Heat Shielding, do you use it?

Title. How come this isn't more abundant in builds? Does it serve a purpose? I'm talking about that sticky layer stuff, either that gold shielding or just standard looking OEM shielding being used on the firewall in the engine bay. I was looking into it and there's not many builds using it. Is it just tacky or is there a huge drawback like using header wrap (looks cool but holds moisture and kills your header). Thanks. I need to lazy patch some rust holes in my transmission tunnel and was gonna use aluminum tape to temporarily enforce the area, but I thought heat shield stuff could do too.

Race cars are worried about weight, not noise. Most builds you see are about improving performance. As I’ve gotten older, NVH has become more important to me. In the same car Ive had for 35 years, in the last 5 years I’ve done Dynomat on the floor, a lighter weight sound reducer in the doors, and redid all the door and window seals. I also redid the exhaust system to make it more quiet. As far as actual heat shielding, the only thing that really had it are my starter wires that run near the headers.

Thermal barrier coatings are lighter and can have more heat deflection than a heat shield. Usually just cost more and don’t help much or any with noise.

People don't use it because when you are trying to make your car faster, weight is the enemy.

I think most people don't do it because it's a lot of effort and sometimes for not much of a return. I did it on a Toyota picking and it may be helped the heat like 5% I still never had to run my actual heater in the winter lol.

I mainly use it on plastic stuff I don't want to melt. Maybe it doesn't get more use because people adding more heat with a turbo build or engine swap are always over budget?
I've actually used the gold tape on a couple motorcycles for stock brake reservoirs and batteries close to the exhaust too.

I did in my BMW 850, Held up great

If your referring to the dynamat stuff it works great! An old project cavalier I used to have, I bought the Amazon brand and applied it to the interior. Reduced noise and some heat. Buy the metal rollers and your life will be so much better, future you will be so happy!
The only downside is removal is a pain in the ass. You need dry ice to remove it.
If it were me I would do the Pole Barn Garage treatment. License plate, self topping screws, and sealant (roofing tar is my preferred choice). Then dynamat over the top.
