Do you happen to know what the thermal conductivity of BX-250/265 spray
on foam is?

Nope. I don't think anyone uses either of those except NASA. (And my
last efforts at getting info on ET foam around the time of the
Columbia incident with my NASA contacts got me nowhe I got
incorrect info).

However, I do know that it's a polyurethane foam, and a good
high-performance polyurethane films can be as good as 0.03 W/m-k,
which is on the same order as aerogel.
