Vapor Barrier vs Full Encapsulation

A plastic sheet on the ground slows moisture from the dirt. Full encapsulation seals the whole crawl space — walls, vents, rim joist — and conditions it.

What Each Does

Vapor barrier: ground-only moisture control. Encapsulation: complete envelope including insulation, vapor barrier, and sealed vents.

Why Encapsulation Wins in Chattanooga

Our humidity is too high for a vapor barrier alone. Without sealed walls and vents, moisture-laden air still gets in.
