5. Installation Guide
The Windhager Aluminum Insect Screen Fabric is versatile and can be adapted to various applications, particularly for cellar and roof windows. The installation method will depend on your specific frame or opening.
5.1 Preparation
- Measure the exact dimensions of the opening where the insect screen will be installed.
- Ensure the surface around the opening is clean and dry.
- Gather necessary tools: measuring tape, sharp scissors or utility knife, protective gloves, and appropriate fastening materials (e.g., welting, fastening tape, or clips, sold separately).
5.2 Cutting the Fabric
- Lay the aluminum fabric flat on a clean, stable surface.
- Using your measurements, carefully mark the cutting lines on the fabric.
- Wearing protective gloves, cut the fabric to the required size using sharp scissors or a utility knife. Ensure cuts are straight and precise for a neat fit.
5.3 Fastening the Fabric
Depending on your chosen fastening method:
- Using Welting (Keder): If your frame has a groove, insert the welting around the edges of the cut fabric and press it firmly into the groove of the frame.
- Using Fastening Tape: Apply self-adhesive fastening tape (e.g., hook-and-loop tape) to the frame and the corresponding side to the edges of the fabric. Press firmly to secure.
- Using Fastening Clips: Position the fabric over the opening and secure it with fastening clips around the perimeter, ensuring even tension.
Ensure the fabric is taut and free of wrinkles for optimal performance.

7. Care and Maintenance
To ensure the longevity and effectiveness of your Windhager Aluminum Insect Screen Fabric, follow these simple maintenance guidelines:
- Cleaning: Periodically clean the fabric with a soft brush or a damp cloth to remove dust, pollen, and light debris. For stubborn dirt, a mild soap solution can be used, followed by rinsing with clean water.
- Inspection: Regularly inspect the fabric for any signs of damage, such as tears or holes. Small damages can often be repaired with a patch kit designed for insect screens.

8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
