Hey guys. Just wondering what kind of insular should I put up over this vapor barrier plastic? I plan on leaving the area wall open like in the photos so I can keep the sump discharge line warm to the warm basement air as the basement is the hottest place in the winter a grizzly could hibernate lol. Already had the sump line freeze when it was fully finished in this area and had a mess in that wall prior to tearing it all out, so a little insulation behind the PVC wouldn't be a bad idea I don't think. I'm thinking some R30 up to the subfloor past the rimmer and calling it a day as the pipes will benefit from my warm basement temp and I can monitor it throughout winter. Spray foam is out of the question because per code, id have to have that drywall barrier reinstalled and i don't want drywall in this area. Any ideas?
