What sets our arched head windows apart in Marlow.
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 Marlow homeowners tell us.
"Insulated garden studio, fully wired, plastered and finished — six weeks from survey to keys. It reads as an extension of the house, not a shed."
"A 7m bifold set across the back of our Chiltern barn conversion. Faultless install, faultless finish. The traffic door is a small detail that we now use every day."
"Their surveyor drove out twice before we'd even signed anything. That's the level of care we hoped for and rarely find."
Common questions from Marlow homeowners.

- Most Marlow projects run to a two-to-eight week lead time from signed quote to install, depending on manufacture. Once on site, a typical arched head windows install completes in one to five working days with full dust-sheet protection and clean-down.
- Do you handle conservation-area planning in Marlow?
- Many of our Buckinghamshire projects sit within the Chilterns AONB or conservation areas. Our heritage flush casements and timber-effect finishes are frequently accepted where UPVC once wasn't. We prepare planning-ready drawings with matched sightlines, glazing-bar depths and hardware for Marlow projects that require them.
- What guarantee covers arched head windows in Marlow?
- Every arched head windows installation in Marlow 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 Marlow?
- Yes — we can share recent arched head windows case studies from across Buckinghamshire, including projects in Marlow Bottom, Little Marlow and neighbouring towns. Ask your surveyor at the on-site visit.
- What thermal performance does arched head windows achieve in Marlow?
- Energy-efficient arched head windows installed across Marlow, Buckinghamshire 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.
