Get a dependable seal for demanding jobs with Echotape Vinyl Vapor Barrier Tape (3 Pack). Designed for crawl space encapsulation, window sealing, plywood seams, HVAC installations, and insulation projects, this heavy-duty 3" x 180' tape provides a long-lasting, professional-grade bond. Constructed with a tough 7 mil vinyl backing and a high-tack synthetic rubber adhesive, it adheres securely to wood, metal, and polyethylene without curling or requiring heat tools. The 3-inch width allows for faster coverage with fewer overlaps, saving both time and materials. With a low permeability rating of 0.357200 g/sq. m/day (0.023045 g/100 sq. in/day), it offers excellent moisture-blocking performance—helping protect surfaces from water intrusion and maintain structural integrity in high-humidity areas like basements and crawl spaces. UV-resistant and weatherproof, it withstands extreme temperatures and outdoor exposure. When temporary sealing is needed, it can be removed within 7–10 days with minimal residue. Proudly made in the USA, this 3-pack delivers consistent quality, reliable adhesion, and performance for both contractors and DIY users. Pro Tip: Apply to clean, dry surfaces for the best bond. Works on wood, metal, and polyethylene; not recommended for rolled foam insulation or heavily textured surfaces.
