The problem gets even worst if you have long span TJI roof joists with the
ceiling applied to the bottom chord. You <have> to vent every joist space
because they are all independent, and the vents have to be rather large
because of the long span and the volume contained between the joists.
Anyone have an elegant solution for that one?
