Arched window glazing in Hasland, Chesterfield
We work on arched window glazing across Chesterfield, and Hasland is one of the areas it comes up most. The curved head has to be templated physically — a measurement cannot describe it — which is why a room-side pane, rather than a replacement, is the answer here. Hasland is not a conservation area, so the decision is purely technical rather than a consent question. Most enquiries here come from owner-occupiers doing one or two rooms at a time, so we price per opening rather than per house. We cover S41 continuously — Hasland sits within reach of the A61 Sheffield Road, which is also the reason a lot of these calls are about noise.
Survey notes from the area
Leaving the arch untreated and glazing only the rectangle below leaves a substantial open loss path at the top of the warmest air in the room.
An arched head cannot be described by width and height, so we take a physical template — a survey without one is guesswork.
Hasland stock is railway-era terraces and interwar semis and the prevailing glazing is bay sashes, which is why arched window glazing comes up here so often.
A physical template is taken of the arch — this is the one situation where we will not work from dimensions alone.
Hasland carries no conservation designation, so the specification is decided on performance alone.
Order of work
- Step 1
Send a photo of the window — with semi-circular we can usually tell you the likely system before we visit.
- Step 2
Survey in Hasland: a physical template is taken of the arch — this is the one situation where we will not work from dimensions alone.
- Step 3
Manufacture to the templated sizes with your chosen finish.
- Step 4
Room-side install with no external access and no alteration to the original frame.
What we actually fit
| Window type | semi-circular, segmental or pointed heads, sometimes with tracery in the arch (Victorian villas, chapels, schools and converted ecclesiastical buildings) |
|---|---|
| Underlying problem | the curved head has to be templated physically — a measurement cannot describe it |
| System we fit | curved-head units with the arch shaped to the opening, straight panels below |
| Glass specification | clear or Low-E in the arch so tracery stays legible, heavier glass in the working panels below |
| Measurement | a physical template is taken of the arch — this is the one situation where we will not work from dimensions alone |
| Heritage position | in converted chapels and schools the arch is invariably the reason the building is protected, so it stays untouched |

We will tell you when secondary glazing is the wrong answer — it happens, and it saves everyone time.
Installs are room-side only, so scaffolding is never needed and the exterior is untouched.
Glass specification is decided after the survey, not before — the same room can need two different thicknesses.
Measured performance figures come from our own post-install testing, not manufacturer maximums.

Common questions
Can secondary glazing follow an arched head?
Yes. The head is shaped from a physical template of the opening, and the panels below are conventional.
Is it much more expensive than a rectangular window?
The shaped head carries a premium because it is a bespoke component, but the panels below are standard, so the whole-window difference is smaller than people expect.
Will the tracery still be visible?
Yes — clear glass in the arch keeps it legible from inside the room.
Can we do one room now and the rest later?
Yes. We template and price per opening, so a later phase is quoted at the same rate — there is no penalty for splitting the work.
Will it get in the way of curtains or blinds?
Rarely. Reveal-fixed units sit inside the existing recess; where the recess is shallow we face-fix and reposition the blind, which we flag at survey rather than on the day.
Arched window glazing in Hasland — the short version
The curved head has to be templated physically — a measurement cannot describe it. We fit curved-head units with the arch shaped to the opening, straight panels below with clear or Low-E in the arch so tracery stays legible, heavier glass in the working panels below, templated to your opening. The whole opening including the arch is sealed rather than leaving the decorative head as an open loss path.
