Heavy-Duty Tape for Reliable Vapor Sealing
At Vapor Barrier Supply, we know that when it comes to sealing moisture barriers, you can’t afford to cut corners. That’s why we offer premium vapor barrier tape designed for unbeatable adhesion and durability.
Whether you’re sealing crawl spaces, basements, or construction zones, our tapes ensure a long-lasting, waterproof seal that stands up to the toughest conditions. We’ve engineered our products to bond tightly with polyethylene films, preventing even the slightest moisture intrusion.

Let’s face it—humidity and moisture are relentless. If your vapor barrier isn't properly sealed, you’re inviting problems. Our vapor barrier seam tape is specifically designed to create a tight, secure bond that holds strong over time.
Whether you're working on a brand-new installation or patching up an older system, our seam tape gives you the confidence that your vapor barrier will stay intact, no matter what the environment throws at it.
