Block Ground Moisture Migration Before It Reaches Your Home
A properly installed vapor barrier is foundational to crawlspace moisture control. It limits ground moisture migration and helps stabilize crawlspace humidity when paired with drainage and air-sealing strategy.
What a Vapor Barrier Actually Does
- Reduces vapor diffusion: Limits moisture transfer from soil into crawl air.
- Supports humidity control: Lowers load on dehumidification systems.
- Protects assemblies: Helps preserve insulation and framing by reducing chronic damp exposure.
Installation Quality Factors
- Coverage continuity: Full-floor layout with sealed seams and transitions.
- Perimeter integration: Correct tie-in at walls and penetrations.
- Durability selection: Material strength matched to crawlspace access and service conditions.
- System pairing: Coordinate with drainage and humidity controls for full performance.
Vapor Barrier Is One Part of Full Moisture Control
Vapor barriers work best as part of a complete plan that may include dehumidification, crawlspace repair, and mold prevention strategy.
