New construction in S.E. Wisconsin with partially exposed walk out basement. The concrete floor will be insulated and also have thermal break at edge. I would like to install a passive radon system with 4″ pvc extending up through the roof.
I am looking for details with continuous insulation from under slab up to and including both the stud wall at exposed side and 2×4 furred out walls against the poured concrete walls while locking in potential radon under the floor to be vented outside.
