For others interested, hanging the floor systems allows a tighter envelope, and easier, more efficient insulation details.
I assume you are talking to me as I don't see a Dale in this
thread. We considered this but the builder/designer elected to go the route of building a floor deck on top on the walls. There were some issues with material usage that made this work better. Plus this does make it easier to run electrical into the walls. However we are having
spray foam insulation applied to the inside all the rim joists after all the mechanical's are in which will give us close to the same thing, plus it fills any cavities around items coming through the rim joist (electrical supply, gas supply, furnace &
water heater vent ...)
Regarding panel usage, you can save a lot of money if you design to the material. I don't know if this is the case with all SIP manufactures, but for Insulspan (the one we are using) the panels come in 8' x 24' or 8' x 20'. So in our case most of the first floor walls can be made out of a 8' x 20' panels (think cut in half to get 2 - 8' x 10' pieces) with very little waste. From the top of the basement wall to the roof is 14' (1 foot for the first floor deck, 10' for first floor walls, 1 floor for the second floor deck and 2' knee wall to give a little more head room on the second floor), which is more than half a panel. If we went with 8' ceilings in the first floor we could have used 1/2 of a 24' panel and hung the floors. But my wife wanted higher and Happy Wife = Happy Life so we couldn't hang the floor.
