Sealed Crawlspaces
Crawl spaces are a constant source of trouble for homes in North Carolina. The traditional approach to crawl spaces has been a vented or open crawl space. This design allows exterior air to freely exchange with the air under your house, where insulation is typically affixed between the floor joists using either a net or metal ties to keep it in place. Open or vented crawl spaces often present a host of issues to homeowners ranging from mold and air quality issues to significant energy loss. The latest research in building sciences indicates that a better approach for North Carolina’s climate is a closed or sealed crawl space.
A closed or sealed crawl space is a crawl space that is completely sealed from the exterior and is insulated. When done correctly, this eliminates humidity, prevents mold and condensation and creates a more energy efficient barrier between the floor of a house and the exterior. Sealed crawl spaces are a great way to immediately improve the comfort level of your living space and reduce your energy consumption. Advanced Energy in their NC field tests have concluded that sealed crawl spaces can reduce a home’s energy bills by as much as 15%-35%.
