Dash insulation for non oem builds

It's funny, it's been so long since I've pulled my original deteriorated/rotted dash insulation out, I've forgotten what actually held it in place.

Nothing is original anyway... I have a semi-smooth firewall, vintage air exiting out in the fender, drive by wire pedal, etc ...
I've also sprayed the bulk of the panels with thermal and sound deadening spray(Lizard Skin). I've since modified the firewall and wanted use some extra insulation and sound deadening on the firewall.

What's the preferred for non original builds? I see multiple foil stick on types and hear people going to Homedepot, etc, etc. Is a stick on foil based insulation good enough for the firewall or do I need to use some kind of thick padding?

Everything is just sitting in place, I'm about to pull the electrical, steering column, and evaporator to paint the dash anyway...

Re: Dash insulation for non oem builds

There is a firewall insulation pad that covers the wall. It is made of jute material. I don't know how it is fastened. Below is a link the reproduction part:

Sorry about the Firebird website. I am sure there are Camaro websites with the same part.

The photo below shows part of the insulation behind the glove compartment. My jute material was eaten by a rodent.

The next photo shows what was under the steering wheel part of the dash. Not much in the way of sound deadening.

I applied Lizard Skin to the outer cowl area where the windshield wiper transmission goes. As you know, this area is prone to rust. I seam sealed the area first, then I applied Lizard Skin. The Lizard skin helps seal the area and provides some sound deadening to the upper part of the firewall. It might be too late for you to do this.

Re: Dash insulation for non oem builds

Yeah, you and I did the same with the Lizard skin. I was about to order the Jute mat and didn't see anywhere in my new firewall to mount it to. I'm thinking the mounts go through the firewall and I didn't want to do that on a smoothed firewall. So I thought about just adding some of that foil based insulation to the firewall.

I maybe over killing it with the lizard skin and foil or jute, but I've always felt heat coming from the headers around the firewall and floor in my past cars. Just trying to do it right so I don't have to go back in later... Once I'm done with under dash area, I don't plan on revisiting it more than I have to.

Re: Dash insulation for non oem builds

I'm installing this adhesive-backed sound dampener :

I just got the evaporator installed for my vintage air 68 non-air convertible.

Re: Dash insulation for non oem builds

I ended up using the adhesive heat/ sound barrier stuff first then the single sided foil backed material following the header, exhaust & muffler routing for extra insulation.
