Reef - Crawl Space Vapor Barriers & Retarders

Ventilated dirt crawl spaces provide a source of moisture that can lead to mold, mildew, fungus and even structural decay. A crawl space can foster environments that lead to severe health issues, environmental moisture problems and increased energy consumption. Therefore, a crawl space needs to be sealed with a crawl space vapor barrier or crawl space vapor retarder to help maintain humidity levels for occupant comfort, reduce heating and cooling costs and minimize other moisture-related problems.
