Question from Jill
We need to use foam in our new construction for a few issues
– to fill in gaps in ICFs (insulated concrete forms)
– to seal around windows
– to seal penetrations
I know that some foams like Great Stuff say things like “no formaldehyde” but there are other components, like isocyanate, which is a sensitizer. I know the odor dissipates over time, but not the toxicity.
I’m seeking suggestions for the least toxic foams. Thanks
