The Aluprof folding door system is perfect as a connection between the house space and the garden or terrace. It is very often used in winter gardens. It can often be seen in commercial buildings, such as restaurants, where it significantly enlarges the usable space. Folding doors can be made based on the MB-59S, MB-60 or MB-70 systems, thanks to which they can be easily joined with other walls. A very comfortable solution is the possibility to fold the folding wings inside and outside (based on the MB-59S Casement system). Thanks to this, even when there is not enough space inside the house or winter garden to fold the wings, we can use a solution that allows the wings to be folded from the outside. The folding door system is each time constructed from thermally insulated profiles, and the width of the frame and wing depends on the system in which it is constructed.
