What is Relative Humidity?

In summer the vents let warm humid air in...and the cool crawl space cools the air and crauses the relative humidity to rise

In summer, vents let warm humid air in. The relative humidity of the cool air in the crawlspace went way up.

Air in a crawlspace is naturally cool because it’s shaded from solar radiation and in direct contact with the earth.

In the summer, when the crawlspace vents and other openings let warm humid air in, the crawlspace cools it.

As the air cools, it cannot hold as much moisture as before, so its relative humidity rises dramatically.

Where Does Moisture Go?

Unfortunately, when the cooling air has more moisture than it can hold the moisture ends up on floor joists, insulation, and other parts of your crawl space. This can have extremely detrimental effects on your crawl space.
