Will a Vapor Barrier Reduce Humidity?

Yes. Vapor barriers on their own are an effective way to keep humidity out of your crawl space. Their name implies their function – serving as an impenetrable barrier against water vapor. Keep in mind, using vapor barriers alongside other crawl space solutions guarantees the best possible protection against humidity. FSS can help install a crawl space drain, dehumidifier, and crawl space vent covers that work alongside our 20-mil thick vapor barrier. With these protections in place, your crawl space will be completely protected from humidity.
