Siless Liner 157 mil (4 mm) 9 sqft Aluminum Foil Finish Car Sound Deadening & Heat Insulation Closed Cell Foam - PE Foam Sound Deadener

used on the roof of my 23 forte. has helped with the Texas sun on blocking out heat along with heeping my ac cool.verry stick no smell. help with redusing vibrations from my subs. light weight and easy to apply. it will stick to what ever you put it on so dnt drop it lol

Extremely sticky and good heft. Once they go on they’re not coming off. 4 mil is accurate. Highway noise is much reduced in a tall Sprinter van. I still have a lot left over so I’d say it’s a good value and size.

Very difficult to use. I tried to use this on the inside roof of a 71 Plymouth which has a lot of stiffeners and recessed supports. I've used a lot of the three in one Silas sells, and it is a little forgiving if you need to adjust the placement and haven't pressed it in place yet. This stuff does not!Once you lightly place it, it's stuck. When you pull it off, the foam layer stays behind and must be scraped off.Works great for simple surfaces. If you need to slide it under other structures like stiffeners, find something else.

Seems to be a quality product. I have not put it to use yet. Comes in a nice box too

Quieter

Very Impressed! This is nice stuff!

I've only placed a few pieces so far. However this stuff is super sticky. You will not have to worry about it falling off, just clean surfaces prior to placing.

Very good stuff really really helped 2001 f250 7.3 made it much much quieter then before! Very impressive! Ac works great now ice cold
