Hey Tim ~ I'm also concerned with safety and look for materials that really do the job well.... and with a safety margin I'm comfortable with. The theoretical fire-related risks in a yurt with aluminized interior surface are scary with the lens effect and other concentrating potentials. Even - or in some hypothetical cases - without the foam board itself catching fire, just having any substantial amount of stuff burning in a heat-concentrating structure can get pretty intense. Thinking of keeping any flames out of there, myself. I like to cook but might have a separate, safer place to do it... also experimenting with more serious electrical power and using non-flame cooking stuffs like induction - which looks amazing btw.
It appears to me that a well-constructed H15 (which, to me, means mitered corners - which really improve the integrity of tape joints & carrying through the structural properties of the skin over the foam, and also means well tied down and weak points like doorways reinforced) made => 1.5" thick board should stand up to an acceptably high percentage of possible weather on the playa. I don't think any weight difference is practically significant. I can lift a whole H15 either way if it's a package I can handle. I'm playing with Hexacomb board. It's quite a bit more rigid but needs waterproofing and possibly some help with insulation & reflection. It's pretty light and about half the price of HD. Also playing with hybrid systems - board captured by EMT TinkerToy. Hard to price that kind of stuff though... more of an art statement you live in... Re group buys, Home Depot might special order HD in some quantity, but probably not necessarily a huge amount, so I'm not counting that as much of a barrier. Costs a bit more but like you say... Either way, I can do the kits and accessories. ~ Dan On Mon, Jun 9, 2014 at 9:24 PM, Tim <[email protected]> wrote: > We'd be interested in a group order as well. > > I'm somewhat new to yurt building.
