All about spray foam
Spray foam safety comes down to installation. Proper installation should result in good product that does not off-gas, poor installations can have very toxic outcomes. Instructions for proper installation of spray foam

I have used spray foam in my house for certain areas where it provides lots of bang for the buck. Educated oversight seems to be required though, since I have also read about some off-gassing horror stories, although thankfully, I have not experienced any myself.
