Now our crawl area is vented with relatively dry air such that things within the crawl house really dry out. (As you heat air, its relative humidity drops.) The more air flow we add to treatment summer time cupping, the more severe the reverse winter cupping. We are slamming the wooden moisture levels from one excessive to the opposite. Other moisture related wooden motion such as swelling and shrinking of doorways occurs in the home as properly. Here in South Carolina, we often have outside air dew level temperatures around 75F.

Duct insulation also stays dry, maintaining the integrity of the insulation. Humidity ranges inside the crawl area and home are more uniform from season to season, creating less movement of hardwood flooring, interior wooden trim and cabinetry. Successful moisture control in some crawl spaces requires complete protection of the soil with a floor cowl and the elimination of ventilation.
