Sash window glazing in Burngreave, Sheffield
If your Burngreave property has two vertically sliding sashes running in a boxed frame, usually with a horn detail on the upper sash, this page is the specification we would quote. The local brief in S3 is usually fuel-poverty-driven heat loss through very large single-glazed sashes, and the draught through the weight pockets is sealed and the original sash keeps operating normally. Burngreave 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. We cover S3 continuously — Burngreave sits within reach of the Ring Road (A61), which is also the reason a lot of these calls are about noise.
Survey notes from the area
A sash box is a ventilated void by design; most of the perceived draught comes through the pulley stiles rather than through the glass.
Matching the secondary unit's movement to the original means the window still behaves like a sash from inside the room, which matters in a period interior.
Burngreave stock is high Victorian terraces and the prevailing glazing is tall one-over-one sashes, which is why sash window glazing comes up here so often.
We measure the reveal at three heights because sash openings are rarely square after a century of settlement.
Burngreave carries no conservation designation, so the specification is decided on performance alone.
The technical answer
| Window type | two vertically sliding sashes running in a boxed frame, usually with a horn detail on the upper sash (Georgian, Victorian and Edwardian, roughly 1750–1910) |
|---|---|
| Underlying problem | the sash box is hollow and the counterweight pockets leak air, so the loss is around the window as much as through it |
| System we fit | vertical sliding secondary units that mirror the original movement |
| Glass specification | 4 mm Low-E for thermal-led jobs, 6.4 mm laminated where noise is the driver |
| Measurement | we measure the reveal at three heights because sash openings are rarely square after a century of settlement |
| Heritage position | nothing is fixed into the sash box itself — the frame is fixed to the reveal lining, so historic joinery is untouched and the work is reversible |
A whole-house residential install is normally completed within a single working day.
Aluminium systems are powder-coated to any RAL colour at no extra lead time.
Glass specification is decided after the survey, not before — the same room can need two different thicknesses.
Thermal figures quoted are whole-window, not centre-pane, which is the honest way to state them.

Common questions
Will secondary glazing stop my sash windows rattling?
Yes, and it does it without touching the sash. The rattle is wind pressure moving a loose sash in its box, and a sealed room-side pane removes the pressure differential driving it.
Can I still open the sash behind it?
Yes. Vertical sliding secondary units move on the same axis, so both sashes stay operable.
Does it damage original joinery?
No. The fixing is into the reveal lining, not the sash box, and the whole system can be removed later without trace.
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.
