How to make fly screens for wind out windows 

Fly screens for wind-out windows are a practical addition to your home or camper, keeping pesky insects at bay while allowing fresh air to circulate. Making your own fly screens can be a cost-effective and rewarding DIY project. In this step-by-step guide, we’ll walk you through the process of creating custom fly screens for wind-out windows, ensuring that you can enjoy bug-free ventilation in your space.

Step 1: Gather Your Materials Before you begin crafting your fly screens, it’s essential to gather the necessary materials and tools. Here’s what you’ll need:

  1. Mesh Material: Choose a durable and fine mesh material designed for insect protection. Fiberglass and aluminum mesh are popular choices.
  2. Screen Frame Material: You can use materials like aluminum or PVC (polyvinyl chloride) for the frame.
  3. Spline or Rubber Gasket: This is used to secure the mesh into the frame.
  4. Measuring Tape: For accurate measurements.
  5. Miter Saw or Hacksaw: To cut the frame material to the desired lengths.
  6. Corner Connectors: These are used to join the frame pieces at the corners.
  7. Utility Knife or Scissors: For cutting the mesh.
  8. Spline Roller or Flat-Edged Tool: To help insert the spline or gasket.
  9. Pencil or Marker: For marking measurements.
  10. Safety Gear: Wear gloves and safety glasses for protection.

Step 2: Measure the Window Start by accurately measuring the dimensions of the window where you intend to install the fly screen. Measure both the width and height of the opening, as well as any additional measurements you may need for the frame.

Step 3: Cut the Frame Material Using a miter saw or hacksaw, cut the frame material into pieces according to the measurements you obtained in Step 2. You’ll need four pieces—two for the vertical sides and two for the horizontal sides.

Step 4: Assemble the Frame Assemble the frame using corner connectors to create a rectangular frame that matches the dimensions of your window. Ensure that the corners are square, as this will help the frame fit securely.

Step 5: Prepare the Mesh Material Cut the mesh material to a size slightly larger than the frame. It should overlap the frame by about half an inch on all sides. This extra material will be used to secure the mesh to the frame.

Step 6: Install the Mesh To secure the mesh to the frame, follow these steps:

  1. Lay the frame flat on a clean, flat surface.
  2. Place the mesh material over the frame, ensuring it’s centered.
  3. Starting from one corner, press the spline or rubber gasket into the frame’s channel, securing the mesh in place. Use a spline roller or a flat-edged tool to help insert the spline.
  4. Work your way around the frame, gradually inserting the spline or gasket into the channel on all sides. Be sure to keep the mesh taut as you go.
  5. Trim any excess mesh material with scissors or a utility knife.

Step 7: Trim and Finish Once the mesh is securely in place, trim any remaining spline or gasket material flush with the frame. This will give your fly screen a neat and finished appearance.

Step 8: Install the Fly Screen With your custom fly screen ready, it’s time to install it in your wind-out window. Depending on your window design, there are various installation methods. Some options include:

  1. Magnetic Strips: Attach magnetic strips to the frame of the fly screen and the window frame. They will hold the fly screen in place.
  2. Velcro Strips: Adhere Velcro strips to the fly screen and the window frame to secure it.
  3. Spring Clips: Install spring clips onto the window frame, allowing you to snap the fly screen into place.
  4. Sliding Channels: If your window has channels, you can slide the fly screen into them for a secure fit.

Choose the installation method that best suits your window type and follow the manufacturer’s instructions if applicable.

Step 9: Test and Adjust After installation, test the fly screen to ensure it fits securely and effectively keeps insects out while allowing air to flow freely. Make any necessary adjustments to the installation or the frame to ensure a snug fit.

Step 10: Maintenance To ensure the longevity of your DIY fly screens, periodically inspect them for any damage or signs of wear. Clean the mesh with a gentle detergent and water as needed, and replace any damaged spline or gasket material. Regular maintenance will keep your fly screens in optimal condition.

Conclusion Creating custom fly screens for wind-out windows is a satisfying and practical DIY project that can enhance your living space, whether it’s your home or a camper. With the right materials and careful construction, you can enjoy bug-free ventilation and a comfortable environment. Follow these steps, adapt them to your specific needs, and take pride in your homemade fly screens that provide both protection and convenience.

Step 11: Additional Tips and Considerations

To further enhance your DIY fly screens for wind-out windows, consider the following tips and additional considerations:

  1. Frame Material: Aluminum and PVC are popular choices for frame material due to their durability and resistance to corrosion. Choose a material that suits your needs and matches your window aesthetics.
  2. Mesh Types: While fiberglass and aluminum mesh are commonly used for their durability, consider your specific requirements. For instance, fine stainless steel mesh offers added security and is resistant to corrosion.
  3. Paint or Finish: If you want to match the frame’s color to your window or home decor, you can paint or apply a finish to the frame before installing the mesh.
  4. Custom Shapes: If your windows have unique shapes or curves, adapt the frame and mesh to fit accordingly. Customizing your fly screens to match your window design is entirely possible.
  5. Multiple Screens: If you have several wind-out windows, repeat the process for each one. Having fly screens on all applicable windows ensures consistent insect protection and airflow throughout your space.
  6. Sealing Gaps: Ensure that there are no gaps or openings around the frame when the fly screen is installed. Even small openings can allow insects to enter, defeating the purpose of the screen.
  7. Cleaning and Maintenance: Regularly clean and inspect your fly screens to remove dust, debris, and any potential blockages. Address any damage promptly to extend their lifespan.

Step 12: Enjoy Bug-Free Ventilation

With your custom fly screens securely in place on your wind-out windows, you can now enjoy the benefits of improved ventilation without the nuisance of insects. Whether you’re in a home, camper, or any space with wind-out windows, your DIY fly screens provide comfort, convenience, and peace of mind.


Crafting your own fly screens for wind-out windows is a practical and rewarding DIY project that enhances your living environment. By following these steps and considering additional tips, you can create custom screens that fit perfectly, provide insect protection, and promote efficient airflow. Enjoy the comfort and convenience of bug-free ventilation in your space, whether you’re at home or on the road in your camper.
