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. [1] 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 Greek revival buildings to thick in 17th and early 18th century buildings.
Until the middle of the 19th century, it was economically advantageous to use smaller panes of glass, which were much more affordable to produce, and fabricate them into a grid to make large windows and doors. [2] The division of a window or glazed door into smaller panes was considered more architecturally attractive than large panes. In the UK and other countries, muntins (often called 'glazing bars' in England and 'astragals' in Scotland) were removed from the windows of thousands of older buildings during the nineteenth century in favor of large panes of plate glass. Restoration of these buildings in the following century often included reinstatement of the glazing bars, which are now seen as essential architectural elements of period buildings.
The term 'muntin' is often confused with 'mullion' (elements that separate complete window units), and 'astragal' (which closes the gap between two leaves of a double door). Many companies use the term 'grille' when referring to a decorative element of wood or other material placed over a single pane of glass to resemble muntins separating multiple panes of glass. In the UK, the term 'grille' tends to be used only when there are bars sandwiched between panes of insulated glass.
Double- or triple-layer insulated glass can be used in place of ordinary single panes in a window divided by muntins, though this reduces the effectiveness of the insulation. Other insulating glass arrangements include insertion of a decorative grid of simulated metal, wooden, or plastic muntins sandwiched between two large panels of glass, sometimes adding another grid of simulated wood muntins facing the interior to produce a more convincing divided light appearance.
In furniture, a muntin is the central vertical member of the framework of a piece of furniture, the outside members being called stiles. [3]
A door is a hinged or otherwise movable barrier that allows ingress (entry) into and egress (exit) from an enclosure. The created opening in the wall is a doorway or portal. A door's essential and primary purpose is to provide security by controlling access to the doorway (portal). Conventionally, it is a panel that fits into the doorway of a building, room, or vehicle. Doors are generally made of a material suited to the door's task. They are commonly attached by hinges, but can move by other means, such as slides or counterbalancing.
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.
A curtain wall is an exterior covering of a building in which the outer walls are non-structural, instead serving to protect the interior of the building from the elements. Because the curtain wall façade carries no structural load beyond its own dead load weight, it can be made of lightweight materials. The wall transfers lateral wind loads upon it to the main building structure through connections at floors or columns of the building.
Tracery is an architectural device by which windows are divided into sections of various proportions by stone bars or ribs of moulding. Most commonly, it refers to the stonework elements that support the glass in a window. The purpose of the device is practical as well as decorative, because the increasingly large windows of Gothic buildings needed maximum support against the wind. The term probably derives from the tracing floors on which the complex patterns of windows were laid out in late Gothic architecture. Tracery can be found on the exterior of buildings as well as the interior.
Moulding, or molding, also coving, is a strip of material with various profiles used to cover transitions between surfaces or for decoration. It is traditionally made from solid milled wood or plaster, but may be of plastic or reformed wood. In classical architecture and sculpture, the moulding is often carved in marble or other stones. In historic architecture, and some expensive modern buildings, it may be formed in place with plaster.
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.
A came is a divider bar used between small pieces of glass to make a larger glazing panel.
An astragal is a moulding profile composed of a half-round surface surrounded by two flat planes (fillets). An astragal is sometimes referred to as a miniature torus. It can be an architectural element used at the top or base of a column, but is also employed as a framing device on furniture and woodwork.
A glazier is a tradesperson responsible for cutting, installing, and removing glass. They also refer to blueprints to figure out the size, shape, and location of the glass in the building. They may have to consider the type and size of scaffolding they need to stand on to fit and install the glass. Glaziers may work with glass in various surfaces and settings, such as cutting and installing windows, doors, shower doors, skylights, storefronts, display cases, mirrors, facades, interior walls, ceilings, and tabletops.

Storm windows are windows that are mounted outside or inside of the main glass windows of a house. Storm windows exist in North America, but are uncommon in continental Europe, where double, triple or quadruple glazing is prevalent. Storm windows can be made of glass, rigid plastic panels, or flexible plastic sheets; and may be permanently or temporarily mounted. They function similarly to insulated glazing. The term may also refer to a small openable flap found in the side window on light aircraft.
A sash window or hung sash window is made of one or more movable panels, or "sashes". The individual sashes are traditionally paned windows, but can now contain an individual sheet of glass.
Leadlights, leaded lights or leaded windows are decorative windows made of small sections of glass supported in lead cames. The technique of creating windows using glass and lead came to be known as came glasswork. The term 'leadlight' could be used to describe any window in which the glass is supported by lead, but traditionally, a distinction is made between stained glass windows and leadlights; the former is associated with the ornate coloured-glass windows of churches and similar buildings, while the latter is associated with the windows of vernacular architecture and defined by its simplicity.
Albany City Hall is the seat of government of the city of Albany, New York, United States. It houses the office of the mayor, the Common Council chamber, the city and traffic courts, as well as other city services. The present building was designed by Henry Hobson Richardson in the Romanesque style and opened in 1883 at 24 Eagle Street, between Corning Place and Pine Street. It is a rectangular three-and-a-half-story building with a 202-foot-tall (62 m) tower at its southwest corner. The tower contains one of the few municipal carillons in the country, dedicated in 1927, with 49 bells.
The former Philip Livingston Magnet Academy is located along Northern Boulevard in the West Hill neighborhood of Albany, New York, United States. It is a large brick building predominantly in the Colonial Revival architectural style, with some Art Deco touches inside, erected during the 1930s. Additions were made in the 1960s. In 2014 it was listed on the National Register of Historic Places as the Philip Livingston Junior High School, the only purpose-built public school building in the city so recognized.
Window insulation reduces heat transfer from one side of a window to the other. The U-value is used to refer to the amount of heat that can pass through a window, called thermal transmittance, with a lower score being better. The U-factor of a window can often be found on the rating label of the window.
Glazing, which derives from the Middle English for 'glass', is a part of a wall or window, made of glass. Glazing also describes the work done by a professional "glazier". Glazing is also less commonly used to describe the insertion of ophthalmic lenses into an eyeglass frame.
Insulating glass (IG) consists of two or more glass window panes separated by a space to reduce heat transfer across a part of the building envelope. A window with insulating glass is commonly known as double glazing or a double-paned window, triple glazing or a triple-paned window, or quadruple glazing or a quadruple-paned window, depending upon how many panes of glass are used in its construction.
The King and Queen is a pub in the seaside resort of Brighton, part of the city of Brighton and Hove. The present building, a "striking" architectural "pantomime" by the prolific local firm Clayton & Black, dates from the 1930s, but a pub of this name has stood on the site since 1860—making it one of the first developments beyond the boundaries of the ancient village. This 18th-century pub was, in turn, converted from a former farmhouse. Built using materials characteristic of 16th-century Vernacular architecture, the pub is in the Mock Tudor style and has a wide range of extravagant decorative features inside and outside—contrasting with the simple design of the neighbouring offices at 20–22 Marlborough Place, designed a year later. English Heritage has listed the pub at Grade II for its architectural and historical importance.
In architecture, a paned window is a window that is divided into panes of glass, usually rectangular pieces of glass that are joined to create the glazed element of the window. Window panes are often separated from other panes by lead strips, or glazing bars, moulded wooden strips known as muntins in the US.
