Dorma was founded by Wilhelm Dörken and Rudolf Mankel as Dörken & Mankel KG in Ennepetal, Germany, in 1908. [2] The family business was managed by owner Karl-Rudolf Mankel in third generation. As part of succession planning, previous sole Dorma proprietor Karl-Rudolf Mankel transferred the majority of his shareholding to his daughters Christine and Stephanie in March 2009.
In April 2015, Dorma Holding announced a planned merger with Swiss-based Kaba Group. [3] The group went on to become Dormakaba Group.
The company was divided into six divisions: Door Control, Automatics, Glass, Movable Walls, Security Systems & Trade Counters. Dorma’s head office in Ennepetal controlled 69 wholly owned companies in 45 countries. Its major production plants were located in Europe, China, Malaysia, North and South America.
A door is a hinged or otherwise movable barrier that allows ingress (entry) into and egress (exit) from an enclosure. The created opening in the wall is a doorway or portal. A door's essential and primary purpose is to provide security by controlling access to the doorway (portal). Conventionally, it is a panel that fits into the doorway of a building, room, or vehicle. Doors are generally made of a material suited to the door's task. They are commonly attached by hinges, but can move by other means, such as slides or counterbalancing.
A wall is a structure and a surface that defines an area; carries a load; provides security, shelter, or soundproofing; or, is decorative. There are many kinds of walls, including:
A window is an opening in a wall, door, roof, or vehicle that allows the exchange of light and may also allow the passage of sound and sometimes air. Modern windows are usually glazed or covered in some other transparent or translucent material, a sash set in a frame in the opening; the sash and frame are also referred to as a window. Many glazed windows may be opened, to allow ventilation, or closed to exclude inclement weather. Windows may have a latch or similar mechanism to lock the window shut or to hold it open by various amounts.
Physical security describes security measures that are designed to deny unauthorized access to facilities, equipment, and resources and to protect personnel and property from damage or harm. Physical security involves the use of multiple layers of interdependent systems that can include CCTV surveillance, security guards, protective barriers, locks, access control, perimeter intrusion detection, deterrent systems, fire protection, and other systems designed to protect persons and property.
In passive solar building design, windows, walls, and floors are made to collect, store, reflect, and distribute solar energy, in the form of heat in the winter and reject solar heat in the summer. This is called passive solar design because, unlike active solar heating systems, it does not involve the use of mechanical and electrical devices.

A bank vault is a secure space where money, valuables, records, and documents are stored. It is intended to protect their contents from theft, unauthorized use, fire, natural disasters, and other threats, much like a safe. Unlike safes, vaults are an integral part of the building within which they are built, using armored walls and a tightly fashioned door closed with a complex lock.
A sunroof is a movable panel that opens to uncover a window in an automobile roof, allowing light and fresh air to enter the passenger compartment. Sunroofs can be manually operated or motor driven, and are available in many shapes, sizes and styles. While the term "sunroof" is now used generically to describe any moveable panel in the roof, the term "moonroof" was historically used to describe stationary glass panes rigidly mounted in the roof panel over the passenger compartment. A moonroof has a glass panel that is transparent and usually tinted. Previous terms include sunshine roof, sliding head, and sliding roof.
A garage door is a large door to allow egress for a garage that opens either manually or by an electric motor. Garage doors are frequently large enough to accommodate automobiles and other vehicles. The operating mechanism is usually spring-loaded or counterbalanced to offset the door's weight and reduce the human or motor effort required to operate the door. Less commonly, some garage doors slide or swing horizontally. Doors are made of wood, metal, or fiberglass, and may be insulated to prevent heat loss.
In architecture and construction, a sliding glass door is a type of sliding door made predominantly from glass, that is situated in an external wall to provide egress and light. The doors can give access to a backyard or patio while providing a pleasant view, and when not fully covered can be a source of passive daylighting. Like a window, when open it also provides fresh air and copious natural light. It is considered a single unit consisting of two or more panel sections, some or all being mobile to slide open. Another design, a wall-sized glass pocket door has one or more panels movable and sliding into wall pockets, completely disappearing for a 'wide open' indoor-outdoor room experience.
A sliding door is a type of door which opens horizontally by sliding, usually parallel to a wall. Sliding doors can be mounted either on top of a track below or be suspended from a track above. Some types slide into a space in the parallel wall in the direction of travel, rather than the door sliding along the outside of the parallel wall. There are several types of sliding doors, such as pocket doors, sliding glass doors, center-opening doors, and bypass doors. Sliding doors are commonly used as shower doors, glass doors, screen doors, and wardrobe doors, and in vans.
A semi-trailer is a trailer without a front axle. The combination of a semi-trailer and a tractor truck is called a semi-trailer truck.
The term door security or door security gate may refer to any of a range of measures used to strengthen doors against door breaching, ram-raiding and lock picking, and prevent crimes such as burglary and home invasions. Door security is used in commercial and government buildings, as well as in residential settings.

A roller shutter, security shutter, coiling door, roller door or sectional overhead door is a specialized type of door or window shutter consisting of multiple horizontal slats, bars, or web systems interconnected through hinges. The mechanism involves lifting the door to open it and lowering it to close. In the case of larger doors, an automated, motorized system may be employed.
