Full-Coverage Air & Vapour Protection System

3015NP AB WT 36" x 75' Air & Vapour Barrier Membrane is a high-performance self-adhered membrane designed to provide advanced air sealing and moisture protection for commercial and residential building envelope systems. With its extra-wide 36-inch format, this membrane delivers efficient large-area coverage for wall assemblies, transitions, and flashing applications while helping create airtight, energy-efficient structures.

Key Features:

• Air & Vapour Barrier Performance: Helps reduce air leakage and moisture infiltration
• 36" Wide Coverage: Ideal for large-scale wall and transition applications
• Self-Adhered Installation: Provides strong adhesion to common construction substrates
• Durable Construction: Resistant to weathering and environmental exposure

Benefits:

• Improves building envelope efficiency and thermal performance
• Helps protect wall systems from moisture penetration
• Reduces installation time with wide-format coverage
• Provides long-lasting, reliable sealing performance

Applications:

• Air and vapour barrier wall systems
• Exterior wall sheathing protection
• Window and door transition detailing
• Commercial and residential construction projects

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.
