Casement glazing in Meersbrook, Sheffield
Around Meersbrook Park, Meersbrook still carries a lot of original glazing — vertical sashes. Where those are found across every period, dominant in interwar and post-war housing the failure mode is predictable: the opening light and the handle furniture project into the reveal, so clearance has to be designed in. Meersbrook 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. Coverage runs across Sheffield and the surrounding S1, S2, S3 districts, with Meersbrook (S8) among the areas we survey most often.
Local conditions we design around
Casement leakage concentrates at the meeting stile and around worn hinge packings, both of which a single sealed secondary panel bypasses entirely.
Where a top-hung vent is used daily we split the secondary into two panels so the vent stays reachable.
Meersbrook stock is Edwardian and the prevailing glazing is vertical sashes, which is why casement glazing comes up here so often.
We record handle and stay projection at survey because that dimension, not the glass, sets the cavity depth.
Meersbrook carries no conservation designation, so the specification is decided on performance alone.

Order of work
- Step 1
Send a photo of the window — with side-hung opening lights on hinges we can usually tell you the likely system before we visit.
- Step 2
Survey in Meersbrook: we record handle and stay projection at survey because that dimension, not the glass, sets the cavity depth.
- 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 | side-hung opening lights on hinges, often with a fixed pane and a top-hung vent (found across every period, dominant in interwar and post-war housing) |
|---|---|
| Underlying problem | the opening light and the handle furniture project into the reveal, so clearance has to be designed in |
| System we fit | hinged secondary units, or lift-outs where the original is rarely opened |
| Glass specification | 4 mm Low-E as standard, 6.4 mm laminated on road-facing elevations |
| Measurement | we record handle and stay projection at survey because that dimension, not the glass, sets the cavity depth |
| Heritage position | on interwar stock the casements are usually not protected, which widens the specification options |

Every opening is templated on site — we do not price secondary glazing by the square metre.
We will tell you when secondary glazing is the wrong answer — it happens, and it saves everyone time.
Thermal figures quoted are whole-window, not centre-pane, which is the honest way to state them.
Measured performance figures come from our own post-install testing, not manufacturer maximums.
Common questions
Will the secondary unit foul the casement handle?
Not if the cavity is set from the hardware projection, which is what we measure on survey. It is the most common cause of a badly-fitting retrofit elsewhere.
Hinged or lift-out for a casement?
Hinged if you open the window regularly, lift-out if you do not — lift-outs are slimmer and cheaper but need somewhere to store the panel.
Can you cover a fixed light and an opener together?
Yes, usually with a two-panel unit so the opener stays accessible and the fixed light is sealed.
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.

Casement glazing in Meersbrook — the short version
The opening light and the handle furniture project into the reveal, so clearance has to be designed in. We fit hinged secondary units, or lift-outs where the original is rarely opened with 4 mm Low-E as standard, 6.4 mm laminated on road-facing elevations, templated to your opening. A single hinged panel seals the whole opening including the fixed light, which is where most of the leakage actually is.
