For floor and roof installation, we always recommend Siless 80 mil first and then Siless Liner 157 mil on the top of it. **Q: Will this work on the underside of the car as a heat barrier/shield from the exhaust** A: I think the foam would melt or burn and get too hot if it was real close to the exhaust pipe underneath the car. probably wouldnt stick well to the dirty underside anyway. However, if you apply it on the inside of car body above the exhaust area you will lessen the flow of heat (and noise) into the interior. You can also apply several layers to increase the R value. **Q: Would this work goodon my van walls** A: Thank you for your question. Yes, it will be good for your van walls. **Q: What is the thickness of the foam? Could it be cut into a one or two inch strip and wrapped around a 3" tube? Does it scratch easily?** A: It is 157 Mil 37.5 Sqft. Yes, you could cut it into one or two inch strips. It has self adhesive side, and you can install it around a 3" tube. It is not easy to scratch it, but everything depends on the environment where you install it. ## Customer Reviews ### ⭐⭐⭐⭐⭐ GOOD PRODUCT // ARRIVED IN ONE DAY//WORKED AS ADVERTISED *by 2***T on February 6, 2026* 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 .... ### ⭐⭐⭐⭐⭐ Easy to use *by O***L on December 19, 2025* Very sticky it worked well for me to insulate truck roof. ### ⭐⭐⭐⭐⭐ Great product. *by E***R on August 13, 2025* Really made a difference.
