Diversified Air Systems supplies roll-up doors for various industrial and commercial needs, including climate control, increased privacy and security, contaminant control, and reduction of noise from adjacent areas. Vinyl doors are available in various colors, and with clear windows when needed for visibility or light. Doors may be manual roll-up, spring-assisted roll-up, or motorized (with wireless controls available). Mesh roll-up doors allow ventilation while keeping out pests such as flies, mosquitoes, bees, wasps, or birds. Bug-blocking mesh also provides a 65% shade factor, keeping non-air-conditioned plant spaces cooler.
