Where should EnergyComplete™ Air Infiltration Barrier be used in a crawl space?
If the crawl space is unvented and accessible, it should be treated in the same manner as a basement, sealing all rim joist penetrations and interfaces. If the crawl space is vented or inaccessible, the subfloor will be the air barrier and all penetrations through the subfloor should be sealed from above. In either case, consult the Installation Guide for more details. • Performance 1. How will this system impact air changes per hour in my home? This product will dramatically reduce the number of air changes from typical sources of air infiltration. It is this infiltration of air that wastes energy. To assure maximized energy savings, moisture management and indoor comfort, Owens Corning strongly recommends the use of filtered mechanical ventilation for fresh air makeup, which is supplied at a controlled rate (unlike the uncontrolled infiltration).
