In New England, near and below grade insulation needs present challenges because of moisture. Keeping moisture from building components aides in increased building component longevity and occupant comfort, decreased chance of mold and mildew growth, and improved indoor air quality. The basement / crawl space ceiling and rim joist are great places to start. Batt insulation typically installed in floor assemblies are detrimentally affected by moisture and time which weighs these products down and causes them to underperform. Because spray applied foam insulation has the ability to adhere and expand along with a material composition that resists moisture, foam presents a superior option for this problematic area.
