• Strong Adhesion: Bonds securely to a variety of construction surfaces
• Split Liner Design: Allows for easier positioning and controlled application
• Durable Construction: Resistant to weathering and environmental exposure

Benefits:

• Improves building envelope performance and energy efficiency
• Helps protect wall systems from moisture intrusion
• Supports airtight construction practices
• Easy to install for dependable long-term sealing

Applications:

• Air and vapour barrier system sealing
• Joint and seam transitions
• Window and door flashing applications
• 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.
