In addition to energy consumption, air infiltration and exfiltration within a home contributes to almost 99% of moisture migration.

Critical Requirements for Mold Growth: Available mold spores
Available food for mold spores Appropriate temperatures Considerable moisture

Restricting air movement stops moisture accumulation so that the possibility of mold growth is less likely. Combined with a properly sized HVAC system, spray foam insulation helps control the indoor humidity levels to minimize moisture and condensation. Reducing moisture and controlling humidity can also add years to the life expectancy of a home, plus contribute to a healthier indoor environment.
