thermal protection
I have stripped the interior of my car and started to install a purchased pre-cut heat insulation kit. Not at all satisfied with the kit. Now will start from scratch. Convertible, so not concerned about sound. Only care about HEAT. In your opinion what is the best product to "abate" HEAT and where to order. Osh sells something with foil on both sides and plastic bubbles in between. Wondering how that stacks up against mail-order products and if anyone has used it. Curious if bubbles will pop if used on the floor. Thanks.......

First if you have under car exhaust and headers, I'd highly recommend a ceramic coatinig on the headers. Before coating my headers, I couldn't drive my car with bare feet, (insert redneck joke here), I wear flip flops in the summer, so the first thing I do is kick them off in the car. With a coating, now I can. Sorry, I don't have any experience with insulation to add any useful comments.

I just redid the insulation in my 79. I used ducting insulation from Home Depot. It is the same as hushmat. Cost 16 dollars a roll and I used 4 rolls to do the whole interior (front and back), under the seats, up under the dash as far as I could reach and both doors. Used the silver ducting tape to seal everything up (2 rolls). Go to home depot and you will see it by the thermostats. 1/8 inch think, about 18 inches wide and silver. it is sticky on one side so it help in the molding it to the floor.
I also used a high temp primer and ceramic spray paint on my headers and my car is very enjoyable to drive now. Before, my feet would burn up like C3 said.

Still interested in others opinions because I really only want to do this once.

The jute backing is not much protection at all. The stuff I put in reduced the noise and heat. I could not drive it for very long because my feet would burn up and it just got too hot in there. This stuff really reduced the heat alot, I enjoy my car now. I just pulled the old carpet, spent about 2 days putting this stuff in and put the carpet back in. You can cut it with scissors and I tapped every single seam with the tape.
I left the jute backing on just beacuse the carpet was only about 10 years old. Some of it came off. I even put it under two of the storage areas. Not under the battery though. I ran it all the way up to the window in the back.
Night and day difference.

Be careful with some of the Bubba/Home Depot stuff. Some of it is actually flamable. Some of it stinks really bad when it heats up. I am all about saving a couple bucks here and there, but having to redo things sucks and doesn't save anything in the long run.
Buy the products designed for this application and be assured that they work as advertised. I just ordered a kit from Rick @ Raammat to help with noise and heat on my '78. Not going to try the Bubba method just to redo it again in a year or so when it falls apart.JMO

Your aftermarket kit should work, but probably needs fitting and tweaking. Lots of folks use Reflectix - Lowe's or Home Depot.
Almost all C3s had some sort of factory installed sound/heat barrier under the front carpets and around the tranny hump.

The best thing ever to stop heating from getting into the cabin is to put some heat insulation sheets from outside, I did that to my car and I'm very happy, its a big block with long tube headers going under the car and even when temps over 100* and A/C on I couldn't feel any heat coming from the engine or trans. tunnel. I also use Reflectix sheets under the carpet, but I feel that the Zero-clearance sheets are doing the greater job.

When I was doing the interior of my 69 I used some ceramic heat barrier, it was a brushable stuff and I used it on the underside of the car, then the reflectix under the carpet, it still got hot!
When I swapped headers I wrapped them with that DEI stuff, that is what made a world of difference, by eliminating the source of the heat instead of battling it!

i used reflectix (bought it at either lowes or home depot i just don't remember which at this point) and used stainless tape (a/c type) on the seams and spray adhesive on the metal floor.. it is really easy to work with and much more reasonably priced than dynamat, etc. works really great and was the first thing i had in mind when restoring the entire interior of the car.

Ditto reflectix here, also put in tunnel insulation and the foam around the bell housing, night and day difference!
