Is there an odor? If so, should I be concerned?
There are no blowing agents such as CFC’s (chlorofluorocarbons) or HCFC’s (Hydrochlorofluorocarbons) in Icynene’s light density products. Spray foam insulation is produced by mixing 2 components at a high temperature, which causes the foam to atomize
during installation. This process creates an odor and requires venting. As soon as the foam “cures” (or sets), which occurs within seconds, it no longer produces the odor. It usually takes about 24 hours for the odor to completely dissipate.
