Sash window glazing in Treeton, Rotherham
If your Treeton 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 S60 is usually parkway noise and consent questions near the church, and the draught through the weight pockets is sealed and the original sash keeps operating normally. 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 Many of these calls come shortly after purchase, when the first winter has made the window problem obvious. Coverage runs across Rotherham and the surrounding S60, S61, S62 districts, with Treeton (S60) among the areas we survey most often.
Why this area is different
We avoid any fixing into the pulley stile or staff bead, so the install is fully reversible for a future owner or a conservation officer.
A sash box is a ventilated void by design; most of the perceived draught comes through the pulley stiles rather than through the glass.
Treeton stock is medieval church village with colliery terraces and the prevailing glazing is stone-lintelled 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.
Treeton is a conservation area: 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.
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 |
One survey, one fitting team, no subcontracted installers.
A whole-house residential install is normally completed within a single working day.
Glass specification is decided after the survey, not before — the same room can need two different thicknesses.
We survey with a sound level meter where noise is the driver, so the target is a number rather than an impression.

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.
