Secondary Glazing for Edwardian Semi Properties in Deepcar, Sheffield
Owners of a edwardian semi in Deepcar tend to ask us the same question, and the honest answer starts with the fabric: leaded top lights losing heat and rattling in bays. Around Deepcar Cemetery that shows up as cold deep reveals and damp corners in solid stone walls. Many of these calls come shortly after purchase, when the first winter has made the window problem obvious. Deepcar is about 8.5 miles from central Sheffield, so a survey here is a short run for our team off the M1 J33.
Aluminium systems are powder-coated to any RAL colour at no extra lead time.
Installs are room-side only, so scaffolding is never needed and the exterior is untouched.
Measured performance figures come from our own post-install testing, not manufacturer maximums.
How we would spec this
| Property type | Edwardian Semi (1901–1918) |
|---|---|
| Original glazing | bay windows with leaded top lights |
| Dominant problem | leaded top lights losing heat and rattling in bays |
| Local window stock | stone-mullioned casements |
| Consent position | No conservation designation recorded for this area, so the choice is technical rather than a consent question. |
Why this area is different
A three-panel horizontal slider sized to the bay opening keeps the leaded lights on show but adds a full thermal envelope behind them.
Low-E glass on the secondary pane lifts the whole bay's U-value without altering the historic frontage.

Common questions
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.
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.
Does it help with train and tram rumble?
It's very effective — the low-frequency energy is absorbed by the air-gap decoupling. A mismatched pane thickness widens the acoustic dip that train rumble usually punches through.
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.
