Their tracks need to be kept clean and free of debris, and if the car gets bent out of shape by an accident, the additional attachment points could make a sliding door more likely to bind up. That slider can't just hang off the side of the car the way a hinged door can when it's open; it actually has to slide somewhere. They're equally impractical when it comes to implementing technological helpers. One-touch auto-open/close sliding doors are borderline no-brainers, but such simple solutions have no place on swinging doors because they might hit something. We've known that swinging doors are not ideal on a family car for decades.

According to the National Safety Council in the United States, around 300,000 door-related injuries occur every year. Most modern exterior walls provide thermal insulation and energy efficiency, which can be indicated by the Energy Star label or the Passive House standards. Premium composite , fiberglass and vinyl doors benefit from the materials they are made from, from a thermal perspective. A remote sensor (e.g. based on infrared or radio waves) can be triggered by a portable remote control, or is installed inside a vehicle. A louvered door has fixed or movable wooden fins which permit open ventilation while preserving privacy and preventing the passage of light to the interior. The oldest door in England can be found in Westminster Abbey and dates from 1050.

The merged corporation, Raytheon Technologies, is among the top five top lobbying spenders in the defense sector and spent almost $11 million on lobbying in 2020.

The hinge of the operating door is next to the adjacent fixed door and the latch is located at the wall opening jamb rather than between the two doors or with the use of an espagnolette bolt. Doors can be hinged so that the axis of rotation is not in the plane of the door to reduce the space required on the side to which the door opens. This requires a mechanism so that the axis of rotation is on the side other than that in which the door opens. This is sometimes the case in trains or airplanes, such as for the door to the toilet, which opens inward.

There are many variations on this basic design, such as the double-leaf door or double door and French windows, which have two adjacent independent panels hinged on each side of the doorway.

The safety sensor prevents the door from colliding with an object by stopping or slowing its motion. A mechanism in modern automatic doors ensures that the door can open in a power failure. A high-speed door is a very fast door some with opening speeds of up to 4 m/s, mainly used in the industrial sector where the speed of a door has an effect on production logistics, temperature and pressure control. High-speed cleanroom doors, usually consisting of a transparent material on a stainless steel frame, are used in pharmaceutical industries to allow passage between work areas while admitting minimal contaminants. The powerful high-speed doors have a smooth surface structure and no protruding edges, allowing minimal particle retention and easy cleaning.

Architectural doors have numerous general and specialized uses. Doors are generally used to separate interior spaces (closets, rooms, etc.) for convenience, privacy, safety, and security reasons. Doors are also used to secure passages into a building from the exterior, for reasons of climate control and safety. Sliding glass doors are common in many houses, particularly as an entrance to the backyard. Such doors are also popular for use for the entrances to commercial structures, although they are not counted as fire exit doors. The door that moves is called the "active leaf", while the door that remains fixed is called the "inactive leaf".
