The high-speed fold-up door has been designed for intensive use in large outdoor openings, thanks to its great resistance to draughts. Its air tightness means that different working areas can be isolated, allowing for units to be prepared, compartmentalized and climatized for better worker comfort. The reinforcing crossbars on the fabric protect the inside from adverse environmental conditions. Its high resistance to wind and size make it the best solution for outdoor openings. The Nirmal Apex fold-up doors are a great option for industrial doors. The variety of configuration options available means that the door can be customized in line with project requirements.
