Any way to keep the second floor floor warm in a balloon frame?
Have an old house with balloon framing. Cellulose was blown in a last year. We were hoping, that among other benefits, that the floor on the second floor would be warmer.
In a balloon frame house, the second floor joists rest on a band attached to studs that go from the foundation to the attic. That allows the cold air in the outer walls to circulate under the second floor floor. Visualize a letter "H" where the cross on the "H" is the second floor joist.
It's still really cold, and radiates through the entire second floor. Any suggestions welcome on how to alleviate the problem of cold floors.
I was thinking of drilling holes through the floor and spraying a can of expanding foam into each joist cavity end, but that seems extreme.
