Intro: HexaFrame 2x4 Shelter
Inspired by many time tested human building concepts.
Very wind resistant, high strength, and material efficient.
Designed to be sheathed with 1.5" concrete skinned blue/pink foam board (or many other coverings).

Now, on to the "story"....
I happened to be messing around with a hot glue and screw technique with 2x2 lumber when I got a brainstorm.
People at Burning Man have been using foam board Hexayurts for a while....why not make this idea into a *real* structure?
Gonna need a frame for that..
Step 1: A Look Inside
A look at the frame and it's subsections.
Step 2: 2x2 Version
This is the 2x2 version of the HexaFrame.
It's designed to have dense pack cellulose insulation blown inside the entire frame.
This means 8" thick, cheap insulation.
Very little thermal bridging (heat leakage) through the wall.
All 2x4 and 2x6 walls leak heat through the wall studs. Covering the building in foam board helps to stop this.
Most American homes do not have foam board covering.
Typical stud construction is bad anyway. It's done only because it's cheap and it's all the builders understand.
This design is strong while keeping heat leakage to a minimum.
It can also be pre-fabbed and bolted together at the build site.
Carry it into the woods or wherever it needs to go.
