What sets our georgian bar windows apart in Desborough.
Through-Frame Astragal Bars
The bar physically passes through the sealed glass unit — the most convincing option and the one most likely to secure planning consent in conservation areas.
18mm or 25mm Profile
Two heritage widths — 18mm for slimmer Regency and Victorian proportions, 25mm for the deeper bars typical of Georgian and Edwardian properties.
Duplex-Butt Jointing
Bar intersections are mechanically jointed rather than moulded — the joint has the same visual weight as the surrounding bar, exactly as a real timber glazing bar would.
Any Layout
6-over-6, 8-over-8, 6-over-1 (Victorian sash), 2-over-2 (Edwardian), diamond, marginal-light — matched to the age and style of the property.
Lead-Effect Upgrade
Lead-effect and stained-glass upgrades for Arts & Crafts, Victorian villa and cottage-style properties. Coloured, textured and etched glass available.
Across All Three Ranges
Available on uPVC, aluminium and flush-casement — the bar profile and jointing are consistent regardless of which material you specify.

- Do you handle conservation-area planning in Desborough?
- Northamptonshire's ironstone villages need windows that respect the building — deep reveals, heritage colours, subtle profiles. Our flush casements and painted composite doors have been accepted throughout the county's conservation areas. We prepare planning-ready drawings with matched sightlines, glazing-bar depths and hardware for Desborough projects that require them.
- What guarantee covers georgian bar windows in Desborough?

- Can I see recent georgian bar windows work near Desborough?
- Yes — we can share recent georgian bar windows case studies from across Northamptonshire, including projects in Braybrooke, Rushton and neighbouring towns. Ask your surveyor at the on-site visit.
- What thermal performance does georgian bar windows achieve in Desborough?
- Energy-efficient georgian bar windows installed across Desborough, Northamptonshire achieve whole-window U-values of 0.9–1.4 W/m²K, with the exact frame and glazing specification confirmed after survey.
- Which bar option is most authentic?
- Through-frame 18mm astragal bars with duplex-butt jointing at the intersections — the bar physically passes through the sealed glass unit rather than being applied internally or externally. It is the most convincing option and the one most likely to secure planning consent in a conservation area.
- What's the difference between astragal and Georgian bars?
- Colloquially they refer to the same thing — a bar that visually divides a window into smaller panes. Strictly, an astragal is the moulded profile of the bar itself; Georgian refers to the layout (typically 6-over-6). Our bars are moulded astragal profiles in the classical Georgian, Regency and Victorian layouts.
- Do bars reduce thermal performance?
- Through-frame bars reduce whole-window U-value by roughly 0.1 W/m²K vs an equivalent bar-free unit. Internal-grille and external-applied bars have no thermal penalty because they don't cross the sealed unit.
