The Interior finish is showing real promise.
The exterior too!
"The Trail Begins Here"
The insulation is mechanically held (not show) by flexible wires to the warm side surface allowing a 1" air gap at the bottom of the joist bay. Ventilation is accomplished with screened holes in the sheathing.
Plywood was installed to "critter proof" the insulation.
The Vaulted Main Floor area gives a spacious feel and affords many finish possibilities. We will likely use Pine T&G on the Lid and some Local Doug Fir for Wainscot, Panels, Base, Case, etc.
