those gold/silver emergency blankets: do they really work, and how?

It’s a thermal mirror. A regular mirror won’t reflect the heat back at you the same. It’s the property of that thin ply of space age metal alloy developed for being light weight and deflect radiant heat away from a craft. In essence you can use it the way space crafts use it to stay cool if you use it to build shade, too!
Campers use this as a cheat mode in imaginative ways. Use it against the backing to reflect the campfire heat down onto your sleeping mat.
Use on opposite side of fire so the side toy aren’t on is reflected back at your camp tent instead of radiating away into nowhere
The material itself doesn’t get warm usually. It’s cool if you touch it but of course it can hot if you guest it
*Maybe not an alloy and just a composite of two materials that don’t fuse or anything
