Basically, as I understand it, this stuff is extremely good at reflecting heat… not… absorbing and containing it. And it is relatively stupidly cheap, for how effective it is.
Like, its so effective that the industry that makes traditional US home insulation batting… basically did everything they could to make it so as few people know this stuff exists as possible.
Radiant barrier is a different insulation mechanism and is also good. The nice thing about radiant barrier is it requires very little material to do its thing. The best solution is a combination of the 2, but most insulation is still opperating by thermal mass.
Hrm.
What about:
Radiant Barrier.
