Storystore Foam Insulation Neoprene Sheets with Adhesive,Multi-Function Soundproof Large Marine Closed Cell Neoprene Rubber Roll (W：12 Inch T:1/2 Inch L:59 Inch,Black)

It worked well for sealing the holes and gaps around the window unit. It is thinner than I expected but it does what it claims it does.

I covered up the crawlspace vents with this, and it was easy to cut and put into place to seal them up and keep the cold out

It does NOTHING for sound blocking or sound deadening door panels. Neoprene is a great thermal insulator, it sticks very well. Thermal insulated exposed metal on the firewall .. car stays much cooler in the summer, holds heat in the winter.I glued it over 50mil Butyl mat that actually deadens engine / road noise.

Bought this to cover the outside of an insulated portable air conditioner panel that faded to yellow and was unsightly. Scissor cut and stuck on the cleaned existing mess. It's been install for a month, thru rain, wind, and bright sun. Looks like I just installed it. Very happy with purchase.

I have purchased this before and it is perfect for mounting wired cameras outside. Just cut a circle a little larger than the camera base. Cut a few small slits in the center to allow the cables passage and mount. I did have to trim a channel in the base for the cables but not that big since this stuff is just rubbery enough to seal them together. After a year of exposure the old ones are still white and showing no issues.

The product was very very thin and was hard to make straight cause it comes in a roll so had to lay it down with multiple items on it to flatten it out

Got this to stick to the outside of one of my reptile tanks. It requires less heat output from the heat milk and keeps the ambient temp a little higher even when it’s off. And I don’t have to worry about my gecko’s lil toes being too cold when he climbs on the sides of the tank. :)

The adhesive on the back of the insulation is bonded to tightly the film layer. When trying to remove the film it causes the insulation to be torn off with the adhesive layer.

Buen producto, pero excesivamente caro ...
