What Is a Crawl Space Vapor Barrier and Why Do You Need One?

A crawl space vapor barrier is a protective layer designed to block moisture from seeping into your crawl space. Moisture can lead to mold growth, wood rot, and higher energy bills, all of which can cause long-term damage to your property. By installing a vapor barrier, you create a dry, energy-efficient environment that protects your home’s foundation and improves indoor air quality.

At Vapor Barrier Supply, we’ve spent years perfecting our products to ensure they provide top-notch performance in even the toughest conditions.
