For example, even though several automatic door types might fit in a specific opening, it is essential to consider how the door should function. Understanding the audience and how it will use the door will help determine what type of door is best. An older population may move slowly through a door, explains Karen H. Maslow, director of marketing, Besam Automated Entrance Systems, Inc., so the swing, slide or folding door needs sufficient safety devices. Because children tend to play around doors, special considerations for sliding doors, such as pocket panels or sidelite protectors, are in order. Another important area is code compliance.
Accessibility is another big issue.
Given the variety of disabilities that qualify under ADA, an automatic door is often a good choice for providing accessibility. That means paying attention to how the door will be activated, how much force will be generated by the door and how the door will be prevented from striking pedestrians. ADA requires that entrances along an accessible route be barrier-free. It is important to remember that some state codes may require a higher bottom rail. Section 4.16.6 discusses minimum maneuvering clearances at doors and slope levels.
