A high-speed roll-up door features a flexible PVC curtain that rolls up and opens at 1.8 m/s, which is significantly faster than a sectional overhead door. The high-speed roll-up door is typically used indoors between departments, while a sectional overhead door is utilized in exterior facades and offers better insulation. The high-speed roll-up door is also more resistant to impacts, as its curtain is not damaged in the same way as a sectional door.
