Semi-Rigid PVC is used as “Semi-Rigid Glass”. It is offering clarity, brightness and adaptable ability to be bent or rolled-up.
Semi-rigid PVC strip is most recommended to achieve flexible windows in roll up doors, rapid doors, automatic doors, semi-rigid panels for swing doors or strips doors in warm weather countries.
