Siless Liner 157 mil (4 mm) 36 sqft Aluminum Foil Finish Car Sound Deadening & Heat Insulation Closed Cell Foam - PE Foam Sound Deadener

Sticks really well. Thicker foam than I anticipated. Also reflects heat which is nice. Great product.

Very good and easy to work with

When it arrived I thought it felt a little less dense than some other products I’ve seen. It works great though! Noticeable sound dampening. I also used it to line the inside of my aftermarket air box on my duramax truck and actually lowered my intake temps a couple degrees. Also used it to insulate my A/C accumulator on the same truck and noticed my A/C got a little cooler. The adhesive works great just make sure you wipe clean with alcohol/acetone/etc. the area where it will be installed

Very good stuff really really helped 2001 f250 7.3 made it much much quieter then before! Very impressive! Ac works great now ice cold

Easy to use.. super sticky.. easy to cut to shape where you need it.

I've only placed a few pieces so far. However this stuff is super sticky. You will not have to worry about it falling off, just clean surfaces prior to placing.

Great product! I doubled this up with Siless Sound Dampening material as well. I did a double layer of this insulation on the ceiling (same as in your home, more insulation up top) and single throughout the rest of the car, in my effort to turn my CUV into an interior camper for winter snow storm chasing! Looks great, easy to install, and I got to support the Ukraine! (I was leaning towards Kilmat products but they are made in the Russian Federation... with everything going on right now, it was a no brainer)Only downsides is (1) that you need to be really careful while handling it, because the stickiness WILL stick, (to your fingers) and if you handle it too much, you will pull some of that off. As long as you are careful there, you will be ok. (I personally cut the pieces to size/ smaller the better for tight spaces/ putting up behind other lines/hoses in the car... and then for the 2nd layer, I made sure I overlapped the seams so that there was no gap where the heat would escape through).Second Downside (2) is that I need a little bit more, but not a whole roll more worth... 50 sq ft would be better for what I needed it for, but whatever - I am being nitpicky at this point.Overall, Great Product/Looks Great/ I HIGHLY Recommend!

Used in my truck and reduced the noise of my big tires!
