Yes that is correct but we did not have to worry about that problem.
They are going with SIP (Structural Insulated Panels) for the walls and roofs for that very reason to get more insulation.
The walls are 6 1/2″ with R-40 insulation and the roof is a 8 1/4″ panel with R-50 insulation.
As far as the wind attachments go that i don’t know yet as the blueprint is at the Engineer (because this one requires a structural engineer stamp). But the Sip Wall Panel company will be calling out those attachments per Manufacturer and State code requirements.
