Installation Notes (Best Practice)

• Surface prep: Apply to clean, dry surfaces free of dust, oils, and debris for maximum adhesion.
• Press firmly: Use hand pressure or a roller to ensure full contact across the tape width.
• Overlap seams: When more than one strip is needed, maintain recommended overlaps to help shed water outward.
• Sequence install: Flash sill first, then jambs, then head to promote proper drainage.

Windows, doors, and wall transitions are critical areas where uncontrolled air and water intrusion can compromise comfort, energy efficiency, and durability. Tyvek® Flashing Tape (6 in x 75 ft) helps strengthen these junctions, delivering balanced coverage that simplifies installation and supports long-term envelope performance.
