Nuogo200 mils 50 sqft Car Heat Sound Insulation Mat Automotive Noise Deadening Mat Heat Insulation Pad Automotive Sound Deadener Self Adhesive with 2 Rollers for Hood Engine Roof Trunk 18 x 394 Inch

I used this on the interior bedroom walls of my motorhome to reduce noise while sleeping. Because the top layer is foil-like it was easy to rubbed fingers around window trim and then make the cuts to fit snug. A few times (doing this solo) it did stick to itself in the beginning until I got the hang of it. I went horizontal...so kind of a pain. The sticky backing is very strong and the included rollers made a quick job done flawlessly. It did hang on the wall several days before I put paneling over it and in that time a couple holes where I wasn't careful about it. I don't think that is going to make any difference though. As for heat barrier I cannot express the cooler bedroom I now have. The day after I finished it was 102° and it wasn't hot inside. I plan to do the rest of walls this way in the future as warm weather rvs heat up quickly. I'm curious to find out if winter will keep the heat in and cold out. Already ordered another roll. The thickness and length you get cannot be beat.

Overall the product was easy to work with and made a great difference for insulation. It also worked for the head liner replacement insulation.Was very pleased with your product.

Great item for the price, worked as intended. Sticky side not super sticky, added spray glue to help. Product was used to add sound damping to a Toyota Corolla. Would definitely recommend and will use again.

Great product for what I paid. Cheap and works the same or better than the original sound deadener.

It was easy to install also it really made a difference, because i had a loud wind noise but its almost gone. I used it for 4 doors only and there is too much left of it.
