I am installing new carpet in my 68 convt. It has the jute padding in places. But what I need is something to put down first that helps keep the heat out. I have tried several so called heat kits under the old carpet but it hasn't helped much. The floor gets pretty hot, and I do have a heat shield over the header pipes and an insulation barrier on the underside of the floor. What do I need to put down under the carpet for my heat problems. Maybe NASA Space Shuttle Heat Shield Tiles.

I'm interested in what experiences people have had with various products as well
I wanted a Corvette my whole life, but I never dreamed of all the wonderful people I would meet because of it!

I used a Heat Barrier/Underlayment kit from Volunteer Vette. Some kind of ceramic cloth with a foil backing.....$150.00. I also added some dense foil backed insulation that I picked up at home depot behind the seats and under the seats in places that it didn't effect the fit of the carpet. I just used spray adhesive and put it over the top of the kit. I also made sure I didn't have any little holes in the firewall and all my grommets were in place like around speedo and tack cables. It's pretty cool in there. No complaints from the wife about hot feet.
I just finished working on my 74 for hot feet! Mine would get that hot after about an hour that I couldnt stand to drive in. I purchased a product called Lizard Skin from Summit Racing. I removed the interior and sprayed it on with a special gun they sell. I dont think a regular gun would work. Anyway I made my first drive to Carlisle Sunday morning since completing this and there was no heat at all. I actually had to turn the heat on, on the way there because it was just in the mid 50's when i left. I am very happy with this. I also finished off the job by putting a layer of the home depot bubble foil wrap on top between the coating and carpet. It works great. If you decide to go that way let me know and you can borrow the gun I bought. However I will be spraying the 72 sometime in September as well. Rodney
Thanks, I will look up the lizzard skin. Thanks for the offer. I think I only have a two to three week window to get something, while the interior is disassembled. I have used the bubble wrap with foil before and it did not work for me. Also the foil wrapped jute which didn't help all that much. I am talking TEXAS HEAT. 100 degress plus and that isn't on the asphalt.

I did the Dyna Mat throughout the car a few years ago. Up the firewall all the way back to the rear panel. I just bought a kit that was all sheets. It wasn't too bad cutting and fitting. Just have a good small hand roller to smooth it out. It did make a big difference in lowering the heat and cutting down on some of the road noise. One of these days I need to line the door shell with the stuff. I'm not looking forward to that. lol.

Right now my 68 is all apart and I have a chance to do anything. So I might consider the door shell too. I had ordered some heat barrier out of Corvette America, but since then I have heard so much on the Dyna Mat that I think I will order from them. I wonder if I could overlay both of these, without causing problems with the carpet fit.
i just had my 81 done and the guy who installed it said it came in a kit allready precut for my car and i ordered the kit for my doors and my tops also i have fiberglass tops on my car and the difference was worth it and the road noise also
The Corvette Restorer issue winter 2009 had a comparison and HushMat did the best job for heat reduction. It was compared to Corvette Central ceramic heat barrier, KoolMat, and Energy Q radiant barrier

Not a fair comparison; hushmat is for sound insulation; not heat.
Anyone has experience with products other that DynaMat or lizard skin
(sprayed stuff is a little too permanent for me...) for heat? Roofing
material from home depot perhaps? I don't feel like paying for the
"Dyna" name... and I can cut my own pieces; looks like everything
"pre-cut" is twice the price.
I'm really looking for an affordable heat insulation solution. I'm
assuming a molded carpet that has a jute will be enought for the sound.
Our C3's are not all sheet metal; so they don't produce as much
vibration noise to begin with (I think...).
