Sliding bi-fold shutters can be equipped with up to six panels per side, i.e. twelve panels per window. When they are folded up, the panels are at right angles to the façade in order to provide additional
protection from the wind and also pro- vide extra privacy. A version with an even number of panels is available as standard, but versions with an odd number are also available.
Two side views show details of the two variants of the bottom runner.
