Fiberglass is a poor insulator that provides a food source for mold and retains moisture. This house was only four years old before the exterior sheeting became compromised with mold and moisture. Closed cell spray foam provides no food source for mold and is a vapor barrier which allows no moisture or air to pass through it. We removed the fiberglass, liberally applied multiple passes of mold killer, and installed 3 inches of closed cell spray foam to achieve an R rating of R21. The homeowners now have a safe, clean, mold free home.
