Does Icynene spray foam support bacterial and/or fungal growth?
Icynene spray foam insulation products do not offer any food value, therefore do not support bacterial or fungal growth. Furthermore, it also does not retain water, making it an unappealing environment for fungal spores. University of Texas has done an experiment on mold growth ability on three different insulation types (Icynene, fiberglass with foil face and fiberglass with vapor barrier). Icynene was found to be the best deterrent for mold growth among the types tested.
