Crittall glazing in Attercliffe, Sheffield
If your Attercliffe property has slim galvanised or painted steel frames with small rectangular panes and thin glazing bars, this page is the specification we would quote. The local brief in S9 is usually huge steel openings that lose heat faster than any other stock we see, and the cold-bridging frame is taken out of contact with room air, which is what stops the running condensation these windows are notorious for. Attercliffe is not a conservation area, so the decision is purely technical rather than a consent question. Many of these calls come shortly after purchase, when the first winter has made the window problem obvious. Coverage runs across Sheffield and the surrounding S1, S2, S3 districts, with Attercliffe (S9) among the areas we survey most often.
Why this area is different
We align the secondary sightlines with the existing glazing bars where possible so the grid pattern still reads from inside the room.
Steel frames deflect under wind load on exposed elevations, and a sealed room-side pane removes the whistle that causes.
Attercliffe stock is industrial and mill conversions and the prevailing glazing is large steel-frame factory openings, which is why crittall glazing comes up here so often.
Steel frames rarely sit true, so every opening is templated individually rather than batched.
Attercliffe carries no conservation designation, so the specification is decided on performance alone.

What we actually fit
| 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 |

Order of work
- 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 Attercliffe: 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.
Aluminium systems are powder-coated to any RAL colour at no extra lead time.
Installs are room-side only, so scaffolding is never needed and the exterior is untouched.
Thermal figures quoted are whole-window, not centre-pane, which is the honest way to state them.
Cavity depth does more for acoustic performance than glass thickness, and we design for it first.

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.
Which windows should we do first?
Whichever room you sleep or work in that faces the noise or the prevailing weather. We will say so honestly at survey rather than quoting the whole house by default.
Is it worth it if we might replace the windows later?
If replacement is likely within two years, usually not — we will tell you. If the frames are staying, secondary glazing is the cheaper route to the same comfort.
Crittall glazing in Attercliffe — 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.
