This seems a good move; owing to there being a little difference which way they are fitted it looks as though the pivot should be central because it would make them easier to open, a point I think needs improvement. I much prefer this type of ventilator to louvres because they need not be open unless high speed and weather conditions demand. Our old shutters are quite out-of-date schemed about 23 years ago.
