The problem with both glass fiber insulation between the studs AND rigid insulation outboard of the sheathing. . .
Tomorrow's (Thursday's) 6pm study session is titled, “Enclosure Fails Part II” You’ll take the first five minutes of class to answer the question alone, but if you would like to get a head-start on that, here is the assignment.
Attached, are three section details for buildings in Northern Montana. If assembly B had continuous R-2 rigid insulation outboard of the enclosure, and R-20 batt insulation in the stud cavities. . . . well, what’s the problem with that? (Hint: there is one).
*it is not necessary to have attended last week's Part I of this three-part series in order to attend tomorrow's Part II. To watch a replay of last week's Part I, which will be helpful for those who missed it (though not required to attend this week), click here https://youtu.be/aNnjpK5HVU0
