: Secure panels to framing members using code-approved fasteners, ensuring they are driven flush with the panel surface. 2. Seam Sealing (ZIP System™ Tape)
: Ideal for sealing irregular shapes, rough openings, and penetrations.
: ZIP System Roof & Wall sheathing is often intended to replace the first layer of underlayment required by building codes, though local regulations may vary.
: Apply ZIP System Tape over all seams and use a J-roller to provide sufficient pressure, which ensures a permanent bond and activates the pressure-sensitive adhesive. 3. Flashing (ZIP System™ Liquid Flash)
: Avoid applying tape if the tape itself is below 20°F (-6.7°C) .
: The system is designed to be permeable, allowing moisture to escape to the exterior rather than acting as a total vapor barrier.
: Use a minimum 32-inch offset (48 inches is preferred) for panel seams to ensure shear strength and avoid vertically stacked joints.
: Install panels with the built-in water-resistive barrier facing outward.
