What insulation to use on firewall

[Max440]

I have a 1967 /satellite that everything is out of thus a very bare body at the moment. What insulation should on the firewall. Also what should I use above the headliner. I want to deaden the sound as well. I was thinking Dynomat on the floor. Any suggestions would be welcomed.

Thanks

On this website seen bubble duct wrap aluminum backed applied with spray glue to firewall. Can buy at Home Depot. I used boom mat on floor of my Dodge. Didn't cover area on tunnel, want to cover flat surfaces first. Car's kind of noise, it helped well for dollars spent. There are similar products cheaper bt can't say I've used them.

Go to the "Foam Factory", and buy "Gym Mat". Comes in different thicknesses, and 3M spray-glue it to your surfaces. It's black, closed-cell foam. I use 1/8" in my cars. It's cheap.

The Boom Mat I bought on Ebay vendor uspartsoutlet in June 16. There vendor rating wasn't perfect but I had no problem. I searched a lot to find it at that price. B/M part 50210, 10 pieces 12x23 inches $89 bought 2 of them. There are foil with what I would say is sticky tar. They have plastic sheet you peel off and apply. Cut to shape first then peel. They say you don't need 100% coverage. Read up on it think they 50/60% coverage is good.

Use what is recommended here or what you can afford. I used generic hardware store stuff. Yuge difference. Good job doing the ceiling if headliner is out. Will make a great improvement.

I hate dyno mat you ever try to remove it, terrible stuff... I don't mind the factory stuff, get all the pieces, firewall, headliner, juke, and I put a layer of double wrap insulation under the carpet no glue.

I restored a 68 charger and the guy who did the car before me put dyno mat everywhere inside the doors, quarters, trunk, firewall, stuck it to the inside of the console, in the dash board, even behind the back seat, it was a mess, it had to cost him $1000, lol...
Worse part was I couldn't remove it and he painted an original red car a try coat pearl white, lol.. I tried blasting it, freezing it, solvents, ended up heating it and scraping, and some of it got masked and painted around lol..

in my experience, if you do all the factory stuff- firewall insulation, kick panels, carpet, juke, headliner, trunk divider, door plastic sheets, and then add a bit of double wrap (I use 3m double sided tape to hold it in place) inside the doors, quarters, trunk, dash, where ever you can fit it, it works as good as dyno mat...
