Re-insulating/finishing a basement? options?
I think your best bet is spraying foam, then install studs and drywall over that, leaving the spacing of the studs free and able to breathe. Fully insulated walls or vapor barrier and similar practices is known to cause molding since the moisture will have no way to evaporate. So do not use any vapor barrier. Normally it should go underneath the foundation or on the outside wall.


Look what insulation and vapor barriers do.
