OK I'm ready to frame and insulate my unfinished basement. It's about
two-thirds below grade. It's dry. I live in one of North America's colder
regions -- nearly smack in the centre in Canada. I'm going to use
two-by-fours stud walls set slightly away from the concrete wall to
accommodate extra insulation (going for R24). I'm going to vapour barrier
with Tyvek on the warm side between the studs and the drywall instead of on
the cold side. I'm planning on putting the insulation-barrier-drywall layer
right up to the two-by-ten ceiling joists. How do I, or do I put barrier and
insulation between the joists agaist the concrete. It seems to me that the
whole point of doing a barrier is to have a continuous membrane to hold in
the moist air in the house. By the looks of it if I do go between the joists
that still doesn't make the barrier continuous to the main floor above the
basement. I was thinking of finishing the ceiling of the basement with
ceiling tile and possibly stuffing even more insulation between the joists
to further isolate the basement environment from the floor above it. Is this
OK to do?
