Bay window glazing in Kelham Island, Sheffield
Bay window glazing in Kelham Island is common for a simple reason: the area is converted 19th-century industrial, 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. on a bay-fronted terrace in a conservation area, room-side glazing is usually the only route that gets consent at all Mixed residential and commercial use around here means out-of-hours fitting is common and we quote for it as standard. Kelham Island is about 1 mile from central Sheffield, so a survey here is a short run for our team off the M1 J33.
Local conditions we design around
Panels meet on the mullion lines so the bay reads as a bay rather than as a flat screen across the recess.
A three-facet bay can carry more glazed area than every other window on the floor combined, which is why it dominates both the heat and noise picture.
Kelham Island stock is converted 19th-century industrial and the prevailing glazing is steel-frame factory glazing, 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.
Kelham Island is a conservation area: on a bay-fronted terrace in a conservation area, room-side glazing is usually the only route that gets consent at all.

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 Kelham Island: 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.
Installs are room-side only, so scaffolding is never needed and the exterior is untouched.
Aluminium systems are powder-coated to any RAL colour at no extra lead time.
We survey with a sound level meter where noise is the driver, so the target is a number rather than an impression.
Cavity depth does more for acoustic performance than glass thickness, and we design for it first.

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.
Can you work outside trading hours?
Yes. Evening, weekend and phased installs are routine and are priced into the quote rather than added later.
What about fire escape and means of escape windows?
Escape openings get hinged or lift-out units with a compliant catch, specified on a per-opening basis at survey.
