Nope, all 3 have an aluminum backing so they all work well for heat. I like to layer them. Dynamat (50 or 80 mill thick) then the 3/4 inch fat mat on top. That will reduce all of the heat and most of the sound.

FK works well (use two or 3 layers to maximize it) if your on a budget but not as well as the others for sound IMO. I have used all 3 of them for years in different rides.

I like FK inside the vehicle (Under carpet etc) since its not as sticky, and the other two under the hood, firewall or foot wells on underside. They hold up great where the FK and fall down if you dont add tape to it as well.
