Interior side of exterior sheathing temperature calculation. Does the calculation change when you are calculating for the roof?
In a REMOTE or PERSIST type assembly, does the calculation for determining the temperature at the inside surface of the exterior sheathing differ between walls and roof? Or is the temperature calculation the same? For instance if you used the same exact assembly at the roof as you did on the walls – would the temperature or condensation point be different at the interior side of the sheathing?
Obviously I will be using higher r-values in the roof (R-60)minimum, and (R-40) minimum in the walls.
