Butterfly doors : Butterfly doors or vertical doors are a type of door sometimes seen on high-performance cars. They are similar to scissor doors. While scissor doors move straight up via hinge points at the bottom of the A-pillar, butterfly doors move up and out via hinges along the A-pillar. This makes for easier entry/exit at the expense of requiring more opening space than needed for scissor doors. The McLaren F1, Alfa Romeo 33 Stradale, Saleen S7, Enzo Ferrari and its non road-going version, the FXX, Toyota Sera/EXY-10, and the Mercedes-Benz SLR McLaren, among others, use butterfly doors. It was also a common feature for Group C and IMSA GTP/Camel Lights prototype racers as they incorporate teardrop tops which allows the driver to get in and out of the car more quickly than conventional and gullwing doors, especially in a cramped pitlane environment such as the pre-1991 Le Mans circuit. Since then, butterfly doors have been an adopted design of closed top sportscar racers, such as the Toyota GT-One, Bentley Speed 8 and more recently, the Peugeot 908 HDi FAP. The Toyota Sera, made between 1990 and 1995, was a limited-release car designed exclusively for the Japanese market which used this design. The Mercedes-Benz SLR McLaren Roadster was one of the few open top cars to use butterfly wing doors. This is made possible by having the doors hinged at the side of A-pillar instead of at top by the roof. The McLaren MP4-12C has a unique system where the butterfly doors do not use a top hinge meaning that the car can use frameless windows which allows for the cars convertible version to retain them.
Sliding glass door : A sliding glass door or patio door, is a type of sliding door in architecture and construction, is a large glass window opening in a structure that provide door access from a room to the outdoors, fresh air, and copious natural light. A sliding glass door is usually considered a single unit consisting of two panel sections, one being fixed and one a 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. The sliding glass door was introduced as a significant element of pre-war International style architecture in Europe and North America. Their precedent is the sliding Shōjiand Fusuma panel door in traditional Japanese architecture. The post-war building boom in modernist and Mid-century modern styles, and on to suburban ranch-style tract houses, multi-unit housing, and hotel-motelchains has made them a standard element in residential and hospitality building construction in many regions and countries.
Applications : 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 Doors also are applied in more specialized cases: • A Blast-proof door is constructed to allow access to a structure as well as to provide protection from the force of explosions. • A garden door is any door that opens to a backyard or garden. This term is often used specifically for French windows, double French doors (with lites instead of panels), in place of a sliding glass door. The term also may refer to what is known as patio doors • A jib door is a concealed door, whose surface reflects the moldings and finishes of the wall. These were used in historic English houses, mainly as servants doors • A pet door (also known as a cat flap or dog door) is an opening in a door to allow pets to enter and exit without the main doors being opened. It may be simply covered by a rubber flap, or it may be an actual door hinged on the top that the pet can push through. Pet doors may be mounted in a sliding glass door as a new (permanent or temporary) panel. Pet doors may be unidirectional, only allowing pets to exit. Additionally, pet doors may be electronic, only allowing animals with a special electronic tag to enter. • A trapdoor is a door that is oriented horizontally in a ceiling or floor, often accessed via a ladder. • A water door or water entrance, such as those used in Venice, Italy, is a door leading from a building built on the water, such as a canal, to the water itself where, for example, one may enter or exit a private boat or water taxi.
Pocket door : A pocket door is a sliding door that disappears, when fully open, into a compartment in the adjacent wall. Pocket doors are used for architectural effect, or when there is no room for the swing of a hinged door. They can travel on rollers suspended from an overhead track or also feature tracks or guides along the floor. Both single- and double-door versions are used, depending on how wide an entry is desired.
