Georgian bars and astragal bars are two distinct architectural elements commonly used in windows and doors to enhance their appearance, add structural integrity, and achieve specific design aesthetics. While they may seem similar at first glance, they serve different purposes and have distinct characteristics. So, in this guide, we’ll let you know the key differences between Georgian bars and astragal bars in detail, touch on their history, functionality, design variations, and practical applications.
One way to remember the difference between Georgian and astragal bars is:
‘Georgian-IN’ – Georgian bars are inside the glass.
‘Astragal-OUT’ – Astragal bars are outside of the glass panes.
History:
Georgian Bars:
Georgian bars derive their name from the Georgian architectural style, which was prevalent during the 18th century in Britain and its American colonies.
This style is characterised by a sense of symmetry, proportion, and classical design elements, and it heavily influenced window and door designs of the era.
Georgian bars were originally developed to mimic the appearance of muntins in the traditional divided-light windows, which were common in earlier architectural styles.
Astragal Bars:
Astragal bars have a longer history, dating back to ancient architecture.
The term “astragal” itself is derived from the Latin word “astragalus,” which referred to a type of moulding used in ancient architecture.
Astragal bars were traditionally used to divide panes of glass in windows and doors, providing structural support and aesthetic appeal.
Function:
Georgian Bars:
Georgian bars primarily serve as a decorative element in modern windows and doors.
These days they are typically manufactured within a double-glazed pane of glass, creating the illusion of divided lights without the need for multiple smaller panes.
Georgian bars do not provide structural support or divide the glass physically.
Astragal Bars:
Astragal bars serve both functional and decorative purposes.
They are used to physically divide the glass into smaller panes, providing additional support and security.
Astragal bars can also contribute to the overall aesthetic of the window or door – adding character and charm to a window.
Design Characteristics:
Georgian Bars:
Georgian bars are typically thin, linear elements made inside a double-glazed pane of glass.
They’re mostly made from PVC, but can also be made from materials like wood, or aluminium and come in various profiles, including flat, contoured, or moulded.
The design of Georgian bars can vary to match specific architectural styles, but they usually create a grid-like pattern in the glass.
Astragal Bars:
Astragal bars are typically thicker and more substantial than Georgian bars.
Likewise, they can be made from materials like wood, metal, or PVC and can be customised in terms of size and shape.
Astragal bars physically divide the glass into individual panes, with each bar running vertically and horizontally to create a grid-like pattern.
Practical Applications:
Georgian Bars:
Georgian bars are commonly used in modern windows and doors to achieve a traditional or colonial architectural aesthetic.
They are often found in residential settings where homeowners want the look of divided lights without the structural complexities of true divided-light windows.
Astragal Bars:
Astragal bars are used in a wide range of applications, including residential, commercial, and industrial settings.
They are ideal for situations where structural integrity and security are important, such as exterior doors and windows.
Astragal bars are often seen in historic buildings where authenticity and preservation of architectural features are crucial.
Installation and Maintenance:
Georgian Bars:
The glass manufacturer will install Georgian bars into the double-glazed unit.
Maintenance would involve occasionally cleaning the glass – simple!
Astragal Bars:
Installing astragal bars can be more complex, as they involve the placement of multiple bars within a window or door frame to divide the glass. Our manufacturers pre-install this for you, so you don’t have to worry about installing the bars yourself.
Maintenance basically just includes the occasional clean with a damp cloth and inspection to ensure the bars are secure and not damaged.
Customisation:
Georgian Bars:
Georgian bars offer a degree of customisation in terms of material, profile, and finish.
Homeowners can choose from various bar widths, colours, and configurations to match their design preferences.
Astragal Bars:
Astragal bars offer a high level of customisation since they can be tailored to the specific dimensions and design requirements of a project.
Architects and builders can select the number, size, and arrangement of bars to achieve the desired look and functionality.
Cost Considerations:
Georgian Bars:
Georgian bars are often more cost-effective compared to astragal bars, as they are primarily decorative and do not require the same level of structural modifications to the window.
Astragal Bars:
Astragal bars can be more expensive due to their functional role in dividing glass and the potential need for additional structural support.
Aesthetics:
Georgian Bars:
Georgian bars are best suited for projects where the primary goal is to create a traditional or historical appearance.
They are favoured for their ability to provide the look of divided lights without compromising energy efficiency or maintenance.
Astragal Bars:
Astragal bars are versatile and can be used in various architectural styles, including modern and industrial designs.
They are chosen for their structural benefits and can contribute to a sense of security in a building.
Georgian bars and astragal bars are distinct architectural elements with different functions, historical backgrounds, and design characteristics. While Georgian bars are primarily decorative and mimic the appearance of divided lights, astragal bars serve both functional and decorative purposes by physically dividing the glass into smaller panes. The choice between the two depends on the specific requirements of a project, including design preferences, structural needs, and budget constraints. Both types of bars contribute to the overall aesthetics and functionality of windows and doors, enhancing the beauty and performance of architectural spaces.
