Sound deadening, Carpet, and floor pan repair questions

Interesting. Comparable insulators to Dynapad seem to be from the HVAC world. I’ll stop by Home Depot or a local store and see what I can find. At something like $80 for 10sq.ft, Dynapad isn’t attractive. If I can find a foil backed product specifically to keep out heat, without being too thick or crushable, that would be ideal. I want it for the firewall and the floorpans so your feet stay nice and cool, and so A/C doesn’t have to work as hard.

I’ll get some Kilmat ordered pretty soon probably and start shopping around at hardware stores for an insulator. Thanks for everyone’s input. I’ll update this thread.

PS. It might take me a bit to get around to any install. My estranged mother passed away from covid yesterday and it hit me pretty hard. Have lots of arrangements to make for her.
