Storystore Foam Insulation Neoprene Sheets with Adhesive,Multi-Function Soundproof Large Marine Closed Cell Neoprene Rubber Roll (W：12 Inch T:1/16 Inch L:59 Inch,White)

Worked great to insulate part of my reptile tank

I use this on either side of my window AC and it insulates really well.The only thing is the residue is hard to clean off the window

It is pretty sticky.you need to really line up we’re your going to stick it or it’s going to be a bit of a problem.We will see if it remains All in All seems to be a pretty good product.

I bought this to see if it would be a cheap alternative sound insulator for my desktop PC that I keep in a cabinet by my desk. The pc would reverberate at just the right frequency to essentially turn it into a subwoofer. I bought the 1/4" roll and lined the inside of it, and along with some padded feet, reduced the noise by over 50%! I don't even notice it anymore, and it probably saved me hundreds trying to over-engineer a quieter rig. Thanks!

Extremely sticky backing

This says neoprene, which it might be, but its so thin it just tears.The sticky back is convenient, but that's about it.

After reviewing numerous types of replacement insulation for the inside of my air handler I chose this neoprene insulation. This neoprene insulation rolls out nicely, is easily cut to length or shape and it provides an excellent insulation barrier. I have had it installed for more than 6 weeks and no more air handler “sweating” (condensation dripping). In addition, this insulation does not deteriorate in water. Great product.

Useless and very expensivemust be made in China
