Project Overview

Flyscreens are fairly simple to construct. Once you have put one together successfully, you will be able to make enough for the whole house. Build your skills and confidence by completing one window to ensure you are taking the measurements correctly before tackling the rest.


Read the instructions before beginning your project.
Wear an approved dust mask when cutting, planing or sanding timber. 
Always keep tools and materials away from children. 
Safety glasses and ear protection should be worn at all times.


Flyscreen mesh (aluminium or fibreglass)
Flyscreen framing and corner stakes
PVC spline
Safety glasses
Swivel Clips


Measuring Tape
Square and pencil
Mitre box
Spline wheel
Hot water (to soften PVC spline)
Sharp knife

6 Hints and tips
  • Step 1. Measuring

    • Measure the opening width and height.
    • When installing into tracks, measure from the upper inside surface of the top track down to the top outer edge of the bottom track then deduct 3mm for tolerance.
    • Check the vertical measurements on both sides and width measurements top and bottom, as there may be a slight variation in these lengths on older houses.
  • Step 2. Cut the frame

    Cut the frames to length making 45 degree corner cuts using a mitre box and handsaw with a fine toothed blade. In some situations, corner stakes may require a reduction in the length and width of frames to allow for their inclusion so check this detail.
  • Step 3. Make the frame

    Insert the corner stakes and join the frame together. If a little force is required to get it together, use a block of wood between the frame and the hammer to prevent damage.

    Test the frame in the opening. If the opening or flyscreen is out of square, use a little pressure to adjust the flyscreen frame to fit the opening shape.

  • Step 4. Fixing the flyscreen mesh

    • Lay the frame on a flat surface and drape the mesh over it.
    • Cut the mesh on 3 sides to the outside edge of the frame but on the 4th side allow a generous 75-80mm overlap to enable the fabric to be stretched tight.
    • Warm the PVC spline in hot water to make it more pliable so it is easier to manipulate. Use your fingers to work it into position.
    • Start about 90mm from the corner and at the opposite end to the one that has the extra allowances for stretching.
    • Use the spline roller to press the PVC spline into the slot.
    • After completing one end, stretch the mesh tight whilst at the same time inserting the spline into the remaining 3 sides. 
    • Trim the excess with a sharp knife.
    • Attach the catch or swivel clips. Then fit the completed screen into place.
  • Step 5. Finishing

    The completed screen is now ready to be put into place.
  • Step 6. Hints and tips

    Painting should be done before flyscreen is attached to frame.
