What sets our arched head windows apart in Hatfield.
Radius, Segmental & Gothic
True radius (semi-circle), segmental (shallow arch), Tudor and Gothic (pointed) heads — CNC-cut to a survey template taken from the existing opening.
Template-Cut Precision
Every arched-head window is cut from a physical template surveyed on site — no assumptions, no gaps at the brickwork, no need to disturb the arch above.
Traceried & Divided
Arched heads can be divided by radial glazing bars, gothic tracery or curved astragal bars — matched to the period of the property.
Any Material
uPVC (fabricated on curved profile), aluminium (roll-formed) or heritage flush-casement — the material is chosen to suit the property, the head is cut the same way.
Modern Thermal Performance
Argon-filled A-rated glazing curved to the arch, warm-edge spacer bars and thermally-broken frames — U-values from 0.9 to 1.4 W/m²K on standard arched heads.
Chapels & School Conversions
The window we most often supply on chapel conversions, converted schools, Victorian bay fronts and stable-block conversions — properties where a rectangular replacement would look wrong.
What Hatfield homeowners tell us.
"A proper trade. Every promise kept — from the timescale to the finish. We've since recommended them to three neighbours."
"Slim aluminium sashes in anthracite grey — exactly the balance of period feel and modern lines we wanted. Conservation area approved."
"Punctual, quiet, tidy, honest. Three years on the front door still closes with that satisfying thud, and the paint finish hasn't moved."

- Do you handle conservation-area planning in Hatfield?
- The A1(M) and A41 corridor means Hertfordshire homeowners consistently benefit from acoustic-rated glazing. We spec triple-glazed and laminated options that transform a home's soundscape. We prepare planning-ready drawings with matched sightlines, glazing-bar depths and hardware for Hatfield projects that require them.
- What guarantee covers arched head windows in Hatfield?
- Every arched head windows installation in Hatfield is covered by our insurance-backed 10-year guarantee — parts, labour and finish. Aftercare is direct with the installing team, not a call centre.
- Can I see recent arched head windows work near Hatfield?
- Yes — we can share recent arched head windows case studies from across Hertfordshire, including projects in Old Hatfield, Ellenbrook and neighbouring towns. Ask your surveyor at the on-site visit.
- What thermal performance does arched head windows achieve in Hatfield?
- Energy-efficient arched head windows installed across Hatfield, Hertfordshire achieve whole-window U-values of 0.9–1.4 W/m²K, with the exact frame and glazing specification confirmed after survey.
- Do I need to remove the brickwork above the arch?
- No — we survey the internal arch profile with a template and cut the new frame to match. The masonry above stays completely undisturbed.
- Can the arched head be an opening light?
- Usually not — the curved head is a fixed light for structural reasons. Openings are placed in the rectangular section below the arch. On a large chapel-style window, we specify a radial opening light where head geometry permits.
- Can you match an existing Victorian bay-front arched window?
- Yes — we survey and template every arch individually, so even where original windows are inconsistent across a terrace we can match each one exactly. A single terrace of five bay-front houses might have five slightly different templates; we cut all five.
