BXI Double Noise Blocker Sound Proof Foam, 39.4 X 13.4 X 1 inch Egg Crate Foam Rubber Sound Deadening Material, Sound Dampening Acoustic Panels for HVAC, Pipe, Machine, Window, Wall, Door

Works well! I've had mine for a while, and while its not magic, it definietly helps muffle any annoying sounds laying around. The price for the size is great, and its extremely high quality, and the adhesive on the back is almost too well built, it is ment to stick and stay stuck. Overall recommend.

Small piece, hard rubber on the back, difficult to cut/fold/align. For the price they charge for such small piece. Weird combination of material, very limited purpose/use. I purchased to fill in some space for sound block and regret buy it, it does not bend and doesn’t eliminate sound. Waste of money.

Part 2 of "i needed to treat my walk-in closet for VO work". This thing truly works great, I just hated how long I had to leave it out and have stuff on it to get it flat enough to paste it to the wall. Otherwise, great, quick and easy install, light so it's not gonna fall all the time, I punched it a couple times so it's definitely durable... like yeah, get this thing if ya wanna get some good treatment.

I bought this to make a window plug for my bedroom window. My neighbor has been terrorizing the neighborhood for months with his HEMI engine at all hours, and this is my last ditch effort to try and get a full night's sleep. I had tried butyl on posterboard first, but it was a major failure. The butyl was way too heavy and didn't provide the sound dampening I needed or expected. Ended up being a complete waste of money. Not something I would recommend for anyone trying to build a window plug, unless you're using wood (not cardboard) and are prepared for a heavy lifting session every time you put the plug in the window. This acoustic foam ended up doing the job way better and makes a much lighter weight plug. I took the extra step of sealing off the edges of the window with gaffer tape, and between that and the foam plug I haven't been awakened by street noise. I used the recommended 3M mounting tape to install the foam vertically onto posterboard the height of the window (36"). I positioned the product as such that foam protrudes from either edge, to make up for the fact that the window is 51" wide but the posterboard is only 48" wide. I had to trim the foam a little bit, and use the scraps to fill up any gaps or cracks when I lift the plug into the window each night. My bedroom is almost completely light tight and so far I haven't been awakened by the demon car since using this setup.🤞🏻 I'm giving 4 stars because it isn't perfect, but it's close. I'll update if anything changes. UPDATE: It's been a few weeks and this stuff has completely changed my sleep. I am no longer awakened at all by street noise or the demon car! Increasing to 5 stars because it did what I bought it to do.

The stickers provided on this product are very weak. The foam itself might help reduce noise, but it constantly falls off any surface because the adhesive doesn’t hold. I had to look for an alternative way to mount it. The sound insulation may work, but the installation method is very poor.

Not only is the foam a good density but the rubber back really helps kill noise.

Too expensive

Arrived very clearly used, with dirt, black stains and chunks of foam missing.

Esperaba mayor capacidad de reducir el nivel sonoro, buen acabado y materiales de calidad

very effective sound absorbing material..In removing our dishwasher to repair a defective part, the upper or top insulating material that came with the unit was damaged and ended up being jammed and we were unable to properly return this material to its original state.. So i ordered this foam material,...It cut easily to the correct size and was very close to the original thickness.Secured to the top and reinstalled the dishwasher and it is as quiet as its original state

The material is awesome. Holds in heat also. I use it as a sou d box and I gotta say it's good with holding sound also.

Apenas me llego y no lo he puesto a prueba pero se ve de buena calidad y es idéntico al de la foto

Nice but i believe quite expensive for the size that i received
