The rim joist of a home is rarely insulated and never sealed during construction. These joints and gaps between the framing allow for a lot of outside air to enter the home. This means that whatever temperature the outdoor air currently is, the same temperature air is being leaked into the home. This could make for very cold floors in the winter and hot, humid conditions for the crawl space in the summer.
The rim joist counts for almost 30% of the air that enters the typical crawl space. It's important during crawl space encapsulation that the rim joist be properly air sealed. Prevent the excess moisture from entering your home, make your floor warmer and protect your home from the damaging effects of a vented crawl space with proper rim joist air sealing.

When the insulation in vented crawlspaces become wet due to moisture many homeowners notice odd & musty smells in the home. With proper crawlspace encapsulation this insulation is no longer needed. By removing the insulation homeowners increase the comfort in their homes and reduce crawlspace odors.
