Is there an option to spray foam when using icf blocks?
For a new build, we are considering ICF blocks for the foundation walls. I prefer not to use spray foam. I am aware where the electricial or plumber would cut into the 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 insulation would be minimal, particularly if the cuts are done fairly accurately. If you did not want to use spray foam then any bit of insulation you can jam in an cracks would be a find substitute.
