Is there an option to spray foam when using iICF blocks?
...icf, we need to seal/cover it. What options do i have? Hi Susan, if you mean around the edges of the box and wires I wouldn't be too concerned. With stick-framed houses that can be a big leakage point, but with ICF and the concrete right behind it is more about the insulation value.
Any losses from minor bits of insula...
