Aluminized heat barrier cloth

[AUSMHLY]

Should I be concerned about putting an aluminized heat barrier cloth under the heat sheild?

Here is a link to this product:

Reason for asking? Keoke, you mentioned about not using a metal nut as a spacer for the heat sheild. (By the way, I got some Hardibacker from Home Depot today to use).

My thinking is that you can never have too much help tring to keep the area cool. What heat gets by the sheild, should be refected away by the heat sheild cloth?

What's your take on that? Thank you, Roger

ASMH2, I do not use that particular product their #1832 seems a better choice.The Idea here is to put as much heat lossy material between you and the heat source as is practicle. Look in the archives a number of products have been identified in the past.---Keoke

I found this place to buy my aluminized heat barrier cloth. It was the least expensive price I could find at the time. https://www.aircraftspruce.com/catalog/eppages/heatbarriers.php
They also sell a mat that I installed under the driver's side seat and carpet.

Hi ED, Welcome to the forum. How did this product perform in your car.?---Keoke

Hi Keoke, I don't know how much it helps yet as I don't have it all the way back together yet. I haven't driven this car since 1971 but I can remember it being hotter than h... in the summer. I am convinced that anything that I can do to insulate from the heat will be worth the time and money. I will let you know how it works once I get it back on the road.

We have had a couple of threads about heat proofing, and one question I have meant to ask is does it matter if the "shiny side" is facing the source of the heat? Since my BN4 did have the underseat heat shield, I want to be extra sure.

HI Patton, having the shinny side facing the heat source will provide the best reflective,Radiated, heat loss which reduces the materials requirement to provide conducted heat loss.some of the materials have shinny surfaces on both sides.--Fwiw---Keoke

Hey Keoke- I tried to do that with the Dynamat Extreme, but every time I tried to push it down, it just stuck to my hands. /ubbthreads/images/graemlins/confused.gif /ubbthreads/images/graemlins/confused.gif /ubbthreads/images/graemlins/jester.gif

Well Greg, I guess you should have cleaned your hands before you tried to install the Dynamat. He probably didn't read the instructions---Keoke-- /ubbthreads/images/graemlins/laugh.gif

Patton, Before I bought the thermo tec product, I read some info on one of the many sites that sells the stuff, or perhaps it was on the manufacture's site, I can't remeber. Anyway, they say the product was most efective blocking radiant heat when the aluminum side, ( oposite from self stick side ) , was pointed at the heat source. They also say if you have to mount it on the oposite side of the firewall from the motor then the aluminum side should face
away. It apparently works better in reflecting radiant heat as oposed to being used as an insolator. In any event, if you get the self stick kind, the decision is made for you. Keoke is right, it really depends on the product that you are using. I bought a insulating matt from the same place to go inbetween the floor and the carpet. The real shiny side went down towards the floor, the less shiny side , ( aluminized ? ), went up towards the carpet.
