what

A door designed to pivot on hinges or pivots, allowing it to open in either direction, is characterized by its bidirectional movement. These doors are commonly found in commercial settings such as restaurants and retail stores, facilitating easy passage in high-traffic areas. An example includes the familiar doors leading into a restaurant kitchen, allowing staff to move freely in and out. Conversely, a door restricted to opening in only one direction, or sliding open instead of pivoting, represents the alternative. Standard residential doors, which swing inward or outward from a fixed jamb, exemplify this latter category.

The benefit of bidirectional doors lies primarily in their convenience and efficiency in managing pedestrian flow. They minimize obstruction and accommodate users approaching from either side, streamlining movement in busy environments. Historically, these doors have been employed in settings where speed and ease of access are paramount, contributing to operational effectiveness. The alternative type of door, offering controlled access and enhanced security, provides benefits in environments where these factors are more critical than ease of passage. Traditional doors provide a higher degree of weather sealing and are easier to secure.
