Mullion
A mullion is a vertical element that forms a division between units of a window or screen, or is used decoratively. It is also often used as a division between double doors. When dividing adjacent window units its primary purpose is a rigid support to the glazing of the window. Its secondary purpose is to provide structural support to an arch or lintel above the window opening. Horizontal elements separating the head of a door from a window above are called transoms. History Stone mullions were used in Armenian, Saxon and Islamic architecture prior to the 10th century. They became a common and fashionable architectural feature across Europe in Romanesque architecture, with paired windows divided by a mullion, set beneath a single arch. The same structural form was used for open arcades as well as windows, and is found in galleries and cloisters. In Gothic architecture windows became larger and arrangements of multiple mullions and openings were used, both for structure ...

Curtain Wall (architecture)
A curtain wall is an outer covering of a building in which the outer walls are non-structural, utilized only to keep the weather out and the occupants in. Since the curtain wall is non-structural, it can be made of lightweight materials, such as glass, thereby potentially reducing construction costs. An additional advantage of glass is that natural light can penetrate deeper within the building. The curtain wall façade does not carry any structural load from the building other than its own dead load weight. The wall transfers lateral wind loads that are incident upon it to the main building structure through connections at floors or columns of the building. A curtain wall is designed to resist air and water infiltration, absorb sway induced by wind and seismic forces acting on the building, withstand wind loads, and support its own weight. Curtain walls may be designed as "systems" integrating frame, wall panel, and weatherproofing materials. Steel frames have largely given ...

Gothic Architecture
Gothic architecture (or pointed architecture) is an architectural style that was prevalent in Europe from the late 12th to the 16th century, during the High and Late Middle Ages, surviving into the 17th and 18th centuries in some areas. It evolved from Romanesque architecture and was succeeded by Renaissance architecture. It originated in the Île-de-France and Picardy regions of northern France. The style at the time was sometimes known as ''opus Francigenum'' (lit. French work); the term ''Gothic'' was first applied contemptuously during the later Renaissance, by those ambitious to revive the architecture of classical antiquity. The defining design element of Gothic architecture is the pointed or ogival arch. The use of the pointed arch in turn led to the development of the pointed rib vault and flying buttresses, combined with elaborate tracery and stained glass windows. At the Abbey of Saint-Denis, near Paris, the choir was reconstructed between 1140 and 1144 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Window
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. In addition to this, many modern day windows may have a window screen or mesh, often made of aluminum or fibreglass, to keep bugs out when the window is opened. Types include the eyebrow window, fixed windows, hexagonal windows, single-hung, and double-hung sash windows, horizontal sliding sash windows, casement windows, awning windows, hopper windows, tilt, and slide windows (often door-sized), tilt and turn windows, transom wi ...

Mullion Wall
A mullion wall is a structural system in which the load of the floor slab is taken by prefabricated panels around the perimeter. Visually, the effect is similar to the stone mullioned windows of Perpendicular Gothic or Elizabethan architecture. The technology was devised by George Grenfell Baines and the engineer Felix Samuely in order to cope with material shortages at the Thomas Linacre School, Wigan (1952) and refined at the Shell Offices, Stanlow (1956), the Derby Colleges of Technology and Art (1956–64). and Manchester University Humanities Building (1961–67) Bill White (1987), ''The Spirit Of BDP'', p 49. A similar concept to the mullion wall was adopted by Eero Saarinen Eero Saarinen (, ; August 20, 1910 – September 1, 1961) was a Finnish-American architect and industrial designer noted for his wide-ranging array of designs for buildings and monuments.

Muntin
A muntin (US), muntin bar, glazing bar (UK), or sash bar is a strip of wood or metal separating and holding panes of glass in a window. Muntins can be found in doors, windows, and furniture, typically in Western styles of architecture. Muntins divide a single window sash or casement into a grid system of small panes of glass, called "lights" or "lites". In UK use, a muntin is a vertical member in timber panelling or a door separating two panels. Windows with "true divided lights" make use of thin muntins, typically 1/2" to 7/8" wide in residential windows, positioned between individual panes of glass. In wooden windows, a fillet is cut into the outer edge of the muntin to hold the pane of glass in the opening, and putty or thin strips of wood or metal are then used to hold the glass in place. The inner sides of wooden muntins are typically milled to traditional profiles. In the US, the thickness of window muntins has varied historically, ranging from very slim in 19th century ...

Glass Mullion System
Glass mullion system or glass fin system is a glazing system in which sheets of tempered glass are suspended from special clamps, stabilized by perpendicular stiffeners of tempered glass, and joined by a structural silicone sealant or by metal patch plates. Notable examples I. M. Pei's National Airlines Sundrome at Terminal 6 of JFK Airport was noted for pioneering the use of glass mullions. The airline terminal has since been closed and demolished, after it and the adjacent TWA Flight Center were replaced by a new Terminal 5. Other buildings employing this system include the Rose Center for Earth and Space, Harvard Medical School in Boston, Massachusetts, NASDAQ The Nasdaq Stock Market () (National Association of Securities Dealers Automated Quotations Stock Market) is an American stock exchange based in New York City.

Transom (architectural)
In architecture, a transom is a transverse horizontal structural beam or bar, or a crosspiece separating a door from a window above it. This contrasts with a mullion, a vertical structural member. Transom or transom window is also the customary U.S. word used for a transom light, the window over this crosspiece. In Britain, the transom light is usually referred to as a fanlight, often with a semi-circular shape, especially when the window is segmented like the slats of a folding hand fan. A prominent example of this is at the main entrance of 10 Downing Street, the official residence of the British prime minister. History In early Gothic ecclesiastical work, transoms are found only in belfry unglazed windows or spire lights, where they were deemed necessary to strengthen the mullions in the absence of the iron stay bars, which in glazed windows served a similar purpose. In the later Gothic, and more especially the Perpendicular Period, the introduction of transoms became co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bifora (architecture)
A bifora is a type of window divided vertically in two openings by a small column or a mullion or a pilaster; the openings are topped by arches, round or pointed. Sometimes the bifora is framed by a further arch; the space between the two arches may be decorated with a coat of arms or a small circular opening (oculus). The bifora was used in Byzantine architecture, including Italian buildings such as the Basilica of Sant'Apollinare Nuovo, in Ravenna. Typical of the Romanesque and Gothic periods, in which it became an ornamental motif for windows and belfries, the bifora was also often used during the Renaissance period. In Baroque architecture and Neoclassical architecture the bifora was largely forgotten, or replaced by elements like the three openings of the Venetian window. It was also copied in the Moorish architecture in Spain, where it is called (from Arabic ).: "from Arabic ''ash-shammīs'' the ajimez" It returned in vogue in the nineteenth century in the period of ec ...

Elizabethan Architecture
Elizabethan architecture refers to buildings of a certain style constructed during the reign of Queen Elizabeth I of England and Ireland from 1558–1603. Historically, the era sits between the long era of the dominant architectural style of religious buildings by the Catholic Church, which ended abruptly at the Dissolution of the Monasteries from c.1536, and the advent of a court culture of pan-European artistic ambition under James I (1603–25). Stylistically, Elizabethan architecture is notably pluralistic. It came at the end of insular traditions in design and construction called the Perpendicular style in the church building, the fenestration, vaulting techniques, and open truss designs of which often affected the detail of larger domestic buildings. However, English design had become open to the influence of early printed architectural texts (namely Vitruvius and Alberti) imported to England by members of the church as early as the 1480s. Into the 16th century, ill ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gothic Cathedrals And Churches
Gothic cathedrals and churches are religious buildings created in Europe between the mid-12th century and the beginning of the 16th century. The cathedrals are notable particularly for their great height and their extensive use of stained glass to fill the interiors with light. They were the tallest and largest buildings of their time and the most prominent examples of Gothic architecture. The appearance of the Gothic cathedral was not only a revolution in architecture; it also introduced new forms in decoration, sculpture, and art. Cathedrals were by definition churches where a bishop presided. Abbeys were the churches attached to monasteries. Many smaller parish churches were also built in the Gothic style. The appearance of the great cathedrals in the 12th century was a response to the dramatic increase of population and wealth in some parts of Europe and the need for larger and more imposing buildings. Technical advances, such as innovative uses of the pointed arch, rib vault ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sundrome
The Sundrome, later TWA Domestic Terminal and Terminal 6, was one of several terminals at John F. Kennedy International Airport. It was designed by I. M. Pei & Partners (now Pei Cobb Freed & Partners). Opened in 1969, it was initially used by National Airlines. It had been occupied at various times by Trans World Airlines (domestic flights), Pan Am, United Airlines (SFO and LAX transcontinental flights), ATA Airlines, Pan American Airways (1996–1998), Carnival Airlines, Vanguard Airlines, and America West Airlines. Most recently, from 1998 to 2008, Terminal 6 was the home of JetBlue. It became vacant on October 22, 2008, when JetBlue moved to Terminal 5, and finally demolished in 2011. Design I.M. Pei, in his design of the Sundrome, used all-glass mullions, unprecedented at the time. History Prior to the construction of the Sundrome, National Airlines used a corrugated metal quonset hut as a terminal located between the eventual location of the Sundrome and Terminal 7 fro ...
