Paned Window Architecture and Styles

Paned window architecture and styles offer a wide range of options for homeowners looking to add a touch of elegance to their homes.

In traditional Victorian homes, paned windows were often arranged in a symmetrical pattern, with multiple panes separated by muntins to create a decorative effect.

The use of paned windows in colonial-style homes dates back to the 17th century, when they were a common feature of American architecture.

The history of paned windows dates back to the 19th century, specifically in industrial settings like factories. Prior to the 1850s, windows in masonry-walled factory buildings had simple rectangular openings with flat jack arches or stone lintels.

In the 1850s, the segmental arch window head became a standard feature, reducing cost and responding to high-style design. The segmental arch window head remained the standard for nearly all fenestration openings in factories of masonry-wall construction until the early 20th century.

The wooden window unit used in these industrial buildings was little different from those used in lintel-headed windows. The head of the upper sash usually remained flat, while the head of the frame was fabricated on a curve only along the underside of the masonry arch.

The twelve-over twelve, double-hung configuration remained standard until the end of the 19th century. Then, the gradual increase in the size of factory windows began to exceed the structural capabilities of existing window technology, and new configurations and operating types were introduced.

The relatively small pane within a multi-pane sash remained a common feature of factory windows, even after the introduction of the steel factory window early in the 20th century.

Paned windows have a long history, dating back to the 17th century. They were a common feature in many European buildings, particularly in England and France.

The design of paned windows involves dividing a single window into multiple smaller panes of glass, typically held together by a frame. This design allows for greater flexibility in terms of the size and shape of the window.

The construction of paned windows often involves using a combination of wood and glass materials. The frame is typically made of wood, while the panes of glass are held in place by glazing bars.

In the 1820s, interior shutters were a common feature in homes, helping control sunlight and regulate temperatures.

They also protected carpets, upholstery, and furniture from fading and guaranteed privacy for residents, who found the view distracting during dinner hours.

Interior shutters were often paneled or louvered, with some featuring a combination of both.

The Kirk Boott House in Lowell, Massachusetts, showcases an unusual type of interior shutter from 1823, where the outermost shutters on both sides of the window are continuous and extend the full height of the window.

These full-length shutters are hinged to two stacked shutters, allowing for four sections to be closed against the sash when needed.

When folded against the wall for storage, the full-length shutter section becomes part of the window room paneling.

The stacked sections provide greater flexibility in controlling light and privacy.

Grilles Between Glass is a cost-effective alternative to SDL that simplifies maintenance for homeowners. By housing the grilles within the glass, you can easily clean the outdoor-facing pane and the interior-facing pane without obstructions.

The design of GBG grilles between two panes of glass makes it easy to clean, eliminating the need to navigate around obstructions. This is a huge advantage for homeowners who value convenience.

GBG is often compared to SDL in terms of appearance, but the key difference lies in the placement of the grilles. In GBG, the grilles are placed between the two panes, while in SDL, they are placed on both sides of a single pane.

Here are the key features of Grilles Between Glass:

Muntins have been a crucial element in window construction for centuries, dating back to the 17th century when glass manufacturing techniques could only produce small panes of glass.

In traditional window construction, muntins were made of wood and were essential in creating larger windows by piecing together smaller panes. Modern muntins are often decorative rather than structural, but they can still enhance the architectural style of a home.

There are three main types of muntin configurations: True Divided Light (TDL), Simulated Divided Light (SDL), and Grilles Between the Glass (GBG). Each type offers a unique aesthetic and functionality.

Muntins can be made from various materials, including wood, vinyl, or metal, and can be used in different configurations to suit specific design needs. In modern windows, muntins are often used to create a classic, segmented appearance.

Mullions, on the other hand, are vertical or horizontal bars that separate and support multiple window units within a larger window opening. They provide structural support between separate windows and can be made from various materials, including wood, metal, and vinyl.

Here are the three types of mullions:

The Modern Farmhouse style is all about blending sleek, contemporary lines with a cozy farmhouse vibe. This look is achieved by incorporating multi-paned windows, lap siding, natural textures, and gabled roofs.

These traditional elements are balanced by modern touches like light color palettes and industrial lighting. This combination creates a unique and inviting atmosphere.

A key feature of Modern Farmhouse styles is the abundance of windows and moveable glass doors that allow natural light to pour in and connect the indoors to the outdoors.

Paned windows are a staple in modern architecture, and their significance can't be overstated. They provide the necessary structural integrity to support large windows.

Mullions, a crucial component of paned windows, are a key design element that offers visual breaks in the glass. This design element contributes to the building's overall aesthetic.

In buildings with large expanses of glass, mullions are essential for structural integrity.

The Tudor style home is a unique blend of Renaissance and Gothic architecture. It's characterized by decorative exposed timbers and vertical lines used throughout the design.

Tudor windows are a distinctive feature, using multiple panes of square-cut glass positioned diagonally within the frame. This creates a striking contrast to the bold straight lines created by the timbering.

Elaborate chimneys, irregularly-shaped rooms, and embellished doorways are often used to add visual interest to a Tudor-style home. These design elements add a touch of whimsy and personality to the space.

The use of transom windows can also create subtle line "breaks" within the design, adding to the overall sense of depth and complexity.

High Federal Style Residential windows were a hallmark of the upper class in New England during the 19th century.

The transformation of Georgian architecture to Federal style is exemplified in the new muntin profiles of these windows, which significantly narrowed the width of the muntin without sacrificing strength.

The depth of the muntin was increased, allowing for larger glass panes to be used. This was made possible by developments in glass production that made larger glass panes more affordable.

The result was a striking enlargement in the area devoted to the glass lights and a perceived reduction in the mass of the muntin.

The Kirk Boott House, built in 1823, features a High Federal Style Residential window that exhibits the most current architectural style of the time.

The window sash are counterbalanced, the muntins are characteristically thin, and the panes measure 12 by 18 inches, considerably larger than those of typical Georgian windows.

This window had its full complement of features, including interior shutters, paneled apron, wall reveals, and molding surround.

The 1830s Vernacular Residential style is characterized by simple design and detailing. This style is exemplified in a wood window from the Boott Cotton Mills' Boarding House Block Number 7, which has a sash opening of 31-1/4" x 52".

The window features a plank frame and incorporates one fixed sash (upper) and one moveable sash (lower), which are simple features that distinguish it from higher style contemporaries. This can be seen in the comparison to the 1820s Kirk Boott House.

The window has two six-light sashes, which is a common feature of vernacular Federal style windows.

The 1840s Greek Revival style was a popular architectural trend in Lower Manhattan, particularly in the South Seaport District. Commercial buildings from this era featured upper stores of brick surmounting granite trabeated ground floors.

Windows in commercial buildings during this time retained a residential scale, with double-hung six-over-six wood windows being a common sight. This style of window had a six-light sash with slender ovolo muntins.

The sash rails and stiles used in commercial buildings during the Greek Revival period were thicker than earlier windows, measuring 1-1/2" to 1-3/4" thick. Exterior casings were less decorated than on earlier windows.

Most windows from this era received counterweights and hardware at the time of construction, unlike Federal period warehouse windows which often lacked these features.

The Victorian style is all about vertical proportions, with rooms and houses tending to be tall, so windows can be tall too.

In fact, windows of this era often have a 2-over-2 muntin configuration, thanks to advancements in glassmaking technology that made large panes of glass possible.

A new generation of architects broke with earlier conventions, often grouping windows together, which added to the variety and asymmetry of this house form.

Building forms were more complicated, with multiple gabled or hip roofs, bay windows, and porches, which happily accommodated a wide variety of window sizes and groupings.

Ornamentation was highly favored during this time, with trim and panels around windows taking on a marked exuberance, and stained glass feature windows were common, especially in stairways.

To tie multiple window sizes together visually, it's essential to keep the glass panes in the windows proportional to each other.

The Craftsman style is a beautiful and functional architectural era that emerged during the early 20th century. Characterized by horizontal proportions, broad gables, and wide overhanging eaves, these houses often have a single-story appearance with additional living space tucked away in a large second-level attic.

One of the distinctive features of Craftsman-style windows is the use of muntins, which divide the glass into smaller panes. A 6-over-1 or 4-over-1 muntin configuration allows for an unobstructed view through the single-lite lower sash while providing visual interest from the smaller panes in the top sash.

Cottage-style windows, with a bottom sash that's taller than the upper sash, were commonly used in combination with conventional equal-height sash windows to unify windows of different heights visually. These two window types work well together when the upper sashes of both are the same height and align, even if the sills don't.

Dormers are a typical feature of the Craftsman style, and it's essential to size them so they appear subordinate to the roof. Positioning multiple narrower windows with muntins can help reduce the scale and make the windows seem smaller.

If you're looking to replace windows in a Craftsman-style house, consider using muntins to unify a window assembly with a wider center window and two narrower flankers. This can create a harmonious look by making each lite the same size, even if the glass is divided differently in the wider window.
