Homeowners often ask if a vapor barrier is necessary for optimizing attic insulation and protecting their homes from moisture-related damage. The answer, however, isn’t one-size-fits-all.

Cover the floor and foundation walls with a plastic vapor barrier, and use a dehumidifier to remove remaining moisture from the air. All of these steps work together to control moisture levels.
