How do you fit a window filter into an insect screen frame?

If your home has a hinged, fixed or sliding insect screen, you can switch to window filter without changing the frame, simply by removing the mesh. The filter sits in the frame channel with standard insect screen spline.

Suitable frames

  • Fixed (removable) insect screens: The easiest to do.
  • Hinged insect screen doors and windows: The most practical solution for a balcony door.
  • Sliding insect screens: Make sure it moves freely in the track.
  • Pleated and roller insect screens: Ask us first because of the folding or rolling mechanism.

What you need

  • Window filter by the roll
  • Insect screen spline (the old one can often be reused)
  • Spline roller or a flat-head screwdriver
  • Utility knife and scissors

Step by step

  1. Take the frame down and remove the old mesh

Fitting window filter into an insect screen frame with spline
A window filter is slightly thicker than ordinary mesh. Some frames with very narrow channels may need a spline one size thinner.

For screen makers

A window filter is a premium option you can offer customers alongside standard mesh. Homes with dust and pollen complaints, babies or family members with allergies ask for it specifically. For bulk rolls and wholesale prices, see wholesale page.

Frequently asked questions

Which side should face out?

The dark side of the filter should face out. That way the filter works best and it is hard to see in from outside.

Can it be fitted to a pleated or roller insect screen?

Because pleated and roller screens work with folding or rolling mechanisms, the filter may not suit every system. If you have this type of screen, ask us with a photo of your system.
