It seals the crawl space with a heavy vapor barrier on the floor and walls, often adding a dehumidifier, to control moisture, mold, and energy loss.
In humid climates it usually pays back through lower energy bills, better air quality, and protection against rot and pests. A local moisture assessment confirms the fit.
A dry, sealed crawl space is a selling point and prevents costly structural and air-quality issues down the line.
