Sash window glazing in Kimberworth, Rotherham
We work on sash window glazing across Rotherham, and Kimberworth is one of the areas it comes up most. The sash box is hollow and the counterweight pockets leak air, so the loss is around the window as much as through it — which is why a room-side pane, rather than a replacement, is the answer here. Kimberworth 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. Our vans are in Rotherham most weeks; Kimberworth is roughly 1.5 miles out from the centre, comfortably inside the South Yorkshire coverage area.
Listed-building drawings and specifications are prepared free with the quote where consent is needed.
Every opening is templated on site — we do not price secondary glazing by the square metre.
Measured performance figures come from our own post-install testing, not manufacturer maximums.
We survey with a sound level meter where noise is the driver, so the target is a number rather than an impression.
What we find on these streets
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.
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.
Kimberworth stock is Victorian terraces and interwar semis and the prevailing glazing is sashes and casements, 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.
Kimberworth carries no conservation designation, so the specification is decided on performance alone.
How we would spec this
| 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 |

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.
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.
Start with one room — Windows
Send the opening sizes for the worst room and we will price that first — extending later costs no more.

Sash window glazing in Kimberworth — the short version
The sash box is hollow and the counterweight pockets leak air, so the loss is around the window as much as through it. We fit vertical sliding secondary units that mirror the original movement with 4 mm Low-E for thermal-led jobs, 6.4 mm laminated where noise is the driver, templated to your opening. The draught through the weight pockets is sealed and the original sash keeps operating normally.
