Here is a question that came in to ICF Builders Group:

Where can I find out about toxicity of the ICF blocks? How can you mitigate interior off gassing of the petrochemical styrofoam?

Thank you,

The Canadian Mortgage and Housing Association (equivalent to the NAHB) did
extensive testing on the amount of off-gassing present from rigid EPS foam
insulation, and compared it to paint, drywall, and other construction
materials.

In short, nearly all (upward of 95%) of off-gassing occurs within a few
hours of molding, and by the time the forms are installed in a home, it's
practically undetectable.
