August 29th, 2015: Foiled Forest Fire

Great idea, and you'd likely get away with it because the NSA mind control devices couldn't penetrate the foil.

...and this... works??

I mean, obviously it does (to some extent) otherwise they wouldn't be committing the resources and going to the hassle of doing it. But it surprises me!

The cabin is still made of wood underneath, and the tinfoil isn't going to be a particularly great thermal insulator, so clearly the wood inside will still heat up past its ignition point, the same as if it weren't wrapped in tinfoil.

So... is it the fact that it's a gas barrier, so the wood doesn't have enough oxygen to ignite? I'm rather curious about the science behind this!

Aha!

Nevermind... after a spot of googling, I found another link that goes into some {more|slightly different} detail. It’s not just plain ol’ tinfoil, but rather “Aluminized Structure Wrap.”

This latter material does in fact provide thermal insulation and indeed is claimed to reflect 95% of radiant heat.

Neat!

Damnit, I had looked for the details on that stuff. From the link in the first post I followed a daisy chain of sites that mostly quoted each other, and saw it called Thermawrap and Shelterwrap, which looked like brands, and aluminized structure wrap which didn't. I kept ending up with the stuff you insulate attics with to reflect infrared and give your A/C a break.

Then mrputter's post gave me hope, so I went to the link and ended up in another daisy chain but eventually I found it at Firezat. I grab a picture and the information, come back here and what's that? mrputter has a second link? Sure enough, it takes me directly to where I found the information.

I'm not a smart man.

Oh, along the way I found this on fireproofing wood buildings with Sodium Silicate on Angelfire. Told you I was in a daisy chain, including the roots.

But here it is, or at least one of them.

Looks like a heavy aluminum foil is glued to what's probably fiberglass cloth, then sewn together with Kevlar thread. Belt and suspenders.
