Heat loss through rim joist
I recently installed a tube and plate system in a new house. Inch and a half holes were drilled through the joists within an inch to an inch and a half from the rim joist up near the top of the joist, for the loops to cross from one bay to the next. The aluminum plates stop about a foot from the rim joist. Now, it has been brought to my attention that insulation can't be installed between my tubing and the rim joist, and there will be unacceptable heat loss through the rim joist.
I can't argue with that, and now I really wish I had my helper drill the holes a lot further from the rim joist. Am I totally screwed, or can I elongate the holes a little, allow some 2" rigid insulation to be installed on the rim joist, and put some burley pipe insulation on the pipe as it nears the rim joist? There is a code in my state that, if I undertand correctly, requires r-21 between the heated space and the exterior.
Thank you for any engouraging solutions.
