Conditions: Balloon framed construction, house built in 1930, Southern Connecticut region Does installing a fire-stop or Fireblocking where the sill plate and rim joist meet, block airflow and promote rot in the walls where moisture may get trapped?
I have heard conflicting views as this may have become code in some areas, yet will create the risk of future rot in the walls.
I own a 1930 Tudor influenced , 2 story colonial in Connecticut. It was built using Balloon Framing construction, which left open voids on all sides, from basement to attic. I recently framed-in the basement and finished it as a living space. I inserted pink insulation in the “Balloon” cavities as far as I could reach above the sill plate, and closed the balloon voids with panels of drywall, to create a fire stop and minimalize heat escape. I am not sure if this will stagnate the airflow and promote rot in the walls of my home, or if there will still be enough airflow to let moisture out of the balloon voids behind the walls? Thoughts? Suggestions?
