  • HEAVY-DUTY VAPOR BARRIER TAPE — Protect your moisture control projects with our 4 inch x 180 foot vapor barrier tape featuring a durable 9 mil polyethylene backing and premium pressure-sensitive acrylic adhesive. Designed to seal seams, overlaps, and repairs on vapor barriers, plastic sheeting, and polyethylene liners, it provides reliable performance for crawl spaces, basements, foundations, and insulation systems.
  • STRONG ACRYLIC ADHESIVE FOR LONG-LASTING BONDS — Engineered with a high-tack acrylic adhesive, this PE seam tape bonds securely to polyethylene film, plastic sheeting, concrete, wood, insulation, and other clean building materials. The aggressive adhesive helps reduce edge lifting while creating durable seams that help resist moisture infiltration over time.
  • IDEAL FOR CRAWL SPACE ENCAPSULATION — Specifically designed for crawl space encapsulation and vapor barrier installation, this crawl space tape seals overlapping plastic sheeting, repairs damaged liners, and reinforces seams around foundation walls, support posts, pipes, and other penetrations. Also suitable for basement moisture control and HVAC duct insulation applications.
  • MOISTURE & TEMPERATURE RESISTANT — Constructed with durable polyethylene film, this moisture barrier tape is designed to perform in humid indoor environments while maintaining flexibility through seasonal temperature changes. The 9 mil backing provides excellent durability for long-term vapor barrier sealing and insulation projects.
  • EASY TO APPLY & PROFESSIONAL RESULTS — The self-adhesive design makes installation fast and simple. For best results, clean and dry the surface, overlap vapor barrier sheeting by at least 6 inches, center the tape over the seam, and apply firm pressure using a roller. The generous 180-foot roll reduces roll changes, making it ideal for large crawl space encapsulation and construction projects.
  • STORAGE & GUARANTEE — Store at normal temperatures , normal humidity , in a well-ventilated area away from direct sunlight.Please feel free to contact us if you have any questions. We are available 24 hours a day.
