Crittall glazing in Rossington, Doncaster
Around Rossington Colliery site, Rossington still carries a lot of original glazing — PVCu double glazing. Where those are 1920s–1960s, and again in modern conversions the failure mode is predictable: steel conducts heat straight through the frame, so the frame itself is the cold bridge, not just the glass. Rossington 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. Our vans are in Doncaster most weeks; Rossington is roughly 6 miles out from the centre, comfortably inside the South Yorkshire coverage area.
Survey notes from the area
Steel frames deflect under wind load on exposed elevations, and a sealed room-side pane removes the whistle that causes.
We align the secondary sightlines with the existing glazing bars where possible so the grid pattern still reads from inside the room.
Rossington stock is colliery village with large new-build estates and the prevailing glazing is PVCu double glazing, which is why crittall glazing comes up here so often.
Steel frames rarely sit true, so every opening is templated individually rather than batched.
Rossington carries no conservation designation, so the specification is decided on performance alone.
What happens next
- Step 1
Send a photo of the window — with slim galvanised or painted steel frames with small rectangular panes and thin glazing bars we can usually tell you the likely system before we visit.
- Step 2
Survey in Rossington: steel frames rarely sit true, so every opening is templated individually rather than batched.
- 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 goes in, and why
| Window type | slim galvanised or painted steel frames with small rectangular panes and thin glazing bars (1920s–1960s, and again in modern conversions) |
|---|---|
| Underlying problem | steel conducts heat straight through the frame, so the frame itself is the cold bridge, not just the glass |
| System we fit | slim-profile hinged or sliding units set to preserve the grid pattern |
| Glass specification | Low-E glass with a wide cavity, because the frame conduction dominates the heat loss |
| Measurement | steel frames rarely sit true, so every opening is templated individually rather than batched |
| Heritage position | original Crittall units are increasingly valued and often retained deliberately; a room-side pane lets you keep the look and fix the performance |

We will tell you when secondary glazing is the wrong answer — it happens, and it saves everyone time.
A whole-house residential install is normally completed within a single working day.
Thermal figures quoted are whole-window, not centre-pane, which is the honest way to state them.
Glass specification is decided after the survey, not before — the same room can need two different thicknesses.

Common questions
Why do my Crittall windows run with water?
Because the steel frame conducts heat out and drops well below room dew point. The water forms on the frame as much as the glass, which is why re-glazing alone does not solve it.
Will I lose the Crittall look?
No — the original stays in place and visible, and we align the secondary sightlines with the existing bars so the grid still reads.
Can you fit to rusted or distorted steel frames?
We fix to the reveal, not to the steel, so frame condition does not limit the install. We will flag any frame that needs remedial work first.
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.

Crittall glazing in Rossington — the short version
Steel conducts heat straight through the frame, so the frame itself is the cold bridge, not just the glass. We fit slim-profile hinged or sliding units set to preserve the grid pattern with Low-E glass with a wide cavity, because the frame conduction dominates the heat loss, templated to your opening. The cold-bridging frame is taken out of contact with room air, which is what stops the running condensation these windows are notorious for.
