Thermal barriers for cabin - F-Body Road Racing and Autocross Forums

I'm wondering what some of you may have done for thermal barriers in your cars. I have removed my AC in the name of weight reduction. The AC never worked very well anyways (would need it on HIGH for 15min to even break the heat off of you).

Car is in CAMC and full interior (without back seat) 95 Z28. I like to drive it a lot on the street and the heat is what will be a killer. Heat and interior cabin noise is a recipe for headaches (for me) after only 10min of driving. Plus my wife won't come with me anywhere (IMG:http://www.frrax.com/rrforum/style_emoticons/default/smile.gif) and I like her so....I'd like for her not to complain.

SO, I've been looking around and it seems there are either tar-like material that are peel and stick, there are loose mats you lay down with foil backings and there are some you spray down. I'd prefer to avoid the spray on and peel/stick version since that crap gets messy.

Ideally I find some stuff I can put under my carpet that just lays there to help keep heat out.

Anyone have suggestions/products to look into? I assume some of you get hot on the road course.

Peel and Stick: Dynomat-ish products
Spray on: LizardSkin...Eastwood has a version as well
Loose mats: Not sure of the product being used https://www.youtube.com/watch?v=SFIfnA08--g

Since making this post I spoke to second in command at DEI and for my application they suggested their "work horse" product Floor and Tunnel Shield II. A thin fiberglass peel and stick with a foil backing. He suggested putting it up the firewall as far as I could, down under the seats and above the trans. Adding ice packs is a little out there (IMG:http://www.frrax.com/rrforum/style_emoticons/default/smile.gif) Car still has HVAC controls and a blower motor so air can be moved around. I've thought of a Lizard Skin approach, but DEI made a good point that if you need to cut/weld, things can get messy and is fairly permanent. So many products out there with what seems to be very little data to support claims. Many on Corvette Forum have praised the cheap HVAC ducting insulation Frost King which is another peel and stick product to use under the carpet. Both Frost King and DEI won't add much weight either.
