Fascia (architecture)
Fascia () is an architectural term for a vertical frieze or band under a roof edge, or which forms the outer surface of a cornice, visible to an observer. Typically consisting of a wooden board, unplasticized PVC (uPVC), or non-corrosive sheet metal, many of the non-domestic fascias made of stone form an ornately carved or pieced together cornice, in which case the term fascia is rarely used. The word fascia derives from Latin ''fascia'' meaning "band, bandage, ribbon, swathe". The term is also used, although less commonly, for other such band-like surfaces like a wide, flat trim strip around a doorway, different and separate from the wall surface. The horizontal "fascia board" which caps the end of rafters outside a building may be used to hold the rain gutter. The finished surface below the fascia and rafters is called the soffit or eave. In classical architecture, the fascia is the plain, wide band (or bands) that make up the architrave section of the entablature, d ...

Guttae
A gutta (Latin pl. guttae, "drops") is a small water-repelling, cone-shaped projection used near the top of the architrave of the Doric order in classical architecture. At the top of the architrave blocks, a row of six ''guttae'' below the narrow projection of the taenia (fillet) formed an element called a regula. A ''regula'' was aligned under each triglyph of the Doric frieze. In addition, the underside of the projecting geison above the frieze had rectangular protrusions termed ''mutules'' that each had three rows of six ''guttae''. These mutules were aligned above each triglyph and each metope. It is thought that the guttae were a skeuomorphic representation of the pegs used in the construction of the wooden structures that preceded the familiar Greek architecture in stone. However, they have some functionality, as water drips over the edges, away from the edge of the building. Outside the Doric In the strict tradition of classical architecture, a set of guttae alway ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soffit
A soffit is an exterior or interior architectural feature, generally the horizontal, aloft underside of any construction element. Its archetypal form, sometimes incorporating or implying the projection of beams, is the underside of eaves (to connect a retaining wall to projecting edge(s) of the roof). The vertical band at the edge of the roof is called a fascia. Etymology The term ''soffit'' is from it, soffitto, formed as a ceiling; and directly from ''suffictus'' for ''suffixus'', la, suffigere, to fix underneath). Soffits in homes and offices In architecture, soffit is the underside (but not base) of any construction element. Examples include: Under the eaves of a roof In foremost use ''soffit'' is the first definition in the table above. In spatial analysis, it is one of the two necessary planes of any (3-dimensional) optionally built area, eaves, which projects, for such area to be within the building's space. In two-dimensional face analysis it is a discr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eaves
The eaves are the edges of the roof which overhang the face of a wall and, normally, project beyond the side of a building. The eaves form an overhang to throw water clear of the walls and may be highly decorated as part of an architectural style, such as the Chinese dougong bracket systems. Etymology and usage According to the ''Oxford English Dictionary'', ''eaves'' is derived from the Old English (singular), meaning "edge", and consequently forms both the singular and plural of the word. This Old English word is itself of Germanic origin, related to the German dialect ''Obsen'', and also probably to ''over''. The Merriam-Webster dictionary lists the word as ''eave'' but notes that it is "usually used in plural". Function The primary function of the eaves is to keep rain water off the walls and to prevent the ingress of water at the junction where the roof meets the wall. The eaves may also protect a pathway around the building from the rain, prevent erosion of the foot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bargeboard
Bargeboard (probably from Medieval Latin ''bargus'', or ''barcus'', a scaffold, and not from the now obsolete synonym "vergeboard") or rake fascia is a board fastened to each projecting gable of a roof to give it strength and protection, and to conceal the otherwise exposed end grain of the horizontal timbers or purlins of the roof. History Historically, bargeboards are sometimes moulded only or carved, but as a rule the lower edges were cusped and had tracery in the spandrels besides being otherwise elaborated. An example in Britain was one at Ockwells in Berkshire (built 1446–1465), which was moulded and carved as if it were intended for internal work. Modern residential rake fascias are typically made of 2-by dimensional lumber, with trim added for decoration and/or weatherproofing later.

Cymatium
Cymatium, the uppermost molding at the top of the cornice in the classical order, is made of the s-shaped cyma molding (either ''cyma recta'' or ''cyma reversa''), combining a concave cavetto with a convex ovolo. It is characteristic of Ionic columns and can appear as part of the entablature, the epistyle or architrave, which is the lintel or beam that rests on the capitals of columns, and the capital itself. Often the cymatium is decorated with a palmette or egg-and-dart ornament on the surface of the molding. The heights of the parts of the capital are to be so regulated that three of the nine parts and a half, into which it was divided, lie below the level of the astragal on the top of the shaft. The remaining parts are for the cymatium, abacus, and channel. The projection of the cymatium beyond the abacus is not to be greater than the size of the diameter of the eye f the voluteIn the case of a concave-convex profile, a distinction is made between cyma recta and cyma reve ...

Triglyph
Triglyph is an architectural term for the vertically channeled tablets of the Doric frieze in classical architecture, so called because of the angular channels in them. The rectangular recessed spaces between the triglyphs on a Doric frieze are called metopes. The raised spaces between the channels themselves (within a triglyph) are called ''femur'' in Latin or ''meros'' in Greek. In the strict tradition of classical architecture, a set of guttae, the six triangular "pegs" below, always go with a triglyph above (and vice versa), and the pair of features are only found in entablatures of buildings using the Doric order. The absence of the pair effectively converts a building from being in the Doric order to being in the Tuscan order. The triglyph is largely thought to be a tectonic and skeuomorphic representation in stone of the wooden beam ends of the typical primitive hut, as described by Vitruvius and Renaissance writers. The wooden beams were notched in three separate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Doric Order
The Doric order was one of the three orders of ancient Greek and later Roman architecture; the other two canonical orders were the Ionic and the Corinthian. The Doric is most easily recognized by the simple circular capitals at the top of columns. Originating in the western Doric region of Greece, it is the earliest and, in its essence, the simplest of the orders, though still with complex details in the entablature above. The Greek Doric column was fluted or smooth-surfaced, and had no base, dropping straight into the stylobate or platform on which the temple or other building stood. The capital was a simple circular form, with some mouldings, under a square cushion that is very wide in early versions, but later more restrained. Above a plain architrave, the complexity comes in the frieze, where the two features originally unique to the Doric, the triglyph and gutta, are skeuomorphic memories of the beams and retaining pegs of the wooden constructions that preceded ...

Drop (liquid)
A drop or droplet is a small column of liquid, bounded completely or almost completely by free surfaces. A drop may form when liquid accumulates at the lower end of a tube or other surface boundary, producing a hanging drop called a pendant drop. Drops may also be formed by the condensation of a vapor or by atomization of a larger mass of solid. Water vapor will condense into droplets depending on the temperature. The temperature at which droplets form is called the dew point. Surface tension Liquid forms drops because it exhibits surface tension. A simple way to form a drop is to allow liquid to flow slowly from the lower end of a vertical tube of small diameter. The surface tension of the liquid causes the liquid to hang from the tube, forming a pendant. When the drop exceeds a certain size it is no longer stable and detaches itself. The falling liquid is also a drop held together by surface tension. Viscosity and pitch drop experiments Some substances that app ...

Entablature
An entablature (; nativization of Italian , from "in" and "table") is the superstructure of moldings and bands which lies horizontally above columns, resting on their capitals. Entablatures are major elements of classical architecture, and are commonly divided into the architrave (the supporting member immediately above; equivalent to the lintel in post and lintel construction), the frieze (an unmolded strip that may or may not be ornamented), and the cornice (the projecting member below the pediment). The Greek and Roman temples are believed to be based on wooden structures, the design transition from wooden to stone structures being called petrification. Overview The structure of an entablature varies with the orders of architecture. In each order, the proportions of the subdivisions (architrave, frieze, cornice) are defined by the proportions of the column. In Roman and Renaissance interpretations, it is usually approximately a quarter of the height of the column. Va ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frieze
In architecture, the frieze is the wide central section part of an entablature and may be plain in the Ionic or Doric order, or decorated with bas-reliefs. Paterae are also usually used to decorate friezes. Even when neither columns nor pilasters are expressed, on an astylar wall it lies upon the architrave ("main beam") and is capped by the moldings of the cornice. A frieze can be found on many Greek and Roman buildings, the Parthenon Frieze being the most famous, and perhaps the most elaborate. This style is typical for the Persians. In interiors, the frieze of a room is the section of wall above the picture rail and under the crown moldings or cornice. By extension, a frieze is a long stretch of painted, sculpted or even calligraphic decoration in such a position, normally above eye-level. Frieze decorations may depict scenes in a sequence of discrete panels. The material of which the frieze is made of may be plasterwork, carved wood or other decorative medium. ...

Architrave
In classical architecture, an architrave (; from it, architrave "chief beam", also called an epistyle; from Greek ἐπίστυλον ''epistylon'' "door frame") is the lintel or beam that rests on the capitals of columns. The term can also apply to all sides, including the vertical members, of a frame with mouldings around a door or window. The word "architrave" has come to be used to refer more generally to a style of mouldings (or other elements) framing a door, window or other rectangular opening, where the horizontal "head" casing extends across the tops of the vertical side casings where the elements join (forming a butt joint, as opposed to a miter joint). Classical architecture In an entablature in classical architecture, it is the lowest part, below the frieze and cornice. The word is derived from the Greek and Latin words ''arche'' and ''trabs'' combined to mean "main beam". The architrave is different in the different Classical orders. In the Tuscan o ...
