Installation Guide

1. Measure & Cut: Measure the width of your polycarbonate sheet and cut the end closure to the exact length using a fine-tooth saw or sharp utility knife.
2. Clean Sheet Edges: Ensure the polycarbonate sheet edges are clean and free from debris before installation.
3. Apply Breather Tape First: If using polycarbonate sealing tape, apply it to the sheet edge before fitting the end closure.
4. Push-Fit Installation: Slide the U-shaped end closure over the edge of the twin wall sheet, ensuring it fits snugly along the entire length.
5. Secure if Needed: For extra security in high-wind areas, apply a small amount of clear silicone adhesive inside the U-channel before fitting.
6. Check Drip Orientation: Ensure the drip edge is facing downward to direct water away from the roof structure.

Where to Use End Closures

End closures are typically fitted to:

• Top End of Pitched Roofs: The highest point where sheets meet the ridge or wall
• Gutter End of Pitched Roofs: The lower edge where water drains off
• Both Ends of Free-Standing Roofs: Pergolas, carports, and standalone structures
• Vertical Installations: Top and bottom edges of vertical glazing applications

Why End Closures Are Essential

Without proper end closures, twin wall polycarbonate sheets are vulnerable to:

• Dust and dirt accumulation inside flutes, reducing light transmission and appearance
• Insect nesting (particularly wasps and spiders) that’s impossible to remove
• Moisture infiltration leading to algae growth and reduced insulation properties
• Damage to breather tape from UV exposure and weather
• Unprofessional appearance with exposed sheet edges
• Reduced lifespan of your polycarbonate installation
