you could use Tuff-R, but it would be labor intensive to install
between studs. also, it would be very difficult to fit around all the
obstacles one encounters, like wires, pipes, etc. it also would be
hard to get a good fit to the studs (though you could fill any gaps
with spray foam. if you really want a good job, use fiberglass, and
then cover the wall with tuff r. tape the seams with red tyveck tape
for your vapor barrier (caulk to floor, etc.)
