Spray Foam...Is it safe?

December 13, 2016

 

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.  

 

Closed cell foam has some excellent characteristics and can provide important air sealing and insulation properties.  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.
