Meeting building codes on foundation
vents and vapor barriers doesn't prevent excessive humidity
in a crawl space. A crawl space needs to
be ventilated with outdoor air. It is a closed space that is
never cleaned, so there will be molds, spores, chemicals, odors, and
radon that will migrate into your home. These odors & gases need
to be ventilated/diluted with outdoor air.
Besides the necessary ventilation & dilution, the SmartVent®
is a 24 hour watchdog to control humidity in your
crawl space. The patented SmartVent®
measures & compares crawl space and outdoor water vapor in the air.
This is the Key to successful ventilation. measuring humidity is
not effective. The Smartvent® is the only Crawl Space Ventilation
System that does this.
