A high-speed door is a type of automatic sliding or rolling door that is designed to open and close very quickly. The purpose of this type of door is to maintain the climate of enclosed areas by preventing excessive heat leakage in either direction. Such doors are most widely used in industrial or commercial settings with high traffic levels in and out of a given enclosed area, such as a warehouse. A high-speed door opens and closes rapidly in order to minimize the amount of heat that is able to escape or enter the enclosure, thereby keeping heating and cooling costs as low as possible. They can also be used to ensure that airborne pathogens cannot spread easily between areas, though this is not as common a concern.
