SmartSHIELD Plus - Aluminum + XPE Foam + Glue - Thickness: 3mm

Used this for padding my interior to reduce vibration… works great..

I am in the process to convert my Nissan NV200 into a micro camper, and the first step is sound proofing. I started with three different rolls of different sound deadening material and this one came out in second place.Why?- it is quite lightweight (like my others were)... if you want weighted soundproofing material, it will cost you much more. This is an economical solution....- it does have paper as backing material, which I was supposed to pull off to expose the adhesive side. Paper is good, as it doesn't easily break during it being pulled off. I had other soundproofing material with thin see-through plastic that drove me crazy during me trying to peel it off.... took way too much time. So this is the reason this material comes in second.- and as far as ADHESION goes: not very happy with it! As you can see in my photos, as long as the material was laid out flat and straight, the adhesion was no problem. When I came the next day to my car, the pieces that were on a curved spot came un-done! Since I continued on my project, I pressed those pieces back into place and then applied my insulation, and then my walls, so this adhesion issue wasn't a biggie.... but just goes to prove, adhesion isn't 100% great!Since doing this soundproofing work, I was able to drive around with my micro camper some, and it IS quieter in back, but it is hard to tell what helped to keep the sound down because the soundproofing was just part of thickening my walls..... however, if you look at van builds, everyone does soundproofing, and so did I.I wish there were a line guide printed on the paper backing so I could have cut my pieces in straight lines.Overall, I give this 4 stars for good padding, an easy peel-off solution (brown paper) but marginal adhesion.
