I've read a number of posts here about basement insulation.
I have a 1964 split level near Denver, in which I'm remodeling the lower level. Current foundation and exterior walls have no insulation, other than batts in the bays.
Below is the cross section I'm thinking about. Today, only the foundation wall and 2x4 wall above exists. I was not thinking of filling the void with anything to promote breathing. There some moisture in the foundation, but nothing excessive and no bulk water. I am going to do some remediation of that through a sump pump, excavating and waterproofing in select areas, and whatever can be done on the exterior with compaction, clay top, and drainage away. I'm not overly concerned, but do want to ensure it could dry to the interior, given the sill plate sits directly on the foundation wall (no gasket).
Do you have recommendations to improve this approach?
If the building department requires me to fill the void, what is my best option?
Thanks in advance!
