A member of the family has just moved into a property which has double glazed sash windows, made from what looks like uPVC.
There appears to be no way to securly lock the lower sash in a partially raised position so as to provide fresh air.
Is there some mechanism that can be attached that will allow one to raise the lower sash to different levels- depending on how much fresh air is required, and then lock it in the selected position?
alternatively a flexible restrictor like
exact suitability will depend on the window frame and mechanism used.

Owain, just the job! Many thanks for the assistance.
even after watching the video, I still don't get how it works?
Anyone help?

Its just a spring loaded bolt that sits in the top sash above the bottom sash and stops either of them sliding past the other until you put the key in and push the bolt in. It locks automatically when you close the window.
