all that stuff comes from aspen aerogels i believe, i just got some samples of the 2 and 3mm pyrotec and the 3mm spaceloft. i was really dissapointed.
basically it looks like a fiberglass blanket/pad, that is filled/compressed with granular aerogel. just bending it around in your hands causes the aerogel particles to fall out, the fiberglass fibers too if you work it enough. looks like some nasty stuff, probably would be good for construction. they suggest laminating it to a film or something, which would help with it breaking down i guess.
well, i tested it out in comparison to my ccf. it's around twice as warm as the same thickness ccf
, then i weighed it; it's four times heavier
. the fiberglass material is the reason i'm sure, but this means that for a given warmth, it will be twice as heavy as ccf.
this sucks, i was really thinking it would be some fantastic magic material, but i don't think it is.
oh, it's also about the same stiffness as the same thickness ccf as well.
