Be sure to use their roller to install it, and some HVAC foil tape at the edges and seams.
Also, no matter what the vendors say, these butyl/foil sound deadening products don't do much to keep exhaust pipe heat from coming through the floor. For that you will need true thermal insulation. I like a product made by Bonded Logic called "Ultra Touch". It is recycled denim strands woven together and backed by foil on one or two sides. Inexpensive and works great! Part numbers for a 4x6 roll are:
#11406 -- single side foil
#12406 -- double side foil

I didn't find the double sided version anywhere except at Sachse Rod Shop. Page 102 in their catalog.

You can probably find it if you spend more time searching than I did, possibly in Canada. |
I don't have a heat issue, my A/C works well and it DOES get hot here so I pulled the interior out and put Dynamat everywhere. It was a pain working around the A/C and computer and wiring but it's done. I live in a Northern climate now so I won't be driving it for a couple of months. We'll see. Thanks for the suggestions.

Yeah a 4L60E so about 2100 rpm at 70 mph. Also electric fans but still too noisy.
