I did a bunch of homework on this topic before I took the plunge, and, after all was said and done, chose the Dynamat products. Yeah, I know they cost more, but I also know it has had consistent results, and all that have used it have said it worked as advertised. Do you really want to have to do it again? So, it costs a little more.
There is as all know some R value to Dynamat, but it's an acoustical mat, not a thermal mat. And as stated, there's Dynaliner, the heat barrier product. Why try to use or tout the acoustical product as a thremal barrier? You want a thermal barrier, use the thermal product, no-brainer to me. If you are only concerned with thermal, then use only the Dynaliner. And that's super easy to apply, light, easy to cut, etc.
I did the cutlass project with Dyna products. I didn't line up the labels, I didn't make sure every square inch was covered, and sure it's not as pretty as some other installs. But it works. It doesn't have to be perfect, the impact is so minimal, not even funny trying to compare.
