I would be most grateful if someone could suggest why the inner pane of glass may have cracked in these two patio doors (in separate adjoining rooms). There is no cracking to the external pane.
My inital concern was that there may be movement in the property but the doors slide open quite easily and there is no external evidence of any movement in the property.
A couple of photos attached showing the cracks.
Many thanks for any clues.
