Folding doors
Folding doors (i.e. accordion type) are ideal for dividing large areas and openings in business spaces, where there are specific requirements for flexible spacing with movable partitions (offices, showrooms, restaurants, entertaining areas, etc). They offer solutions with a large number of sheets, without particular constraints on dimensions and with smooth scrolling, while occupying the minimum space.
