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

Good quality material, very good adhesion for my aluminum fuel tank. Will definitely recommend this for insulation from heat.

This product worked great and can tell the difference with and without it. Just needed to buy more to finish.

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!

This product does not perform. It shrunk by around 25pct after exposure to heat and sunlight covering the cars Panoramic Roof.

Very sticky so be sure to dry fit the panels before to take the vinyl strip off , because as soon as you touch it to the metal there is no adjusting it, however it really does what I wanted it to , to reduce sound , vibration and heat inside the truck cab

Justice to shape, peel and stick. Adhesive is strong so be sure you get it on the right spot the first time.

I'm not sure what the foil adds except a layer on top to rip. These used to be simple closed-cell foam but I have no idea why they are including a micron-thick layer of foil to the top - for what reason???These are not forgiving to work with. Once you lay it down, it sticks, and will rip if you try to reposition. This makes them very hard to work with in tight spaces or when trying to slide under something.

My husband absolutely raves about this insulation. Super easy to work with, install & cut to shape. He did an entire floor & inside wheel wells of a jeep wrangler before new flooring was installed. Highly recommend
