Arched Head Windows in Thame, Oxfordshire
Every arched head windows project we deliver in Thame starts with a senior surveyor on site — measuring, listening, and specifying to the character of Chinnor, Long Crendon and the wider Oxfordshire area. Radius, segmental and Gothic-arched windows CNC-cut to your survey template.
Arched Head Windows designed around Cotswold stone cottages, Oxford townhouses and painted heritage profiles.
Thame's mile-long High Street is one of the finest in the county, and the town's Georgian, Victorian and modern homes each need a different specification. We install throughout Thame, Chinnor, Long Crendon and Great Milton.

What sets our arched head windows apart in Thame.
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.

- Can I see recent arched head windows work near Thame?
- Yes — we can share recent arched head windows case studies from across Oxfordshire, including projects in Chinnor, Long Crendon and neighbouring towns. Ask your surveyor at the on-site visit.
- What thermal performance does arched head windows achieve in Thame?
- Energy-efficient arched head windows installed across Thame, Oxfordshire 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.
