"Important safety notice. Please do not build hexayurts out of any
flammable material. In the past, people have built them from non-fire
rated materials including polyisocyanurate insulation (Tuff-R from
Dow, often sold at Home Depot.) I do not regard that as safe if the
building is exposed to sources of ignition like open flame, or mains
electrical devices. Any non-fire rated substance should not be used
for camping, and is generally suitable only for demonstration
purposes."
I haven't found a retailer of Thermax (much less Thermax HD), which I
presume is more flame-retardardant, anywhere. Google Alerts produce
nothing. I haven't found a distributor of Thermax that will let me
order a "package" or less. I can get a dozen or so "packages" of the
stuff (a package has something like 20 panels) minimum order.
Bill, we're working on it. Tuff-R, as used in previous years, just... it *burns*. And not in a good way. Thermax and Thermax HD are very different. Other options - some of these heavy industrial cardboards. I also have a lead on some really really good materials and should be picking up prototypes of those materials in a couple of days...
So, yeah, I'm really sorry this stuff isn't as easy to find, but I really am worried about Tuff-R on the Playa. I don't want anybody to be the first person to get their Hexayurt burned down around their ears to dramatic effect, you know?
Maybe a group buy of Thermax HD?

I'm willing to take the lead on getting a large Thermax buy for San
Francisco Bay Area Delivery (say, San Jose). I'm guessing we'll need
about ten others to make it work.

Bill, that's great news. We've got some other materials that may be becoming available which would have similar, possibly even better performance, and are a bit easier to get hold of (potentially.) Let's give it a couple of weeks and see if we can't get something solid sorted out on that.
I really want this to be a big year for Hexayurts at Burning Man. I hope a lot of people have been exposed to the idea and want to build!

Ah, this is not good. I called 8-10 possible sales offices, for Dow
(mgfr of Thermax) and for Weyerhaeuser (distr of Thermax), and finally
found someone who knew the situation. There are no manufacturing
plants for Thermax or Thermax HD West of the Mississippi. This is due
to lack of demand. The way Thermax comes out here is in full truck
loads, which is 30 "units." The number of sheets per unit varies by
the thickness of the sheets. For one inch sheets, there are about
2000 on a truck. So, in order to put together a buy we would need 100
users. That is a lot of Thermax.

It would probably be helpful to know where such shipments have been
made recently. Did you get any information on that? Maybe you could
provide us with the contact info for the person at Weyerhaeuser that
you spoke to....
My husband does a/c sheet metal and says here is another option called
'duct board'. Unfortunately, one side is fiberglass insulation, so
that would require covering it. He's going to check around at some of
the supply houses and see what he can find.

It would require some sort of framing, but it's fire resistant and has
an r value of 14.
One role for $300 would create a structure bigger than the large sized
hexayurt.
Right now I'm looking into how a frame could be built using bamboo in
a geodesic dome. Then you would just make panels using the Prodex and
tape them together over the frame. However PRodex is light, so many
different frames would probably work.
I think that's the same stuff I have on my windows to block out the
sun; if so, it's no thick enough to stand on it's own, but it is a
really good insulator.
Since my husband works in sheet metal, he of course, wants to frame a
hexayurt out of metal. But that defeats the purpose of having a
lightweight structure.
