View Full Version : Heat and Sound Barriers

I am about to order some heat and sound barrier material for my aluminum panels. Looking for some do's and don'ts or any other advise from other users.
I am about ready to hit the order button on the Thermo Tec heat and sound, peel and stick barrier. I plan on using this inside of the foot boxes and any left over, maybe on the cockpit floors and trans tunnel. For the rest of the car, seat back, trunk, etc I think I want just the sound barrier. I like the thin stuff, no need in adding weight. I will be checking to make sure the carpet will mount on all of this.
I am shopping Summit. They seem to have a good selection and I am used to dealing with them.
If anyone has a figure for the amount needed, it will be appreciated.
Please feel free to make suggestions, thanks.

I used Noico 80mil (https://www.youtube.com/watch?v=bkbYC-jkqrg) for sound dampening. It made a HUGE difference! This will show you where I used it on my car (https://www.youtube.com/watch?v=8NJjqvzKpHk).
I got 2 boxes, and used 1/2 of a box on my car. I still have an entire unopened box (somewhere) that you are welcome to have if you wish (or the rest of the opened box) for the cost of the ride.

Otherwise, for thermal barrier I used EZ Cool from lobucrod.com used mainly on my footbox walls.

Regarding the amount, I used 18 sheets of 18"x32" (72 sq ft) Dynamat on my car. That covered the entire cockpit (including back wall & sides), trunk, & firewall. I would guess that half of what I used would do your foot boxes, floor & transmission tunnel.

I used the sprayable lizard skin and it’s crazy light. The gallon can actually felt empty. Looks great and is very thin and easy to apply. It’s also water based so there is no bad smell and it cleans up with water.

Thanks for the information. I have decided to go with the peel and stick line. I have not read anything bad about Lizard Skin, just did not want to deal with the taping and clean up. It sounds like what I have lined up for heat protection and Dad Of Three's offer, I should be good.
In reading other threads, it sounds like it all works, just differences in brands and locations of installations.
I am still open for advise on the job. Thanks for making this easy.
I used Thermo-Tec on the inside of my cockpit. I used a total of 4 (3'x5') sheets (60 square feet). I didn't do anything in the trunk. I've installed my carpet over the top the Thermo-Tec using 3M S77 spray adhesive and it sticks just fine.

I used Lizard Skin ceramic for the thermal barrier and then covered that with Dynamat for sound and vibration dampening. Has worked well.

Here are my thoughts.
Heat barrier - this is what you are looking for.
Sound barrier - An open car with a sidepipe two feet from your ear makes it wishful thinking. There is not much under the floor or in the trunk that makes noise.
I used EZ-Cool. Heat barrier and light weight. Big power and light weight is what a Cobra is all about.

Would probably never hear any sheet metal noise, but like the idea of the sound deadening on the aluminum spans.
Here is a quick demo of what the sound deadening products accomplish.

Yes, these are loud open air cars, but applying a sound dampening material will make the car sound more solid. That's my $0.02.

I just went with .3" thick Reflectix heat insulation under the carpet for the full cockpit interior. Gave a more solid feel & quietness to the aluminum. It was still functional in reducing heat from the drive train. Nothing you can do about heat from the sun without a roof.
Outer panels facing a heat source were covered in ThermoTec.

What do you guys think about using this product from Summit Racing?
https://www.summitracing.com/parts/sum-879006
It appears to be similar to what most of you all used, is made in the U.S.A. but is pre-cut smaller size may help me better deal with the installation process because of my boogered up primary hand.
The total square footage is:..34.56'

I'm sure the product will be fine, but I'm guessing you'll need a second package to cover the entire cockpit. Free shipping on that product, so I'd order only 1 for now. If you're willing to spend a little money to minimize the cutting, get one of Breeze's insulation packages. https://www.breezeautomotive.com/?s=insulation&post_type=product
As for smaller pieces, you're definitely on the right path. I cut my Dynamat into much smaller pieces than the 18" x 32" provided. I also used the scraps to fit the irregular shapes of the aluminum. I used a straight edge & a box cutter for the aluminum, and completely dulled several blades in the process.
Last thought: be sure to get a brayer (a hard rubber roller used to smoosh the insulation onto the aluminum).

I can't recall what the dimensions were on some of the panels, but I'd measure first to make that size will cover the largest side, or you may end up cutting more due to the smaller pieces.

How do these products hold up to getting wet if it rained?

They all hold up well to rain. It’s more of a application and effectiveness that differentiates them.

I used AL's Heat and Noise spray, similar to Lizard Skin, then added Thermo Tec. EDITED 7/10/19... I used Thermo Guard, not Thermo-Tec
The Thermo-Tec (Thermo Guard) is a sound and heat barrier with foil on ONLY one side (install foil to heat side... i.e. down). I also added AL's and Thermo-Tec (Thermo Guard) to the trunk. Was it needed? Maybe help keep things I'm carrying cool. Supposed to deaden sound better than foil on both sides. Is it true?????
I also did not glue it down over the tunnel. I used the old fashion carpet washers and screwed it in place. Turned out to be a good thing. Had to remove the tunnel cover to fix the trans leak (twice). Made it easy to remove and replace.

Can Lizard Skin or Al's Super Goo Be Rolled On Like Herculiner?

I've brushed Lizard Skin on small pieces or where spraying wasn't practical or I didn't feel like getting the gun dirty. Never tried rolling it. It's hard to get the proper thickness though. Need to wait for it to dry and hit it with several coats. The advantage of spraying is you can get the desired thickness with several passes in one session.

Just letting everyone know, DadofThree was generous enough to give me his left over insulating material. It arrived today and looks quality.
Thanks Dave, DadofThree.

I was surprised to see that Thermo-tec needs to be installed with the foil down. Does this mean you don't use the adhesive backing and just use spray adhesive to glue it down on the interior? I was just about to buy some of this for my Gen III Type 65 coupe but maybe it is not the right product for me. Have others used it on the interior with the adhesive down? I was wanting to add this on the inside and then cover it with carpet.
Below is what I was thinking of ordering.
Thermo-Tec Acoustical & Heat Control Mats 14620 https://www.summitracing.com/parts/the-14620/overview/
Edit: I ended up ordering the Summit branded ultra heat and sound insulation. I read too many reviews about the Thermo-tec adhesive melting and running down. I'll let everyone know how it goes since it does not seem to be recent reviews of the Summit ultra heat and sound insulation.

I'd actually be surprised if someone installed it with the aluminum, face down, in the cockpit. Where did you see that done? All the interior photo's I have ever seen of insulated cockpits, using an aluminum faced material, show the aluminum face up. I know that seems odd, being the aluminum acts as a "heat reflective" surface. That is how it would work, if placed in the engine compartment side on a vehicle's firewall, or the outside of the footboxes, tranny tunnel, etc., on the roadster..
The particular product you are looking at is only 1/16" thick, so it has no insulating quality's whatsoever. It is strictly a heat reflector. I wouldn't use it on the inside of the cockpit myself.
Dynaliner would be a far better choice. Heat and sound insulator, waterproof, etc. It works as a great backing to the carpet as well. Use black automotive silicone to adhere the carpet to it.
Various thickness's available
http://www.dynamat.com/brands/dynaliner/
This product might be a good alternative as well. It's thicker then the one your looking at, but not as expensive as the Dynaliner.

Thermo Tec installs sticky side down, foil material UP! Thats how its designed and has been used in some thousands of hot rods and street machines over many, many years. The material, although thin, is very, very dense and does very good at protecting from heat and sound. Good for 2000F radiant and 300F direct. Used on interiors only, not engine compartments.

I purchased the Thermo-tec... EDITED 7/10/19.... I used Thermo Guard, P/N 14130 & 14132 (size difference) heat and sound deadening. It has foil on only one side and does not have adhesive backing. I originally was looking for sound deadening material because I installed a radio. The products I looked at were felt on both sides. Then I found the one sided foil, I felt it would suit my needs. At the time, I read that the foil should be to the heat side.
I installed it on the inside of the cockpit, foil down... to the heat side, felt showing. I have seen several people use similar products with foil on both sides, thus you can see foil in peoples pics. Not sure how many people have used the one-sided foil product vs two sided.

Ah, different Thermo Tec product. Understood. From their website, you used Thermo-Guard, whereas I used Suppressor Acoustical & Heat Control Mat. Didnt know they made different stuff... my bad. Yours probably adds a nice little padding under the carpet. Mine does not. Yours gets glued in, shiny stuff down, mine gets self-adhesive peel n stick, shiny side up. :)
