BXI High Density Rubber Backed Sound Proof Foam, 39.4 X 13.4 X 1 inch Dual-layer Noise Reduction Foam Roll Sound Deadening Material, Sound Dampening Acoustic Wrap for HVAC, Pipe, Machine, Window, Door

This stuff is high quality and worked way better than I thought it would. I split it down the middle and used a piece for each rear strut tower and wheel well. I did not glue it to the car I glued quality magnets to the rubber side. It's plenty flexible and this keeps moisture from damaging the car and of course can be pulled right off for inspection. The rear seat holds the rest in place. Amazing how quiet it is to have a conversation with someone in the back seat doing 70 down the highway. Yikes.... if more people understood this it would put the luxury car market in serious jeopardy. Anyway, this was my particular use for it and I am impressed. Also thanks for not shorting the length. I think it was even over by half an inch. Rare these days to get anything that is honest.

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.

Expensive for what it is. I put me cellphone in a box with music playing and wrapped it in this foam. Barely made any difference. The foam is just thin egg carton foam used for mattress covers. Not dense enough to do anything. Rubber backing is good quality but overall, not fit for purpose.

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 true to color, it’s more of a swimming pool blue than the aqua/ teal pictured. With that said, it’s a really nice rubber backed foam, high quality. Good price.

I couldn't be more pleased with this product, it lets me sleep well at night. Here is the thing, I have my kids bathroom adjoining our master bedroom, with their faucets in the wall between. Despite telling them to shower early, they would invariably get into the shower late in the night (yea, teenagers, right??), and the loud noise from the faucet would really disturb my sleep. Very annoying. Well, recently we had to open the wall to detect a leak (story for another day), that's when I saw the opportunity to insert sound proofing around the faucet and found this product on Amazon. Frankly, I wasn't expecting it to make a big difference, but lo and behold, after the installation and sealing the wall, the loud rumble of the faucets is reduced to a faint muffle that is hardly noticeable. Wow! I can sleep again at night, and best of all, don't have to get into a fight with my kids about when they should use the shower :)))).

Too expensive

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.

I was impressed at how good the quality was and how well it worked. My only wish is that I could get larger pieces of it to do my entire firewall of my truck.

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

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

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

Correct, mais pas aussi efficace
