Bay window glazing in Crosspool, Sheffield
Bay window glazing in Crosspool is common for a simple reason: the area is inter-war and post-war, and three or five facets projecting from the elevation, splayed or square, often two storeys high is exactly what that period built. The problem we are asked to solve is the bay is a huge glazed area with mullions at odd angles and rarely a right angle anywhere. Crosspool 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. Crosspool is about 3 miles from central Sheffield, so a survey here is a short run for our team off the M1 J33.
Local conditions we design around
Bay angles vary house to house and often within a single terrace; the templating stage is what separates a clean install from a packed-out one.
Panels meet on the mullion lines so the bay reads as a bay rather than as a flat screen across the recess.
Crosspool stock is inter-war and post-war and the prevailing glazing is casement and picture windows, which is why bay window glazing comes up here so often.
Every facet is measured separately and the angles are recorded — bay angles are almost never the 45 degrees people assume.
Crosspool carries no conservation designation, so the specification is decided on performance alone.
What we actually fit
| Window type | three or five facets projecting from the elevation, splayed or square, often two storeys high (Victorian, Edwardian and 1930s bay-fronted housing) |
|---|---|
| Underlying problem | the bay is a huge glazed area with mullions at odd angles and rarely a right angle anywhere |
| System we fit | multi-panel horizontal sliders templated facet by facet |
| Glass specification | Low-E for comfort-led jobs, laminated on the front-facing facets where the bay looks onto a road |
| Measurement | every facet is measured separately and the angles are recorded — bay angles are almost never the 45 degrees people assume |
| Heritage position | on a bay-fronted terrace in a conservation area, room-side glazing is usually the only route that gets consent at all |
One survey, one fitting team, no subcontracted installers.
Every opening is templated on site — we do not price secondary glazing by the square metre.
We survey with a sound level meter where noise is the driver, so the target is a number rather than an impression.
Measured performance figures come from our own post-install testing, not manufacturer maximums.
How the job runs
- Step 1
Send a photo of the window — with three or five facets projecting from the elevation we can usually tell you the likely system before we visit.
- Step 2
Survey in Crosspool: every facet is measured separately and the angles are recorded — bay angles are almost never the 45 degrees people assume.
- 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.

Most clients start with one room and extend later — the pricing works either way. Send a photo of the bay window glazing — with three or five facets projecting from the elevation in a inter-war and post-war Crosspool property we can usually spec it before we visit.
Common questions
Can secondary glazing follow a bay?
Yes. Each facet gets its own panel and they meet at the mullions, so the shape of the bay is preserved from inside.
Is it cheaper to screen straight across the bay?
Slightly, but it looks like a screen and you lose the recess and the cill space. We only recommend it where the bay is behind a permanent piece of furniture.
How many panels will I need?
One per facet as a rule, so three or five, occasionally more if a single facet is wider than the maximum panel width.
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.
