Exterior wall assembly in NW Iowa
We are building a new house with geothermal heat and a lite form basement and lite deck first floor floor. The first floor wall assembly is board and batten cedar siding on Tyvek drainwrap on 7/16 OSB on 2x6 girts at 30" oc with 2x4 vertical framed walls. We have R40 SIPs panels on the roof under a metal roof. We are planning on 2" of closed cell insulation on the walls. I have been reading about including batt insulation as well and was wondering if anyone had a recommendation either way?
We are also including a fresh air exchange in the HVAC system.
