Mullions
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 and or ...

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 w ...

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, draw ... [...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 windows, sid ...

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 vaul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aluminium
Aluminium (aluminum in American and Canadian English) is a chemical element with the symbol Al and atomic number 13. Aluminium has a density lower than those of other common metals, at approximately one third that of steel. It has a great affinity towards oxygen, and forms a protective layer of oxide on the surface when exposed to air. Aluminium visually resembles silver, both in its color and in its great ability to reflect light. It is soft, non-magnetic and ductile. It has one stable isotope, 27Al; this isotope is very common, making aluminium the twelfth most common element in the Universe. The radioactivity of 26Al is used in radiodating. Chemically, aluminium is a post-transition metal in the boron group; as is common for the group, aluminium forms compounds primarily in the +3 oxidation state. The aluminium cation Al3+ is small and highly charged; as such, it is polarizing, and bonds aluminium forms tend towards covalency. The strong affinity tow ...

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 at the US Embassy, London (1955–60) and by Minoru Yamasaki at the World Trade Center World Trade Centers are sites recognized by the World Trade Centers Association.

Came
A came is a divider bar used between small pieces of glass to make a larger glazing panel. There are two kinds of came: the H-shaped sections that hold two pieces together and the U-shaped sections that are used for the borders. Cames are mostly made of lead, zinc, copper, brass or brass-capped lead.Stevenson, Christine. (2004). ''Creative Stained Glass: Modern Designs & Simple Techniques.'' Lark Books. p. 12. . Of the metal strips, lead is softer and more flexible, making it easier to cut and bend. The harder metals are used to work with slightly curved lines and pieces that require greater structural support. They can also be used as border came, once again for stability and support.Shannon, George and Pat Torlen. (2002). ''The new stained glass: techniques, projects, patterns, designs.'' Sterling Publishing Company, Inc. p. 51. . Purpose Came serves three purposes:Berry, Leigh Ann. (2003). ''Basic Stained Glass Making: All the Skills and Tools You Need to Get Started.'' Stack ...

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, illus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sash Window
A sash window or hung sash window is made of one or more movable panels, or "sashes". The individual sashes are traditionally paned window (architecture), paned windows, but can now contain an individual sheet (or sheets, in the case of double glazing) of glass. History The oldest surviving examples of sash windows were installed in England in the 1670s, for example at Ham House.Louw, HJ, ''Architectural History'', Vol. 26, 1983 (1983), pp. 49–72, 144–15JSTOR The invention of the sash window is sometimes credited, without conclusive evidence, to Robert Hooke. Others see the sash window as a Dutch invention. H.J. Louw believed that the sash window was developed in England, but concluded that it was impossible to determine the exact inventor. The sash window is often found in Georgian architecture, Georgian and Victorian architecture, Victorian houses, and the classic arrangement has three panes across by two up on each of two sash, giving a ''six over six'' panel window, alth ...

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 ...
