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.

A bit expensive for what it is. It's on the thin side, which is good if you're packing this into an enclosed space, but the heavy rubberized back side does a decent job reducing low frequency sounds, much more than just the lightweight foam does. Quality is middling, and the layers are prone to separating but it's fine if you install it once then don't touch it. Size was as advertised but again a bit small for the price of over 20 bucks. I didn't try to cut it but it should be easy to cut with a box cutter. I mounted the whole thing to the side of a noisy furnace to cut down on sound bleed into the next room. It's not really meant for hanging on walls as there is no included adhesive, but I guess you could staple or nail it to the wall.

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.

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.

Works great and is easy to mount.
