Secondary Glazing for Sash Window Homes Properties in High Green, Sheffield
High Green grew as northern edge suburb close to the Barnsley boundary, which is why sash window homes properties are so well represented here. They share one weakness: vertical box sashes of every era that were never specified for modern noise or heating standards. Most enquiries here come from owner-occupiers doing one or two rooms at a time, so we price per opening rather than per house. High Green is about 8 miles from central Sheffield, so a survey here is a short run for our team off the M1 J33.
Local conditions we design around
Sash reveals are rarely square, so every opening is templated on both diagonals before manufacture.
Both secondary sashes tilt in for cleaning, which keeps the cavity between the two windows free of the dust it collects each year.
Sash Window Homes properties date from the Georgian to Edwardian, and the original glazing is vertical box sashes of every era.
Sash rattle, draughts and irreplaceable glass — that is what we are asked to solve in High Green.
Local conditions matter: M1 corridor noise on exposed western elevations.
High Green sits 8 miles from central Sheffield, near High Green Park, so a survey visit is usually within the week.

How we would spec this
| Property type | Sash Window Homes (Georgian to Edwardian) |
|---|---|
| Original glazing | vertical box sashes of every era |
| Dominant problem | sash rattle, draughts and irreplaceable glass |
| Local window stock | casements and PVCu replacements |
| Consent position | No conservation designation recorded for this area, so the choice is technical rather than a consent question. |
Sash Window Homes glazing nearby
Every opening is templated on site — we do not price secondary glazing by the square metre.
Listed-building drawings and specifications are prepared free with the quote where consent is needed.
Measured performance figures come from our own post-install testing, not manufacturer maximums.
Common questions
Can Low-E glass be combined with acoustic laminated?
Yes — most heavy specifications combine both, so you get acoustic gain and thermal gain in the same install.
How is the quote calculated?
We survey and template every opening on site, then quote in writing per opening — no per-square-metre pricing that hides oversize charges.
Is there a warranty?
Yes — 10 years on the manufacture and installation, and a manufacturer's warranty on the glass units.
Can I still open the original window?
Yes — every sliding, hinged and lift-out unit is designed to move clear so you can operate the primary window behind it.
How does this compare to replacement double glazing?
A modern secondary unit with Low-E glass and a 100 mm cavity outperforms most existing sealed double-glazed units — and it works on windows you legally can't replace.
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.

Sash rattle, draughts and irreplaceable glass is the recurring issue in sash window homes stock, and in High Green it arrives alongside M1 corridor noise on exposed western elevations. A room-side secondary system handles both without touching the original windows.
