So many variations and analysis done this week. The end result is a simpler and cheaper system. Because it is now cheaper, for some reason we added another layer of carbon fibre weave...
We dont need this extra layer, as we already are stronger than building code requires and certainly superior to traditional construction.
In fact its one extra layer per side of the sandwich, so 2 layers per panel total. Strength, stiffness and torsion (bracing) has increased significantly.
I think we want this system to be so good, and so much more superior that keeping the overall price very similar to traditional construction yet having a system so much better is kind of a nice target to have.
