Window Motion
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, ...

Hole
A hole is an opening in or through a particular medium, usually a solid body. Holes occur through natural and artificial processes, and may be useful for various purposes, or may represent a problem needing to be addressed in many fields of engineering. Depending on the material and the placement, a hole may be an indentation in a surface (such as a hole in the ground), or may pass completely through that surface (such as a hole created by a hole puncher in a piece of paper). Types Holes can occur for a number of reasons, including natural processes and intentional actions by humans or animals. Holes in the ground that are made intentionally, such as holes made while searching for food, for replanting trees, or postholes made for securing an object, are usually made through the process of digging. Unintentional holes in an object are often a sign of damage. Potholes and sinkholes can damage human settlements. Holes can occur in a wide variety of materials, and at a wide rang ...

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 ...

Oriel Window
An oriel window is a form of bay window which protrudes from the main wall of a building but does not reach to the ground. Supported by corbels, bracket (architecture), brackets, or similar cantilevers, an oriel window is most commonly found projecting from an upper floor but is also sometimes used on the ground floor. Oriel windows are seen in Arab architecture in the form of mashrabiya and in Turkish are known as ''şahnişin'' or ''cumba''. In Islamic culture, these windows and balconies project from the street-front of a house, providing an area in which women could peer out and see the activities below while remaining invisible. Origins According to the ''Oxford English Dictionary'', the term ''oriel'' is derived from Anglo-Norman language, Anglo-Norman ' and Late Latin ', both meaning "gallery" or "porch", perhaps from Classical Latin ' ("curtain"). * Oriel College, Oxford, took its name from a balcony or oriel window forming a feature of a building which occupied the ...

Bay Window
A bay window is a window space projecting outward from the main walls of a building and forming a bay in a room. Types Bay window is a generic term for all protruding window constructions, regardless of whether they are curved or angular, or run over one or multiple storey A storey (British English) or story (American English) is any level part of a building with a floor that could be used by people (for living, work, storage, recreation, etc.). Plurals for the word are ''storeys'' (UK) and ''stories'' (US). T ...s. In plan, the most frequently used shapes are isosceles trapezoid (which may be referred to as a ''canted (architecture), canted bay window'') and rectangle. But other polygonal shapes with more than two corners are also common as are curved shapes. If a bay window is curved it may alternatively be called ''bow window.'' Bay windows in a triangular shape with just one corner exist but are relatively rare. A bay window supported by a corbel, Bracket (archite ...

Roof Lantern
A roof lantern is a daylighting architectural element. Architectural lanterns are part of a larger roof and provide natural light into the space or room below. In contemporary use it is an architectural skylight structure. A lantern roof will generally mean just the roof of a lantern structure in the West, but has a special meaning in Indian architecture (mostly Buddhist, and stretching into Central Asia and eastern China), where it means a dome-like roof raised by sets of four straight beams placed above each other, "arranged in diminishing squares", and rotated with each set. Normally such a "lantern" is enclosed and provides no light at all. The term ''roof top lantern'' is sometimes used to describe the lamps on roofs of taxis in Japan, designed to reflect the cultural heritage of Japanese paper lanterns. History The glazed lantern was developed during the Middle Ages. Roof lanterns of masonry and glass were used in Renaissance architecture, such as in principal cathedr ...

Roof Window
A roof window is an outward opening window that is incorporated as part of the design of a roof. Often confused with a skylight, a roof window differs in a few basic ways. A roof window is often a good option when there is a desire to allow both light and fresh air into the space. A roof window is also different from a tubular skylight, in that the light is not directed through any type of channel or tube in order to provide lighting for the interior of a building. This type of light tube design is often employed with buildings where the installation of a skylight or roof window is not practical. While a roof window is normally included in the original construction of the building, it is possible to add the design feature to an existing structure. As long as the framework and the slope of the roof allow for the inclusion of this type of window, it can be installed with relative ease. Many manufacturers offer prefabricated window inserts of this type that can be installed by a pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Skylights
A skylight (sometimes called a rooflight) is a light-permitting structure or window, usually made of transparent or translucent glass, that forms all or part of the roof space of a building for daylighting and ventilation purposes. History Open skylights were used in Ancient Roman architecture, such as the oculus of the Pantheon. Glazed 'closed' skylights have been in use since the Industrial Revolution made advances in glass production manufacturing. Mass production units since the mid-20th century have brought skylights to many uses and contexts. Energy conservation has brought new motivation, design innovation, transmission options, and efficiency rating systems for skylights. Prior to the Industrial Revolution, it was Spain and France that probably had the leading technology in architectural glass. One of the earliest forms of glass skylight can be seen at the Burgos Cathedral in the Chapel of the Constable. Other early form of glass skylight can be seen at the Palace o ...

Lancet Window
A lancet window is a tall, narrow window with a pointed arch at its top. It acquired the "lancet" name from its resemblance to a lance. Instances of this architectural element are typical of Gothic church edifices of the earliest period. Lancet windows may occur singly, or paired under a single moulding, or grouped in an odd number with the tallest window at the centre. The lancet window first appeared in the early French Gothic period (c. 1140–1200), and later in the English period of Gothic architecture (1200–1275). So common was the lancet window feature that this era is sometimes known as the "Lancet Period". Retrieved 24 October 2006 The term ''lancet window'' is properly applied to windows of austere form, without |
Clerestory
In architecture, a clerestory ( ; , also clearstory, clearstorey, or overstorey) is a high section of wall that contains windows above eye level. Its purpose is to admit light, fresh air, or both. Historically, ''clerestory'' denoted an upper level of a Roman basilica or of the nave of a Romanesque or Gothic church, the walls of which rise above the rooflines of the lower aisles and are pierced with windows. Similar structures have been used in transportation vehicles to provide additional lighting, ventilation, or headroom. History Ancient world The technology of the clerestory appears to originate in the temples of ancient Egypt. The term "clerestory" is applicable to Egyptian temples, where the lighting of the hall of columns was obtained over the stone roofs of the adjoining aisles, through gaps left in the vertical slabs of stone. Clerestory appeared in Egypt at least as early as the Amarna period. In the Minoan palaces of Crete such as Knossos, by contrast, lightwel ...

Louver
A louver (American English) or louvre (British English British English (BrE, en-GB, or BE) is, according to Lexico, Oxford Dictionaries, "English language, English as used in Great Britain, as distinct from that used elsewhere". More narrowly, it can refer specifically to the English language in ...; American and British English spelling differences#-re, -er, see spelling differences) is a window blind or window shutter, shutter with horizontal wikt:slat, slats that are angled to admit light and air, but to keep out rain and direct sunshine. The angle of the slats may be adjustable, usually in blinds and windows, or fixed. History Louvers originated in the Middle Ages as lantern-like constructions in wood that were fitted on top of roof holes in large kitchens to allow ventilation while keeping out rain and snow. They were originally rather crude constructions consisting merely of a barrel. Later they evolved into more elaborate designs made of pottery, taking th ...

Casement Window
A casement window is a window that is attached to its frame by one or more hinges at the side. They are used singly or in pairs within a common frame, in which case they are hinged on the outside. Casement windows are often held open using a casement stay. Windows hinged at the top are referred to as awning windows, and ones hinged at the bottom are called hoppers. Overview Throughout Britain and Ireland, casement windows were common before the sash window was introduced. They were usually metal with leaded glass, which refers to glass panes held in place with strips of lead called cames (leaded glass should not be confused with lead glass, which refers to the manufacture of the glass itself). These casement windows usually were hinged on the side, and opened inward. By the start of the Victorian era, opening casements and frames were constructed from timber in their entirety. The windows were covered by functional exterior shutters, which opened outward. Variants of casement ... [...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 ...
