Suitable for homes with crawlspaces.

A crawlspace system effectively reduces radon by sealing the crawlspace with a vapor barrier and using active suction to vent gas outside. It can improves indoor air quality, control moisture, and can enhance energy efficiency by reducing humidity and drafts. While installation is more involved, it provides proven protection against radon, making it a valuable investment for homes with crawlspaces.
