Sound Dampener/ Insulation Suggestions Wanted

[VillaTA]

I am looking to add firewall insulation and sound dampener to the interior of my TA this fall. Looking for suggestions. I have used Second Skin Damplifier Pro in the past. It is a great product for sound Deadening but I’m not sure about how well it reduces heat. Plus it was not asphalt based so no off gassing of VOCs.
Any success stories out there that can reduce or prevent the firewall heat transfer?

What's wrong with factory style pre-cut firewall insulation?

I used Dynamat for it's sound deadening and heat barrier qualities. I know the off-gassing can be an issue, but I'll drive with the windows down for the first couple months if necessary. I used this in conjunction with the factory fiberglass insulation at the kick panels and firewall wanting to get the most bang.

It isn’t working well. After about 20 minutes of driving, the heat transfer becomes bothersome.

Let me guess, you're running headers?

I have FatMat and double sided aluminum jute heat barrier in my Coronet. I'll post the link from Summit.

Summit doesn't stock it anymore. Bonded Logic Tru-Max Super Insulator. Amazon doesn't stock it either. They do have a single sided product that would work.

Speedway Motors has the double sided heat barrier.

No headers.

No headers.

I'd recommend using a header wrap product on the exhaust pipes from where they exit the exhaust manifold back to the seat area. Stop the heat before it gets to the fireawall.

I haven’t heard this complaint without headers in the past. Before my restoration, heat from the floor seemed to be an issue for me in the summer. I just used the dynomat and sound and heat almost gone. Make sure you don’t have any open holes in the firewall….
Lizard skin makes a good product as well.
Good luck to you.

Def no holes in firewall. Only happens after about 20-30mins of driving
