When it comes to protecting your crawl space or foundation, a vapor barrier is not the place to cut corners. At first glance, cheap vapor barriers sold on sites like Amazon or Walmart.com may seem like a smart way to save money. But what you save upfront can cost you in performance, durability, and long-term protection.
Why Cheap Vapor Barriers Aren’t Always a Bargain
To test the difference, our team ordered one of these low-cost options online. What we found confirmed our suspicions:
-
No Specifications: The roll came with no ASTM test data, no performance ratings, and no clear material description. While it claimed to be “virgin resin,” there was no proof or certification.
-
Made Overseas: The product was manufactured in China, which explained the lower price point—but also meant no local quality control, accountability, or support.
-
Durability Concerns: Although the product looked thick, it was noticeably stiffer and less pliable than our American-made vapor barriers. Flexibility matters—a rigid barrier tears more easily during installation, especially around seams and piers.
-
Unknown Composition: Even without an obvious odor, there’s no guarantee that the plastic won’t off-gas or contain fillers, additives, or recycled material that reduce performance over time.
In short, cheap vapor barriers from unknown sources may look like a deal, but they often lack the verified strength and safety you need.
