Firewall Insulation Looking online, I see a number of insulating and sound barrier materials are available.
Can anyone recommend a product that would work well on the firewall under the gas tank ? Thanks - Jim |
Re: Firewall Insulation My car has the plastic black insulated cover mounted inside by prior owner. It appears to have more temp. insulating qualities than sound. It limits easy access to the indented firewall fuel port and a few other areas screws, etc., and fits and looks OK unpainted.

Re: Firewall Insulation Get the hard molded insulator panel. It looks really good when you are done. There are also "holes" (passages) in the body that let hot air up into the cowl kickpanel areas that you will want to seal. Use a bright light under the hood to find them. And seal around the column and pedals as best you can to keep hot air out.

Re: Firewall Insulation How does the molded panel attach to the firewall ?

It's pretty stiff molded plastic, so it does not take a lot to keep it up there. :cool: |
Re: Firewall Insulation 1 Attachment(s)
I have the Quiet Ride firewall insulator on my Coupe. It is an exact mold of the inside of the firewall. It uses a few screws to attach. It also comes with an adhesive if you want to use it. I did not and the insulator stays in place. It is black in color, however, they also sell a brown paint for the insulator should you want to change the color. It certainly reduces the amount of heat transmitted through the firewall and it also deadens the engine noise. I live in an area where it is commonly 100 degrees in the summer. The insulator really makes driving my A much more enjoyable.

Use a light under the hood, under the car body, in a dark building to look for light leaks inside the car. These are hot air leaks. Then, between the metal body and the inside kick panel, use whatever thermal insulation you like. I put a layer of Dynamat on the metal for a bit of sound deadening, followed by a piece of fiberglass batting cut to fit. :cool: |
Re: Firewall Insulation Jim/GA, Dick M - thanks for the information. I’ve ordered an insulator panel...the SC Lowcountry summer is uncomfortably warm in my Model A.

Re: Firewall Insulation Wow ! I should have installed the firewall insulation panel long ago. What a difference ! I think 75% of the heat is gone, and it’s noticeably quieter inside the car as well. I still have some heat coming from the lower cowl panel area, but have an insulation kit from quietride.com ordered.
Thanks for all the advice ! Jim |
Re: Firewall Insulation Quote:
Any down side to sealing the leaks/holes with judicious (minimal) use of spray foam before adding foam blocks and insulation/sound deadening?? Do rodents like the spray foam, and other reasons? |
Re: Firewall Insulation Quote:
I have had things shipped to me where they sprayed the foam inside a plastic bag pressed in between the item and the box. That contains the foam in the bag, so it does not stick to the item, but provides the desired cushion. Something like that might work. Then the foam would conform to the space but not stick to everything. I have not tried that. :cool: |
