Secondary glazing for South Kensington homes
Around South Kensington you will mostly find stucco terraces, red-brick mansion blocks and converted period flats. Behind Victorian sash windows, vertical sliding secondary glazing aligned with the meeting rail keeps the view uninterrupted and lets both windows open for ventilation.
For flats where the lease or freeholder prevents changing external windows, secondary glazing fitted inside is usually the simplest way to reduce traffic noise and heat loss. On listed buildings, secondary glazing is often the preferred way to improve comfort, but check with the conservation officer as listed building consent may still be needed.
Where a building is listed, or the freeholder insists on keeping the original sashes, secondary glazing fitted inside the existing frames is usually the sensible answer, and it also helps with noise from Cromwell Road. We talk to managing agents about access, consent and parking bay suspensions before we fix a fitting date.
Secondary glazing is a discreet second window fitted on the inside of your existing windows, leaving the originals untouched. It suits listed buildings, conservation areas, flats where external windows cannot be changed, and anyone wanting to cut noise and draughts without replacing period windows.
- Keeps original windows in place
- Suitable where replacement is restricted
- Panels open or lift out for cleaning
Questions from South Kensington
Do I need planning permission for secondary glazing in South Kensington?
Nearly all of South Kensington is covered by Kensington & Chelsea conservation areas and many buildings are listed, so we confirm with the Royal Borough and the freeholder what is allowed before quoting; secondary glazing is often the route that avoids a planning application. Secondary glazing is fitted internally, so it does not usually need planning permission or Building Regulations approval, but listed buildings may need listed building consent first.
How soon can you fit secondary glazing in South Kensington?
Lead times vary by product and workload — confirmed with your quote. Being about 9.8 miles from our factory makes surveys, fitting days and aftercare visits easy to arrange.
Does secondary glazing really reduce noise?
It can make a noticeable difference, because the air gap between the original window and the secondary pane helps absorb sound. A wider gap and thicker or acoustic laminated glass generally improve performance. We'll look at your windows and the source of the noise to recommend the most effective setup.
Can I see samples before I decide?
Yes. Our showroom is at Unit G, 1 Anthony Way, London N18 3QT (Mon–Fri 8am–5pm), about 9.8 miles from South Kensington. We can also bring samples to your home in South Kensington at the free survey.
