Durable Sealing Tape for Vapor & Moisture Protection

3015NP 2-3/8" x 75' Solid Liner Tape is a high-performance self-adhered sealing tape designed for vapor barrier and moisture protection applications in commercial and residential construction. Engineered for strong adhesion and long-lasting durability, this tape helps create a reliable seal around joints, seams, and penetrations in building envelope systems. Its solid liner design allows for clean, efficient installation in a variety of wall and air barrier assemblies.

Key Features:

• Strong Adhesion: Securely bonds to common construction materials
• Solid Liner Design: Easy handling and controlled application
• Moisture Protection: Helps reduce vapor and water infiltration
• Durable Performance: Resistant to weathering and environmental exposure

Benefits:

• Improves building envelope integrity
• Helps reduce moisture intrusion and air leakage
• Supports energy-efficient wall systems
• Easy to install for consistent sealing performance

Applications:

• Vapor barrier system sealing
• Joint and seam protection
• Window and door flashing transitions
• Commercial and residential wall assemblies

3Mâ„¢ Air and Vapour Barrier is an air, moisture, and water impermeable film membrane with an aggressive, high-tack pressure sensitive acrylic adhesive. It reduces air leakage and uncontrolled airflow from the building envelope, prevents moisture ingress and helps improve indoor air quality. It does not require the use of a primer on most construction surfaces.
