What sets our heritage steel-look windows apart in Shefford.
Authentic 20mm Astragal Bars
Slim mechanical grid bars that replicate original steel window proportions — 20mm on horizontal and vertical intersections, applied through-frame with duplex-butt jointing.
Matte Black Powder Coat
The signature finish — RAL 9005 matte black powder coat, or any RAL to match architect specification. Qualicoat Class 2 guaranteed for 20 years.
Thermally-Broken Aluminium
34mm polyamide thermal break inside the aluminium profile — no cold bridge, no condensation, U-values from 0.9 W/m²K. The original steel windows had none of this.
Casement or Fixed
Available as side-hung casements, top-hung vents, fixed lights and French pair configurations — matched across a full elevation.
Art Deco & Modernist Suited
The right window for warehouse conversions, factory conversions, 1930s Art Deco villas and contemporary modernist new-builds — anywhere a heavy timber sash would feel wrong.
PAS 24 Secured Locking
Concealed multi-point locking on all opening sashes and toughened inner glazing — modern security in a period-look frame.

- Can I see recent heritage steel-look windows work near Shefford?

- What thermal performance does heritage steel-look windows achieve in Shefford?
- Energy-efficient heritage steel-look windows installed across Shefford, Bedfordshire 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.
