Default Heat Barrier / Underlayment

I've seen a product advertized for heat barrier/underlayment that is a ceramic cloth with foil backing that says it will lower cockpit temperature by 50 degrees and block heat to 2300F. I was thinking about using this in the passenger area with standard underlayment over it and then carpet on top. For the rear, Dynamat and carpet. This will be in a '70 BB vert with 2 speakers in the rear and 2 in the kick panels.

Have you used the ceramic cloth product? If yes, do you like it and what did you top it with? Should I use Dynamat here too instead of regular underlayment?

Other sugestions...

I used something like that product on the underside of cockpit to help reduce heat from dual Cats (LS1 conversion) - then used the microspheres (Wicks) mixed in paint on cockpit interior. Then the foil / bubble stuff from Lowes (reflectix I believe), then carpet underlay and carpet.

The ceramic/foil stuff I used was fairly pricey - so I only used a few sq feet underneat floorboard. The microspheres seem to work pretty good - although I did not do good before/after testing - and are pretty inexpensive.

'though I've seen it priced less ($20 per roll) at car shows and swap meets.
I used it in my '69 Camaro last winter and it works really good.

I used one of the kits (I think it was from Ecklers) and like the product alot. I first put down Dynamat Extreme and then put the ceramic/aluminum heat barrier down before putting in new carpet that already had some sound deadening attached to it. Car is quiter and cooler than it was before.

I'm going to use this pricy stuff on my '80 restro. If you are having a hot cockpit problem, try putting a foam block around the top of the trany, between the the hump & floor pan area. That will stop hot air flow under the center of the cockpit. The foam conforms well to the contours of the equipment. Foam block is easy to install/fit into place. It seals off the hot air nicely and allows the hot air to be redirected off to the sides & out.

i have used the ceramic cloth it seemed it to help didnt do before and after and have been told that the foam which is missing on alot of cars but that is why the GM people put it the to block the heat from going down the tunnel

I checked this out on line and there was no distinction between a standard and auto trans so am I right to assume the foam will work on either S/A?

It should fit on either. It's big enough, where you have to force it into the gap with your fingers or broom handle. You don't need glue like they used at the factory; it's a tight fit.

Thanks for the tips guys. I'll slide under the car after a bit and see if the foam block is there or not. I'm guessing it's not.

I just took my wife out yesterday after a complete interior removal. She said her feet, with socks, were not even hot when she put them on the firewall of our big block 69 coupe. That was worth all the time and money to me.
I stripped the interior, applied a layer of DynaMat Xtreme from the firewall to the rear storage and the top of the rear storage as well. It's only 55-60 yesterday, I know, but last year that thing burned us up. I use the stock insulation, then carpet from Stock Interiors. Great carpet kit, by the way. I don't even have the foam collar, the underside insulation, or the steel panels that go underneath yet. The DynaMat has proved itself to me, thru my wife's satisfaction.
If Momma ain't happy, ain't nobody happy. If Daddy ain't happy, ain't nobody gives a damn!!!!!
