PERM-A-BARRIER Aluminum Wall Flashing 6″ x 50′

PERM-A-BARRIER Aluminum Wall Flashing is a self-adhesive, rubberized asphalt/polyethylene detail membrane tailored for air and vapor barrier applications. This product excels in sealing critical areas of the building superstructure to shield them from the damaging effects of the elements. By effectively minimizing air and water vapor flow through the building’s exterior at transition areas, it ensures a continuous air barrier and prevents premature deterioration of the building envelope.

Product Advantages:

• Fully Bonded: Transmits wind loads directly to the substrate, enhancing structural integrity.
• Waterproof and Moisture-Impermeable: Provides robust defense against liquid water and water vapor, ensuring the dryness and longevity of structural elements.
• UV Resistant Aluminum Faced Film: Offers extended UV protection, improved sealant adhesion, dimensional stability, and resistance to tears, punctures, and impacts.
• Cold Applied: Safe application with no flame hazards; self-adhesive overlaps ensure continuity.
• Flexible: Adapts to minor settlement and shrinkage movement, maintaining effectiveness over time.
• Controlled Thickness: Pre-manufactured to consistent specifications to ensure uniform application on site.
• Aggressive, Conformable Adhesive: Self-seals around mechanical fasteners, increasing the reliability of installations.

System Components:

• PERM-A-BARRIER Aluminum Flashing: Main waterproofing component.
• PERM-A-BARRIER WB Primer and BITUTHENE Primer B2 LVC: Primers for enhancing adhesion on various substrates.
• BITUTHENE Mastic Trowel Grade and BITUTHENE Liquid Membrane: Additional sealing options for robust application needs.

Installation: Installation of PERM-A-BARRIER Aluminum Flashing involves careful surface preparation to ensure surfaces are clean, dry, and free of contaminants. The product is compatible with a wide range of temperatures but should be applied when conditions are dry and above 25°F (-4°C). Detailed priming and application steps ensure optimal adhesion and performance.
