What happens to Icynene in the event of a fire?
Icynene does not burn or add fuel to a fire. It will be consumed by the temperature of a fire that has been burning in a house for 15 minutes or so before it gets to the insulation. The Icynene will char, and eventually turn to powder, where fiberglass will char and turn to a lump of glass at the bottom of the cavity under the same fire conditions. The smoke developed by Icynene is rated at “less than 400,” which makes Icynene a Class A insulation. The character of the smoke given off by Icynene is far less hazardous than that given off by the burning of most furniture and carpets.
