happier then using fiberglass. Shipping is alittle high so buy in bulk and you will save on shipping. Will be buying more for bass traps. Highly recommended
