Breaking thermal bridge of dry stacked wall from foundation
I planning to build a house with a basement soon, and looking into dry stacked concrete block walls with exterior foam board insulation. I’m looking into dry stacked wall technique due to cost, durability, thermal mass, and DIY friendliness.
The issue I can’t seem to wrap my head around though is the connection between the foundation/footers and block wall. It seems to me that this would be a huge thermal bridge, and since concrete only has an r-value of <1, I would assume that all the heat capacity of the concrete would quickly be sapped down through the footings. Are my concerns valid? Are there any ways to break this thermal bridge?
