Right. I was going to use an outer layer of something like Tyvek Thermawrap
(

outside of something like thinsulate which has an R value of 5.75. But.. on
second reading I realize that R value is *per inch*, which is not quite
going to work. Normal thinsulate is closer to R1.0.

So, unless I can find a suitable alternative -- the hexayurt is looking
like the winner. I'll have to save my geodoming for another time. :-/
