Just came over this:
They now do not recommend "raw" foam sheets and the tape used
for connection:
http://www.appropedia.org/Hexayurt_Safety_Informationbut the design is still valid for noneasily flamable materials - plywood,
mini-SIPS [Estimate ~1-2in foam core and less flamable skins.] etc.
Say, 1&1/2x1&1/2 perimeter frame, foam core, then skin material.
Use those for all panels, including the bottom/base [Or maybe
increase that thickness a bit on that.],
The sixfoot looks like it'd be "roomy" for one person. The point-to-point
measurement is 8foot, so that'd allow room for sleeping. The sixfoot stretch
would be quite roomy as they say it's a bit 'tight' for two:
http://www.appropedia.org/Hexayurt_schematicsThey would be 'larger' than most single occupant shelters, as shown on the
thread so far, but still not much larger than a TD or TTT. Bolt-together mini-SIPS
would work, especially if some of the panels are hinged together and fold
flat for transport. This added fabrication is not as inexpensive as just the straight
sheet material itself but it would give much longer life in use and more useful
comfort/performance.
The basic design was done to use the standard 4x8 sheet size as the base
unit to allow full utilization of those with minimal waste. You could dimension
it somewhat smaller but it'd still cost what the full panel one would - unless
you could figure out a way to utilize any trimmings in subsequent units.
