Heat Shield

[IowaBen]

I'm looking into what heat/sound barrier I want to use inside the cockpit. Does anyone have any recommendations (PN's would be helpful also)? Just looking at Summit's site, I'd maybe go with Dynamat 11101 or Thermo-tec 14620 (for a self adhesive type). I know I need to keep it thinner to avoid eating up space, but how low can you go? What's worked well for everyone?

Thanks!

Oh, and how about EZ Cool's product?

I used EZCool. It is a thermal barrier. The really nice thing is that it is lightweight. It is not self-adhesive, but very easy to install.
From EZCool:
Q: How thick is this insulation?
A: This insulation is approximately 3/16" thick.
Q: What is the R Value?
A: Down = 13 Horizontal = 9.6 Up = 8.1 This is better than 2" of fiberglass insulation.


Dynamat 11101 looks pretty thin(1/8") to me. I would go up to a thicker one if I went that way. The sound deadening properties are pretty much a waste on a car with the exhaust 2 ft below your ear. It is also single layer, so will likely not be that great of a thermal barrier. Also, from their web site "For best results, install Dynaliner over Dynamat." So it looks like it is designed to be an add-on product.


Oh. For most of us, we have only ever used one product. So not a lot of us can give you a comparison. There might be a couple guys out there that have tried different products.

I used the Thermo-tec product that you noted and was happy with it.
I would definitely recommend applying it to the footbox prior to putting in your pedal box.

I used hushmat from summit on all the aluminum panels to help with the drum sound

With that and carpet the heat is not to bad I found that a lot of heat came in around the front fenders at the door hinges if the seal leaked

I agree that it doesn’t make much difference with the sound levels with the wind, road and exhaust noise and wearing ear plugs I cannot hear the horn above 60 mph

I used Dynamat. Easy to install. It does help with the heat fron the engine, but at speed it is the wind and exhaust noise are the issue. I wear earplugs all the time.

I'm planning on using Lizard Skin

Vote #2 for Thermo-Tec. It is easy to cut and apply, it works great, You can buy it on Amazon, and it is cheaper than others. I put it everywhere. It really makes the cockpit sound solid. I even put it inside strategic parts of the body that you can't see to make it sound more solid.

Another satisfied thermo-tec customer here.
Also second the above recommendation to apply it to the inside of the footbox panels before installing them.

What is the average Square Footage needed to insolate a Roadsters interior?

[jlfernan]

About 40 sq ft for just the interior, more if you're doing the trunk.

How thick is this stuff? Do you need to glue it or is there a sticky back already?
My main concern is heat...would this help?

Thanks,
