A double glazed unit (1) is provided with a pleated blind member (3) in the space between the two panels (2, 2') of the unit. One end of the blind member (3) is provided with a magnet (7) and a moveable magnet (8) is provided on an exterior face of a panel (2) of the unit (1) adjacent the magnet (7) on the blind. Moving the magnet (8), by attracting the magnet (7), draws the blind member (3) with it and either folds or unfolds the pleats (6) thus opening or closing the blind member (3). |
