I’m in the process of purchasing an old Victorian home in Zone 4A/5A. It has a very large unfinished basement (2,000 sf and 11-foot ceilings), which has a significant amount of mold. I’ve hired a specialist to remediate the mold, which includes removing all of the fiberglass batts from the basement ceiling.
What would be the best practices to re-insulate this basement?
Reading through this:
it seems priority #1 should be to seal the rim joists with rigid or closed cell foam. Once that is done, should I also replace the fiberglass batts in the basement ceiling? Or would it be better to install rigid foam on the walls? Suggestions welcome.
And a note about the HVAC system: the home has two natural gas forced air heating/AC systems. One is located in the attic and serves the 2nd and 3rd floors. The other is located in the basement and serves the basement and 1st floor.
