Our 12-Mil Woven Vapor Barrier is the same high-quality material used by Crawl Space Ninja franchises when professionally encapsulating homes. Designed for exceptional durability and moisture protection, this reinforced vapor barrier features a woven core for added strength while maintaining a solid, single-sheet construction—eliminating the risk of separation over time.

FAQ: What’s the Difference Between the 12 Mil Woven Vapor Barrier and the Standard 12 Mil Vapor Barrier?

Q: Are both barriers truly 12 mil thick?
A: Yes. Both options are a true 12 mil thickness, measured across the full sheet—not just at the highest point—so you get reliable protection either way.

Q: What’s the benefit of the woven option?
A: The 12 Mil Woven Vapor Barrier is reinforced with a woven polyethylene core, giving it added tear resistance and strength for high-traffic or more demanding crawl space conditions. It’s ideal for jobs where durability is key—like contractor installs or larger projects.

Q: Is the woven barrier still a single sheet?
A: Yes. Even with the reinforcement, the woven version is manufactured as a solid one-piece material. It does not rely on glued layers like some inferior reinforced products. That means no risk of peeling or separation over time.

Q: Does one last longer than the other?
A: Both are long-lasting, but the woven version offers extra toughness—especially helpful in areas where tools, foot traffic, or storage could stress the barrier.

Q: What about odor?
A: Neither product uses adhesives, so neither has the “cat urine” smell that can happen with cheaper laminated or glued vapor barriers.

Q: Which should I use?
A:

• Choose Standard 12 Mil if you want a cost-effective, solid vapor barrier for basic encapsulation jobs.

• Choose 12 Mil Woven for added durability in larger, high-traffic, or professional-grade installations.
