I live in Denver, CO (relatively low humidity). I am trying to finish the basement which already has a vapor barrier on the walls stretching from floor to ceiling joists. Between the joists I can see and touch the fiberglass insulation. Should I extend the vapor barrier between the joists? I intend to finish the ceiling as well and the exposed part would be above the drywall level. Additional info:
- basement has well windows, therefore joists are above ground level.
- kb home built in 2017
- Furnace/boiler located in the basement.
