Astragal Bars vs Georgian Bars: What’s the Difference?

What are Georgian bars?

Georgian bars are decorative glazing bars positioned inside the sealed glass unit, between the panes of glass.

Rather than actually dividing the window into separate pieces of glass, the bars create the appearance of multiple smaller panes while retaining the benefits of a modern sealed glazing unit.

The result is a traditional Georgian-style appearance, but with a completely smooth glass surface on both sides.

The benefits of Georgian bars

There are several reasons why Georgian bars remain popular:

• Clean, traditional appearance
• The glass remains completely smooth
• Easy to clean
• No external bars to catch dirt
• Can be incorporated into modern double or triple-glazed units
• Available in different layouts and widths
• Particularly suited to period-style and heritage-inspired properties

Because the bars are contained within the sealed glass unit, Georgian bars are a good choice if you want the traditional look without the additional cleaning associated with surface-mounted bars.

What are astragal bars?

Astragal bars provide a more three-dimensional appearance.

They are fitted to the surface of the glass, normally on both the inside and outside, with a corresponding spacer/bar arrangement within the glazing unit.

This gives the impression that the window is made up of individual panes, much more closely replicating the appearance of traditional timber windows.

When viewed from outside, astragal bars have a raised profile and create stronger shadow lines and definition across the glass.

This is why they are particularly popular on:

• Period properties
• Victorian and Edwardian-style homes
• Traditional cottages
• Heritage-style new builds
• Properties where an authentic appearance is important
• Aluminium windows designed to replicate traditional timber windows

Georgian bars vs astragal bars – what’s the difference?

The easiest way to understand the difference is to think about where the bar is located.

Both options can create a beautiful traditional appearance, but astragal bars generally provide the more authentic look because you can physically see and feel the raised glazing bars.

Can Georgian and astragal bars be fitted to triple glazing?

Yes — Georgian bars can be incorporated into triple-glazed units, provided the chosen glazing system and bar configuration are compatible.

Astragal bars can also be available with triple glazing, but this is more dependent on the particular window and glazing system.

Triple-glazed units are thicker than standard double-glazed units, so the available space and the way the bars are manufactured and fitted needs to be considered at the design stage.

This is particularly important if you’re looking for aluminium triple-glazed windows with astragal bars.

Rather than assuming that every astragal bar design will work with every triple-glazed unit, we recommend checking the exact combination before ordering.

At Aluminium Projects, we can advise you on the glazing configuration and decorative bar design that will work with your chosen aluminium window or door system.

Which looks more authentic?

If authenticity is your priority, astragal bars are usually the better choice.

The raised bars create stronger definition and shadows across the glass, helping modern aluminium windows replicate the appearance of traditional timber windows.

This can make a significant difference when replacing original windows on an older property.

Georgian bars, however, offer a cleaner and more understated appearance. Because they sit inside the sealed glazing unit, the outside of the glass remains completely flat.

For a modern home where you want to introduce traditional detailing without making the windows look too ornate, Georgian bars can be an excellent choice.

Are Georgian or astragal bars suitable for aluminium windows?

Absolutely.

Decorative glazing bars can be used with many modern aluminium window and door systems, allowing you to combine traditional styling with the benefits of modern aluminium.

This is particularly useful for homeowners in Derbyshire and South Yorkshire who want the appearance of traditional windows but don’t want to compromise on:

• Thermal performance
• Security
• Low-maintenance materials
• Modern glazing technology
• Slim aluminium sightlines
• Durability

For example, a contemporary aluminium window can be given a completely different character simply by changing the glazing configuration and adding a Georgian or astragal bar design.

Which should you choose for your home?

There isn’t one answer that is right for every property.

We normally recommend considering three things:

1. The style of your property

A period property, cottage or traditional-style home may benefit from the stronger, more authentic appearance of astragal bars.

A modern property may suit the cleaner appearance of Georgian bars.

2. How much maintenance you want

If easy cleaning is important, Georgian bars have an advantage because the glass remains smooth.

Astragal bars create additional surfaces that need cleaning, but the visual effect can be worth it if authenticity is your priority.

3. Your glazing requirements

If you’re considering triple glazing, the bar design needs to be considered alongside the glazing specification.

Not every decorative bar configuration is suitable for every triple-glazed system, so it’s worth discussing this before the windows are manufactured.

Georgian and Astragal Bars in Derbyshire & South Yorkshire

If you’re replacing windows in Dronfield, Chesterfield, Sheffield, Bakewell, Matlock, Buxton, Eckington, Holmesfield, Bolsover, Worksop or elsewhere across Derbyshire and South Yorkshire, decorative glazing bars can be an excellent way of adding character to new aluminium windows and doors.

They are particularly effective when you’re trying to retain the traditional appearance of an older property while upgrading to modern glazing and aluminium frames.

And if you’re considering triple glazing, don’t assume that you have to sacrifice the traditional look.

With the right window system and glazing specification, it may be possible to combine triple glazing with Georgian bars — and, in suitable systems, astragal bars too.
