Really made a difference. I added it to the doors and back of the trunk as well as putting it between the speakers and frame. Really helped with outside sound. Make: Honda Model: Accord Year: 2023 Warning: super sticky once it's on its on!

Nice product. With adhesive applied, this an all in one product. Easily cut to random shapes and dimensions and the adhesive seems to hold well. Removing the paper that protects the adhesive to apply in tight areas, presents a new set of problems. Having applied the product inside the panels of an old Trooper, it is yet to be determine if sound and temperature transfer are reduced.

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!
