Roll-Up

Standard roll-up doors operate at 8-12 inches per second, while high-speed models can reach 24-60 inches per second. Operation speed depends on door size, curtain material, and counterbalance system. Faster operation reduces wait times but requires more robust construction and maintenance.

Standard roll-up doors can be problematic in freezing temperatures due to curtain stiffness, but insulated models with heating elements perform well in cold storage. High-speed roll-up doors with thermal breaks maintain interior temperatures more effectively than traditional sectional doors.

Roll-up doors need regular curtain inspection, guide cleaning, and bottom seal replacement. The counterbalance system should be checked annually, and curtain lubrication applied as needed. With proper maintenance, roll-up doors can operate reliably for 10-15 years in commercial applications.

Roll-up doors can be designed for wind resistance with reinforced curtains and proper counterbalancing. However, they may not be suitable for extremely high-wind areas where sectional doors with better wind containment are preferred. Wind load ratings are specified during the selection process.

Roll-up doors are generally less expensive to purchase and install than sectional doors of similar size. However, they offer less insulation and may require more frequent maintenance. The cost difference becomes more significant for larger commercial openings where roll-up doors provide substantial savings.
