The accordion hanging system, a mechanism that allows the PVC strip curtain to be gathered to the right, left, or both sides when needed, can be applied where physical conditions are suitable, such as the door being at least 30 cm deep, or where this condition is met with additional construction.

This system provides ease of passage thanks to its fully collapsible design; however, the total door width will narrow slightly due to the strips gathered to the side. Since it reduces passage between the strips, this mechanism allows the product to be used for a longer period. To ensure the closure and insulation that is the primary purpose of the PVC strip curtain, both sliding doors and accordion doors must be closed again after work is completed.
