Insulting rim joist with uncapped block foundation
I am planning on insulating the rim joist and sill plate for the entire house. I have a concrete block foundation. Some sections are capped with a smaller brick type block. Another section has a wood sill plate and other sections are simply open block at the top of the foundation. I am planning on using spray foam for the insulation to get the rim joist, a few inches of the subfloor and the top of the foundation. What should I do about the section of open block? Should I fill it with spray foam? Use rigid foam to fill each block first? Let it be? Please advise and thank you in advance.
