When choosing aluminium windows & doors for homes or businesses, architects and homeowners frequently face a common design dilemma—should they opt for Georgian bars for windows or astragal bars? Both styles lend a classic beauty, yet each comes with its unique look and feel. But appearance isn’t the only factor. Selecting the right window bar influences durability, cost, thermal efficiency, and even maintenance.
Whether it’s renovating a heritage bungalow, designing modern apartments, or installing new commercial windows, understanding these differences simplifies your choice. So, let’s clarify exactly how window Georgian bars and astragal bars differ and which might suit your project best.
Meaning of Georgian Bars For Windows and Astragal Bars For Windows
What Are Georgian Bar Windows?
The Georgian architectural era popularised windows featuring multiple smaller glass panes divided by elegant wooden bars. Modern-day Georgian bar windows replicate this traditional style, but now with contemporary materials like aluminium. Unlike older wooden windows, these bars no longer physically divide the glass into separate panes. Instead, Georgian bars sit between or on the surface of double-glazed glass units, mimicking the original aesthetic without sacrificing modern benefits like insulation and strength.
Today, many residential aluminum window manufacturers incorporate Georgian bars to blend traditional aesthetics with practical, low-maintenance materials. Their neat look goes well with slimline, minimal aluminium window & door systems. Thanks to aluminium’s strength and flexibility, these bars fit neatly within sturdy aluminium window frames and seamlessly integrate with various home designs.

What Are Astragal Bar Windows?
Astragal bars take the traditional look one step further. While Georgian bars typically sit between glass panes or on one side, astragal bars are attached directly onto the exterior and interior surfaces of a single double-glazed unit. An internal spacer bar is also placed within the glass, creating the visual effect of separate panes. This gives a convincing divided-light look that closely resembles historic windows.
Astragal bars are popular among commercial aluminum window manufacturers and homeowners seeking authenticity. They’re often featured in high-end French doors and windows designs, custom-designed homes, and heritage renovations. These bars provide depth and character, perfectly suited for those wanting a more detailed finish

1. Construction and Design
Both Georgian and astragal bars aim to replicate traditional divided-light window styles but differ notably in construction methods.
Georgian bar windows are straightforward. They usually have bars placed between the panes of double-glazed glass or adhered directly onto the inner pane surface. This streamlined method results in fewer components so they’re easier to produce. Aluminium is frequently used for these bars, especially in commercial windows, due to its durability and versatility.
Astragal bars, however, require more intricate manufacturing. They’re fixed externally and internally onto a single glass unit with an internal spacer to reinforce the divided-pane appearance. While this design provides authentic aesthetics, it also involves additional labour and materials, typically raising costs. Still, top custom window manufacturers often recommend astragal bars for restoration projects because of their realistic charm.
2. Visual Effect and Aesthetic Appeal
Appearance plays a central role in choosing bars for windows. Georgian bars offer a clean, subtle design, suitable for modern homes wanting a nod to traditional aesthetics. The understated appeal makes them versatile for both contemporary and classic home styles, easily matching various architectural themes. These are popular among top window companies focused on streamlined elegance.
Astragal bars create a more pronounced visual impact. By physically protruding from the glass surface, they create shadows and depth, adding authenticity and sophistication. They often suit projects where visual detailing matters—heritage renovations, upscale residences, or historic windows and doors installations. Many leading window and door companies suggest astragal bars for projects demanding historical accuracy or period-drama aesthetics.
3. Functionality and Performance
Appearance aside, how these bars on windows perform matters significantly. Subtle performance differences exist between the two. Georgian bars typically offer slightly better thermal efficiency. Since bars placed between the panes don’t interrupt the surface, heat transfer remains minimal and insulation improves.
Astragal bars, though visually appealing, introduce additional surfaces and joints. These minor interruptions can affect overall insulation properties. Still, high-quality manufacturing processes used by reputed commercial window manufacturers lessen these issues considerably for efficient and visually striking results.
In terms of security and robustness, both types perform similarly, provided they’re manufactured and installed professionally.
4. Cost and Customization
Both Georgian bars for windows and astragal bars add character to aluminium windows & doors, but Georgian bars offer a cleaner, more versatile design. Integrated within double glazing, they suit luxury residential and commercial windows without disrupting insulation. Many commercial aluminum window manufacturers prefer them for their refined aesthetics and compatibility with slimline windows & doors paired with integral blinds.
Astragal bars, applied externally and internally, mimic traditional multi-pane windows but require detailed craftsmanship. Often used in heritage restorations, they add complexity. However, premium Georgian bars are favoured for their elegance, low maintenance, and seamless fit in aluminium window frames.
When Should You Choose Georgian Bars For Windows?

FAQs
What are Georgian window bars?
Georgian window bars are decorative elements that create the look of traditional multi-pane windows. In modern Georgian bar windows, these bars are placed within or on the surface of double glazing to preserve insulation while maintaining a classic aesthetic. They are commonly used in aluminium windows & doors, for a classy, elegant design without structural complexity.
What is the difference between Georgian bar and astragal bar?
Georgian bars for windows sit between or on the glass surface and create a seamless, low-maintenance design. Astragal bars, however, are fixed externally on both sides of the glass with an internal spacer so they have a stronger divided-pane effect. While both styles suit custom windows and doors, Georgian bars are often preferred for their refined appearance and practical luxury.
What is the spacer bar in a window?
A spacer bar is a structural component placed between glass panes in double-glazed aluminium windows & doors. It maintains an airtight seal, improves insulation, and betters durability. In astragal bar designs, the spacer bar is used to create the illusion of individual panes, while in Georgian bar windows, it helps maintain the grid effect without affecting performance.
Can you add Georgian bars to windows?
Yes, Georgian bars for windows can be added to existing aluminium window frames or integrated into new installations. They provide a classic grid design without altering the glass structure. They’re a popular choice in commercial windows and high-end residential projects. Many top window companies offer customization options to match architectural styles.
Can you remove astragal bars?
Unlike window Georgian bars, which are often placed between glass panes, astragal bars are externally applied. While removal is possible, it may require professional assistance, especially in custom windows and doors. Removing them can affect the aesthetic and structural integrity, so it’s best to consult commercial aluminum window manufacturers before making modifications.
