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

Works great and the peal and stick backing makes it super easy to install

The product at least for me worked exactly the way it should have, The adhesion was far better than shown in comments, it was about 45 degrees in my garage it did not budge...I am going to line my subwoofer box next ....

Great for insulating our van

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!

We used it on the inside of a jeep hard top. So far no complaints. The glue sticks. We were worried about the 110° temps and so far so good

Very well made installs very easily and insulates my truck well

We used it insulation to close gaps in foam board insulation in a metal building, it worked well.

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

The 2022 Honda Civic Sport has a noticeably "hollow" and loud cabin at highway speeds. Honda skipped premium sound-deadening in this trim to keep the car lightweight and affordable. So, instead of spending a couple of thousand more on the trim, I decided to give Siless Liner a try and I am stunned by the results. The difference is night and day. I am very impressed by the quality of this sound deadening foam liner. it took me about 2 hours to completely cover my car's boot.

Works well, did both the inside and outside of my F150 front doors, couple of layers on the outside. Super sticky!! Use small sections as if you try a large piece, once you apply it isn’t coming off if you miss align it. Helped my stock speakers sound.

Very good product. Very sticky back

Received this product a day ahead of schedule and started to install it right away. The grid pattern on the paper was very helpful in cutting the correct sizes and shapes. The stickiness or adhesion of the product was incredible! The material formed to odd shapes really well when needed. Overall, the installation was very smooth an quick. I will be testing the effectiveness very soon but so far, I am impressed and this product is much better than what was in place.
