• Existing crawl space likely lacked a proper moisture barrier, allowing moisture to permeate the living space above.
• Batt insulation in the crawlspace may have been compromised by moisture, reducing its effectiveness.
Green Attic Insulation recommended a comprehensive crawlspace encapsulation solution for Ellie's home in Naperville, IL. This multi-step approach addressed both moisture control and insulation needs:
✓ Moisture Barrier Installation (1200 sq. ft.): A high-quality, durable moisture barrier was installed on the crawlspace floor to prevent moisture from entering the living space above. This creates a vapor barrier and helps to control humidity levels.
✓ Closed Cell Spray Foam Insulation (720 sq. ft., R-22.5): Three inches of closed-cell spray foam insulation were applied to the crawlspace walls. Closed-cell spray foam has excellent insulating properties and is resistant to moisture, making it ideal for crawl space application.
✓ Batt Insulation Removal (500 sq. ft.): Any existing batt insulation in the crawlspace was removed. Wet or damaged batt insulation loses its effectiveness and can contribute to mold growth.
