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.

Did you like the Dyna Mat. Also I don't think the 81 gets as hot as the early C3.

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.

The 1/8" thick high density kits really make a difference.  Dyna-Mat is about the best, but you then need to cut and fit.  The old style thicker kits make the carpet look funny.

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.

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.

You have to cut your own patterns with Dyna Mat.  It  would be nice to have it already formed and cut to fit in all the areas.

I have installed this before and the cut to fit method is easy if you use the carpet as a template. This holds true any choice of carpet / heat barrier installation.

I also use 3M spray adhesive on each surface. spray each item .... wait until tacky.... put in place.... peel back..... wait some more.... press into place.

Take your time!!! Your working in a small uncomfortable area but this isn't a place to hurry to get er done.

A hurried job will look just like a hurried job!

They do have a already cut form but not for a corvette. However it is a good ideal to use the new carpet as a template.
Thanks so much

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.

Thanks, I had most people tell me Dyna Mat was the way to go.

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, Kool Mat, and Energy Q radiant barrier

Kool Mat is crap, it is very thin and falls apart. I have found that dyna mat is thicker and is easy to install and hush mat is the same as Kool mat. 

Dyna Pad and Dyna Mat is so easy to work with and I think that it will do what is expected. I will see after I get it all back together and ready to hit the road.
Thanks

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...).

Steph.
