    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 for sound dampening. It made a HUGE difference! This will show you where I used it on my car.

    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. Nioco 80mil

    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=...t_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.

    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. The Thermo-Tec 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 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 turn?????

    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.

    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.
