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.

The Griffolyn^® crawl space vapor barrier is made up of several grades of high performance polyethylene material. Griffolyn^® crawl space vapor barriers are available in white polyethylene allowing greater illumination for a cleaner, more attractive crawl space.

This crawl space vapor barrier can be manufactured in sizes to meet specific project requirements to greatly reduce the number of in-field seams and the costs associated with the time and labor required to cut the product to size in the field.
