Adjust Double Glazed Window

[scb31]

I have a couple of fairly large (1200 x 520mm) side opening double glazed windows that seem to have dropped on the non-hinge side, leaving a small gap at the top.

How can I adjust them to correct this? There is a concertina type hinge top and bottom of window screwed info frame, with no obvious way of adjustment.

Any help gratefully received.

TIA

you can toe and heal the glass with packers, there was a link posted the other day on a similar thread.

Thanks for the info. I did do a search before posting but obviously not for the right wording!! Toe & healing it is - thanks again.
