Authentic 20mm Astragal Bars

- Do you handle conservation-area planning in Earls Barton?

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 Earls Barton projects that require them.
- What guarantee covers heritage steel-look windows in Earls Barton?

- Can I see recent heritage steel-look windows work near Earls Barton?
- Yes — we can share recent heritage steel-look windows case studies from across Northamptonshire, including projects in Great Doddington, Ecton and neighbouring towns. Ask your surveyor at the on-site visit.
- What thermal performance does heritage steel-look windows achieve in Earls Barton?
- Energy-efficient heritage steel-look windows installed across Earls Barton, Northamptonshire achieve whole-window U-values of 0.9–1.4 W/m²K, with the exact frame and glazing specification confirmed after survey.
- Is this the same as a real Crittall window?
- It's an aluminium replica of a Crittall — the appearance is very close but the frame is thermally-broken aluminium rather than steel. Original Crittall (rebranded W20 or Corporate W20) is still available in real steel, with worse thermal performance and additional maintenance requirements.
- Are they suitable for a listed building?
- Sometimes — where the original windows were steel and the officer accepts an aluminium replacement. Some listed properties will require true steel; we can quote both options at survey.
- How is thermal performance vs the original?
- Substantially better. Original steel windows had U-values around 5.0 W/m²K and cold bridged badly. Our aluminium heritage profile achieves 0.9–1.4 W/m²K and eliminates the internal cold bridge entirely.
