Yes, Georgian bar windows can be more expensive than standard windows. This is because they require additional manufacturing materials and labour to create and fit the bars, especially if the design is intricate or if you opt for external (astragal) bars. The exact cost will depend on factors like the window material (uPVC, timber, or aluminium), size, style, and the complexity of the grid pattern.

Georgian bars can be made from various materials, including uPVC, timber, or aluminium, to match the window frame.

• Internal Georgian bars: These are typically made from uPVC or wood and are cut to size and fitted inside the sealed double-glazed unit, between the two panes of glass. This creates the illusion of individual panes while keeping the glass surface smooth for easy cleaning.
   
• External Georgian bars (Astragal Bars): These involve both internal spacer bars within the sealed unit and additional decorative bars applied to the outside surface of the glass. These external bars are precisely cut, shaped, and then secured to the window with clips, tape, or adhesive to create a more authentic, three-dimensional look.

The main difference lies in their placement and resulting appearance:

• Georgian Bars (Internal): These are fitted inside the sealed double-glazing unit, between the two panes of glass. This provides a flat, smooth glass surface, making the window very easy to clean. They offer a heritage-inspired look with lower maintenance.
   
• Astragal Bars (External): These involve both spacer bars inside the double-glazing unit and additional decorative bars applied to the outside of the glass. This creates a more authentic, three-dimensional, and traditional appearance, truly mimicking individual panes. They are often preferred for period properties or in conservation areas for their historical accuracy. Due to the extra materials and labour, astragal bars are generally more expensive.

You might choose Astragal or Georgian bars for several reasons:

• Aesthetic Appeal: Both types add a timeless, classic charm to your home, replicating the traditional multi-pane look of Georgian-era windows. They significantly enhance kerb appeal.
• Period Authenticity: If you live in a heritage property, a period home, or a conservation area, these bars can help maintain the historical accuracy and architectural style of your property. Astragal bars, in particular, offer a highly authentic appearance.
• Modern Benefits: Despite their traditional look, these windows still offer all the benefits of modern double glazing, including excellent energy efficiency, enhanced security, and noise reduction.
• Maintenance (Georgian Bars): Internal Georgian bars are particularly easy to clean as the external glass surface remains smooth and unbroken.
