How To Measure - FlexScreen
How to measure:
FlexScreen works particularly well for Tilt and Turn and inward opening windows because the screen can remain in place even when the window is closed. You will need to use the pencil test to check if FlexScreen® is suitable for your window.
Additionally please check the outside of your window opener to ensure there are no protrusions, such as trickle vents, that would prevent a successful fitting.
Please note: FlexScreen® is not designed to be fitted and removed on a regular basis.
