Crawl Space Encapsulation
Crawl space ventilation is a method used to lower radon levels by increasing air circulation under the home. By moving air in and out, radon concentrations are diluted before they can seep into living spaces.

Types of Ventilation
Passive Ventilation
Uses foundation wall vents only (no fans).
Relies on natural airflow and pressure differences.
Very limited effectiveness, especially in calm weather or tightly sealed homes.
Active Ventilation
Uses mechanical fans to actively move air through the crawl space.
Can be more effective than passive methods because it creates consistent airflow.
Often paired with ducting to direct air exchange.

Effectiveness & Considerations
Effectiveness:
Can reduce radon levels, but usually not as effective as sub-membrane depressurization (where a sealed plastic barrier covers the crawl space floor with a fan pulling air from beneath it).
Works better in homes with shallower crawl spaces or when sealing and sub-membrane options are not feasible.
Considerations:
Active ventilation systems require electricity and ongoing operation (fan maintenance, energy use).
May cause increased heating/cooling costs since conditioned air can be drawn from the home.
Should be combined with sealing of major entry points (cracks, utility penetrations) for best results.
In some climates, ventilation may increase humidity and risk of moisture damage if not designed properly.
