Adjustable Drying Mechanism
The NC Sealed Crawlspace Code requires a mechanical means of moisture control. For crawlspaces with existing supply duct-work a simple louvered vent will suffice as the Code Approved Crawlspace Drying Mechanism. This is far superior to a dehumidifier. In homes with no ducting in the crawlspace it is possible to create a duct-run just for the crawlspace.
